Who Should Get A LCD Monitor Arm?

Posted on by

If you work at a computer for long periods of time, an ergonomic setup can help protect your health and well-being. To learn about ideal workstation setups, we referred to the work of ergonomics expert Alan Hedge, director of the Human Factors and Ergonomics teaching and research programs at Cornell University.

 

In Ergonomic Workplace Design for Health, Wellness, and Productivity, Hedge recommends that the top of a screen be about 2 to 3 inches above eye level, because human eyes see more below the horizon line than above. To find the right height, Hedge advises, ”the worker should sit back in their chair in a slight recline, at an angle of around 100°-110°, then they should hold their right arm out horizontally at shoulder level, and their middle finger should almost touch the center of the screen.” Getting your monitor position just right will let you see most of the screen without having to crane your neck. Hedge also recommends placing your keyboard just below your elbow level to ensure good posture and maintaining an elbow angle of 90 degrees or greater to prevent nerve compression.

 

On a laptop, this arrangement isn’t possible, because its screen and keyboard are so close together. If you use a stand-alone monitor to raise your gaze, you’re already helping your posture, but you may need a monitor arm to get the positioning just right.

 

A monitor arm can help prevent back and neck pain by properly positioning your screen. Especially if you alternate between sitting and standing at your desk, share a workstation with people of varying height, or just need easy, on-the-fly adjustments, you should consider a monitor arm like the ones we recommend here.

 

Monitor arms aren’t necessary for every person or every desk setup. If you don’t need to adjust your monitor’s height frequently, you can achieve ideal screen placement with a monitor stand, which is much cheaper and easier to set up, or even with a sturdy book or two. Our monitor picks come with adjustable stands that work for most people in most setups. But those included stands take up more space on your desk, lack the height to serve very tall people, lack the range for a proper sit/stand setup, and don’t move left and right, move forward and back, or rotate. If you need those features, you should get a monitor arm.

What are Electronic Deadbolt Locks?

Posted on by

Having a safe and secure door lock is the first step toward ensuring safety of the residence. For decades, this work was done by the simple key and locks.

 

However, these locks could be easily damaged and instances of break in increased. Looking for the appropriate solution to this problem, spring bolt lock came into use.

 

These locks consist of spring loaded bolt with an angled edge. When the door is completely closed, the spring engages and latch bolt holds the door closed. However, with time the use of deadbolt came into existence.

 

These locks are more convenient to use than the spring bolt locks. A typical deadbolt lock is handled manually and requires turning a cylindrical knob so as to open the door. Such deadbolts can have single cylinder requiring one key or double cylinder requiring two keys.

 

However, the problem with a simple deadbolt lock is that it requires a key. Most of the times, a person may forget the key. Besides, these simple deadbolts were inefficient to be used in massive buildings which require a large number of locks. Hence, an improvement was made in the deadbolts which now operated electronically without needing any manual effort.

 

Such deadbolts are called electronic deadbolt locks. In rest of the article, we would be discussing the various aspects of using an electronic deadbolt locks.

 

Electronic Deadbolt Lock

Electronic locks have become one of the most popular security locks used for doors in both commercial and residential buildings. Unlike simple deadbolt locks, these locks do not require keys for operation.

 

The actions of these locks are more accurate. Moreover, these locks do not allow easy break in into the building. Thus, the locks are widely used in hospitals, corporate offices, defense centers and private buildings. To open a lock, one need to feed a combination of codes which the related electric circuits analyses.

 

These code combinations can be fed either using cards or keypad. In most of the commercial and govt. buildings, cards are widely used.

 

How Does Such Lock Work?

The lock contains an electric circuit. The lock has knob on both sides of the door. The electronic circuit is arranged to read the input code. Once input code is fed, the circuit reads the code and matches it with the stored code. If the two matches, then, electrical operated bolt is activated and consequently the door is unlocked.

 

A battery is used to supply power for the circuit operation. The lock uses the solenoid or electric motor to activate the bolt mechanism.

 

Benefits of Deadbolt Locks

The electronic deadbolt locks have a numerous of advantages over the rest of the traditional deadbolt locks. Some of them are enlisted below:

 

  • Unlike simple deadbolt locks, the electronic deadbolt locks come with the patented digital technologies.
  • These locks are equipped with both key and electronic locking mechanism.
  • Multiples code combination can be stored which can allow several layers of security to the building.

