Home projector LCD technology and the DLP technology

LCD and DLP projectors are the current mainstream technology, which technology is better? That there is no standard answer, it depends entirely on the applications. Techniques have strengths and key for consumers to understand their needs, understanding the characteristics of LCD and DLP each, on-demand options.

LCD projector is the LCD imaging device, when the light through the LCD panel, each pixel according to image signals are turned on or off, so that some light through, and some were cut off. By adjusting the light to produce the image projected onto the screen. The current mainstream LCD projectors have been used EPSON (Epson) 3LCD technology, which uses three LCD panels as imaging devices, optical system through the spectroscope the light was separated into red, green, and blue, individually for each a color brightness and contrast control, the performance of this color is very important. As the current 3LCD technology has been very mature, three-color light to reach the screen is almost the same time, so the control circuit in the high quality 3LCD projector, the projection is very good, bright true color reproduction, rich layers and color saturation.

The disadvantage of early LCD projectors, and now one by one to improve. Such as LCD projector prone to the grid phenomenon, with the EPSON has launched the first 5th generation high-temperature polysilicon panels and projectors to improve the resolution has been hard to detect and use the 5th generation high-temperature polysilicon panels can greatly improve the projector's resolution, to 1920 × 1080, support for 1080p high-definition mode really. Moreover, the light efficiency and contrast are greatly improved, with aperture-linked technology; 3LCD technology has been achieved up to 6000:1 contrast ratio, which is of great significance for video playback. As a whole, the best color performance to 3LCD projection technology for motion video playback, ideal for home theater applications.

DLP projector LCD projector for it is a rising star. It works completely different from the LCD projector; the light source of the light emitted by high-speed rotating color wheel produces red, green, and blue, followed by alternate exposure to the DMD (Digital Micromere Device, DMD) of the surface. DMD micro mirror surface according to their corresponding pixels in the light of the availability of such colors and off two positions in the high-speed switching, and finally, after reflection by the mirror, projected onto the projection screen to form images. As a way of using reflection imaging, contrast can be very high, very good uniformity. Because there is no convergence problems, especially in the projection in the text show some small font text or drawings shows the best. Well suited to text and form-based business or education market.
DLP projector as the main color is determined to rely on the color wheel; color processing speed is low, poor color reproduction, but also the rainbow effect, the overall color performance to be inferior to 3LCD technology. As technology improved, the current color wheel has changed from the original RGB to RGBW three-stage development of four sections, on the home that require high color DLP projector or used RGBRGB Six-color wheel, color processing speed increases, substantially reducing Little of the rainbow effect. But from a practical effect, most DLP products still lack the kind of real ideal brilliant colors.

Overall, in the current high-end home projector market, high-end DLP products with ultra-high contrast, good color enhancement technology to win the favor of some users; in the same price on the 3LCD products favorably in all respects, Even more unique to show the film "film sense" screen, they are points and weak points. In the end home mirco projector market, 3LCD color performance with cost advantage and win most of the users concerned.

Specifications and main technical about mini projectors

1. Technical Specifications
a). Dimensions
b). Optical efficiency: Unit power consumption (per watt) to the output of the luminous flux (lumens)
The index is an indicator of micro-projection is very important, as an ordinary projector, because supply is very important for the general brightness indicators, micro-projectors, both due to the brightness, battery life, heat and so on system problems, and therefore not simple brightness and the luminous efficiency will be as key indicators.
c). Resolution: The resolution of chips, such as VGA (640 * 480), QVGA (320 * 240) and so on.
d). color purity: color performance indicators, often internationally to measure the scope of NTSC color gamut
e). Contrast: easy to measure the image resolution indicator (a simple definition of state of dark state light display ratio)

2. DLP technology
As a Pocket Projector (mini-projector) of the main promoters, TI handheld projector in (pico-projector), also under the foot of the intensity, since 2008, the latest DLP also introduced its latest generation of the DMD chip.
Currently, in the world, only Texas Instruments (TI) DMD chip can provide the commercialization of products, mainly through the principle of the micro-mirror control to light to switch to achieve the right color scale and gray scale of that in the small DMD chip, with nearly 1 million than a human hair fine type of small mirrors.

