摘要： A video signal processor, particularly for use in identifying light source position, in which a video signal stream from an image detector is processed directly on a substrate using charge coupled device stored image transfer technology. The video signal is clocked through an array of charge coupled devices in a plurality of closely adjacent channels on a single semiconductor chip in such manner that the pattern of signals stored on the chip in the region of the adjacent channels corresponds to the light source image on the detector. Video signal processing is shared between the chip and external electronics to provide an indication of signal strength (acquisition), signal background, and signal centroiding in both horizontal and vertical axes. Much of the signal processing is provided directly on the chip by segmenting and intercoupling the charge coupled device electrodes in a predetermined pattern. There results a reduction in the amount of interconnection, external electronics and the spatial distribution of the video signal that improves the system immunity to environmental noise and limits weight aloft.
摘要翻译：特别是用于识别光源位置的视频信号处理器，其中使用电荷耦合器件存储的图像传输技术在基板上直接处理来自图像检测器的视频信号流。视频信号通过在单个半导体芯片上的多个紧密相邻的通道中的电荷耦合器件的阵列进行计时，以使存储在相邻通道区域中的芯片上的信号的模式对应于光源图像检测器。视频信号处理在芯片和外部电子设备之间共享，以提供在水平轴和垂直轴上的信号强度（采集），信号背景和信号质心的指示。信号处理的大部分通过以预定图案分段和互耦合电荷耦合的器件电极而直接在芯片上提供。结果导致互连量，外部电子设备和视频信号的空间分布的减少，这提高了系统对环境噪声的抵抗力并且在高处限制了重量。

摘要： A gimballed vibrating wheel gyroscope for detecting rotational rates in inertial space. The gyroscope includes a support oriented in a first plane and a wheel assembly disposed over the support parallel to the first plane. The wheel assembly is adapted for vibrating rotationally at a predetermined frequency in the first plane and is responsive to rotational rates about a coplanar input axis for providing an output torque about a coplanar output axis. The gyroscope also includes a post assembly extending between the support and the wheel assembly for supporting the wheel assembly. The wheel assembly has an inner hub, an outer wheel, and spoke flexures extending between the inner hub and the outer wheel and being stiff along both the input and output axes. A flexure is incorporated in the post assembly between the support and the wheel assembly inner hub and is relatively flexible along the output axis and relatively stiff along the input axis. With this arrangement, the wheel assembly is gimballed on the support. More particularly, the post flexure flexes in response to the output torque; whereas, the spoke flexures allow for the rotational vibration in the first plane. Also provided is a single semiconductor crystal fabrication technique which allows for improved device manufacture.

摘要： A double gimbal micromachined gyroscopic transducer is provided in a substrate having a pit extending downwardly from a top surface of the substrate. A gyroscopic transducer element suspended above the pit comprises an outer sense gimbal plate integral with the substrate, coupled to the substrate by a pair of flexible elements attached to opposite ends of the plate. The flexible elements are axially aligned to permit oscillatory motion about a sense axis passing through the flexible elements. The gyroscopic transducer further includes an inner drive gimbal plate integral with and interior to the sense gimbal plate. The drive gimbal plate is coupled to the sense gimbal plate by a second pair of flexible elements along an axis orthogonal to the first pair of flexible elements. The drive gimbal plate also includes a balanced mass generally centrally located on the drive gimbal plate. Also included are drive and sense electronics, for energizing the drive gimbal plate to oscillate about the drive axis, and for sensing any movement of the sense gimbal plate indicative of an angular rate about an input axis. The sense electronics includes a sense electrode disposed so as not to be in close proximity to and interfere with free oscillatory motion of the drive gimbal plate.

摘要： A monolithic, micromechanical vibrating string accelerometer with a trimmable resonant frequency is fabricated from a silicon substrate which has been selectively etched to provide a resonant structure suspended over an etched pit. The resonant structure comprises an acceleration sensitive mass and at least two flexible elements having resonant frequencies. Each of the flexible elements is disposed generally colinear with at least one acceleration sensitive axis of the accelerometer. One end of at least one of the flexible elements is attached to a tension relief beam for providing stress relief of tensile forces created during the fabrication process. Mass support beams having a high aspect ratio support the mass over the etched pit while allowing the mass to move freely in the direction colinear with the flexible elements. Also disclosed is a method for fabricating such an accelerometer with high aspect ratio tension relief and mass support beams.

摘要： A method of fabrication of micromechanical devices enables the production of large area micromechanical transducer structures which are symmetric, stress balanced structures relatively devoid of geometric distortions. Micromechanical transducer structures are fabricated implementing processes and physical characteristics which overcome the unbalanced stresses occurring in high concentration diffusion planar structures that cause problematic geometric distortions that restrict physical size. Large increases in the practical size of micromechanical devices which may be fabricated are achieved while permitting greater depths of structural features, without the resultant concentration and stress distortions. Multilevel, balanced stress structures can be created which are of varying geometries at each level to produce a "sculpted" structure.

摘要： A semiconductor chip gyroscopic transducer is disclosed in which a semiconductor element is supported in an outer element by a flexible linkage system which is in turn supported in a frame of semiconductor material by another flexible linkage system which permits the element to vibrate about two axes relative to the frame. Balanced torque forces are provided by a system of buried and bridge electrodes. The stress and tension resulting from doping of these elements are released by a flexure beam. The inertial mass of the inner element is balanced by formation in a central pin and on-chip electronics avoids the capacitive loading effects of long runs from high impedance sources.Flexure footings are intergrated with the structure adding stability to flexures connecting the supported gyroscopic resonator element to the supporting structure, offsetting a rippling effect inherent in the oxide structure. Flexure grooves provide selective stiffness in the flexure. The bridge electrodes are additionally electrically isolated for electrical compatibility with gyroscope electronics.

摘要： A device, method and process of fabricating an interdigitated multicell thermo-photo-voltaic component that is particularly efficient for generating electrical energy from photons in the red and near-infrared spectrum received from a heat source in the near field. Where the absorbing region is germanium, the device is capable of generating electrical energy by absorbing photon energy in the greater than 0.67 electron volt range corresponding to radiation in the infrared and near-infrared spectrum. Use of germanium semiconductor material provides a good match for converting energy from a low temperature heat source. The side that is opposite the photon receiving side of the device includes metal interconnections and dielectric material which provide an excellent back surface reflector for recycling below band photons back to the emitter. Multiple cells may be fabricated and interconnected as a monolithic large scale array for improved performance.
