WIRELESS CHARGING OF TOOLS USING A TOOLBOX TRANSMITTER
First Claim
1. A method for wireless transmission of power to a cordless power tool, comprising:
- connecting a pocket-forming transmitter to a power source;
generating RF waves from a RF circuit embedded within the transmitter;
generating communication signals from a communication circuit embedded with the transmitter;
controlling the generated RF waves and the communication signals with a digital signal processor in the transmitter;
transmitting the power RF waves and communication signals through an antenna connected to the transmitter; and
capturing the RF waves forming pockets of energy in 3-D space at a receiver with an antenna connected to the cordless power tool to convert the power RF waves into a DC voltage for charging or powering a battery of the cordless tool,

Abstract
Configurations and methods of wireless power transmission for cordless power tools are disclosed. Wireless power transmission for charging one or more cordless power tools may include a toolbox with an embedded transmitter capable of emitting RF waves for the generation of pockets of energy; a battery attached or embedded in the toolbox to supply power to the transmitter; a cable that may connect toolbox'"'"'s battery to a suitable external power source for charging; and one or more cordless power tools which may include rechargeable batteries and receivers that may utilize pockets of energy for wireless charging or powering. When the battery in the toolbox is charged to suitable levels, the toolbox can be disconnected from the external power source and carried to an area or location where one or more cordless power tools may receive wireless charging.