3. LCoS Technology
DLP technology from TI with a company than monopoly, LCoS chip business, relatively speaking, more and more, such as Himax, Displaytech (Micron), Syndiant so. In addition, DLP LCoS technology platform open than many, relatively speaking, a greater development potential. LCoS technology as its main imaging principle similar to liquid crystal LCD, is controlled by micro-circuit voltage to liquid crystal torsion, polarized light through the LCD on the control, hitting the light to switch to achieve the color scale and gray scale. LCoS (Liquid Crystal on Silicon) and the LCD itself is different in that its reflectivity for light control, and LCD is the transmission of light control, so in theory LCoS technology itself from the opening rate would more than LCD.
As the LCoS technology, began to develop from 2008 to the present, there are the original color filter type (Color Filter) development for the current color sequence type (Color Sequential), its color performance and light use efficiency have been significantly improved current Sequential Color LCoS has become a mainstream technology.
Speaking LCoS technology and had to refer to the 3M Company, as the world's first release 3M, the optical engine is also a Fortune 500 company, its corporate culture is known for innovation in display technology field, from the projector Faming to the 2008 launch of the world's first optical engine, 3M Company has also become a big banner LCoS technology. In addition, 3M, liquid crystal polarization control in long-term technological leadership, which itself control the development of a polarization film, the film made use of PBS (Polarizing Beam Splitter) Polarization-controlled optical components, can make the same performance The LCoS light engine more than 30% volume reduction, process complexity greatly reduced, in addition, compared with the general LCoS light engine, can also contrast sharply.

How To Remove The Rear View Mirror

Question: how to remove and replace the interior rear view mirror im getting an eyebrow done on my windshield , but the place thats doing it does not want to remove the mirror, because they dont know what kind of electronics are involved with it and dont want to cause any damage any help would be great. thanks.

Answer1:Removes like a normal mirror..
you can’t remove the rain sensor, if you do it won’t work anymore, but the mirror is no big deal..
unplug the connectors and there is a t-15 or t-20 torx screw that holds it to the glass mount..

Answer2:From the Service Manual it looks like the sensor can be removed, but there is a mounting bracket that is bonded to the windshield. The mounting bracket is not meant to be removed.

Answer3: Removing the bracket and resinstalling it will have ill-effects on the rain sensor. as I understand it, it will not work correctly or at all because there is a specific angle and “trim” that has to be met for the sensor to “see” the rain..
my tint shop just cut around the rain sensor and they did a very good job at it, it looks like part of the tint strip..
same way they cut around the third brake light in the rear window.

Car owner essential supplies have?

After a lot of car owners buy the car and did not know what to buy a car essential supplies, resulting in their often chaotic buy a pass. Therefore, in order to resolve this situation, the first is to understand the use of each automobile supplies to see whether your car needs, in addition, as long as you put your heart, in fact, supplies of each car has a good way to save money. Here, we introduce four kinds of the most common automotive supplies.

1, anti-theft devices

Car anti-theft devices include electronic anti-theft lock and mechanical lock. The two are often used in conjunction. Since many domestic models are not original factory anti-theft, anti-theft equipment or provide the original imperfect, for example, there is no alarm, remote control, failure, etc., so most need to install electronic security.

Do not need groups: factory anti-theft feature perfect car, purchase a free gift.

Tips to save money: for safety and reliability requirements, electronic anti-theft device of choice must be selected manufacturers of quality and reliable brand. As for the function, if you want to save money, in fact, choose the simplest is enough. For example, two-way alarm, remote control and display features more than doubled expensive, but the practicality is not significant. As for the mechanical anti-theft device, in fact, the most simple and cheap to buy can be a mix of uses.

2, parking sensor

Not just for the novice, in fact, opened a lot of veterans for years cars often Mian Bude reversing some virtually scratch, this time reverse parking sensor can come in handy. Even the cheapest can not accurately display parking sensor, frequent drops in the sound, you will raise the attention of reversing. Rely on parking sensor reduces the number of car repair; it's actually a big saving.

Do not need groups: original function with a parking sensor models, and have full confidence in backup technology owners.

Tips to save money: parking sensor manufacturers have to choose some products, the error rate will be a small number. In fact, common features four parking sensor if you use familiar words, sufficient to meet the backup, and the price is very cheap. Many new long out of the radar, even with rear view camera, although the first function is really useful, but the prices are high a lot, does not meet the principles of family save money.

