Lithium Batteries - The Ultimate Energizers

Lithium batteries have proven to be the longest lasting batteries perfect for all the modern electronic devices used commonly. A result of yet another scientific breakthrough, the working of these batteries is based on the lithium technology. Besides having a longer shelf life (of about 15 years) and better power storage capacity, Lithium batteries offer some unique advantages over other batteries of equivalent size. These advantages include:

- Higher longevity in digital cameras (up to 8 times longer)

New Spy Cameras - The Ultimate Body Worn Covert Cameras - Five Models To Choose From

Just about everybody has heard of hidden cameras and has an idea of what they're supposed to do. The latest entry into dumb TV shows is called "What Would You Do?" It places people in precarious situations and preys on passing innocent bystanders to see how they would react. They make no secret about using hidden cameras.

Hidden cameras catch people doing things that they shouldn't be doing such as in the case of a nanny abusing a child; or the case of a business, an employee stealing from a cash register; or in the case of a marriage, a spouse cheating on another spouse. Hidden cameras are so good at catching people like that because they are hidden inside objects that people see on a day-to-day basis. They're so used to seeing them that no one ever suspects they are being recorded.

Electronic Enhancements to Hearing Protection

For pilots and aircraft passengers, ear protection is crucial to reduce the possibility of permanent hearing loss. Repeated exposure to aircraft noise levels can have devastating effects over a range of sound frequencies. To lessen the chances of hearing loss, all aircraft occupants should consider ear protection when traveling by air.

Though a variety of ear protection options exist, perhaps none provides greater protection than electronic noise cancelling (ENC) headphones. Also known as active noise reduction (ANR) technology, aviation ANR headsets provide more than just passive, clamp-over-the-ears sound muffling. ENC technology employs electronic circuitry to supplement the noise-reducing effects of passive ear cups.

ENC technology works by counteracting the effects of aircraft engine sound frequencies. All sounds travel in waves, each frequency possessing its own amplitude and phase. ENC devices emit sound waves of the same amplitude, but inverted phase of the original sound. This results in interference, with the ENC-produced sound wave essentially cancelling out the original sound. ENC headphones are most effective at cancelling lower-frequency sounds, which include the frequency spectrum most commonly produced my aircraft engines and propellers.

Considerations for ENC Headphones

When choosing ENC hearing protection, aviators should consider the variety of options on the market. Unlike passive ear protection, ENC devices require a power source to supply their noise-cancelling sound waves. This power can be supplied either by a portable battery pack or the aircraft's electrical system. For aircraft power, headsets come with a unit that connects to the electrical system through the instrument panel. Battery-powered models have a compact battery module for ENC power.

To Die-For Electronics For the Urban Professional - Anti-Technophobia Gadgets You Simply Must Have

If you are one of those new urban professionals who have yet to feel very comfortable with technology - technophobia as it is called - take comfort in the fact that you are not alone in your fear of all things techie like electronics for the urban professionals. A published study reveals that majority of new company employees might be technophobes in varying degrees.

Disadvantages of Technophobia

However, you have to let go of your fears at some point, preferably sooner than you want, because technophobia exacts a toll on your personal and professional life:

- Your quality of life will be affected. Imagine having to avoid technology when you have to live and work with electronics for the urban professionals! Unless, of course you work in an Amish community, there is simply no easy way of escaping technology nowadays.

DMX Controller For The Ultimate Lighting System

Lighting up a place like a night club to attract Saturday night party goers involves creativity mixed with the comprehensive knowledge of the excellent DMX controller. This is a lighting console device which is capable of generating wonderful visual effect under the hands of a proper lightning programmer. It is a fact known to everyone that lighting of a night club is responsible for the mood of the visitors. The way the lights dance to the audio tracks and the way they flash all across the dance floor make the club far more popular. The controller might operate any lighting device attached to it, but the way the programmer pre-programs the software makes all the difference.

The excellent DMX controller could constantly deliver signals to the attached lighting components. Say a fixture consists of 50 bulbs of different shades set in the ceiling, in a circular form all around the head of the DJ. The DMX controller could be pre-programmed to flash, dip lights in a specific sequence and pattern in a predefined period of time. Consider an example, when the red lights in the inner circle are coded to flash each time the green lights in the external circle flash and made to stay illuminated in the high voltage point for 5 seconds and after that dip to 4 V and shut off after four secs. In this case the DMX controller may immediately transfer the corresponding signals to the roof fixture, as soon as it is programmed.
