For over a century, biometrics has been used to identify criminals. Today, this technology is quickly becoming a form of identity verification in non-conventional ways. From mobile banking to smartphone security, society is embracing the need to protect important information.

 

The workplace is no different, with more companies seeking smarter ways to track time and attendance. Recognizing that this area of business operations can impact profits, many are choosing a fingerprinting method.

 

This allows companies to positively identify each employee. Doing so eliminates wasteful practices. Through the technology of biometric timekeeping systems, companies now have a solution that saves time and money.

 

Here, we look at seven benefits that using a fingerprint time attendance system provides. Companies that choose to switch from traditional time tracking processes will soon realize it was worth the investment.

 

  1. Clock-in accuracy is improved.

Fingerprint biometrics is the most reliable personalized way of determining an employee’s identity. No two sets of fingerprints are alike. Employees cannot engage in buddy punching because it is impossible to pretend to be someone else.

 

This clock in system provides a distinctive, measurable characteristic that makes it is impossible for employees to steal time. Passwords can be easily shared or replicated. However, the biometric clock invalidates punches that do not match stored data.

 

Unique biometric identifiers guarantee that employees only clock-in for themselves. This gives managers accurate data for attendance reports. Furthermore, this type of system reduces – and possibly eliminates – costly errors.

 

  1. Internal processes have higher security features.

Businesses that are responsible for securing sensitive data must have solid internal processes. Giving people free access to entering the building is not the best way to ensure data remains safe. Critical information is only as secure as the room in which it is stored.

 

A time clocking in system that requires fingerprint identification keeps secured information secure. As a convenient security solution, employees are not encumbered with badges or remembering passwords.

 

The expense of replacing lost badges and ID cards can eat away company profits. Besides, people may forget passwords, making traditional security methods a nuisance to daily operations.

 

  1. Entry points of a building are secured.

Equally important is making sure all entry points of the building are secure. The added layer of security keeps data and everyone who enters the building safe. This includes visitors who may want to maintain privacy, depending on the type of business.

 

The fingerprint time system ensures employees check-in for them. It also helps to keep unwanted visitors from entering the building on false pretenses. For example, an employee who works at a bank might lose her ID badge. If someone found it, they could enter a secured area of the bank without having to prove they are the person to whom the badge was issued.

 

Biometrics keeps the right people in and the wrong people out. Because of the electronic setup, the system can be placed at every entrance.

 

  1. Fingerprint time clock systems are always available.

Improved synchronization with the Linux operating system makes the latest technology for biometric time clocks consistent. Availability is never in questions because the system uses Dynamic Host Configuration Protocol, or DHCP, for IP addresses.

 

This delivers remote configuration capabilities so employees can use a web browser to clock in and out. Additionally, time and attendance data is never lost. Stored memory allows employees to enter their arrival and departure during a network outage.

 

  1. Fingerprint time clocks can integrate with other business systems.

Integration with business systems that are important to daily operations is an added convenience. Onsite installation is possible to ensure an easy centralized network interface exists. Other clocking systems like desktop models or proximity clocks can merge with a biometric system.

 

HR managers can simplify payroll integration with a faster, more accurate processing system. Biometric time clocks track time and attendance in error-free fashion. Supervisors view and approve electronic timesheets.

 

The interface with outside payroll providers allows supervisors to export the data at the end of every pay period. Automatic calculations ensure the once time-consuming payroll process is completed quickly with up-to-date work hours.

 

  1. Companies can easily expand with a scalable system.

Biometric systems are flexible and easily scalable for companies of every size. If expansion is in the future, this investment grows with it. Whether companies add new locations or more employees at one location, investing in a new system is not necessary. Employees connect to a centralized time tracking system in the office, at home or overseas.

 

  1. An automated workplace functions better with the biometric fingerprint time clock.

Companies are always looking for efficient processes to save on operational and labor costs. Biometric fingerprint time clocks offer these options. Problems with traditional time clock system are eliminated. Employee identification is authenticated at every entry point.

 

Managers no longer deal with inefficiencies of manual time recording. Instead, companies see real returns with smoother timekeeping processes. Manual processing by payroll clerks and employees over-estimating their time are rife with excessive costs.