3, carpet

No matter the angle from the car's clean, visual effects, or comfort, the carpet is almost essential for all cars had one car supplies. The major difference is by how you have chosen.

Do not need groups: a car dealer have the carpet when presented.

Tips to save money: carpet prices vary greatly, most expensive energy approximation thousand dollars cheaper within the hundred, in fact, do not rely too much on brands to buy mats and materials for health point of view, you'd better have a year a change, in fact, within the automotive supplies market, 100 Yuan to buy the carpet is not bad and can be considered. Even if you like a number of high-grade materials, carpets, can also be a number of goods than to find the cheapest to buy, there is no technology to speak of these things, you can also play a DIY spirit; buy the most suitable material to make their own rugs.

4, perfumes and air cleaning products

Placed on the center console in the car a bottle of perfume has become the owner of one of their signature practices. In addition, small block of space in the car placed a number of perfume or air fresheners can also indirectly improve air quality.

Do not need groups: there is no smell inside the car, factory air-filter cleaning model.

Are pico projectors the next big cellphone trend?

While commercial products with so-called pico projectors are still relatively rare, Microvision and rivals such as Texas Instruments Inc and 3M Co were promising strong prospects for pico at the Las Vegas show which ends on Sunday.

Microvision showed off a stand-alone projector that looked like a big bar of soap and projected crisp video images using laser technology. Its big hope is to embed the technology in a range of consumer electronics including cameras and phones.

"My feeling is that ultimately the phone is the largest opportunity," Microvision's director of communications Matt Nichols said, adding that his company was talking to dozens of potential customers including phone makers.

Nichols sees the first prototypes of gadgets with embedded Microvision pico projectors later this year, and expects the first commercial products some time next year.

After that, he expects the market to explode -- in the same way that cameras have quickly become a must-have component in cellphones.

"We believe that in a five-year forecast, your phones will all have projectors," Nichols told Reuters.

Texas Instruments, a major supplier of application chips for phones, has its pico projectors embedded in several commercial devices including dedicated mini-projectors and two phones from Samsung Electronics Co Ltd, the latest of which was demonstrated at CES.

"Everybody is just completely jazzed about" pico projectors, said Frank Moizio, manager for Texas Instruments' pico business. "I don't know what that translates into in volume. We hope it will be high."

Since phones already have so many bells and whistles, such as multitouch screens, cameras and music and video players, some analysts question how much room there is to add more components.

But Ovum's Jonathan Yarmis says pico technology has a huge potential because it solves the problem of video viewing on tiny cellphone screens.

"When you liberate the display from the device, you've the opportunity to make the experience more immersive," the analyst said when asked about the next big cellphone trends.

Others like wireless industry consultant Cheetan Sharma see the mini-projectors turning up in cameras, allowing photographers to share snapshots, before becoming popular in cellphones.

"I think the camera is the first thing and then of course it will migrate to smartphones," Sharma said, adding that electronics makers also expect demand for pico projectors in laptops for business travelers. "Some people are looking to integrate it into a laptop so they can do presentations."

An Introduction to the New Visual Safety System of Cars

The automotive industry is affected by the economic crisis at the present time. Safety and environmental protection is becoming the orientation of its development, leading manufacturers to produce a satisfactory product.

Safety is the most important element of a new car to customer feedback. The security system can guarantee the safety of driver, passengers and pedestrians, and reduce the incidence of accident it is still rapid growth, such as advanced driver assistance. Apart from the airbag, the new active safety system also applies to automobiles increasingly. As the rear view system, care system alert, lane-warning system, light control system, anti-collision and so on. There is a growing urgency for the design of car environmental protection to reduce energy consumption and greenhouse gas emissions. Apart from traditional media, different types of replacement power is implemented, such as ethanol-powered vehicles, hybrid and electric vehicles and battery electric vehicle.

So let's get to know something about the security system monitor. The image transducer with high dynamic range and the system directory protocol to create a new era of automotive vision system. For example, the warning signal on the system rear view camera to ask the driver for the change in size and color, warning care system can record and analyze the movement of the eyes through the camera emits infrared acoustic signal when the driver's eyes is closing for a long period of time, the lane warning system can monitor vehicle position for the camera.

