1 Introduction As people’s living standards improved, rechargeable batteries, especially large current batteries (lead-acid batteries, nickel cadmium and nickel-metal hydride battery) in the power sector, railways, the military has achieved an increasing number of applications, however, battery can be No reliable electricity, and achieve the required plant life, with the battery charge-discharge routine maintenance and management correct or not is closely related. As is now widely used batteries are not with intelligent detection devices, that is, digital batteries, so Hp 530 battery charge and discharge current size, the size of the terminal voltage, charge and discharge time, charge and discharge frequency, charge-discharge capacity, remaining capacity, battery internal temperature and life and other basic parameters, can only rely on manual measurements or roughly estimated that the event of errors, will be our normal production and lives of unpredictable consequences, as well as the electrical performance and life of battery and causing irreparable damage.
With the development of microprocessor technology, mobile electronic devices function on its own in terms of developing very fast, at present the vast majority of digital, intelligent, internal control circuit more or less completed by the CPU chip. But it is part of the power supply is extremely primitive, under normal circumstances is only one battery of the DC to the electronic equipment, while the battery’s own characteristics, status and other parameters are unable to provide electronic devices that can not be related to the electronic equipment data communications. This intelligent electronic devices increase, bringing new problems.
If the battery of various state parameters can be stored by the microprocessor, recording, analysis, control, printing and display, intuitive to provide to the relevant personnel, and to achieve and related electronic equipment for data communications, that is, digital technology, which not only can to reduce human error and extend battery life, but also be able to achieve related to intelligent control and electronic equipment unattended. Therefore, the battery of digital research and development is a significant issue.
2 The concept of digital batteries
The exact definition of the digital battery is still not harmonized. This concept comes from the rapid development of information industry, which mainly come from the world’s leading notebook computer design, production and suppliers. In practice, once the battery is dead when the key is bound to produce unpredictable losses, digital camera batteries idea is put forward in this case, with it, we will be able to grasp the battery status of work on the can be prepared in advance and timely replacement. The working conditions are talking about here should include the following aspects:
(1) the current size of the battery terminal voltage, charge and discharge current size, charge and discharge time;
(2) Current battery impedance, remaining capacity, the remaining charge and discharge time, the battery temperature;
(3) the current battery charge and discharge times, life.
In the actual development, the researchers found that only about the work of the battery status and does not meet our battery requirements, also need batteries to electronic devices and related data transmission, in order to achieve the battery switch, automatic battery charging and so on.
Clear from the foregoing: the so-called digital battery, which contains an ordinary rechargeable batteries, a digital battery control module, as well as the communication interface, complete the battery of the digital measurement and control management and data communication capabilities. In addition to the above-mentioned working conditions in digital form accurate visual display (or provide), but also to provide background information and identity of the battery data (such as battery manufacture date, manufacturer data, etc.); in the process of charging with the corresponding alarm protection measures (such as over-voltage protection, over-temperature alarm, etc.); same time, it should be consistent with some kind of communication protocols (such as system management bus, SMBus), has the host, intelligent charge controller such as communications interfaces, capable of information transmission and control. Schematic diagram of digital batteries are as follows:
Schematic diagram of the digital battery
3 Digital value of the battery status and development
Digital battery first started to develop from abroad. As early as 1995, the U.S. military have been digitized battery equipped troops, but these batteries are not highly digitized, versatility is not strong. According to online information-gathering that is limited, and foreign research and development of digital batteries by rechargeable batteries, control modules, of which control module of the software components should be consistent with the specific communication protocol. Posed by the digital battery digital battery system hardware includes: System console, digital battery (which can be one, it can be a number of pieces), intelligent charge controllers, AC / DC converter and transmit data bus network. Software, including the transmission of data communication protocols, data processing platforms and embedded operating system and the corresponding procedures. There are many foreign companies and enterprises to participate in research and development of digital battery, Intel Corporation and co-production of digital Duracell batteries, this product called PowerSmart, in line with SBS (Smart Battery System) standard. Motorola is also developing be broad user acceptance of digital batteries. Germany’s giant Varta batteries and Duracell companies are developing a new generation of digital batteries, this battery will soon be available.
From the battery industry in the tenth Five-Year Plan was informed that the United States, Japan and Europe accounted for 70% of the global battery market. Consumption of the battery, the United States per capita reached 25 / person; Japan’s annual per capita reached 20 / person. While China’s annual per capita consumption of less than 7 cells. Therefore, the battery in China, a great market. China’s battery industry focused on the mercury-free alkaline manganese batteries, Ni-MH power batteries, lithium-ion batteries, sealed maintenance-free lead-acid batteries, vehicle power batteries, fuel cells, solar cells in the development and production. In the army, the secondary battery, such as cadmium, nickel, nickel-hydrogen battery in a large number of equipment use, military research and development of lithium-ion batteries are also soon will be equipped with troops in the next period of time, there will be three kinds of batteries coexistence phenomenon.Therefore, secondary batteries in our digital, has great space for development. Meanwhile, the secondary battery digitized, people using battery-powered digital time, and will not in the normal work of a sudden power- down and affecting their work and a certain amount of loss; can be more scientific and reasonable or that the use of batteries, the battery will not be over-discharge and over-charge, can effectively extend Canon FS21 battery life; accurately display battery data and provide data to the host can be an effective state of the battery each corresponding control and processing; on the battery aging will also be the final warning prompt ; Therefore, the corresponding cells have a breaking capacity of Jane; constitutes a digital cell system can be used to remotely monitor the battery and the use of reliable data for efficient energy management. Thus, digital battery also has a high application value.

