Electronic Pet Doors

When it comes to electronic pet doors, there is a huge variety in the market to choose from. These pet doors are made a little differently from the flap doors; they are more like grooved, sliding doors that reduce draft, in turn reducing the loss of heating and air conditioning. Being power driven, these doors are electronically operated by the sensor attached to the pet’s collar, allowing only your pet to come in and go out and not the strays.

The opening and the distance need to be adjusted until the pet becomes familiar with the door. Made up of golden brown, transparent lexan, it is framed in strong, black aluminium that is anodized. The interior plate is made up of textured acrylic, which can be painted black to match the exterior trim plate. These doors operate on 115 volts of current. The power cord is supplied, along with the kit, which contains two sensor keys (these sensors are of different sizes for small and big pets) and an attachable clip for the pet’s collar.

These doors can be installed anywhere from walls, doors, sliders to French windows and can be installed by the home handyman, too. Also available are electronic doors made of unbreakable lexan with a four-way setting. It includes a breakaway collar and batteries but locks only in one direction, which could perhaps be a disadvantage.

Infrared pet doors could also be an option. In addition to keeping the house safe, these doors also restrict entry to unwelcome pets from outside. This door comes with two infrared keys, along with the collar and an optional power transformer that allows you to use regular power so that you can save on batteries. Ideal for small pets, these doors can be fitted onto doors of a maximum of two inches depth, or on walls or glass.

Most of these doors have common features like magnetic collar keys, restricting the pet’s movements, and nearly all of them can be installed on a door, glass, or walls. There is another kind of a door that needs to be fitted onto a panel. These electronic panel doors have the same features as the other electronic doors except that they fit into an assembled panel. The large-size panels have various size and height options. Small and small/medium-sized doors come with collar keys, while smaller keys that are more appropriate for cats can be bought for a bit extra.

Whether one opts for an electronic pet door or an infrared door what matters most is the convenience these doors offer the pet owner and of course, pets, too.

Electronic Pest Control Is The Silent Killer

Pest Control is always for most in our minds around the end of spring and the beginning of summer when we see the pests come out in mass. There are several types of methods for best control including electronic pest control. Rats are one type of pest that we strive to get rid, not only are they unhealthy creatures, but they nibble at everything and damaged food sources. So electronic pest control has become more popular in order to get these and other pests under control.

Electronic pest control devices prevent pests from gaining access to a home, storage, or other areas on our property. The device has an ultrasonic sound that it emits, which the pests do not like. It’s kind of like creating a force field they can't step around.

Other factors related to electronic pest control are the silent operations of the device. While we cannot hear the device the pests certainly can. Unlike a bug zapper the electronic pest control device for rats and other vermin keeps silent so as not to disturb us.

Bug Zappers For Pest Control

Let us take a minute to look at the bug zappers. These are also an electronic pest control form. The bug zapper is for flying insects. The insects are attracted to the light inside and when they go to investigate they get zapped. These electronic pest control units are very handy for killing bugs, but they are not silent, in fact if you are out in the country without traffic sounds and other disturbances the bug zapper can be a little irritating. Of course so can the bugs.

Electronic pest control devices are safe for your children and pets. Unlike pesticides the electronic pest control route offers a safe way to keep the pests off your land or in the case of bugs killing them safely. You will want to check the devices to make sure they are working properly before you place them around your home. While it does not happen often there can be some defective devices. So make sure you test them before using them.

Safe Is Always Better

When you elect to use the safer method of electronic pest control devices you will find that they may work for a short time only before the pest such as locusts, rats, and other vermin reappear. It is best to check the devices regularly to make sure they are working. There are plenty of claims on either side of the fence that the electronic pest control devices work or do not work. The best way to find out for you is to research the products on the market and try them out.

Electronic pest control devices can help keep the pests away from your home. You may elect to use a couple of different methods for pest control, but know that the first defense is the electronic pest control devices.

Electronic Test Equipment

Electronics is a vast field of study encompassing systems and technologies that control the flow of electrons and other types of charged carriers in various devices such as valves and semiconductors. The application of electronics is fairly widespread and is often the base for the growth of technology. Almost every new or old invention uses the concepts of electronics. Electronics is one of the primary branches of electrical engineering. To put electrical engineering into practice, a large number of electrical devices and equipments are required to test the workability and durability of complex electrical machines and systems.