The security monitoring system is based on the above systems visible faces some challenges such as low environmental light intensity. Apart from the camera, high-speed parking sensor is one of the main components in the system of active safety. The visible system software has some shortcomings, despite the high speed can use the advanced semiconductor technology to meet the high demands of active safety system. Scientists are trying to use SiGe chips to radar design, especially the application of remote inspection of the cars.

Four methods to solve the problem windows aerosol affect sight

Many owners will encounter while driving such a problem: car started to open up some distance, the window glass was covered with fog, and this will affect the owner’s attention. Even if you install a rear view camera, but the issue front than the rear to be important. But how can we solve this situation?

Will be fog on the window because the air humidity, dew point temperature when the temperature is below the window, the window will be formed on the surface in the mist, which is what we often see the front windshield fogging. This phenomenon is caused due balance Enthusiasm, so we have to be careful not to let the temperature outside was close to cars.

Concrete can have the following methods:

1 can be combined with outside temperature, according to need to select cooling, heating or ventilation.

2, just open the air supply switch, choose the strongest winds, fog except when required after further reduced. Fog removing the middle to close the outlet when the fog than before to be required to open.

3, If you want to quickly remove the mist, can open the air conditioner, either automatic or manual air conditioning, air conditioner dehumidifier help; but not in the best cold air temperature location, or time defrost, windshield fog outside easily. If a larger vehicle inside and outside temperature and humidity difference, first open the window full ventilation.

4 do not forget to open when needed after the windshield defogging heating wire, heating function along with mirror work while open. Particularly bearing in mind once after the windshield to fog should immediately shut down, the fog is re-opened. After the windshield defogging heating wire is definitely not a long continuous use.

As the rainy season the air is humid, the temperature rise, all kinds of bacteria breeding season, so we must pay particular attention to car cleaning and sterilization of Health. In particular, cushion, carpet, and outlet areas and some dead to pay more attention. Some car owners may not realize the car is too wet will often cause some damage the operation of electronic equipment or lead to unpleasant smell in the car. It is proposed that large owners in the event of wet weather when air conditioners or pay attention to in the car to put some desiccant to moisture.

Women dream car equipment

Some of the woman is called the car jail let the beauty of a woman is the most proud of the carrier. The car, a woman from the doomed man. Then, a woman in the cars should prepare something? Listen to these women, car designers will fantasia surprise?

The most practical and Car GPS system
"Ten women have nine disown road". That seems to be some exaggerated, must have a sense of direction, if not a woman in car equipped with GPS is omitted to find their way to bring trouble and unsafe factors. But the best is still to install a car after a rear view camera, women need to monitor the situation after the car, they want to prevent their husbands.

Second, the clothes rack is the most convenient time
The car is hanging clothes hangers, and fixed in the car, not because of turbulence and wavering vehicles.

Third, the most durable shoes box
As we all know, the woman driving high-heeled shoes, and neither the convenient unsafe. But there are many women special love high-heeled shoes. When driving on shoes, put off until again when the beloved high-heeled shoes on. If there is a shoe box, best can put a few pairs of shoes to attend various occasions wear different shoes.

The loveliest, storage cabinets
Many women have the habit of eating snacks. A bottle of yogurt, two ice cream, and three bars of chocolate makes a woman driving life becomes so full. Men said the woman, but woman greediness, people don't think so, they say in the urban traffic, snacks in emotion, besides can relieve some snacks, still can have hairdressing effect!
Women can have the best car in large storage cabinets, adjustable temperature, storage snacks, Put in the rind such rubbish as, this can be reached to eat delicious, after the rubbish into. Everything is in our hands!

Five, adjustable seat is the most intimate
Women usually sit on a man is delicate and vision for the first window seat and need to adjust seat figure. Current models are back and forth double adjusted design, but most women always want to see that only the front car so safe. Therefore, they hope to adjust seat.

Sixth, the most intimate dressing facilities
Beauty is the nature of man, woman likes more add directors. Every woman's bag will more or less for some cosmetics. We often can see the mirror of woman. The car is not exceptional also, sometimes woman inadvertently from the bag out a small mirror light. Had better have a small box placed cosmetics. Like a man can't literally use a rear view mirror to clothes.

