Enhancements of and to cell phone operations are based in whole or in part on determining the location of the cell phone. Systems and methods select and determine locations or areas of importance or relevance, and based on that information and other programmed factors affect or alter the operations of the cell phone. While the systems and methods are illustrated by use of cell phone embodiments and applications, they are equally applicable to virtually any portable or mobile communication device, including for example, wireless laptop computers and PDAs.

Realtime, location-based cell phone enhancements, uses, and applications

A method and apparatus for providing power to e.g., a chargeable device via a radio frequency link. In one aspect, a method of providing power to a chargeable device via radio frequency link comprises generating a substantially un-modulated signal. The method further comprises radiating a substantially un-modulated radio frequency (RF) signal to the chargeable device via a transmit antenna based on the substantially un-modulated signal. The method further comprises powering or charging the chargeable device with power delivered by the substantially un-modulated RF signal.

Method and apparatus for delivering energy to an electrical or electronic device via a wireless link

A method and system for providing power to a chargeable device via radio frequency link are provided. In one aspect, a method of providing power to a chargeable device via radio frequency link comprises generating a substantially unmodulated signal. The method further comprises radiating a substantially unmodulated radio frequency (RP) signal to the chargeable device via a transmit antenna based on the substantially unmodulated signal. The method further comprises powering or charging the chargeable device with power delivered by the substantially unmodulated RF signal.

Method and system for powering an electronic device via a wireless link

A device for receiving wireless power includes a point of reception, wherein the point of reception is positionable in at least a first position and a second position A method for receiving wireless power The method includes the steps of positioning a point of reception in contact with a housing to a first position There is the step of receiving wireless power at the point of reception and providing it to a power harvester in the housing There is the step of converting the wireless power to usable DC with the power harvester There is the step of providing the usable DC to core components in the housing There is the step of using the DC by the core components There is the step of repositioning the point of reception to a second position.

Powering cell phones and similar devices using RF energy harvesting

Tuning and gain control as described for magnetic power systems, including different ways to change the characteristic of transmission and reception.

Tuning and Gain Control in Electro-Magnetic power systems

An apparatus and method for using ambient RF power in a portable terminal are provided. In the charging apparatus, an antenna array receives RF signals left derelict in the air, a rectifier rectifies the RF signals to DC voltages, and a power storage stores the DC voltages as power.
