Patent CA-2491743-A1 (CA)
Inventor: STATNIKOV EFIM S
IPC: C21D7/04
Filed: 2003-04-17
Abstract: Metallic workpieces of diverse shapes having work surfaces (13) which are deformed at the surface and adjacent sub-surface layers by surface impact from ultrasonic transducers (11) employing freely axially moving impacting elements (12) propelled and energized by a transducer oscillating surface vibrating periodically (10) at an ultrasonic frequency (14). The impacting elements are propelled in a random aperiodic and controlled impact mode at different phases of the periodic oscillation cycles. The transducer may be portable and provides a series of mechanically interconnected stages having mechanical resonances harmonically related as a multiple of the primary ultrasonic frequency and have matched stage resistances under instantaneous loading when the impact elements are driven by the transducer oscillating surface into the surface of the workpiece. This mode of operation produces Q-factor amplification of the input ultrasonic power oscillator energy at the impact needles and high propulsion velocities making it possible to machine metallic workpiece bodies to greater depths for compressing the metal to increase compressive strength of the work surfaces and ultimate material strength of the workpiece. The machining is done at ambient temperatures.

Title: Control of peaking of laser driver current to improve eye quality
Inventor: WEBER ANDREAS
IPC: H04B10/08
Filed: 2003-11-06
Abstract: An optical transceiver module (Fig. 3) having digital control of laser current peaking is disclosed. The optical transceiver module comprises a controller and integrated postamplifier/laser driver (Fig. 3), which are included on a printed circuit board disposed in the module. Transmitting (14) and receiving optical sub-assemblies (47) are also disposed in the module. A digital signal interface (50B) interconnects the controller with the integrated postamplifier/laser driver. Digital control signals produced by the controller are transmitted via the digital signal interface to the integrated post-amplifier/laser driver, where they are converted to analog control signals.  The analog control signals are forwarded to control components (48) responsible for governing the electrical current supplied to the laser of the transmitting optical sub-assembly. The laser current is intermittently peaked by the control signal in order to hasten the transition from light to no-light emission, thereby improving laser response and performance.
