Filed:
Mar 14, 2008
Appl. No.:
12/048529

International Classification:
H04B 7/00
US Classification:
455522
Abstract:
A method and a system include a converter configured to convert received radio frequency signals to a direct current (DC) signal to provide power to at least a portion of a receiver. A received radio frequency signal can be associated with a plurality of carrier frequencies within a specified frequency band and time period. The received radio signals can have a total power level above a threshold power level. In some embodiments, the total power level can be above a threshold power level and below a pre-determined power level. Multiple converters can be used. Each converter can correspond to a subset of the carrier frequencies and/or to the carrier frequencies of different specified frequency bands. A combiner can combine the DC output from the converters into a single DC signal. The receiver can communicate data via a data carrier frequency associated with the carrier frequencies used for wireless power transfer.

US Classification:
323282, 323284
Abstract:
An apparatus includes a first converter module, a second converter module, and a sensor module. The first converter module converts a wireless power associated with an electromagnetic wave to a first DC voltage. The first converter module can include, for example, a Villiard cascade voltage multiplier, a precision rectifier, or a full-wave bridge rectifier. The sensor module monitors the first DC voltage. The second converter module converts the first DC voltage to a second DC voltage that is larger than the first DC voltage. The second converter module is enabled by the sensor module when the first DC voltage is above a first threshold voltage. The second converter module is disabled by the sensor module when the first DC voltage is below a second threshold voltage that is lower than the first threshold voltage. The second converter module provides power to a load based on the second DC voltage.
