Hanspeter Widmer

Hanspeter Widmer, Solothurn CH

Patent application numberDescriptionPublished
20090127937Wireless Power Bridge - A wireless power bridge that allows magnetic transmission of energy across a solid barrier such as a wall. A circuit is described for controlling the operation.05-21-2009
20090212636Wireless desktop IT environment - A wireless powered desktop system.08-27-2009
20100117596WIRELESS HIGH POWER TRANSFER UNDER REGULATORY CONSTRAINTS - Improved battery-charging system for a vehicle. Primary and secondary coils are located in places where the vehicle can receive power from the primary coil by pulling into a parking space, for example. The parking space may have a coil embedded in the ground, or may have an array of coils embedded in the ground. A guidance system is disclosed. Fine positioning is also disclosed. The secondary coil in the vehicle can also be raised or lowered to improve coupling.05-13-2010

Hanspeter Widmer, Wohlenschwill CH

Patent application numberDescriptionPublished
20080211320WIRELESS POWER APPARATUS AND METHODS - Wireless energy transfer system. Antennas are maintained at resonance with High Q. Techniques of maintaining the high-Q resonance matching are disclosed.09-04-2008
20090058189LONG RANGE LOW FREQUENCY RESONATOR AND MATERIALS - Transmission of power at low frequencies, e.g. less than 1 MHz. The power can be transmitted in various ways, using different structures included stranded wire such as Litz wire. The inductor can also use cores of ferrites for example. Passive repeaters can also be used.03-05-2009
