ABSTRACT:
A system for inductively coupling power and data to a portable electronic device. A portable device, such as a personal digital assistant, is powered or recharged via an inductive link between the device and a support unit, thereby eliminating the need for cabling or other connections therebetween. The same inductive link is also used to transfer data signals between the device and a second electronic device, for example, a conventional desktop computer. The support unit includes a primary winding of a transformer, a power amplifier and a modulator. The portable device includes a secondary winding connected in parallel with the input of a rectifier, the output of which is connected to a battery charging circuit, and to a modem, which is further connected to the device microprocessor. Placement of the device on the support unit effects the inductive coupling when the primary and secondary windings are in proximity to one another.
