| 20110264945 | Power supplying and data transmitting method for induction type power supply system - A power supply and data signal transmission method used in an induction type power supply system consisting of a power supply module and a power-receiving module for transmission of electrical energy and data signal is disclosed. The microprocessor of the power supply module scans the resonant point of the power supply coil to send a segment of energy for recognition of a feedback signal from the power-receiving module and then starts providing power supply after receipt of the feedback signal, and then runs further signal modulation, transmission, data decoding and other follow-up steps, achieving transmission of electrical energy and data signal wirelessly. | 10-27-2011 |
| 20090267561 | INDUCTION TYPE POWER SUPPLY DEVICE - An induction type power supply device includes a power supply base unit having a connection interface connectable, an oscillator circuit for producing an AC signal upon connection of the connection interface to an electric outlet, a driver circuit for amplifying the AC signal and a primary inductor for obtaining a resonant frequency and releasing the AC signal, and an attached induction device placed on the power supply base unit and having a secondary inductor for receiving the AC signal from the primary inductor by means of magnetic induction, a rectifier filter circuit for converting the AC signal into a DC power supply, a power management circuit for regulating the DC power supply subject to a predetermined voltage and current value and a connection device for the connection of an external mobile electronic apparatus and for outputting the regulated DC power supply from the power management circuit to the connected external mobile electronic apparatus. | 10-29-2009 |