 

Limitation of Deadbolt Locks

Despite of having brilliant features, there exist some factors which a cautious user must consider. Here, we enlist some of the limitations faced by the electronic deadbolt locks.

 

  • These locks are operated through solenoid or electric motors, thus, they need a large amount of power for effective functioning. However, the use of batteries has helped to solve this problem up to an extent.
  • If not installed properly, the cylindrical knob can be a hazard instead of providing safety to home.
  • The codes if guessed by someone else (other than the resident) can lead to awkward situation.

 

Features of A Good Deadbolt

There is a large number of electronic deadbolt locks available in the market. Thus, it is primary important for a buyer to judiciously choose the appropriate product for ensuring the home safety. In this regard, we present below some of the features which a good lock should possess. Hope that the buyers shall find it helpful before they go out for purchasing a new product.

 

  • The installation of the electronic deadbolt lock should be simple and inexpensive requiring minimum alteration to the premises.
  • The lock should have the capability of storing more than one combination so that different person can have the entry (with prior knowledge of the resident) without knowing the actual combination used by the resident of the house.
  • The lock should be capable of having the number of digits as combination according to the choice of the residents. That means the lock should not restrict the resident from choosing any combination as per his wish.
  • It is advisable to buy a double cylinder electronic deadbolt lock installed with glass windows.
  • A good electronic deadbolt lock should be battery operated.
  • It should use both card and keypad number for feeding the combination code.

 

Summary

The electronic deadbolt locks have rejuvenated the security issues concerning a residential or industrial building. The locks most popularly used in industrial buildings have enabled to gear up the best security measures.

 

Besides, the locks are being extensively used in buildings having strategic significance. These locks ensure null break in and are most convenient to use. There is no need for key as the locks are electric automated. Moreover, the locks also have the feature of storing more than one security code.

 

This unique feature adds to the security level of the building. However, one has to carefully choose the appropriate security code so that it is not easily guessed by someone else. With the use of such locks, one can surely enjoy the utmost security and safety level.

How To Choose An Electric Strike Lock

Posted on by

The electric strike lock may not be a colorful component in a locking system, but it is one of the most important. This type of lock is not only cost-effective, but also a better alternative than electrified lock mechanisms in some circumstances.

 

Reasons for An Electric Strike Lock

Electric strikes are devices installed on doors to allow entry via an access system or remote release system.

 

Unlike a magnetic lock, a strike does not secure a door; that’s the responsibility of the door handle or lockset. The electric strike allows access to a secured door with a key card, pass, etc., without the need for a key to the lockset.

 

Types of Electric Strike Locks

There are two styles of electric strike lock:

 

  • Fail-Safe Locks

Fail-safe locks (also called fail-open) operate as a magnetic lock would. A direct electric current is applied to the strike, causing the door to lock. In a power failure, the door can be pushed or pulled open.

 

  • Fail-Secure Locks

Fail-secure locks (also called non-fail safe or fail-locked) open when an electric current is applied to them. In a power failure, this kind of lock will remain locked, although the mechanical can still be used to open the door from the inside.

 

An electric strike lock is useful on any door where high traffic occurs and requires monitoring or where items need to be secured and safeguarded. It also regulates employee access and helps prevent employee theft.

 

Choosing An Electric Strike Lock

Choosing the right kind of electric strike lock depends on the kind of door you have. The door material, and whether the door is internal or external, double or single, determines which electric strike lock is best. Strikes are available for nearly all door styles and of various material types, like aluminum and timber.

 

Security and Monitoring Requirements

The level of security desired will impact the type of strike that is best for your doors and circumstance.

 

For example, a low-security situation with no defined holding force may only require a low-cost electric strike. However, in a high-security environment, a strike with a maximum holding force of 1,500 pounds or more may be necessary.

 

Most electric strike manufacturers produce strikes with or without a monitoring facility. Door state monitoring should involve the use of a separate reed switch on the door or frame.

 

Type of Lockset

Your electric strike lock must be compatible with the type of lockset on your door. Use the lockset manufacturer’s compatibility chart to determine if your electric strike works with the lockset in question.

