Automobile Active Security Systems

Security design taken for the prevention of car accidents and to avoid people being injured is called active security design, such as the ABS, EBD, and TCS are active auto security system designs. They are characterized by aiming to improving stability under transport condition of automobiles, making every effort to prevent the occurrence of traffic accidents. Besides, high-mount stop lamp, front and rear fog lamps, rear fog lamps are also active auto security system design.

ABS (Anti-lock Braking System)

It detects the rotational speed of the wheels through the sensor, calculates wheel slip rate by the computer, judges if the wheels lock, orders actuators to adjust brake pressure, and keep wheels in ideal braking mode (almost lock but not a totally lock). Correct understanding of the ABS function: it can maintain vehicles not lock and out of control under the situations of emergency braking. It will maintain steering capability of vehicles and avoid obstructions. Under normal conditions, it cannot shorten the braking distance.

EBD (Electronic Brake Force Distribution System)

It must be used with ABS. In the moment of automobile braking, it will response and calculate each of the different grounds attached to four wheels, and get the friction values. Then it will distribute the corresponding braking force according to every wheel friction values to avoid slipping, tilting and rollover risk due to different wheel brake forces.

TCS (Traction Control System)

When vehicles brake on smooth road, the wheels will slip, or even be out of control. Similarly, when vehicles start or rapidly accelerate, the driving wheels may slip, too. On ice or other smooth roads they will even be out of control and be in danger. TCS was designed for this issue. It relies on electronic sensors to detect the time when the driven wheels' speed falls below the driving wheels' (this is the characteristic of a slip). At that time, it will send a signal, adjust the ignition time, reduce valve opening, reduce the accelerator, change the gear down or brake the wheels so that the wheels will stop slip. TCS can improve vehicles’ stability and avoid the danger of over acceleration as well as drift to out of control.

EBA (Emergency Brake Assist System)

The computer detects the braking action according to the brake pedal to judge the intent of the driver for the brake. If it is an emergency brake, it will order the braking system to generate higher oil pressure making ABS work so that it can make faster braking force and shorten the braking distance.

How to Clean Your Lens Properly

Checking your lens for dust and smudges is something you should do on a regular basis, not only to ensure you’re getting the sharpest possible pictures, but also because a fingerprint or alien smudge left to “ripen” can cause permanent damage to the lens coatings. Keeping your lenses clean isn’t rocket science, but nonetheless, is a chore that should be performed carefully, thoughtfully and with the proper tools and techniques.

Dust and smudges on the front element of your lens (or your filter) are the easiest to spot because they’re front and center. While dust and smudges on the front element can diminish sharpness and contrast levels, you lose greater levels of sharpness and contrast when you have dust or smudges on the rear lens element because that’s the one that ultimately projects your image onto the camera’s sensor (or film). If your “projector lens” isn’t clean, your pictures won’t be sharp as they can be.

The Proper Tools for Cleaning Lenses and Filters Air blower Camel-hair brush Lens tissue or micro-fiber cloth Anti fog lens cleaner

Alcohol or lens-cleaning fluid should never be applied directly onto the lens surface. Doing so can possibly harm the lens coatings and/or compromise the adhesives that hold the lens elements in place. Drop a little lens cleaning fluid on the swab paper (be careful not to drop directly onto the lens), repeating wipe the lens with special tissue paper, and then wipe the lens with a clean cotton cloth until the lens is dry up. There is a coating film on the lens surface. If you use the lens cleaning fluids often, the film will be washed away and affect optical imaging effect. Be careful not to drop the lens cleaner directly onto the lens.

Tips for Cleaning Lens (provided by cleaner manufacturer): 1. Do not wipe the lens often Some people like to wipe lens often even there is just a fingerprint. However, the lens is always worse after times of wipes. Actually the fingerprint, dust, or water stains on the surface of lens is not big problem, just prevent the sunlight on the lens. The lens coating would be black and have scratches. 2. Every time cleaning should be less than 30 seconds We suggest that every time cleaning should be less than 30 seconds because long time wiping could cause unnecessary damage. 3. Use UV filter or lens hood After using camera, remember to put on lens cover or install UV filter and put camera into bags. During shooting pay attention that do not leave fingerprint on lens.

Popular Plastic – PE and BOPP

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a “sheet”. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces. Plastic films are used in a wide variety of applications. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.



