Abstract: An energy-efficient method and system for processing target material such as microstructures in a microscopic region without causing undesirable changes in electrical and/or physical characteristics of material surrounding the target material is provided. The system includes a controller for generating a processing control signal and a signal generator for generating a modulated drive waveform based on the processing control signal. The waveform has a sub-nanosecond rise time. The system also includes a gain-switched, pulsed semiconductor seed laser for generating a laser pulse train at a repetition rate. The drive waveform pumps the laser so that each pulse of the pulse train has a predetermined shape. Further, the system includes a laser amplifier for optically amplifying the pulse train to obtain an amplified pulse train without significantly changing the predetermined shape of the pulses.

Abstract: A rotary bearing includes concentric radially spaced-apart inner, intermediate and outer rings whose opposing surfaces define inner and outer ball tracks. An inner array of balls roll along the inner track and an outer array of balls roll along the outer track and a viscous lubricant is present between the rings. When the inner and outer rings are angularly reciprocated relative to one another, the intermediate ring is moved intermittently in a selected direction about the rotation axis so that the balls recirculate about the axis and redistribute lubricant along the tracks. In a preferred embodiment, the relative angular excursion of the inner and outer rings is increased periodically beyond a selected maximum angle to effect the advancement of the intermediate ring using the lubricant as a ratcheting mechanism.

Abstract: A system including confocal and triangulation-based scanners or subsystems provides data which is both acquired and processed under the control of a control algorithm to obtain information such as dimensional information about microscopic targets which may be "non-cooperative." The "non-cooperative" targets are illuminated with a scanning beam of electromagnetic radiation such as laser light incident from a first direction. A confocal detector of the electromagnetic radiation is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam of electromagnetic radiation. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem also includes a detector of electromagnetic radiation which is placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors.

Abstract: A digital decorating system for transferring a selected image to a surface of an article includes a thermal printhead, an advancing mechanism for producing relative movement between the printhead and the surface of the article, and a force member for exerting a selected amount of pressure between the thermal line of pixels and the surface of the article. The thermal printhead includes a plurality of energizable heater elements constructed to deliver heat to a thermal line of pixels on a surface of the printhead. The digital decorating system also includes a microcontroller operatively connected to the printhead, the force member and the advancing mechanism to provide control signals selectively delivering heat to pixels of the thermal line and selectively causing the movement thereby thermally transferring, over a two dimensional array of pixels, a two dimensional image to the article surface.