Grasp how to reverse the skills

First of all, see the car before reversing the situation, reversing the route of the well is estimated to determine whether the front will encounter obstacles, reversing try not to step on the gas, control the speed too quickly.

Direction of travel according to the needs of the rear with his left hand turn the steering wheel: If the back right rear needed road, it will turn the steering wheel to the right; the contrary, it will turn the steering wheel to the left. In fact, this and the car moving forward when the shift operation is the same, remember this will not rush the wrong direction.

In reversing the process should not always look at the rear, the car confirm the premise of security, to observe the left and right rear-view mirror from time to time, pay attention to the distance between obstacles and the body, and accordingly used to fix the steering wheel when the body back location. Taking into account the rear-view mirror blind spot about the same time to observe the car in front of the mirror.

If you feel that reversing the process, the front may encounter obstacles, you also need to look at the car at the right time before. Particularly in the steering wheel rotation rate is large enough, because the process of car steering, steering wheel turning radius is greater than the rear wheels of the turning radius, when the car in reverse head thrown outside the range are also great, they must be Note the front to avoid grazing.

Do not cultivate the habit of standing to fight the steering wheel, which is more easily damaged vehicles, and fighting is very trouble. Proposal to install a parking sensor kit, it can always remind and show the distance between rear obstacle condition.

No lamp of safe driving four skills

In the city by car, in general, street lamps, no problem. However, very few lights with no lights or driving on the road, really tired, can take the following remedies:

First, use high beams when driving in the vehicle to use nearly 100 meters before the intersection of light, after the re-use high beam. At the same time, equipped with rear view camera, they should at any time is turned on, preferably also has night vision capabilities.

Second, the general roads are marked with yellow or white lane line, more attention when driving at night in front of the lane to see, this would be easier.

Third, will the vehicles, not to ignore the opposite to car, you still see your lane in front, as long as the traffic in his lane on the appropriate reduction on the line? Car drivers would normally be open beam lights, will not be dazzling, of course, there are some newcomers do not understand high and low beam lights to use, has been there with the high beams, and some unreasonable drivers also been using the high beam, it can only further slow down so he passed. You just pay attention to road conditions in front of the right can, and do not worry.

4, rainy day is too much trouble on the road will be reflective rain, not see the lane. Then it is best with the car running, open beam in front of traffic lights follow the more relaxed, not too far away from the car. If there are no cars with only a little slower car, and always have some people over to the good driving skills in front of you, then they can with the car. In addition, general rain in the night the road is gray and black, bump, bogs; potholes are black, white water office.

Essential characteristics of automotive entertainment marketing

Entertainment Master Michael had mentioned the question and answer this question: "In this time of so few consumers, taste is so fickle world, companies should be how to attract consumers attention? Once to seize the attention of consumers force, what companies can add value to improve the product, make the product more attractive? answer only eight words: "entertainment" or "entertainment factor." that is, entertainment content and experiences. it is not just entertainment, content is also key. Today, the overwhelming economic impact of the entertainment industry, nothing is to. the company must go beyond the competition to please, deeply moved, and consumer education. At present more and more brands to take entertainment to the interpretation of the brand's style, all able to people happy and enjoy the props onto the stage of the enterprise, the only purpose is to interpret the brand, the expression of emotion, to attract consumer groups to achieve the purpose of interaction.

But surging car market, consumers really impressed entertainment marketing, new concepts must include some of the attributes.

Compelling new concept for many reasons, but here are one of the most crucial elements: human nature. Empty and dry, and the concept is clever design of the selling points, after precise positioning, customer analysis have come to realize the concept of people-oriented. With the maturity of automotive consumer psychology, emphasizing cost-effective, automotive safety and rational consumption of individual private cars increased the market demand for the theme.

"Consumer-car entertainment system functional requirements are increasing, they want to enjoy the same in the car dvd, mobile phones, navigation and other emerging consumer electronic terminal. Our mission is to provide them with more cars within the multimedia experience. But in this challenge is how to achieve as much as possible to meet the functional requirements in the premise of maintaining the cost competitiveness of some. "Jong said. Of course, not limited to - "As the home entertainment and mobile market very quickly, consumers enjoy the car entertainment experience requirements also increased."