Materials Almost all plastics can be formed into a thin film. Some of the primary ones are: Polyethylene – The most common plastic film is made of one of the varieties of polyethylene; Low-density polyethylene, Medium-density polyethylene, High-density polyethylene, and linear low-density polyethylene. Polypropylene – Polypropylene can be made a cast film, biaxially oriented film (BOPP), or as a uniaxially oriented film. Polyester – BoPET is a biaxially oriented polyester film Nylon Polyvinyl chloride – film can be with or without a Plasticizer A variety of Bioplastics and Biodegradable plastics are available.

Polyethylene (abbreviated PE) or polythene (IUPAC name polyethene or poly (methylene)) is the most common plastic. The annual production is approximately 80 million metric tons. Its primary use is within packaging (plastic bag, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4) nH2. Thus PE is usually a mixture of similar organic compounds that differ in terms of the value of n. PE film manufacturer said that, one of the main problems of polyethelyne is that without special treatment it is not readily biodegradable, and thus accumulates. In Japan getting rid of plastics in an environmentally friendly way was the major problem discussed until the Fukushima disaster in 2011. It was listed as a $90 billion market for solutions. Since 2008 Japan has rapidly increased the recycling of plastics, but still has a large rate of plastic wrapping which goes to waste.

Biaxially-Oriented Polypropylene (BOPP) films have become a popular high growth film on the world market because of a unique combination of properties such as better shrinkage, stiffness, transparency, sealability, twist retention and barrier (said by BOPP film manufacturer).

BOPP film is used in a variety of applications including: flexible packaging, pressure sensitive tape, printing and lamination, stationary, metallising, flower sleeves, and cable wrap and insulation. Based on a special molecular structure and stabilisation of the resin, these homopolymers provide optimal mechanical and optical properties, as well as excellent processability.

The Performance & Development of Mini Fridge

Mini Refrigerator Cooling Effect

Mini fridge is usually applied to a small space in which ordinary refrigerator cannot be placed, such as an office or college dorm. "Consumer Reports" (CR) evaluation found models in uneven temperature performance and energy efficiency performance, some cooling effect of the product is less than satisfactory. Some models use cost almost the same as an ordinary freezer refrigerator. The concerned unstable temperature - the different temperature will affect the mini fridge. For the two-door model, the performance of its refrigerated part is very bad, very unstable for most single-door models, frozen and refrigerated temperature. Vertical minibar fridge - if you only need to refrigerated beverages and the packaged meals, then you can choose a vertical Minibar fridge, but such models are not included in the evaluation form.



Swiss Report: Hotel Refrigerator Power Consumption

Said a survey report released by the Swiss Federal Energy Office that, the power consumption of 5.05 million units Hotel Small fridge Switzerland four-star and five-star hotel room is very huge! Its annual electricity consumption is available for 6000 Swiss families a year. The Bureau of Energy, published on the website about attention to the product when a small refrigerator for hotel performance information reference, the proposed hotel to update the small refrigerator energy efficiency levels. The survey reported that the existing 40-liter small refrigerator upscale hotel in Switzerland the average daily consumption is 0.9 degrees (kWh), while the Swiss domestic refrigerators 150 liters average daily power consumption of 0.24 degrees. Swiss Hotel replaces all the existing small refrigerators into energy-saving refrigerators, and the power consumption reduced by half. Swiss Federal Energy Office recommended the hotel to buy a small refrigerator, comparison of different products, energy-saving targets, calculate the cost of small refrigerators use 10 years, try to choose a small capacity refrigerators, and give up the increase in the energy consumption of refrigerators configuration. The Energy Board also recommended to consider placing a small refrigerator allowed behind ventilating, turn off the refrigerator at the reception the off-season, do not store food without refrigeration.

Hotel Mini Refrigerator is in the Changing Process

Room refrigerator works by using the absorption refrigeration way, now the mainstream hotel in the world, all rooms refrigerator are such absorption-class products. The scale, production capacity and brand of WELLWAY company's products in China are the first one. Room refrigerator is in a time of change in the current process, the future development of the two directions are: one is room refrigerator needs and requirements are energy-efficient, green products, so the outlook on energy saving is in this direction, and the second direction requires intelligent, the current refrigerators in the rooms in some developed countries of Europe and the United States, including Japan and South Korea have been more intelligent product updates.