 

The automated platform that comes with fingerprint time clocks help to decrease labor costs. Less time is spent processing payroll. This essential business task becomes easier to complete while eliminating human errors.

 

Conclusion: Biometric fingerprint time clock and workforce management is the perfect pair.

Companies must consider the benefits of switching from a traditional time tracking method to a fingerprint time clock. Keeping in mind that biometrics has been used effectively in the workplace, it is easy to understand how this technology is beneficial to workforce management.

 

Misconceptions and confusion persists, despite the reputation of biometric systems. Countering facts with concerns helps to make this an easy choice. Biometrics give employers the ability to capture real-time labor data.

 

Using a fingerprint time system delivers a secure, safe and accurate way to keep employee attendance records. The broad range of direct and indirect cost benefits allows companies to see a significant reduction in these costs.

 

Through automated processes and individualized recognition, companies will not lose money or secure data. Employees cannot buddy punch; when they do arrive at work, they can safely enter the building.

Alternatively known as an AC / DC power adaptor, AC converter or charger, an AC adapter is an external power supply used with devices that run on batteries or have no other power source. AC adapters help reduce the size of a laptop computer by alleviating the need for a standard sized power supply. An AC adapter is made up of a central unit which draws power from an AC outlet. It then converts the power to DC that is used by the computer, and a second cord that plugs into the computer.

 

Each AC power adaptor has a specific power rating, measured in volts or watts that it can handle and output to an electronic device. Because of the power rating and the type of plug on the end, an AC power adapter is not universal and can only be used with devices with the same requirements and connector.

 

If necessary, a universal AC power adapter can be used, which is designed to work with many devices, having multiple types and sizes of plugs for connectivity to those devices. A universal AC adapter may also have a voltage or wattage range that it can output, like 100 volts to 240 volts or 70 watts to 125 watts, providing for a greater range of compatible devices.

 

Founded in 1981, Hon-Kwang Electric Co., Ltd. is a company of power supplies and specializing in the design and manufacture for the domestic and foreign market. Hon-Kwang’s main Power Supply products include Power Transformers, AC/ DC Power Adaptors, Charger, Switching Mode Power Supply, LED Power Supplies and etc. If you need more information about power supply series, try to send inquiries or contact with Hon-Kwang directly!

The ceramic capacitor is available in many versions including leaded disc ceramic capacitors, surface mount multilayer ceramic capacitors, MLCCs etc.

 

Ceramic capacitors are one of the most widely used forms of capacitor used in electronics equipment these days.

 

Ceramic capacitors have also been used for many years, being found in valve or tube circuits dating from the 1930s.

 

Today ceramic capacitors area available in a variety of formats ranging from leaded components to surface mount technology, SMT varieties. As leaded versions disc ceramic capacitors are widely available, and as SMT devices, multilayer ceramic capacitors or MLCCs are available in all the common formats. As such these ceramic capacitors are used in virtually every type of electronics equipment.

 

The actual performance of the ceramic capacitors is highly dependent upon the dielectric used. Using modern dielectrics, very high values are available, but it is also necessary to check parameters such as the temperature coefficient and tolerance. Different levels of performance are often governed by the dielectric used, and therefore it is necessary to choose the type of dielectric in the ceramic capacitor.

 

Ceramic capacitors range in value from figures as low as a few Pico farads to around 0.1 microfarads. In view of the wide range and suitability for RF applications they are used for coupling and decoupling applications in particular. Here they are by far the most commonly used type being cheap and reliable and the loss factor is particularly low although this is dependent on the exact dielectric in use.

 

Basics of Ceramic Capacitor

Ceramic capacitors are the workhorses of the capacitor world these days. Ceramic capacitors are used in millions as a result of a combination of their cost and performance. There is a wide variety of dielectrics that can be used as described below, but as the name of the ceramic capacitor suggests, they are all ceramic in nature.

 

In order to ensure that sufficient levels of capacitance can be obtained within a single capacitor package, ceramic capacitors, like types of capacitor have multiple layers. This increases the level of capacitance to enable the required values of capacitance to be achieved.