 

Latch Bolt Dimensions

Similar to a lockset, your choice of electric strike lock will need to accommodate the type of lock bolt sizes. Make sure that the centerline location of the latch bolt is correctly positioned around the centerline of the lockset to ensure that the lock will work as desired.

 

Power Needs

Most electric strike locks are 24 VDC, although 12 and 24 VAC options are also available. Choosing AC or DC power is critical because each strike application is different. Consider regulated or filtered power sources where practical as these sources will extend life to the strike’s operating capacity.

 

Code Compliance

Fail-secure electric strike locks must be used on fire-rated doors so that the door automatically goes into a locked position when the power is turned off. Because fail-safe locks go into an unlocked state when no power is applied, they do not meet code requirements for fire doors.

 

Consult the professional electric locks company if you are uncertain about what kind of electric strike lock you need for your building or office. Here, I recommend that you can visit Pongee Industries Co., Ltd.

 

Pongee is an experienced automatic identification systems manufacturer in Taiwan. They have different type of high quality electric strike locks to meet various needs of clients. If you need more information about strike locks, welcome to check out their product pages and feel free to send inquiry to Pongee.

An Introduction to Unmanned Aircraft Systems

Posted on by

Unmanned Aircraft
Unmanned Aircraft Systems (UAS) are a new and evolutionary component of the aviation system, offering several new and exciting opportunities, as well as a number of challenges.

 

Unmanned aircraft come in a variety of shapes and sizes, ranging from small handheld types up to large aircraft, potentially a similar size to airliners and, just like manned aircraft, and they may be of a fixed wing design, rotary winged, or a combination of both.

 

Unmanned Aircraft may also be referred to as:

 

  • Drones
  • Remotely Piloted Aircraft Systems (RPAS)
  • Unmanned Aerial Vehicles (UAV)
  • Model Aircraft
  • Radio Controlled Aircraft

 

Regardless of the name used, they all share the common characteristic that the person responsible for piloting the aircraft is not onboard it. Just like any other aircraft however, an unmanned aircraft must always be flown in a safe manner, both with respect to other aircraft in the air and also to people and properties on the ground.

 

Types of Operation

The key first principle when discussing the regulation of any UAS is to determine how it is being operated and what process is being used to avoid it colliding with other aircraft, objects or people, which is the primary responsibility of anyone who flies any aircraft.

 

UAS are either operated:

 

Within the Visual Line Of Sight (VLOS) of the person flying the aircraft

This means that the aircraft must be able to be clearly seen by the person flying it at all times when it is airborne. By doing this, the person flying the aircraft is able to monitor its flight path and so manoeuvre it clear of anything that it may collide with.  While corrective spectacles can be used to look at the aircraft, the use of binoculars, telescopes, or any other image enhancing devices are not permitted.

 

In simple terms, the aircraft must not be flown out of sight of a human eye.

 

Beyond the Visual Line Of Sight (BVLOS) of the person flying the aircraft

If the person flying the aircraft is unable to maintain direct unaided visual contact with it while it is airborne, then an alternative method of collision avoidance must be employed in order to ensure that it can still be flown safely.

 

BVLOS flight will normally require either:

 

  • A technical capability which is equivalent to the ability of a pilot of a manned aircraft uses to ‘see and avoid’ potential conflictions – this is referred to as a Detect and Avoid (DAA) capability
  • A block of airspace to operate in which the unmanned aircraft is ‘segregated’ from other aircraft – because other aircraft are not permitted to enter this airspace block, the unmanned aircraft can operate without the risk of collision, or the need for other collision avoidance capabilities
  • Clear evidence that the intended operation will have ‘no aviation threat’ and that the safety of persons and objects on the ground has been properly addressed.

 

What Is The Purpose of Your Flight?

Your flight will broadly fall into one of three types as follows:

 

  • Recreational – where the flight is being conducted as a pastime purely as an ‘enjoyment’ or sporting activity
  • Commercial – where the flight is being conducted for business purposes in return for specific remuneration or other form of valuable consideration.
  • (a specific definition of a commercial operation is contained within the ‘Commercial Operations with Small Drones’ section)
  • Private/Non-Commercial – flights that are either:
    • not considered to be recreational
    • flown for business purposes, but without any remuneration or other valuable consideration being involved

 

While the regulations are the same for all types of flight, there are some specific additional requirements placed on commercial operations involving small unmanned aircraft.