No doubt about the fact that there has been a very remarkable growth in the technology and the infrastructure and this has given birth to a lot of new and innovative techniques. One very important one is the measuring wheels. It has not only simplified the process of measurement but also hassle free. On the basic of the functioning there is some difference between measuring wheels and tapes. Using a measuring wheel ensures you easy access to larger measurements. You can measure any distance with the help of these wheels. Using them do not restrict you in any way like in the case of the traditional tapes where you cannot measure after a certain length, but these wheels can measure lengths up to 9999m in one go.

This is the reason why measuring wheels are preferred for measuring the long distances, because they do not restrict you by putting a length limit. This contributes a lot to the popularity of these wheels. They have been designed in such an artistic way that they tend to simplify even the difficult measurements. The curved, horizontal and vertical surfaces can be measured within minutes without any difficulty. The wheels are the best option for the purpose of distance measuring. This is the main reason that differentiates the wheels form the other measuring equipments including the traditional tapes. What adds on is the point that these wheels saves lot of time and energy.

Measuring wheels are best used while distribution systems are set; line and main extensions are done. They are used better for measuring underground lines, manhole locations, inventories and roads. In fact these wheels are perfectly used for various professional works. As measuring wheels are used rough their making is done meticulously for durability. Manufacturers use aluminum chassis in making them so that they can be used in all weathers. Use of flat rubber tires in measuring wheels keep them perfect in the measurement. Wheels don’t slip easily and measurement outcome comes perfect.

It is very important for the manufacturers of the measuring wheels to keep in mind the use and treatment of such wheels. To ensure a better lock system of the wheels special spring operated trigger release plumber brakes are used so that they could be locked when stored at a place. Usually these wheels are preferred by the people associated with real estate, land measuring, road construction, laying cables, making line of playground and other such purposes, in short for all the big projects. The professional use of these wheels has increased the overall demand of the wheels. When it comes to the robust measuring nothing can beat the wheels. This is one reason why all the measuring wheels are so well equipped and have the stand and brake.