 

Ceramic capacitors are available now in three main types although other styles are available:

 

  • Leaded disc ceramic capacitors for through hole mounting which are resin coated
  • Surface mount multilayer ceramic capacitors
  • Specialist microwave bare leadless disc ceramic capacitors that are designed to sit in a slot in the PCB and are soldered in place

 

Although it is possible to obtain other types of ceramic capacitor, these are the main types that can be found today. Of these the surface mount variety is used in the greatest quantities by far because of the manufacturing methods used these days for electronic equipment.

Advantages of Using GSM Antennas

On October 24, 2017, in Antenna, by Lambert

“Like any wireless technology, however, GSM communications are dependent on antennas.”

 

Global System for Mobile (GSM) communication systems are fast becoming the standard in mobile phones everywhere. The GSM system allows users to talk virtually anywhere in the world. It’s essentially a global roaming service that’s based on satellite communications, and it offers extraordinary flexibility and freedom for mobile phone users who have embraced this wireless technology. Like any wireless technology, however, GSM communications are dependent on antennas. That means that GSM services, and later generations of the technology like EDGE, UMTS, and HSDPA, are in constant need of custom antenna designers to help them keep up with customer demand and to introduce new innovations to the marketplace.

 

There are many advantages to using GSM technology, such as:

 

  • Global roaming
  • The ability to switch services while keeping the same phone
  • The ability to send text messages
  • A universal emergency number, so emergency services can be called anywhere in the world without knowing the local number

What Is a Solar Charge Controller?

On October 20, 2017, in Solar Equipment, by Lambert

A solar charge controller manages the power going into the battery bank from the solar array.  It ensures that the deep cycle batteries are not overcharged during the day and that the power doesn’t run backwards to the solar panels overnight and drains the batteries. Some charge controllers are available with additional capabilities, like lighting and load control, but managing the power is its primary job.

 

A solar charge controller is available in two different technologies, PWM and MPPT. How they perform in a system is very different from each other. An MPPT charge controller is more expensive than a PWM charge controller, and it is often worth it to pay the extra money.

 

PWM Solar Charge Controller

A PWM solar charge controller stands for “Pulse Width Modulation”. These operate by making a connection directly from the solar array to the battery bank. During bulk charging, when there is a continuous connection from the array to the battery bank, the array output voltage is ‘pulled down’ to the battery voltage. As the battery charges, the voltage of the battery rises, so the voltage output of the solar panel rises as well, using more of the solar power as it charges. As a result, you need to make sure you match the nominal voltage of the solar array with the voltage of the battery bank. *Note that when we refer to a 12V solar panel that means a panel that is designed to work with a 12V battery. The actual voltage of a 12V solar panel, when connected to a load, is close to 18 Vmp (Volts at maximum power). This is because a higher voltage source is required to charge a battery. If the battery and solar panel both started at the same voltage, the battery would not charge.

 

A 12V solar panel can charge a 12V battery. A 24V solar panel or solar array (two 12V panels wired in series) is needed for a 24V battery bank, and 48V array is needed for 48V bank. If you try to charge a 12V battery with a 24V solar panel, you will be throwing over half of the panel’s power away. If you try to charge a 24V battery bank with a 12V solar panel, you will be throwing away 100% of the panel’s potential, and may actually drain the battery as well.

 

MPPT Solar Charge Controller

An MPPT solar charge controller stands for “Maximum Power Point Tracking”.  It will measure the Vmp voltage of the panel, and down-converts the PV voltage to the battery voltage. Because power into the charge controller equals power out of the charge controller, when the voltage is dropped to match the battery bank, the current is raised, so you are using more of the available power from the panel. You can use a higher voltage solar array than battery, like the 60 cell nominal 20V grid-tie solar panels that are more readily available. With a 20V solar panel, you can charge a 12V battery bank, or two in series can charge up to a 24V battery bank, and three in series can charge up to a 48V battery bank. This opens up a whole wide range of solar panels that now can be used for your off-grid solar system.

 

The Key Features Of A Solar Charge Controller Are:

 

  • Multistage Charging Of Battery Bank:

Changes the amount of power set to the batteries based on its charge level, for healthier batteries.

  • Reverse Current Protection:

Stop the solar panels from draining the batteries at night when there is no power coming from the solar panels.

  • Low Voltage Disconnect:

Turn off attached load when battery is low and turns it back on when the battery is charged back up.