Electric Chain Hoists – Choose The Right One For Your Industry

Posted on by

Electric chain hoists are used in industry and related areas to lift heavy objects, equipment, or machinery. By using electric chain hoists, the task is done faster and easily with less risk involved. They are much easier and sophisticated to use than manual chain hoists. Moreover, they are more convenient and can achieve the task more efficiently than manual chain-hoists. Electric chain hoists are available in a variety of sizes and for a variety of lifting equipment depending upon the load to be lifted.

 

These days, it is not hard for one to find the hoists that you require for your type of industry. These hoists are now manufactured by reputed manufacturers in Taiwan as well as abroad. Many online dealers also stock reputed brands, so you need to know the exact specifications that you require for lifting the required loads.

 

Nowadays, hoists have a variety of features and come with a range of price tags. Depending upon the type of the hoist you require, it is essential you are away of the safety parameters and whether the hoist will stand up to the rigorous operational requirements. Therefore, you should be knowledgeable about the operations requirements of the hoist you propose you wish to purchase. At the same time, you should be aware of the quality standards that are applicable to electric chain hoists. Do not go for a cheaper hoist if you are in a position to purchase a more expensive one. A cheap hoist may leave out the safety and quality parameters essential under various rules, laws, and regulations.

 

A manual chain can lift up a lighter load, but an electric chain hoist can be used to lift heavier loads. Nevertheless, they should not be used for lifting loads beyond their lifting capacity. Therefore, it is always advisable to check the rated capacity of the electric chain hoist before actually buying it. At times, there are circumstances which require continuous operation of the hoist, so be sure that the operators do not exceed the rated capacity. For example, if the rated capacity is 30 minutes on and 30 minutes off, you cannot run the hoist more than this capacity.

 

A torque limiting device on the hoist will prevent accidental or intentional overload. Also check for safety features like upper and lower limit switches and low voltage controls. A stop button can take care of emergency situations. A variety of speed capacities are available so you can make the right choice while purchasing a hoist. There will be a number of manufacturers providing you with the same types or hoists.

 

They are also available in different speed capacities and speeds to be able to endure a variety of handling procedures. Since there are many manufacturers offering various types of hoists, you need to know exactly what you are going to buy. Therefore, while buying an electric chain hoist, do not buy the ones that seem cheap or spurious for you, or do not even buy the ones that violate safety norms. Train your staff adequately on the use of electric chain hoists and always read the operation manual before installation and operation.

GSM Antennas and Their Uses

Posted on by

What Is A GSM Antenna?

An antenna is an electrical device which converts electrical currents into radio waves and vice versa. It is an essential part of a radio allowing a radio frequency (RF) signal generated by a radio device to be sent or received on a particular frequency or frequencies. A GSM antenna can operate on 824-894 MHz, 890-960MHz, 1710-1880MHz and 1850-1990MHz. Often, antennas can operate on more than one frequency range. In this case they are often referred to as dual band (2 frequencies), tri band (3 frequencies) or quad band (4 frequencies).

 

Why Do I Need An Antenna?

The GSM antenna receives or transmits the RF signal – without it the radio system will not work. Antennas are used in all systems using wireless equipment such as key fobs for cars, garage door entry systems, RFID tags, baby monitors and mobile phones.

 

How Does A GSM Antenna Work?

An antenna is made using a conductive strip or wire usually made of metal. This allows an electrical current to pass through which creates a magnetic current. Depending on the frequency, this will create a wavelength which is a certain size. The lower the frequency the longer the wavelength and this will make a GSM signal transmits further.

 

What Should I Look For In An Antenna?

Antennas come in different shapes and sizes and depend on how they are being used. Firstly however, they radiate in 2 ways. The first is the more common – OMNI directional antenna. This allows a 360° radiation pattern so as to transmit and receive in any direction in a circular pattern. Directional antennas transmit and receive RF signals in a limited direction and need to point in the general direction of the other radio.