Safety and comfort aspects. As every year, many people lost their lives because of car accidents, driving on the security presence has been requested to bring this area of automotive electronics demand improved. Car rearview systems such as car import, car parking sensor system installed, all enhanced driving safety index. But the same one question is how to control the entire system cost affordable range. "The safety and comfort, we must balance the two main points: First, improve performance, two control costs."

How to adjust rear view mirror to avoid blind spots

For the past few years, automakers have been offering various detection systems blind spot of the side mirrors of their cars. Often complex, these systems use rear view cameras and reverse sensors to explore the tracks adjacent to the vehicles may have disappeared from view.

The Society of Automotive Engineers (SAE) in 1995 published an article suggesting how external mirrors could be adjusted to eliminate blind spots. The document calls for adjusting the mirror outward until the time the viewing angle side mirrors only matches the rear view mirror of the car. This can be confusing for drivers accustomed to seeing the sides of his vehicle on the side mirrors. But when the right position, the mirrors deny the car's blind spots. This obviates the need to look over your shoulder to change lanes safely and the need for a costly system of blind spot warning.

The only problem is getting used to SAE recommended mirror positions. rearview mirror of the car is used to keep an eye on what comes from behind, while the exterior mirrors reflect the area outside the view of the rearview mirror.

Those who have opted for the approach of the SAE trust him, however, some drivers can not adjust to not use the door mirrors to see directly behind the car and lose his own car to see the side mirrors. To them we say, "Have fun filling out accident reports."

Parking sensor Why is it important?

Parking sensors are an important accession carry. It works the same way and are usually begin in the media bonanza or an agent, although of course the names altered. Most admired bodies whether to accept parking sensors that are available. Help refrain Most accidents adjacent altar by audition and have different variations and designs for them. The precision is accepting a sensor in your agency is one of the smartest things that a being can do.

Instead of hearing beeps, LCD screens and awning of the article as it expands Afterpiece. And trigger anxiety, sensors determine the altar may be too adjacent to his agent. Use liquid crystal display (LCD) reading to determine the scope of an article, such as those used by Toyota and the article, lexus, some parking sensors. Accidents are a complex known alarming to anyone, and this is the accent of the area parking sensors juegoAsí enters advantageous authorized parking spaces linked, anxiety gets stronger depending on how adjacent the article.

Anyone who has an agent must be the acceptance of the parking sensors installed. Some scams use and give you the low range of items, which can even access the risk of causing a stroke. And it can be very beneficial in acclimating bad as well, this is abnormal about those who have eyes bound. Alienated accident, which has no food to absorb or lose much of its aggregation abominable allowance when they will not pay for the accident to your agent. But make sure you get them from a trusted architect. Parking sensors can help save money.

Then there is the electromagnetic sensor, which generates an electromagnetic surface to identify the obstacles to your agent. They are placed in the rear bumper of his old agent. What consequences of tonnage uses the scope of the article to your car, there are also accelerated the parking sensor. Backup Sensor types also vary. The most widely accepted is the parking sensor front and rear. There are electromagnetic sensors that are accessible, that does not put holes in your agent. Make sure you accept the right for you. They are innocently installed on your car equipment room, thus avoiding an accident accessory.

In fact, studies have shown that the sensor is accepted, your agent absolutely reduce the advance of the acceptance of a coup. Are you on your path, or a disguised form, the article, any advance warning you of a car for admission. You can be sure they are appropriate whenever hit the road. Safety is a history of Cardinal when sensors are installed in an agent. Parking sensors are best learned when you want to be sure about safety precautions. There is progress and feel more confident when active the streets. So the affairs of a sensor is the recognition of its purpose, worries, if you want to be active and safe fun at the same time. For this is the absolute tool to help you stay out of the turmoil, not to buy an alternative. Just make sure you get it from a reliable history. But if there is adequate compliance with yourself, a power can help yourself included, can be installed for you. Parking sensors are also less expensive than the parking cameras, and ensure that your bigger car.

