With crime on the rise - especially those of burglary, drug-related robberies, and kidnapping - it's wise to prepare in advance how you will protect your home and family. In the event of an attack or break-in, there are many ways to protect your family, but preparation is a must. Your family members, even those who are young, should have a plan.Weaponry to Protect, Not to KillThough many families have guns hidden away for protection, guns are dangerous. Accidents can occur within the family or in the event of trying to defend the family; the burglar could take the gun from you and murder everyone in the family. Also, there's often an emotional breakdown if someone is killed, even in self-defense. It's a good idea to have weaponry that de-mobilizes the burglar, but doesn't kill them. Some forms of weaponry that many are using include stun guns and pepper spray. How Stun Guns WorkStun guns disrupt the attacker's body by generating a high-voltage electrical charge with low amperage. The stun gun's charge applies much pressure but little intensity. The charge can pass through thick clothing and skin. Its charge is not intense enough to do damage to the attacker's body unless it is applied for extended periods of time.A stun gun can, however, confuse the attacker by sending mixed signals to his brain. He can become temporarily or partially paralyzed, confused and unbalanced. This can give you or a family member enough time to get away and contact the police. It's important not attempt any heroic acts; only use the stun gun as protection for your life or the lives of your family members. Then, get away as quickly as possible.Stun Gun VoltageStun guns can be chosen according to voltage. They might contain from 20,000 volts all the way up to about 1,000,000 volts! They usually operate on 9-volt batteries. The batteries supply the stun gun with electricity to an electrical circuit. Components within the circuit give the voltage a boost while reducing the amperage. The stun gun has electrodes, which are usually small metal pieces with a gap in between. The gap is where a conductor must be placed. The conductor, of course, may be the arm, shoulder or hand of your attacker! There are also liquid "stun guns" and taser guns. The Citizen's ProtectorFor ordinary home protection, citizens often choose medium-voltage stun guns that are easy to operate and store. There are stun guns that are disguised as umbrellas, flashlights, or other objects to create the element of surprise. Military personnel, security officers, and police officials often use more complex stun guns.Stun Guns: Where to Buy ThemYou can buy stun guns at home security outlets or stores in your hometown or in a nearby larger city. Or if you're pressed for time, there are places on the Internet that offer these products at great prices. You can shop for all sorts of security products online such as Talon stun guns, "pepper spray" s, alarms, and so forth. You can also save money by buying discount stun guns or even wholesale stun guns from an online store.Before making a purchase, check out the company to be sure it is a reputable business. Also, check with your state and city laws to be sure the type of stun gun you are buying is legal in your area.Don't leave your family unprotected. Although they can't be used in every situation, "wholesale stun guns" can give added security in these uncertain days!
Scuba (Self-Contained Underwater Breathing Apparatus) diving and its various equipment have gone a long way. It began in 360 B.C. when divers first used the air underneath a crude diving bell as their source of air when submerged in the water. Guglielmo de Lorena then developed this technology into a real diving bell that was fastened by slings on top of the shoulders. In the past, it took hundreds of years to develop the equipment that enabled man to explore the wonders of the underwater world. Today, with modern science, every diver finds himself engulfed with newer tools, proof of mans eagerness to make underwater exploration easier and more secure. Newer and better equipment like masks, dry and wet suits, fins, lights, oxygen tanks, weights, regulators, bags, buoyancy compensators and other accessories are easily available today. Each has been designed to make moving, swimming, and breathing easier.In purchasing equipment, the most important advice to remember is to ask experts on what to buy and why. Diving gears can be expensive, so, a few tips from other licensed divers and instructors would make the task of choosing less of a burden. But, on the other hand, the risks of the sport are often fatal and would depend on the quality of ones equipment. Take the breathing regulator for example. The machine is attached to the scuba tank. It decreases the pressure of the oxygen stored in the tank, making safe for the divers to breathe in the air. Another example is the "wet suit" . The durability and the strength of material ensure the bodys protection from intense temperatures, specifically the coldness under the depths of the ocean. No matter what the sport, the most important consideration that should be taken, is ones safety and freedom to fully enjoy the activity.