In the recent times the tape measures have become the most important content of the houses and offices, and the credit goes to the unique features that it has. The rules of flexibility have been followed while making these wheels. Their multi – tasking nature has made them very popular everywhere. They could be used for major as well as minor assignments. The process of measuring has been made very simple with the help of these wheels. Tape measures are used to measure specific length. When you have to measure the bigger lengths with repeated use from point of counting then nothing could be better than these wheels. For the larger measurements all that you need is the measuring wheels.

No doubt primary use of tape measures was in tailoring or dressmaking only but there has occurred drastic transformation for measurement purpose today. Tape measures are preferred for lots of measurements now. They are designed in various categories for specific uses. Modern tape measures have added spring facility that makes them easy to handle while measuring items. Although these features are in use for decades but that level of sophistication was not common earlier.

The process of making of tape measures has undergone a tremendous development. In today’s time there are so many modifications that are done in the tapes and that has resulted to the digitized taps with the help of integrated circuits. These features were missing in the traditional tape measures. The qualities of the things have increased with the digitized measuring system. Usually they have a digital screen where the measurement is easily seen. The multiple format display option is what comes next. This has increased the efficiency of the measurements. The use of laser and ultrasonic technology has given a perfect long distance measuring and this has added a lot to the technology.

Appropriate uses of the tape measures make them hold a better position among all the competitors. It ensures safety while measuring the items. These tapes can be extended from particular point to the other with exact placing of end-clip at a fixed point from which measurement is done since initial point. Usually there are specific clips attached to the tape measures at particular point in measurements. These days the tape measures with the steel blade are very common. There is special tension control brakes particularly attached and this facilitates the measurement without an extra effort. All these features contribute in making the tape measures one of the most preferred item in the household.

The dictionary defines telemetry as highly automated communications process by which measurements are made and other data collected at remote, inaccessible or dangerous places and transmitted to receiving equipment for display, monitoring, and recording. The original telemetry systems were termed “supervisory” because they were used to monitor electric power distribution. Telemetry solutions were first implemented in Chicago in 1912, in which telephone lines were used for data transmission on the operation of a number of electric-power stations to a central monitoring command center.

With advancements in technology, telemetry has spread its wings to other fields, each making improvements and modifications to suit the desired purpose. Originally, the data was relayed over wires, but modern telemetry more commonly uses radio transmission and GSM (Global System for Mobile communication) technology for information transmission. One of the limitations of the earlier telemetry systems was the restriction of the subject to the confines of telephone lines. Wireless networking without the encumbrance and restriction of wires connecting the transmitter and receiver has catapulted the potential applications of telemetry solutions.

The list of applications of telemetry is practically endless. Implementing telemetry solutions enables automatic monitoring of large, complex systems such as satellites, chemical plants, oilrigs, and electric power plants, thus eliminating the need for a person to read monitor each location manually. Other areas where telemetry solutions are put into practice include gathering meteorological data, remote meter reading, logistics management, tracking endangered land and marine species, and monitoring manned and unmanned space flights.

Biomedical telemetry or biotelemetry is another telemetry application, which provides a means for transmitting physiological or biological information from one site to another for data collection. Technically, it refers to systems, which require no mechanical connection. Biotelemetry studies in the last three decades have permitted many areas of physiological and behavioral monitoring in diverse conditions. Since the 1970s, telemetry solutions have been utilized for real time physiological monitoring state of patients, who are at risk of abnormal heart activity. These patients are outfitted with specialized telemetry devices, which wirelessly transmit alert messages or distress signals via the standard SMS (short messaging system) protocol to the central database, immediately summoning health care professionals, if the patient suffers from a critical condition.

Science has really come a long way in many areas with the use of telemetry equipment. Even many of the small towns use telemetry to read the electric meter from the truck as it drives by your house. It has become more cost effective to use telemetry in reading the electric meter as opposed to having a person walk from house to house recording the readings in a hand held device.

