Title: System and method for data retrieval in ac power tools via an ac line cord
Inventor: CROWELL BRIAN R
IPC: B23D59/00
Filed: 2003-07-18
Granted: 2009-02-17
Abstract: An apparatus (10) and method for obtaining data stored in an electronic module (30) within a power tool (18) over a power line cord (16) of the tool (18), and without any disassembly of the tool (18) being required. An interface subsystem (12) applies a high frequency, low power AC input signal to the power cord (16) of the tool (18). A controller (28) within the tool (18) recognizes this signal as an indication that the tool (18) is to be placed in a communications mode. The controller (28) modulates a power switching device used for turning on and off the motor of the tool (18) in such a fashion that current pulses are transmitted over the power line cord (16) back to the interface subsystem (12). The current pulses correspond to tool (18) usage/performance/identification information stored in the electronic module (30) of the tool (18). This information is interpreted by a current reader circuit of the interface subsystem (12) as binary information which is then transmitted to an external computer (13) data logging device for analysis and/or recording.

Abstract: Internal combustion engine and method in which pistons on different rotors (21,22) move relative to each other to form chambers (27) of variable volume in a toroidal cylinder.(26) The pistons (23, 24) move in stepwise fashion, with the pistons on one rotor travelling a predetermined distance while the pistons on the other rotor remain substantially stationary. Fuel is drawn into a chamber as one of the pistons defining the chamber (27) moves away from the other, and then compressed as the second piston moves toward the first. Combustion of the fuel drives the first piston (23) away from the second (24), and the spent gases are then expelled from the chamber by the second piston moving again toward the first. An output shaft (31) is connected to the rotors (21, 22) in such manner that the shaft (31) rotates continuously while the rotors and pistons move in their stepwise fashion.
