Brake system for automotive safety-critical driving. However, the maintenance of the brake system is often overlooked by the driver. Often until the discovery of the brake system is not working properly when in the best brake system overhaul. This is very likely to lead to brake failure due to unexpected failures lead to disaster. Therefore, only the regular maintenance of the brake system and brake system maintenance to ensure the normal operation, thereby ensuring driving safety. Cars and small trucks brake system is mainly used brake fluid to pass brake force, and large passenger cars and heavy goods vehicles using pneumatic brake system. For different braking systems have different maintenance methods.
Regardless of any brake system, brake pads by the end (disc) or brake shoe (drum) complete the braking effect. Therefore, to regularly check the brake pads or brake shoe thickness. When the thickness is found close to or less than the minimum thickness specified by the manufacturer should be replaced immediately. Check the brake pads at the same time, also check brake disc or brake drum wear, such as timely access to dent the surface of the disc or drum brakes to ensure the contact area with the increased braking force.
For the oil brake the car, check the brake fluid before moving to the surface. Decline in oil is found, to immediately check whether the brake oil leakage areas. Because brake fluid absorbs moisture from the air, a long time will fail. According to the manufacturers require regular replacement of brake fluid. Best replaced once a year.
For pneumatic brake system, exhaust system should pay attention to regular and periodic replacement of water in the dryer. Gas system in the water will affect the corrosion of piping and the braking effect. Can lead to serious or even brake failure. Also, always check the work of fighting pump belt and pump wear. If problems are discovered must be promptly replaced.
Brake replacement cycle
Usually we will be on the dashboard brake warning light is illuminated for brake shoe as the basis to judge, but the bottom line is, if only for this time, is quite dangerous. To remind you that, although all vehicles have this warning system, but some direct sense the thickness of the brake shoe, while others are in the brake shoe has been completely finished grinding, brake fluid so extreme decline, will make warning lights up. If the latter, until the warning light, brake pads and brake discs have been the base metal is iron sharpens iron status, then, will see the bright edge of the tire near the rim of iron cut. Therefore, each time into the plant maintenance can be checked whether the brake pads, and early life of floor near the brake pads replaced, and the warning lights do not just believe.
Routine brake system maintenance
Clean, high-quality brake fluid, power brake system is safe and good basic condition. You should always buy the best quality brake fluid market. If brake fluid is dirty, rinse and let go of the whole system, and then filled with new fluid master cylinder. Do not reuse brake fluid, all from the system to be let go of the brake fluid should be discarded.
Maintenance projects in the brake system, the periodic inspection of the brake surface is the most important. Check at least once a month, more often the better.
Inhalation of asbestos dust is harmful to your health. With a dry brush or compressed air to remove dust and dirt on the brake system will scatter dust, as one can easily contain asbestos fibers, it is easy to damage health. Dust and dirt should be designed in addition to asbestos vacuum cleaner to deal with, and should use dust patterns. If there is no vacuum cleaner, then the maintenance of the brake assembly should be in a well ventilated place, and put through the identification of the virus contained breathing apparatus.
Check the brakes before, carefully wipe the dirt on the master cylinder, so as to avoid any dirt fall into the tank. Remove fasteners (usually pin) and the lid. No scale for the fuel tank, fuel tanks should be kept away from the top surface 6 mm, if the scale, the scale than another job as long as they can surface. If the master cylinder needs fuel, add line DOT3 or 4 brake fluid overload specification.
Careful Do not brake fluid base in paint, because it has a strong corrosive, would destroy the finish.
In a very long period of time if the total lack of brake fluid, and you always add, that it is clear that something wrong with your brakes, you should check the. The color of brake fluid warning. Color of brake fluid should not be too deep, and should not look like burnt. If so, then there is a problem, but this does not happen very often.

Vehicle Autumn Maintenance Analysis
Into the fall, with the weather gradually cooler, many car owners have started to do "beauty detox", after all, after a summer of sun and wind, the windows open for a long time, a lot of dust accumulated inside , playing off the soot on the mat, the horizontal seat surface stains, shoe prints inside the lower side of the door, instrument panel and roof of the dust needs to properly handle it.
Day Traders Auto Sales & Service Co., said sales director for long, his hands to the car owners to "clean", there are many aspects that require attention.