Kids give you tough time especially when they are not feeling well. Also they start throwing tantrums when you start coaxing them to behave in a particular manner because you have to measure their fever and this is a daunting task. More so when you are using an old thermometer that had to be tugged below their armpits in order to get a perfect reading. You had to hold your child still so that the thermometer did not slip from its position. You might have also broken the thermometer in the process and as a result your child might have got hurt.

But there is a way out. In an era where technology has made our lives far easier, we can always search for innovations that are easy to use and far better developed, in terms of safety. The baby digital thermometer does not require you to force your child to stay in a particular position and you can just hold it against the forehead to get a reading. Unlike glass thermometer where you find it hard to make out the exact temperature, here the LED screen will flash the recorded temperature instantly.

The technology also allows you to view the last recorded temperature in case you have lost track of it. The tip of this object is replaceable and so if you fear contamination or damage you can get it changed. Also unlike the glass one a baby digital thermometer lets out a beep after completion of each process making us realize when a process has started and when it has ended.

Also a baby digital thermometer is not a rare object. Nearly every digital store has them, so you are not required to spend time searching for it. They come in attractive colors. Moreover these thermometers are not pricey objects so you don’t have to worry about the expenses. There is another variant of the baby digital thermometer and is known as the infrared thermometer. You can take temperature from a distance and there is no need to make them come in contact with the patient’s body. The prices of the latest variants are somewhat steep.

There are several online stores from which you can get one of these and get it delivered at your doorstep. With this product you are not required to hold you child stiff or force it in the mouth to measure fever, and so this product is a much safer and convenient alternative.

Tape measures are used to measure short distances. The tape measures have also undergone its share of advancement and today we get them in the form of digital tape measures. The digital tape measures are very accurate and easy to use. They have a digital screen where the result is displayed. Depending on the type of the surface you want to measure, tape measures are found in many types. The tape measures that are available in the markets are very accurate and the price depends on the number of features this tool has in it.

The traditional tape measures where the tape had to be wound again after used has been replaced  by the modern retractable form. Here we do not have to roll the tape inside the case after use. The tape is retracted automatically inside the case with the help of a small spring that is attached to it. The spring if damaged in this case has to be replaced for proper functioning of the measuring tape. These retractable measuring tapes have to be used gently.

If you are using a steel or metal measuring tape then you have to be extra cautious with it. With the prevalent weather conditions the metal inside the measuring tape expands and contracts. This expansion and contraction can have a great deal of effect on the measurements. To overcome this situation you can use the digital measuring tape which gives accurate results under all weather conditions.

While measuring surfaces the least count of the measuring device is very important to get the most accurate readings.  While taking the measurement human error is also likely. You have to keep records either by marking or by noting down the measurements so that the factor of human error can be avoided. In today’s date the laser measure is considered to be the latest and the best in the measuring technology. The laser measure uses laser beams to measure surfaces.

The laser measures use the combination of both laser and digital technologies.  Combination of these two technologies work together to yield the most accurate results in measurement domain. In older days measuring surfaces using traditional measuring tapes used to be very inconvenient as the tape used to sag after some years of using . But now with the new tapes this drawback has been overcome and measurement can be taken just by pointing the laser measure.

The laser measures have a digital screen where the calculated distance is displayed. For long distance measurement the measuring wheel is used. The measuring wheel looks like a walking stick with a wheel attached at the base. Some of the measuring wheels have a digital counter also. This tool is very accurate and long distance calculation is done very easily with it.  The cost of the laser measure is higher than the digital or the traditional measuring wheel. So cost wise measuring wheels are preferred over laser measures.

If you want to buy a good brand of measuring wheels, they you may want to go for the Dura Wheel measuring wheels. Almost all leading measuring tool stores stock these measuring wheels. The Dura Wheel measuring wheels are so designed that it can be used in rough conditions and rugged terrains. This is for the reason that when the surface is undulating most of the measuring tools fail to give the correct measurements. Storage of the measuring tools when not in use is an important factor. If not stored properly the tool may lose the accuracy of measurement as some tools made of metal tend to expand or contract under different weather conditions.

