Title: Impact tool battery pack with acoustically-triggered timed impact shutoff
Inventor: CARNEY STEVEN C
IPC: B25F5/00
Filed: 2002-07-15
Abstract: An electrically powered impact tool has a removably mountable battery pack which includes an acoustic detection circuit for detecting sounds generated by the impact mechanism in use and, in response to such detection, starts an adjustable time period, at the end of which a relay is actuated for disconnecting the battery of the battery pack from the tool motor for a predetermined time period. This serves as a torque-limiting mechanism where the tool is a torque-applying tool. The time period is adjustable by a dial on the battery pack housing and the control circuitry may be selectively powere d through a switch on the battery pack housing.

Title: Feedback circuit and method of operating ballast resonant inverter
Inventor: ALEXANDROV FELIX I
IPC: H05B41/285
Filed: 2004-06-25
Abstract: A ballast resonant inverter with a self-oscillating driver IC powers and dims a gas discharge lamp. A feedback circuit automatically adjusts IC oscillator frequency for safe and stable inverter operation above the resonant frequency following changes in the resonant load. The feedback signal is derived from resonant inverter output voltage, by attenuating, programmed phase shifting and injecting the resulting signal in a timing circuit of the IC. The feedback circuit includes an active inverter circuit or passive RC phase boosting networks coupled in series. Phase control of the feedback signal by variable RC networks is used in transient modes of ballast-lamp operations.
