    摘要： A simplified MEMS optical display device driven by electrostatic forces and associated arrays are provided for. The optical display device includes an optically transparent substrate, an optically transparent fixed electrode disposed on the substrate and a pigmented translucent film disposed on the substrate. A moveable optical shutter is affixed to the substrate and is generally aligned with the fixed electrode and the pigmented translucent film. The moveable optical shutter comprises an electrode element and a biasing element. In addition, a fixed portion attached to the substrate and a distal portion adjacent to the fixed portion defines the optical shutter. When an electrostatic voltage differential is established between the fixed electrode and the optical shutter electrode element the distal portion of the optical shutter will move to controllably regulate the pigmentation of an optical signal.

    摘要： A sample analysis device is provided, the device comprising a frame adapted to accept at least one analysis apparatus, with each analysis apparatus having an analysis distance associated therewith. A eucentric goniometer is operably engaged with the frame and is adapted to eucentrically support a sample at a eucentric point within a reference system defined by the eucentric goniometer. The reference system of the eucentric goniometer is independent of the analysis distance. An axial adjustment device is operably engaged with at least one of the frame and the eucentric goniometer and is configured to coincidentally position the eucentric point and the analysis distance for the respective analysis apparatus. An associated device and method are also provided.

    摘要： An electromechanical device includes a first frame having a first aperture therein, a second frame suspended in the first frame wherein the second frame has a second aperture therein, and a plate suspended in the second aperture. A first pair of beams support the second frame along a first axis relative to the first frame so that the second frame rotates about the first axis. A second pair of beams supports the plate along a second axis relative to the second frame so that the plate rotates about the second axis relative to the frame. The first and second axes preferably intersect at a 90.degree. angle. A first actuator provides mechanical force for rotating the second frame relative to the first frame about the first axis. A second actuator provides mechanical force for rotating the plate relative to the second frame about the second axis. Accordingly, the plate can be independently rotated relative to the first axis and the second axis. Related methods are also disclosed.

    摘要： A noise suppressor includes an input transducer and an output transducer adapted to be located in an ear canal. A housing is provided to support the transducers in the ear canal, and the housing provides an acoustically unobstructed passage from the entrance of the ear canal to the ear drum. The input transducer generates electrical signals in response to sound pressure waves entering the ear canal, and a portion of the electrical signal is processed to generate an inverse noise signal which is applied to the output transducer. Accordingly, the output transducer produces inverse noise pressure waves in order to reduce an undesired noise portion of the sound pressure waves reaching the ear drum. The sound pressure waves also reach the ear drum without significant alteration.

    摘要： A method for pretreating a solder surface for fluxless soldering is disclosed. The method uses a noble fluorine gas to remove surface oxides from solder surfaces, without the use of external stimulation. A noble fluorine gas is suffused across the solder surface to reduce or eliminate or chemically convert the surface oxides. The process can take place at atmospheric pressure and room temperature. A simple belt driven transport may be used to move the parts past a nozzle which emits the vapor in a system similar to a conventional solder reflow machine.

    摘要： A field effect transistor includes a pair of buried centroid regions in a semiconductor substrate at a predetermined depth from the substrate face and having a doping concentration opposite the source and drain regions. A gradient region surrounds each of the pair of buried centroid regions. The gradient regions have decreasing doping concentration in all directions away from the associated centroid region. Source and drain extension regions may also be provided. The buried centroid/gradient regions operate to screen charge on the source and drain regions facing the channel to prevent this charge from interacting with the channel. Short channel effects are thereby reduced or minimized. The threshold voltage of the device can also be adjusted without the need for threshold adjusting implants. The buried centroid/gradient regions and source and drain extension regions may be fabricated in a self-aligned process using the gate and gate sidewall spacers as a mask.