Car rear view mirror to make overtaking safer turning

Mirror is active safety device, overtaking, turning back when the car is used to observe the situation, the image of the driver known as "eyes." However, when used as rear view mirror is too much trouble, often in misoperation. How can the proper use of car rear view mirror? Experts made the following recommendations:

First, equipment: a general model of the car is rear-view mirror are flat or single curvature of the convex mirror, generally less than the width of view, there are blind spots for traffic safety. According to statistics, due to traffic accidents caused by blind spot mirror about 30% in China, the United States accounted for about 20% and 70% of highway traffic lane change occurs is due to blind spot mirrors produced. To this end, the traffic control department suggested that the vehicle owner on the more than 8 tons of large goods vehicles on the right mirror for safety modifications, install the "combination of multi-angle rear view mirror" or "multi-vision mirror surface large", to improve vehicle safety and technical performance.

Second, use: car driving, road traffic is always in a dynamic change process. Driver in the observation, collection of traffic information, sometimes just noticed the traffic situation in front of, without attention to the sides and back of the case. In the absence of the correct use of mirrors observation error estimates are often made to take the wrong action measures. Light vehicles are affecting the normal traffic, in serious cases lead to traffic accidents. Therefore, the driving need to pay attention to the following: Adjust the rear-view mirror before driving position and angle. Traffic, due to the vehicle vibration, easy to cause rear-view mirror position and angle, which should be observed and timely adjustment. Some older drivers suggested that the angle rear view mirror to see the rear door handle is appropriate.

In general road parking, starting, overtaking, turning, turning around so driving route will be changed, first give the corresponding traffic signal at the same time we must observe rearview mirror, rear light of experience to judge the speed and then take measures to prevent when a sudden surprise.

Through the market, traffic intersections and other places where people are more to slow the road, to observe the rear parking mirror, and maintain the necessary non-motor vehicles or pedestrians, the horizontal spacing. Up truck in the highway, not only the necessary attention and keeping a safe distance, but also through the rearview mirror observation, determine the following distance behind the vehicle, be aware of when dealing with the situation in order to avoid rear-end accident. Through the intersection when the traffic conflict more, to reduce speed, observe the situation on both sides of pedestrians and vehicles, under the premise of ensuring the security pass. In the predictable braking before the car rear-view mirror to observe, pay attention to the back of the vehicle position and relative speed, brake and then decided to take measures to prevent the brake when the rear-end collision.

A Peak Into the History of Projectors

Projector has been since the mid-1600s, the use. History is not clear who could have been the actual inventor of the projector. A highly educated Jesuit scholar, Athansius Kircher description and instructions to reflect sunlight from the mirror device, through the lens and screen, he was known as the magic lantern. In recording his thoughts, he credited with the invention. These days look like a magic lamp and kerosene as fuel slide. The slide is large and bulky items, some of which pulleys and winches animated version of the production of crude oil.

Michael Faraday in the 19th century burning of oxygen, hydrogen flame heating, and gave a brilliant lime block. This caused concern and 'pushy' lot was born. Near the main source of lighting, domestic all the lanterns. To the remarkable 19th century technology is advanced enough to try hand at the theater. It is so powerful, it gives the look of high noon. Lens and filters are used to create the effect. Striking is the standard projection of light until the late 1800s, when the electric lighting system arrived.

Projector technology improved the same time. This is the entry 'little better' with. It is the dawn of the computer and projector to be stored. With the new business practices of the 20th century, the day after 50 years call. A projection is small, easy to use, reliable, and create clear images of any size can be bright in any room in any light. The call is answered multimedia projector. Principles apply to digital projectors and digital light processing (DLP) was born. In the House before the better known and rising to the challenge of projector manufacturers.

In 1996, SVGA projector using DLP technology, the production of digital images accurately with the development of high brightness. This is the incorporation of built-in sound system. This produced a modern LCD projector. Projectors have become increasingly sophisticated and more expensive. An LCD projector the basic design is frequently used by the amateurs who build their own DIY projection system. LCD projector success, because this is to improve the contrast reached the level of DLP in addition to the dynamic iris back in 2004-05.

In the latest mini projector to ease travel salesman medium-sized projector. Another development is the laser projector. Laser projection technology means that the focus of prediction. This means that there is no need to fiddle with the focus wheel get a picture. There is no need to re-adjust each projector moves closer to or away from the screen. This can focus the laser on uneven surfaces projector. You can easily projected onto the surface areas and other. Projector is the smallest laser projector. They fit in your pocket with your cell phone. Like Aiptek V10 is one of today's best products.