The Dura Wheel measuring wheels are available with the carrying case. This is to ensure that after packing, the Dura Wheel measuring wheels are safely kept. The Dura Wheel measuring wheels are durable and last for a long time without much maintenance. The Dura Wheel measuring wheels are available with the following features:

o    Folding handle with hefty pistol grip

o    Hi-traction tire

o    Sealed roller bearings

o    Balanced in-line design

o    Belt driven counter for long life and smooth operation

The tape measure has evolved into a much modern process of getting measurements. It developed from the ribbon type to the most modern digital and laser technology capable of measuring in the most accurate method.

Tape measures are similar to rulers but, the difference is that it can be folded or rolled. They are commonly used for dressmaking and tailoring. They are made up of ribbon, cloth, plastic, or metal. Tape measures consist of linear measure marking in metric and imperial units. Carpenters or construction workers also make use of tape measures made up of thin metallic ribbon that remains straight. The metallic ribbon retracts into a small convenient storage. Surveyors also utilize tape measures with a hectometer as its measuring unit.

A unique feature prevalent to most tape measures is a small diamond which is embedded every 19.2 inches. It is called black truss marking. Measuring tapes are ideal measuring tools because of its flexibility which can be used to measure even tight corners and curves. It can also be carried in a pocket because of its small size.

This measuring tool comes in different types:

Body Measuring Tape

This type of measuring tape can be used to measure circumference of the head, waist, legs and arms of the body. One of the models of this type is the Quick Medical QM2000 Measure Mate Body. It features accurate and quick measurements. Another good feature of this tool is that it can measure up to 60 inches and has automatic retracting system. In addition, measurement readings are shown on both sides of the tape. For a more accurate measurement, a 0.1 cm increment is used with this tool.

Measuring with the Measure Mate is simple. Just wrap the retracting tape around the area which you want to measure and then put the end into position. Afterwards, just push on the button and it automatically locks into position.

Adhesive Measuring Tape

This type of tape measure comes with an adhesive that allows it to be removed and positioned on almost any surface. The tape can be written with marking pens or pencil. It is 1 inch wide and 100 inches long and is colored white with black numeral markings. This is mostly used by police investigators or Scene of the Crime Operatives (SOCO). It is ideal in measuring blood splatter on any surface, bullet holes, or any pieces of evidence for crime scenes.

Magnetic Measuring Tape

The magnetic measuring tape is ideal for measuring metal surfaces. It is made up of vinyl material with a UV resistant red and blue ink. It is one meter long and uses standard and metric measurement system.

Laser Measuring Tape

This type of measuring device is one of the latest advancements in measuring technology. This device can be manipulated to accurately measure length, width, distance, area, and volume. Basically, it is used by interior designers, architects, and craftsmen. The great feature of this device is that it is able to measure hard to reach objects such as buildings and billboards if it is 300 feet in distance.

The TLM100 is one of the models of this kind of measuring tool. With its point and shoot technology, it can measure quickly and precisely without having a need for an assistant. Plus, it lessens the burden of having to calculate a lot of measurements. Some of the latest models include LCD display and Bluetooth technology for fast and easy data transfer.

Digital Measuring Tape

It features an LCD that displays the measurement made. Measurements can be made in inches, feet, and even fraction measurements. The measuring device automatically switches on when the tape is extended. It will turn off when the tape is retracted into its case. The measuring tape operates with the use of two LR44 batteries.

Most of the modern spring tape measures are design based on the patent by Alvin J. Fellows on July 14, 1868. The spring tape measure has existed ever since Fellow’s patent. It was not widely used during that time. But in 1940, it slowly emerged and supplemented in the form of the folding ruler.

Having a proper tool for measuring jobs requiring the most exact measurement is important. The slightest inaccuracy in measurements can cause a big difference and may lead to waste of time and material. This is especially true in woodworking, tailoring, and architecture. To achieve the best results, accuracy is necessary.