  • Lighting Control:

Turn attached light on and off based on dusk and dawn. Many controllers are configurable, allowing settings for a few hours or all night, or somewhere in between.

  • Display:

May show voltage of battery bank, state of charge, amps coming in from solar panel.

 

If you are looking for high quality solar charge controllers, I recommend that you can visit the website of Power Master Technology Co., Ltd. which is the professional solar panel manufacturer in the industry. You can find numerous solar charge controller related products on their website. Feel free to send inquiries to Power Master to obtain the product you need.

The positive temperature coefficient, PTC thermistor has two types: silistor & switching PTC have very different characteristics.

 

As the name indicates a positive temperature coefficient, PTC thermistor has a response in which the resistance rises with increasing temperature.

 

There are two types of PTC thermistor which have very different characteristics, one showing a linear increase, whilst the other shows a sudden change in resistance.

 

PTC thermistor outline

 

PTC thermistors can be divided into two types according to their structure and the materials used. The two types of PTC thermistor have very different characteristics:

 

  • Switching PTC thermistor:

This form of PTC thermistor is used in heaters, sensors and specialized versions are also used as resettable fuses. Switching type NTC thermistors have a highly non-linear curve. The resistance at first falls slightly with increasing temperature, and then at a critical temperature the resistance increases dramatically, thereby acting virtually as a switch. This makes it ideal in many protection devices.

  • Silistor:

The silistor PTC thermistor uses a semiconductor as its base material and it is characterized by a linear characteristic and as a result, the silistor is used in temperature sensors. The silistor PTC thermistor is generally manufactured from doped silicon, the level of doping determining the exact characteristics.

 

Switching PTC thermistor basics

 

As the switching PTC thermistor is very widely used form, it warrants further explanation as it has an unusual characteristic.

 

Switching PTC thermistors are typically fabricated from polycrystalline materials including barium carbonate or titanium oxide with added materials including tantalum, silica, or manganese, etc.

 

The materials are mixed and ground to fine powders and finally compressed into the required shapes before being sintered. Contacts are then added and the thermistor is encapsulated.

 

The characteristic of the switching PTC thermistor shows that the device has a highly non-linear characteristic. As the temperature increases, the resistance first decreases, then rising slightly before it reaches a critical temperature, TC. At the critical temperature the resistance increases sharply for any increase in temperature, before finally leveling off and falling slightly.

 

A similar type of device is known as a Polymer PTC. These devices consist of a plastic element into which carbon grains are embedded. When cool, the carbon is able to conduct electricity, but as the temperature increase the carbon grains move further away as a result of expansion and conduction falls rapidly. In this way the device acts like a switch in the same way as the more traditional PTC thermistors.

 

PTC thermistor operational modes

 

There are two main ways in which switching PTC thermistors are generally used.

 

  • Self-heating mode:

When used in the self-heating mode, current is passed through the thermistor, often in series with the item being controlled. As it heats up as a result of the current, it reaches a point where the critical temperature is reached and the resistance increases significantly. In this way it operates in a self-heating mode and can be used as a safety cut-out or regulator.

 

  • Sensor mode:

In this mode, a minimum amount of current is passed through the device and PTC thermistor senses the surrounding temperature. Keeping the current to a minimum ensures the self-heating effect is negligible and only the surrounding temperature affects the device. As the surroundings heat the device it may reach its critical temperature at which point the resistance will significantly increase.

 

Switching PTC thermistor applications

 

Switching thermistors are a very useful form of electronic component. It can perform functions with a single component that would require far more complex circuitry should any other technique be used.

 

  • In-rush protection:

Some electrical items like motors and transformers have a large surge of current at switch on. This gives rise to very high peaks of current which can cause spikes on the power line, or cause damage in some instances. PTC thermistors can be used to reduce the level of the inrush current and thereby prevent the spikes or damage occurring.

 

  • Overcurrent protection:

In this application, the PTC thermistor is placed in series with the load and uses the self-heating effect. The current taken under normal conditions should enable the thermistor to operate in its flat resistance curve area. However if an over-current condition arises, then the thermistor will carry more current and the temperature will rise more causing it to rise beyond the critical temperature when the resistance will rise significantly causing the current to drop.