A top quality home theater isn't only about high-definition televisions and DVD players. It's also about the cables used to transmit programming through to these products. A type of cable that's proving to be a winner in excellent quality is the HDMI cable. HDMI stands for High-Definition Multimedia Interface, which is an audio/video connector interface used to transmit uncompressed digital signals. HDMI provides audio/video cables that will connect electronics such as an HD-DVD player, a personal computer, a set-top box, a video game console, or a Blu-ray Disc player to a digital television monitor or digital audio device. HDMI cable compatibility has also been introduced to the digital camera and camcorder world. Why HDMI Cables?The old saying goes, "If you're going to do something, do it right!" Any high quality home theater set-up is only as good as the cables used to transmit the digital information. You can have the best, most expensive HD-DVD player in the world, but your low-quality cables will hinder the sound and picture quality because the transmission is simply not good enough or powerful enough for your system to reach its maximum potential. With HDMI, you're getting a high-quality transmission to your high-quality system, which maximizes the quality of sound and picture as you view movies, use your computer, play a video game, listen to music, or whatever else!HDMI Cable Features and BenefitsRegular analogue cables convert the digital signal to analogue and then send it to the television monitor. The signal is then converted back to digital to be displayed, which can cause a loss of quality during the process. With HDMI cables, no conversion is necessary so there is no loss of quality. HDMI cables also transmit digital signals directly and in their purest form, eliminating the need for compression. Another benefit is HDMI can support large-screen viewing including plasma display panels and LCDs, from 625p up to 1125p, or even 1440p with HDMI 1.3 High-Speed cables. HDMI cables simplify the hook-up process because both video and audio signals are transmitted through a single cable. Also, HDMI cables offer users an interface that works with any audio/video source. In other words, all of their HDMI-equipped components can be enhanced with pure quality for pictures and sound. HDMI cables can support standard digital audio as well as enhanced and high-definition video, and 8-channel digital audio. HDMI cables can also support future upgrades with plenty of bandwidth to spare.Shopping for HDMI CablesHDMI cables come in different compatibilities, but fortunately the High-Speed HDMI will support standard systems. If you plan to upgrade in the near the future, it's a wise choice to go ahead and purchase the High-Speed cables, or 1.3 cables, which can transport 1080p video at 120 Hz easily. Any HDMI cable can support 8-channel audio, but not all cables will support special features such as Deep Color video. With Deep Color HDTV, look for a version number on the cables or for other hints on the packaging that the cable will support 30-bit Deep Color or True HD. You can easily find HDMI cables at affordable prices online. There are online electronics stores that offer all versions of HDMI cables along with other products including computer cables, iPod accessories, computer fans, "video cables" , audio cables, chargers, adapters, cell phone accessories, digital photo accessories, and more.Don't miss out on all your home theater system can offer. HDMI cables can bring you quality pictures and sound like never before!
A battery is a device that stores chemical energy and is available in an electric form. The batteries contain a series of electrochemical devices that contains one or more fuel cells, galvanic cells and flow cells. This electric battery is an interconnected array of one or more than one voltaic cells that are used in the cars, in torches, laptops, digital watches and almost every electronic goods that we use in our daily life. Series of battery cellsThe cells in the battery are connected either in parallel, in series or in both combinations. While the parallel combination of cells has the same voltage power as a single cell, it can supply a higher current than a single cell can. The parallel arrangements, however, suffer from a recurrent problem. If one cell discharges faster than its neighbor cell, then current will flow from the full cell to the empty cell, thereby wasting a lot of power and causing excess of overheating. Another marked disadvantage is if one of the cells gets short-circuited due to an internal fault, then its neighbor will be forced to discharge its maximum current into the faulty cell, thereby leading to sudden explosion. The capacity of a battery to store charge is often expressed in ampere hours [1 A.h = 3600 coulombs]. If the battery can provide one ampere [1A] of current for completely one hour then it is said to have a real-world capacity of 1 A.h. Types of batteriesThere are some common battery types that are used in everyday life. The different types include rechargeable and disposable batteries, homemade cells, and traction batteries and flow batteries. Disposable batteriesAlso called primary cells are intended to use only once until the chemical changed that induce electrical current supply are complete and the battery is then discarded. They are commonly used in smaller and portable objects with low current drain. They are usually contained in light drain and heavy drain appliances, digital cameras, watches, computer clocks, and hearing aids. Rechargeable batteriesThese are secondary cells that can be recharged after they have been drained. This is done by conveniently applying externally supplied electrical current that reverses the chemical reactions that usually occur in use. It is used in appliances like alarm systems, vehicles, vacuum tube radio sets, absorbed glass mats etc.Traction batteriesThese batteries are designed to provide power to move vehicles like electric cars and tow motors. A peculiar characteristic of traction batteries is the electrolytes in the batteries are gelled. Flow batteriesThey are a special class of battery that stores additional quantities of electrolyte outside the main power cell of the battery and are circulated throughout by pumps or through movement. They have a high capacity and are specially used in the marine appliances.So whether its your car, PC, laptop cell phone or MP3 player, the batteries are almost everywhere to make you electrically mobile.
