Electronic system for monitoring pneumatic tool performance
First Claim
1. An electronic system for generating signals representative of the performance of a pneumatic tool during one or more work cycles wherein said pneumatic tool includes a working cylinder and gaseous actuating fluid contained therein, said electronic system comprising:
- means to generate a signal in real time representative of the actuating gaseous fluid pressure in the work cylinder of said pneumatic tool;
first means to operate at times on said real time pressure signal only over a selected time portion of each of said work cycles for generating a signal representative of the energy developed in said pneumatic tool during said time portions; and
second means to operate at times on said real time pressure signal only over a selected time portion of each of said work cycles for generating a signal representative of the friction developed in said pneumatic tool during said time portions.

Abstract
An electronic system to monitor the performance of a pneumatic impact forming tool is disclosed. A signal is generated in real time representing the actuating pressure of the pneumatic tool. Electronic functions operate on the real time pressure signal over a predetermined time portion of each work cycle of the pneumatic tool to generate signals representative of the energy and friction developed in the pneumatic tool during the predetermined time portions of one or more work cycles. The electronic system additionally provides a count of the number of work cycles generated by the pneumatic tool during operation thereof.

7. An electronic system for monitoring the performance of a pneumatic tool, said electronic system comprising:
-
means to generate in real time a signal representative of the actuating gaseous fluid pressure in said pneumatic tool; first means goverend by said pressure signal to generate a train of pulses with a pulse rate correspondingly proportional in time to the magnitude of said real time pressure signal; second means governed by the magnitude of said pressure signal to generate a time duration pulse during each work cycle of said pneumatic tool; a counter governed by said time duration pulse signal to generate consecutive counts wherein each consecutive count corresponds to a pulse of said pulse train generated by said first means; third means to generate a train of pulses with a predetermined constant pulse rate; and an accumulator governed by a selected one of said first and third means to accumulate only those counts generated by said counter which are concurrent with the pulses generated by the selected one of said first and third means during said time duration pulse wherein the count accumulation in said accumulator is representative of the performance of said pneumatic tool. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
