Wireless Power Chargers About to Hit Market - very electric toothbrush

Since the advent of home electronics, wires and cables have been the reality of consumer equipment.
However, this reality may change soon as some companies continue to make progress in eliminating the wires that tie our gadgets to the wall --
And between each other.
Powercast in new Pennsylvania
The company says its wireless energy collection solution is not only reliable, but also in line with the FCC-
John Shearer, founder and chief executive of Powercast, said the company had been approved but was also ready to debut on millions of small devices by the end of 2008.

China patent and innovation center. The technology?
Radio waves, the same technology drives the phone and your FM dial.
Short-selling promises
A series of wireless technologies such as ultra-broadband, wireless USB and wireless high speed
A defined interface (WHDI) for transferring data from one device to another, or a method for powering these devices, such as induction-
Or now, RF )-
Families in the future look more and more cordless.
"Basically, we have developed a chip on the transceiver and receiver side that can efficiently transmit RF energy," said Keith Kressin, executive vice president of sales and marketing at Powercast . ".
While Kressin admits that using RF energy to power electronics is not a particularly new idea, he says his company's patented approach is unique
According to the company, this is 70% higher than the traditional method (usually 10%.
Because radio waves are actually energy, they have been used to send and receive mobile phones, TVs, radios and wireless networks.
He explained that the Fi signals every day.
These waves travel in all directions until they reach an antenna tuned to the appropriate frequency.
Powercast's wireless power platform broadcasts low levels using the "Powercaster" transmitter circuit running on traditional currents
A power radio signal of a predetermined frequency.
Smaller "power harvester" receiving circuit-
It can embed any lowpower device —
According to Kressin, this energy is then used to charge and even replace the battery of the device.
The Powercast solution enables the use of a wider range of RF spectrum areas (900-MHz band.
While not necessarily a replacement for traditional Chargers, the technology will be able to "trickle-charge" various electronic devices over a period of time so that their energy will not be completely drained.
As with the traditional AM/FM radio, the closer the tower that transmits the signal, the better the reception effect.
Powercast's wireless platform runs on a similar principle.
According to the company, in this case, the wireless power platform can harvest a few milliwatts of energy in the range of 1 m from the power supply.
According to Kressin, this is enough to charge about half of a depleted cell phone battery overnight.
Kressin said the solution is also ideal for devices with small batteries such as watches, hearing aids, wireless keyboards, mouse and game controllers, all of which can be continuously charged.
However, the charging capacity of the Powercast platform is limited.
Larger devices such as laptops cannot use the company's solutions simply because they require too much power.
In fact, the size limit now seems to be in the cell
Company executives said the level of telephone charges effectively.
In this year's Powercast demo at CES, two prototype lamp poles with Philips led were presented using the company's new technology.
According to Kressin, Philips will be the first company to ship with a wireless power platform later this year.
"They are developing a lighting application that you can do with small LEDs," he said . ".
"You're just charging in this form, not charging.
But I'm following up on about 20 major categories of equipment that our solution works.
We are also talking to many companies that are now interested in developing prototypes.
"While a spokesman for Philips did not immediately comment on the upcoming lighting product, Govi Rao, vice president and solid-general manager of the company
In a recent interview with Business 2, National Lighting said, "This technology may completely change our understanding of electricity ". 0 magazine.
Of course, Powercast is not the only company dedicated to wireless energy transmission. Arizona-
WildCharger, which showed its technology at CES this year, is currently developing a series of charging boards using so-called direct sensing, by direct contact between the smaller adapter installed on the device and the charging board itself, power can be transmitted wirelessly.
Induction is basically the same technology for charging electric toothbrushes, and it is well known that the magnetic field used by "inductive coupling" is an inherent part of any current moving through a wire.
When the current passes through the wire, it creates a circular magnetic field around the wire.
This can amplify these magnetic fields by bending the wires into coils.
The more coils the coil is made, the greater the magnetic field.
While the pad itself has to be plugged into the wall socket, it will provide a steady stream of power to the equipment placed anywhere on it.
WildCharger says its 15x40 cm pads will be at 90-
Watt capacity, and will be able to charge large devices such as laptops, blackberries and mobile phones at the same time.
Another solution comes from Fulton Innovation and its new ecological technology.
ECoupled also uses intelligent sensing, but is designed to be embedded in circuits of ordinary homes and everyday objects such as countertops, cabinets, bags, car dashboards and consoles, the company said.
The circuits will then communicate with the receiving coils, which can be built into common consumer electronics such as laptops, mobile phones, music players and gaming devices.
When someone places an eCoupled device on an eCoupled --
On the prepared surface, the base will automatically identify the relationship between the device itself and the base and compensate and adjust according to its charging needs.
Like all wireless communication technologies, consumers can expect to see a variety of free wireless charging solutions available in the coming years.
Kressin said that it is likely that Powercast's wireless energy solutions will not compete with other technologies such as induction, but will be used with them.
"I really think our Powercast solution is a complement to inductive charging," Kressin said . ".
"The advantage of induction is that it is more efficient and can transmit more power.
This is your solution if you're going to charge something bigger, like a laptop.
"But induction also has its drawbacks," Kressin said.
"In a very short distance, the power will be turned off. .
The size, cost and weight of the coils used in induction are prohibitive.
I definitely don't want to say we are better, but for apps that use small batteries, of course we think we have an answer.