Leather seats
Do not dry with a hair dryer emergency
Currently, the car seat is basically divided into the leather seats and plush seats two. For both seats, the maintenance methods are also different. Owners when their own hands clean leather seats, do not just spray chemical cleaning agents go, you can choose some of the strong alkaline cleaning agents, for example, commonly used in soap and water of life, the amount of soapy water into a soft towel, gently clean, dry air Cawan soap, after the soap-free wet towel and then wipe twice to. Day Traders Auto Sales & Service Co., Ltd. High Long warned: "In this process, it is worth noting that the consumer after cleaning do not use hair dryer to speed drying, the leather can not be exposure, apply a soft towel or tissue paper to avoid scratching the leather, causing leather fracture, the best in the cool air dry naturally. "
Fabric fabric seat disposed relatively simple. Woven velvet seats are not dirty, used a long-haired brush and strong suction vacuum cleaner with one side brush the surface of the seat, while the suction with a vacuum cleaner to suck out the dirt.
Car carpet
Do not scrub completely immersed into the water
The car is most likely dirty carpet, high-Long said that in the automotive carpet cleaning, many consumers are likely to enter errors, cleaning the entire carpet in the full immersion into the water scrub. In fact, such an approach is not desirable, on the one hand, all soaking will destroy the carpet bonding within the layers of different materials, on the other hand, this may cause the car washed, the carpet wet, corrosive chassis.
In fact, for not a dirty carpet, the vacuum cleaner with a brush head for cleaning process can be, if the carpet is dirty, then with detergent to remove dust before work, then spray the right amount of detergent with a brush scrub clean with a clean rag and siphoning off the excess detergent on it, so you can make any connection with both clean and washed before the carpet as soft.
Cleaning the instrument panel
Use anti-static cleaner
For the instrument panel and center console clean, high-Long told reporters, leather seats with center console clean principle similar to the principle of cleaning, cleaning tools you need to use central console with a clean cloth, mild detergent and water , should not wipe with a wet rag. Need to remind consumers that: Select the best type of cleaning agent with anti-static plastic cleaning agents, the effect will be better.
As the instrument panel of the various obstacles plenty of money, owners can prepare a "special tool", with a variety of different film thickness of wood or a ruler, put it into a ramp repair triangular head, different rectangular or tapered styles, and then with a clean cloth bag, simple and effective. You can use the dashboard dashboard wax maintenance.

Summary of types of electrical accidents
Electrical accidents including personal accident and equipment accidents. Personal accident and equipment accidents may lead to secondary accidents, and both may occur simultaneously. Electrical accidents are associated with electrical accidents. From the energy point of view, the electrical power will cause loss of control accidents. According to the form of electrical energy, electrical accidents can be divided into electric shock, lightning accidents, static electricity accident, incident electromagnetic radiation and electrical equipment accidents.
1, electric shock,
Electric shock from the current and its conversion into other forms of energy caused by the accident. Into shock and electric shock accident injuries. Shock is the current directly on the body caused by injury. Electric current injury is converted into heat energy, mechanical energy and other forms of energy in the human body caused by injury. Electric shock accidents often happen suddenly, in a very short period of time causing serious consequences.
Commonly referred to as electric shock refers to the shock. Shock into direct contact and indirect contact electric shock electric shock. The former is the normal state of touching live electrical shock occurs when the charged body, also known as the normal state of shock; reach the normal state which is not charged, but an accident during a fault condition occurs when the body charged live electrical attack, also known as electric shock under fault conditions.
Electric shock into the arc burns, the current burns, skin metal, electric branding, mechanical injury, lightning eye and other injuries. Arc burns are burns caused by the arc discharge, is the most dangerous electric shock. Arc temperature up to 8000 ℃. Can cause a large area, deep burns, and even charred, burned limbs and other parts.
2, lightning accident
Lightning accidents are caused by nature, Chiang Kai-shek, the negatively charged form of energy caused by the accident.
3, electrostatic accident
Accidents are caused by static electricity or process arising from human activities, relatively static positive charge and negative charge in the form of energy caused by the accident.
4, electromagnetic radiation hazards
Electromagnetic radiation is incident radiation energy in the form of electromagnetic waves caused by the accident. Electromagnetic radiation refers to electromagnetic frequencies above 100 kHz transition. In a certain intensity of high frequency electromagnetic radiation under crossing, the damage suffered by the human body mainly as dizziness, memory loss, poor sleep and other symptoms of neurasthenia. In severe cases, in addition to increased symptoms of neurasthenia, but also associated with cardiovascular symptoms. Electromagnetic waves damage the human body there is a lag, and may affect offspring by genetic factors. In addition to harm the human body, the high-frequency electromagnetic transition can cause high-frequency induction discharge and high-frequency interference.
In addition to radio equipment, high-frequency metal heating equipment (such as high-frequency quenching equipment, high-frequency welding equipment), high-frequency dielectric heating equipment (such as high-frequency heat sealing machine, drying equipment, insulation materials), is electromagnetic radiation dangerous equipment.
