low power devices wireless

and Bluetooth technology for wireless mobile devices, the beautiful appearance of the spinal cord, is not it? Some manufacturers have a new technology that allows a smaller cell phone and other wireless devices do not download. This is the "Buck Rogers" or what?

Powercast (Pittsburgh, Pa.) said he is a power solution for wireless handhelds. The technique is reliable, the FCC (security), and ready for shipmentPowercast this year, the technology used to transmit RF waves is entitled to use the device. According to Keith Kressin, executive vice president of sales and marketing, technology, efficiency (compared to the amount of energy actually used in the transmission to 2 watts each for more than 1 watt of power) is greater than 50%.

Portable PA Systems

The efficiency is inversely proportional to the distance between the transmitter and receiver. Less than 3Leg, the return of approximately 70%. Energy is wasted on frozen food, heat, uh, ... No, just kidding should be used.

Powercast uses the mark in the 900 MHz band, the movement of energy from the machine age. Other assets in the same group should not interfere with the operation, yes, do not consume energy receiver Powercast around this frequency and scope of the case. However, this technique is not completely replace the conventional battery charger for all devices. Thisable to "float" for a while, so that the rate of energy loss has slowed, at least for low power devices.

The concept behind the product is not new Powercast. The problem is that the reflected power is transferred in this way the different surfaces and fluctuations of the signal. Powercast solution for a client, like a radio tuned to different frequencies at once.

The transfer of power more than a few watts at a distance of 3 feet (maximum capacity15 watts). That should be enough to charge most phones have a 50% to 12 hours. This is ideal for mobile phones, keyboard / mouse wireless medical implants such as pacemakers and other small appliances. The technology is not yet enjoy the support of a higher power devices such as laptops that are used to consume more energy than the electricity grid can be expressed.

Phillips is the first product on the market PowercastSystem by the end of the year. The first product of lighting a stick of light, low energy consumption. For this application, there is no battery on board, but follow the electricity supply system Powercast. "When seven months ago when this was possible, I asked said, you dream?" You smoke what? "Says Govi ​​Rao, vice president of Solid-State Lighting Phillips.

Powercast current system costs less than $ 10 in production.In many devices will Powercast solution less costly than the implementation of a battery, and is also environmentally friendly "green."

An alternative technology Powercast and inductive loads. If you have an electric toothbrush, Sonicare, you already have an inductive charging system. inductive system is actually a transformer, an inductive load, but "less", but wirelessly. This system requires close collaboration between the magazine and Structure, since the yield decreases sharply as the distance nothing but very short. Powermat is one of the companies developed a system in the form of a pillow, under the group would be needed to support stronger and more capable devices like laptops. The system is currently able to output about 90 watts.

The Wireless Power Consortium was formed to develop this year in Hong Kong to set standards, so that the charging process> Systems and the ability to communicate with customers. This is important because the tax only if the energy efficiency of equipment available and adequate. This improves security and efficiency. Logitech is one of the founding members of the consortium, National Semiconductor, Philips Electronics, Sanyo, Shenzhen Sang Fei Consumer Communications and Texas Instruments.