Electronic test equipment is usually simple and cheap though there are compound electrical gears that are more difficult to test. Electronic test equipment is often referred to as test gear. These devices generate stimulus signals in order to receive responses from electronic gadgets referred to as Devices under Test (DUTs). By using these devices, the functioning of the DUTs can be proven and faults can be tracked and repaired.

Electronic test equipment can range from a simple light bulb to complex computerized and automated testing systems. There are different types of test equipment available for testing different devices. Basic electronic test equipments are used for simple measurement of the capacity of voltage and current in common circuits. Such test gear includes devices such as voltmeters, ammeters, galvanometers, ohmmeters, multimeters, power supplies, signal and pulse generators and oscilloscopes. These devices are usually digital and check simple prototypes. Certain advanced and less commonly used equipment such as clamp meters, electrometers, EMF meters, RF probes and logic analyzers are used to test the operation of higher and advanced components. Most test equipment used generate signals and hence are called signal-generating devices. Signal generating devices such as frequency synthesizer, function generator, pulse generator and signal injectors are used to generate signals for testing the working of electrical circuits.

Electrical test equipments have extensive use in fields such as aerospace, defense, automobiles and telecommunication. The use of these equipments helps in reducing the need for future quality assurance tests.

Electronic Dog Doors

Because you maintain a hectic calendar, you probably have to leave your dog at home alone on many an occasion. The good thing is that dogs act as guards who keep strangers and intruders away from your property. There have been innumerable cases of burglary, however, where the dog doors were used as the point of entry. The plain hanging screen dog doors are major attractions for burglars as they prove easy to be opened. The bad thing is your poor dog needs to get in and out of the house when you’re not there.

To keep this from happening to you, buy electronic dog doors instead. Electronic dog doors are much safer because they can only be operated through the use of electronic keys. These electronic keys can be placed on the collars of your pets so that only it can gain access to the electronic passageway.

Electronic dog doors are endowed with a directional sensing system that determines the distance of the dog from the door. Information regarding the direction that the dog is going is sent to the dog door system, so it will not open when the dog is just walking around, sleeping, sitting or eating nearby. The door is only unlocked when the pet is aiming at the door’s exact direction.

Electronic dog doors are the best to use. With such a door, you can be assured that unwanted guests can never enter your home, and that all your belongings – including your dog – are always safe and secure.

Electronic Dog Fences

Electronic dog fences provide dog owners with an automated, electronic means to make sure their dogs do not go beyond the safety of their homes. It also helps dog owners make sure that their dogs do not do any inadvertent damage to other people's property.

It effectively keeps the dogs within the owner's property and helps dogs learn to know their boundaries. They are trained by the system to automatically stay away from the boundaries of the home. Electronic dog fences have the added advantage of not taking up any property space. They are totally controlled by the dog's collar, and the predefined areas the dog is allowed to stay in.

The great thing about electronic fences is the fact that they can be programmed and wired to protect other areas of your home that are prone to the playful mischief of your energetic dogs. This way you can protect fish ponds, flowerbeds, gardens, and other sensitive areas.

But how do these things work? They are pretty simple, if you come to think of it. Here is a step by step guide to how electronic dog fences are set up and used.

Your Dog's Electronic Fence

1. Area Wiring – First of all, thin antenna wires are buried around the perimeter of the areas you want off limits to your dog. These wires are usually parallel to your picket or perimeter fences that surround your property. These wires are light, not bulky and are pretty easy to install.

They can even be secured in non soil areas by means of normal attachments easily found at any hardware store. Just make sure they are safe from the elements and are not an impediment to your surroundings. These wires can be installed beside your fish pond, other pet cages, and off-limit areas.

The wiring can also be installed inside your home. It should be installed in a way that it does not become cumbersome. It can be laid out like normal cable wire. Just make sure it is secured to the walls or to stable furniture and is beyond the reach of toddlers or your pets. You could even put it under you rug or under your carpet.

2. Pet Collar – Your pet then is made to wear a special collar that can receive signals from the wires you just installed. It is this collar that acts as the fence. Your pet should be wearing the collar for the system to work. Without the collar, the electronic fence will uselessly benign.

The collar works using radio frequency and has a specially installed radio receiver to pick up signals from the antenna wires in your territory.

3. Train Your Dog – the systems sets off a very mild and harmless shock to the dog whenever it crosses the boundaries marked by the wires. The shock is just like static and will cause no harm to your dog. All it does is offer a small irritating ‘reminder' to keep your dogs from moving beyond their permitted areas.