 

PTC thermistor circuit symbol

 

It is sometimes necessary to indicate the type of thermistor being used on a circuit diagram. Accordingly the IEC have a special PTC thermistor circuit symbol that can be used.

 

As seen the circuit symbol utilizes the characters +t° to give an indication of the positive temperature coefficient.

 

Positive temperature coefficient, PTC thermistors are used in many electronic circuits and for a variety of functions. It is essential to check that the correct type is selected for any given circuit to ensure that its characteristic meets the requirements.

How to Choose an Electric Drop Bolt?

On August 28, 2017, in Electrode Products, by Lambert

Electric drop Bolt is called electric drop down bolt, drop bolts lock, electric bolt lock. It is usually installed to control the glass doors/gates. Electric drop bolt locks can be used with any kind of electronic digital on/off switches, magnetic stripe card reader, proximity card reader and biological access control system.

 

Drop bolt is made up of 2 parts-the face plate and body. Additionally there is a strike plate.

Electric Drop Bolt

 

The face plate is usually made of aluminum and body made of stainless steel.

 

Sensor Type – Generally there are 2 types sensor electric drop bolt in the market. Ball bearing sensor and magnetic sensor.

 

Working mode – There are 2 types working mode drop bolts, the failsafe and failsecure modes. Failsafe mode drop bolt is widely used nowadays due to when the power cut offer the drop bolt latch is unlocking. It ensures the people escape.

The failsecure drop bolt is used only in the high security place such as prisons which do not allow access if no valid command, regardless of any reasons.

 

Delay – Some drop bolts have delay function buy some not. The delay function is helpful to keep the door close properly every time when people push/pull the door and leave it closing by floor spring. The delay function provides the drop bolts ability that relock only when the door do not swing anymore. This is very useful to the door that floor spring works not well enough. It avoids the door impact the bolt latch by mistake. The user could adjust the delay time from 3/6/9 seconds as needs.

 

Cables – There are different quantity cables drop bolt in market. The different cable quantity drop bolts have different performance. 2-cable drop bolt is a basic level product which provides the basic function. When power on, the current drive the circle to generate electromagnetic effect, which attracts the spring sheet to keep locking. It is easy heat for a long term using. And the current fluctuate may easily causes malfunction to drop bolt.

 

Multi cables drop bolt provide more features such as door contact, REX, etc. A unique logic circuit keeps the drop-bolt retracted until the door has been closed and is properly aligned to assure engagement of the lock bolt.

What is RFID?

 

Radio-frequency identification device is a technology that retrieves the status and presence of a thing to which it is attached to remotely. These devices will track the objects automatically and sends the embedded information to the processors.

 

Typical components of RFID system

 

An RFID system contains an RFID tag, RFID reader, RFID antenna, and RFID package.

 

RFID tag is attached to the item that needs to be tracked and identified.

 

RFID antenna will detect the RFID tag when it comes in range.

 

RFID reader reads the RFID tags and authenticates its presence.

 

RFID package contains the server and software and transmits the information to all other applications.

 

Application of RFID systems

 

To simplify, RFID systems do the same function as of a BAR-CODES, but when it comes to applications they are widely spread as RFID systems doesn’t need to maintain contact with the scanners as in case of BAR-CODE. High Frequency RFID systems doesn’t necessarily to be appear in the line of sight, especially such are applied for livestock tracking, Missile tracking, automobile tracking through assembly lines and most importantly in case of vehicle tracking.

 

Security potential

 

Increasing security measures through CCTV cameras has already outdated, the latest technology implies to the usage of RFID readers wherever the security is needed along with authentication.

 

They can be installed in a library, home, and elsewhere domestically to secure the important files, books, and expensive things, so that even when they are found missing they can be easily detected with the help of local servers that are giving location information.

 

They can also be placed in a vehicle, thanks to their non-contact readable characteristic feature as the vehicles can be tracked along the route as they can use the location provided by the nearest GSM signal boosting towers and thus one can keep notice of their vehicles.

 

The size of the smallest developed RFID is 0.05mm × 0.05mm size and the average size would be around 3mm x 3mm. As we go cheaper the size will be increased consistently. Their dimensions make them invisible to see which a plus point in terms of security measures is.