In order to prevent electromagnetic radiation hazards, should be taken to shield, absorb other special precautions. For high-frequency shielding and protection of the plate with a mesh screen can be copper, aluminum or steel. Necessary, consider double-shielded. If the shield plate coated with tiny particles material, can reduce the reflection of electromagnetic transition. More effectively absorb the energy of electromagnetic waves, constitute the so-called absorption shield.
5, electrical equipment failures and accidents.
Gas system failure caused the accident, including: abnormal power failure, abnormal electric, electrical equipment damage, electrical wire damage and short circuit, disconnection, grounding, electrical fires.
Abnormal power failure in the normal production process, a sudden power interruption. This makes the production process into chaos, resulting in economic losses; in some cases, will result in accidents and casualties.
Abnormal live in normal circumstances should not be charged or which part of the production facilities unexpected live. Easily lead to abnormal persons Battery for CANON BP-808 charged hurt.

The basics of laptop screen
As we all know, the notebook's screen size determines the size of a machine type, weight, and even design. As you heard most of the mainstream of 12.1,14.1 and 15-inch notebook, in which the size of the notebook's size is that screen size, rather than the size of the machine. Largely determines the size of the screen a certain type of machine performance and market position. 12.1 inches mostly 1-Spindle ultra-thin, thin and light machine. 14.1-inch mostly 2-Spindle design notebook. 15-inch All-in basically 3HD or models of.
Laptop LCD screen in a notebook occupies the entire cost of 1 / 3 share or so. Its production process and desktop LCD screen is almost the same, but the power supply module for the notebook's power consumption require special design.
Resolution of the LCD screen is a very important parameter. Now 12.1-inch screen resolution is also achieved XGA (1024 * 768) 14.1-inch LCD screen, full resolution of marching to SXGA, and UVGA and WXGA or 15 inch LCD screen of the world. In the same size LCD screen, higher resolution screen displayed more delicate. So buy a notebook, as far as economic conditions allow selection of high-resolution LCD screen.
In addition to concern for users of LCD resolution, but also know what type of LCD, LCD liquid crystal display usually HPA, DSTN, TFT three. DSTN is STN (super twisted nematic displays) to optimize the development of core technologies over the top, DSTN as dual scan technology, so the display is more delicate than the STN, more bright colors. The early notebook mainly use the LCD STN, DSTN since then the emergence, LCD and gradually switch to a DSTN LCD. STN and DSTN slower reaction time, usually around 300ms. Users can clearly feel the blur, and good at games and video are not now so perverted, so the general office user is acceptable.
As user requirements increase, STN, DSTN LCD gradually can not meet the user, so DSTN LCD manufacturers developed based on the HPA. HPA as fast DSTN, which is an improved DSTN. As the STN improved DSTN is the same. HPA can provide a better reality than DSTN quality, reducing the LCD response time, increase the LCD contrast and viewing angle, as it is DSTN improved over the production line changes very little, so the production costs and DSTN similar in price The above will reflect certain advantages.
Now the production of notebook LCD TFT screen is the most used. Is the thin film transistor TFT is used to actively control the amount of light through each pixel component. We have also called it "active-matrix thin-film transistors."
Color filter is composed of red, green, and blue color filters, a pattern of production in a large glass substrate. Each pixel (point) is a unit composed of three colors. If a panel resolution of 1280X1024, it actually has a 3840X1024 transistors and sub-pixels. ㄧ a 15.1-inch liquid crystal display (resolution 1024x768) the pitch of 0.3mm; and 18.1-inch liquid crystal display (resolution of 1280x1024) The dot pitch is 0.28mm. This also explains why the same size the higher the resolution the LCD, the screen will be more delicate, and brightness, contrast have different losses.
Notebook TFT-LCD brightness values are generally in the 150 ~ 200 cd/m2 (very few can reach 250 cd/m2). Although technically possible to achieve higher brightness, but that does not mean that the higher the better brightness values, because the high brightness of the display may make the viewer eye injury, but also will increase the power consumption of laptop battery use mode less time. Contrast is defined as the maximum brightness value (all white) divided by the minimum brightness value (black) ratio, the greater the ratio, this monitor is better. The LCD should be all black is not easy, but the backlight is always lit, followed by more or less there will be leaked. The human eye can accept a ratio of about 250:1 on.