 

As examples, an antenna on a walkie talkie would be OMNI directional, giving an all-round coverage. A TV antenna mounted on the roof of a house is a Yagi antenna which is directional – pointing in the direction of a TV transmitting power. This allows a concentration of signal to be sent or received.

 

How Many Types Of GSM Antennas Are There?

 

Once an OMNI directional or directional antenna has been determined, there are 6 generally accepted styles of GSM antenna. These depend on the use.

 

  • Embedded antennas are used for when the antenna is being fitted inside equipment.
  • Through hole mount antennas are used in permanent installations and fit via a mounting bolt.
  • Magnetic mount antennas are usually reserved for temporary installations or in evaluation kits.
  • Direct connect antennas screw directly to GSM modems or the back of GSM terminal equipment. External or base station mount GSM antennas often fit on walls and are used in remote locations
  • For wireless telemetry or alarm panel installations.
  • Adhesive mount antennas stick onto glass or other nonmetallic surfaces.

Ceramic Capacitors and Reliable Capacitors Manufacturer

Posted on by

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.

Technologies of Proximity Card Reader

Posted on by

Passive Proximity Readers

 

Nearly all building access cards based on proximity are passive. There are roughly 125 million cards used for accessing secured buildings today.

 

Passive technology implies there is no battery or power source required in the card. The proximity reader constantly transmits a low level fixed RF signal that transmits energy to the card. When the card is held at a certain distance from the reader, the RF signal is absorbed by a small coil inside the card and powers the card’s chip which contains a unique identification code. Once powered, the card transmits the code to the reader.

 

The advantages of proximity over other technologies are numerous: no moving parts, no mechanical wear, no slots, no read heads to maintain. The reader can be concealed inside walls or special enclosures and, even when the reader is surface mounted, it has no openings to jam or tamper. The card is the most secure and practically impossible to duplicate. Cards can usually be read through a purse or wallet and through most other nonmetallic materials. Card and reader orientation is not critical.

 

Reading ranges depend primarily on the reader. The larger the reading range, the larger the reader’s concealed antenna and hence, the size of the reader. There is a great variety of proximity readers designed for different environments including vandal-resistant mullion mount, smaller decor style and integrated keypad/reader units.

 

Active Proximity Readers

 

Active proximity technology implies there is a battery within the card. Since the card has power the range is greatly expanded (3-15 feet vs. 1-5 inches). The RF signal is low level (<1mw) but the frequency used is much higher. Applications tend to be uniquely applied, although recently the application in computer access control is more prevalent.

 

Orientation of the card and reader become important. Since the RF frequency is much higher several other effects may be noticed such as exact distance due to the fact that the signal bounces off of other object.

 

Active technology is useful where a hands-free (as opposed to contactless) data exchange is required. Since the range is much longer, it is generally not very practical for door access (except gated parking lots) since walking past the door may unlock the room. The typical application is to detect the presence of a person at a computer and allow access without intervention. Equally important is to automatically lock the computer when a person steps away.

 

Read range is adjustable between 3 to 15 feet.

 

Active cards are generally thicker (1/5 inch) as a result of the replaceable battery requirement

 

Presence Detectors

 

Sonar technology is a relatively new entrant as a tool for security with PCs.

 

In computer security there are two primary components to consider:

 

  1. Unlocking the ‘locked’ workstation, and
  2. Locking the workstation after the logon user leaves the station.

 

The first component generally gets the most attention and array of solutions while the second is generally handled by a time-out screen saver or company mandated policy. Both solutions for ‘2’ above are fraught with exposure issues.

 

The use of sonar technology is a means for detecting the presence or absence of an individual, and performing a specific operation when there is a change. It is important to understand there is no real identification of the user performed with this technology.

 

When a user steps away from an authorized session, the sonar device can detect this occurrence and send the appropriate keystrokes to secure the workstation (log off or lock). This improves solutions associated with policy since the device never forgets to lock. It is also a great improvement over a time-out in that this occurs immediately as opposed to a parameter set by the minute(s).

 

Likewise when the user steps up to a locked workstation, the appropriate keystrokes can be set to call up the logon dialog.

 

This technology can be a great aid for other forms of authentication such as biometrics.