Also before it emits the shock, it gives off high-frequency beeps to warn the dog. Whenever the dog hears the beeps it will be alerted to the fact that the shock would come if the warning is not heeded. This ensures that the pet will not have to be reminded physically as much as it will be by audio.

You should also mark the areas off limits by using visual aids such as flags, and other visual aids. As the dog gradually understands and respects the boundaries, it will no longer need these aids to avoid the areas altogether.

Warnings and Conclusions Some owners are not comfortable with the fact that mild static is used to remind their pets of their boundaries. However, it should be noted that it is non-harmful and is a great alternative to cooping up a pet within a dark and dingy cage beyond the dog's comfort. Also electronic fences do not protect your dog against robbers as cages do. Thieves have to work at a cage or a series of gates to get to your dog. Although it keeps your pets from going out too far from the home, it does not keep others away from coming into your home.

Electronic Dog Training Collar

Using an electronic dog training collar is the fastest and most humane way to train your dog. If you really love your dog and want to teach the basic obedience that will keep it safe then an electronic dog collar is the answer. Professional dog trainers especially those who train working dogs almost always employ an electronic dog training collar within their training program. Only village idiots and people who have no experience with electronic dog collars feel they are cruel to the dog. That being said if you have not seen the results of properly used quality electronic dog collar on a dog then you will find it hard to realize how fast a dog will learn.

The first thing you need to understand is that electronic dog training collars are part of any valid training program. They are not used just for correcting dogs with bad habits or behavior. A good dog trainer will use an electronic dog collar on any dog no matter what its demeanor or mentality. Many times we trainers describe dogs as being soft or hard and as such so of us are reluctant to use an electronic dog collar on a so called soft dog. Proper correction and stimulation levels will provide training communication that will benefit any dog. The electronic dog training collar will do the job that no other dog training tool can accomplish.

An electronic dog training collar provides positive enforcement or punishment. A dog that has a problem attacking snakes including rattlesnakes will learn eventually that it will be injured or in some cases die as a result of its behavior. However it is much more humane if you place an electronic dog collar on the dog and the next time he begins to worry a snake he receives a jolt of stimulation. He very quickly learns that attacking snakes will result in a very bad experience. Best of all he does not associate the experience with the trainer or handler. He sees the snake as the cause of his discomfort. Next time no yelling or calling the dog is necessary when you hear a rattler announcing his presence nearby. In addition even if the handler is not present the dog wants nothing to do with any snake. This is avoidance training ends the unwanted behavior for good. The electronic dog training collar saves another dogs life.

James Kesel, MS is the publisher of Career in Dog Training website. Providing information on various careers and methods in dog training. The use of an electronic dog training collar is the most humane and effective tool for avoidance training available. Despite what many uneducated people have stated a proplerly used electronic dog training collar does not harm the dog in any way.

Do Computers Get Tired?

A Silver Bullet?

Until recently, I would have dismissed the notion that electronic gunk can accumulate in a machine and cause it to act erratically. But a few months ago my high-speed Internet connection, which is normally rock solid, started getting flaky. I unplugged my cable modem, plugged it back in and voila... things were back to normal.

And since then I've repeated the procedure a few times with good results, whenever I noticed a slowdown in my Internet speed. So I started thinking... maybe electronic devices and appliances really do get tired, clogged with electrons, or whatever. It turns out that there is some good science to support this layman's observation.

Jerrold Foutz is a Scientist with a capital S. There aren't many people alive who know more about how electronic gadgets (especially power supplies) are supposed to work. So you might be surprised to hear that when your computer, microwave, VCR or high-tech coffee pot isn't behaving, his best advice is "just unplug it."

Totally Cosmic, Dude.In a fascinating article on electronics trouble shooting, Foutz talks about something called a Single Event Upset (SEU) that can cause electronic circuitry to malfunction. An SEU can be caused by a power glitch, or a cosmic ray passing through a integrated circuit, and can actually flip the logic state (from 1 to 0 or vice versa) of a circuit. A cascading effect may trigger a hardware lockup or an infinite loop in software.

For lots more technical details, and even some suggestions on how better design can help to prevent this problem, see the full article on Trouble Shooting Electronics.

Of course in the case of computers running complex operating system and application software, other factors may come into play. Sloppy coding practices can result in 'memory leaks' which over time will cause performance to degrade. But from the end user perspective, the problem looks no different than a hardware error caused by cosmic rays.

Fortunately, the solution is the same in both cases: shut it down, turn it back on, and things will be good again... for a while.
