Power hand tool with data collection and storage and method of operating
First Claim
1. A hand power tool comprising:
- a housing;
a motor within the housing; and
a tag mounted on the housing, the tag includinga first antenna for harvesting energy from an electromagnetic field associated with the motor,a microprocessor configured to operate using the harvested energy,a memory including stored commands which, when executed by the microprocessor, cause data associated with a sensed condition of the hand power tool to be stored within the memory, anda second antenna for coupling with a radio frequency identification (RFID) reader and for transmitting the data stored within the memory to the RFID reader.

Abstract
The invention provides a system and method of monitoring at least one operating characteristic of a hand power tool. In one embodiment, a hand power tool includes a housing, a motor within the housing and a tag mounted on the housing. The tag includes a first antenna for harvesting energy from an electromagnetic field associated with the motor, a microprocessor configured to operate using the harvested energy, a memory including stored commands which, when executed by the microprocessor, cause data associated with a sensed condition of the hand power tool to be stored within the memory, and a second antenna for coupling with a radio frequency identification (RFID) reader and for transmitting the data stored within the memory to the RFID reader.