Whether you’re looking to purchase a new treadmill or looking to update an existing one, knowing about which kind of motor to look for is vital to the success of your treadmill use. The motor is the main hub and carries the most weight mechanically. They vary in their abilities and capacities and are not all alike. It is essential to consider a few different variables with its motor before you make your treadmill purchase. This will ensure that you will bring the right treadmill home that is best-suited for your lifestyle and fitness goals.

 

Aside from the user, the motor does the most work in the treadmill. It is imperative that quality be assessed for long-term use, especially for more serious treadmill users. Poor quality motors are likely to overheat and require unnecessary repairs. The best way to check if your motor is a good quality motor is by checking the manufacturer warranty. A high-quality motor will have a longer warranty period and is a safer investment. In almost all of our treadmill reviews, we help you by giving the horsepower of the motor and by using the information below can determine if it is best suited for what you would use it for. One company that is known for high quality treadmill motors are Sole treadmills. They deliver a great product and stand behind it.

 

When it comes down to the nuts and bolts of the matter, treadmill motors are not wholly difficult to understand. Treadmill motor energy is measured in horsepower (HP) and can be sorted into three different rating systems:

 

  1. Peak Duty:

Generally the weakest. “Peak” stands for the peak horsepower that the treadmill will reach and no more.

  1. Treadmill Duty:

In-between peak and continuous

  1. Continuous Duty:

The highest rank. The number associated will describe how much power is maintained throughout the workout.

 

While many motors will claim to be of identical horsepower, it is pertinent to note that every motor is not built the same. Cheaper prices mean that the product consists of poorly made parts. Do not be swayed solely by low prices. A treadmill that originally cost $1000 or more is likely to possess a durable motor. Less expensive models are not likely to have a reliable motor installed.

 

Assess what kind of use the treadmill will predominantly be used for. The degree of exercise must be taken into account to make sure your treadmill motor reflects your lifestyle. Certain levels of exercise require specific amounts of horsepower; will it be for walking, jogging, running, or all three? Consider the following:

 

  • For walkers: a 2.0 horsepower continuous duty motor will suffice
  • For joggers: 2.5 horsepower continuous duty should be the minimum
  • For runners: 3.0 horsepower continuous duty or higher

 

Also note that if any of the users of the treadmill weigh over 200 pounds, HP should be increased by .5 for proper support, no matter the fitness goals. This means the HP should be at least 2.5 HP for walkers, 3.0 for joggers, and 3.5 for runners. Such precaution will extend the life of your motor.

 

As for sound, note that motors employing direct current (or known as DC) cause less noise compared to motors that use alternate current (also known as AC). Remember this when deciding where to place your treadmill, especially if you watch the television while you walk or run, or if the treadmill will be in a high traffic area of the home.

Choosing the right gateway or router isn’t all there is to successful mobile networking. Signal quality is essential and this can only be guaranteed by picking the right 3G or 4G LTE antenna and solutions.

 

Selecting the right antenna

When selecting an antenna the following considerations need to be made:

 

Where will the antenna need to be situated?

If outside then the antenna will need the appropriate IP rating to ensure it is protected against dust and water. If inside then it will need to be of a suitable size.

 

What application is the antenna being used for?

Different applications require different types of antennas, for example WiFi and GPS will require their own antennas in addition to cellular antennas.

 

What environment is the antenna being placed in?

For example, vehicular or industrial locations will require an antenna that is suitably ruggedized with the appropriate fixtures.

 

What is the quality of the signal in the intended location?

If the signal quality is poor then a high gain external antenna may suit it best.

 

What frequency band are you using?

Most high quality antennas cover a wide range of frequencies, but some cheaper antennas are only suitable for one type of connectivity, e.g. 2G, 3G or 4G.

 

How visible will the antenna be?

If it is highly visible in a prominent location then it may be important that it is aesthetically suitable.

 

Where and how does the antenna need to be fixed?

Different locations require for the antenna to be attached in different places, for example on a window, wall or ceiling, and will therefore require different types of fixtures, for example screw-on, stick-on or magnetic.

 

After these questions have been addressed, the process of selecting the correct 4G LTE antenna can begin.

 

Established in 1993, Evercom Communication specializes in manufacturing 4G LTE antennas. The new next generation of in-vehicle connectivity through 4G LTE solution can be monitored and managed remotely from the cloud.