Now we are increasingly concerned about, LCD response speed. I regret to tell you, because at this stage structural characteristics of the LCD itself, and technology development. Desktop LCD to enhance the reaction rate is the height of the crystal most of the voltage, the power consumption increases. This will reduce laptop battery mode in time. Laptop LCD response rate still at 20 ~ 30ms between. Most of the reaction rate in accordance with this notebook's LCD, or barely able to play CS, a class of games, DVD, or you can look at the
As individual notebook manufacturers have their own unique offerings of LCD technology, so that your notebook's LCD display with different characteristics, such as the notebook's LCD to be bright colors more. The high-end notebook in the ThinkPad FlexView Display170 used above degree viewing angle. Of course, everything can only let buyers choose.

Diagnosis of battery failure
Automotive lead-acid battery capacity will often appear lower self-discharge, excessive consumption of electrolyte and other faults. For these failures, observation can be used to diagnose.
First check the externally. Shell should be no large cracks, no leakage; electrolyte liquid is too low will lead to spillover, but also lead to reduced battery capacity. Surface should be clean, pole for corrosion, the positive lead (FireWire) should be insulated well, or will cause self-discharge phenomenon. There should be no loose joints, grounding should be solid, or increase the output impedance will reduce the output power. Then turn on headlights check. If white light is off, the battery is normal; if dark red, it indicates that power is low.
Then turn the starter. If the starter speed to normal, though slightly dim lighting, but there is still enough light, then a good, charge than the foot; If the starter seems weak, and the light becomes dark, then the battery from over discharge, should be immediately charged; If connected to the starter, the lights dimmed light, and immediately turn off the engine, then the battery discharge has exceeded the limit or plate has a serious curing.
If a fully charged battery with a good first day, over night and then they are using electricity, then the short-circuit the battery or circuits or serious self-discharge phenomenon.
After the initial examination, the electrolyte fluid level should be observed. If necessary, add distilled water. If confirmed the loss of electrolyte, the corresponding density of the electrolyte should be added.
For battery failure, once discovered, should be excluded. casing cracks, leaks, repair should be removed, otherwise it will lead to early battery scrap, but also severe corrosion of other auto parts; save battery power shortage, should be promptly charged; internal self-discharge exist, or vulcanization of the plate severe Batteries should be removed for inspection. If the problem is serious and should test new ones.

Smart Battery Charger Specifications
A smart battery charger is designed to increase battery life. Using a smart battery helps in faster, fuller and safer charging.
The word "smart" in 'smart battery charger' refers to a microprocessor-controlled charger. This microprocessor helps the to perform complex functions such as letting the user know how much battery charge remains and also the health of the battery. Smart Battery Chargers are mostly used in complex electronic and electrical equipments such as computer notebooks, digital cameras, medical related equipment, etc.
It's interesting to note that smart battery chargers are primarily used with smart batteries and not not with those that simply let the charger know when and 'how much' to charge the battery.
Smart Battery Charger uses a Smart Battery
Two important factors related to any are its state of charge (SoC) and state of health (SoH). Wherein normal batteries fail to communicate with a user about their Soc and SoH, a smart battery is able to communicate both with the charger and the user.
There are various categories of smart batteries. The most basic type may include nothing but a microchip that simply sets the charger to charge according to the battery's need. But according to the SBS forums, a smart battery must indicate its SoC correctly to both the charger and the user.
Smart Battery Charger Specifications
A smart battery charger periodically communicates with the Smart it is connected with, and uses an algorithm to set itself to charge the battery in response to the SoC and SoH information provided by the smart battery.
A typical smart battery charger, which is, in fact, controlled by a smart battery, interprets the warning messages sent by the battery in the form of charging voltage and charging current. The charger, in turn, obliges itself to the charging algorithm provided by the smart battery and defines its output according to the needs of the battery.
Smart Battery Charger and Smart Battery Communications
There are various forms of communications that may be performed between a smart and a smart battery charger. The very common ones include the smart battery telling the smart battery charger to set the appropriate charge current and charge voltage, allowing access to the correct charging algorithm for the battery and to allow a speedy charging of the smart battery as safely as possible.
Advantages of a Smart Battery Charger and a Smart Battery
A smart battery charger system is self-aware and communicates all important charging related information to the end user and also to the smart battery charger. A smart battery charger's biggest advantage is that it refrains a smart from getting overcharged. This also helps in conserving power.
Also, a smart battery will inform the end user of any failure or fault in the battery itself or the charging system. This helps in preventing potential failures that may occur otherwise. The punch line in describing the advantage would be that a smart battery charger provides the smart battery with exactly what it needs, when it needs it.
Other advantages of a smart battery charger include faster charging, fuller charging, more usable capacity from battery, smaller chances of over charging and killing sealed batteries. All these factors ultimately lead to a longer smart battery life.
