摘要： A process and apparatus for measuring and regulating the variable pressure furnace gas chemistry is described. The method makes use of mass spectrometer measurements, in the preferred form of the invention, in which gas species percent composition is obtained quantitatively independent of total furnace pressure variation. Using such a real time measurement capability, active control of batch process furnace operations is possible by intrinsic measurement of the part outgassing rather than by assumption of batch part status as a function of extrinsic parameters such as temperature and total pressure. Thus, by a combination of batch process temperature ramp control and variable admittance of suitable gas into the furnace, uniform batch processing is possible by closed loop control, due to renormalization of furnace residual gas chemistry from day to day drift and from batch part chemistry variation. Quantitative measurements of the variable residual pressure is made possible by adjusting in real time the throughput into the mass spectrometer indpendent of the total pressure variation in the furnace. These measurement means also make possible the real time determination of sinter part densification in vacuum furnaces by measurement of the part outgassing attenuation during pore closure.

摘要： A smart array comprised an array of polymer grid triodes arrayed with a common polymer grid. In a preferred embodiment it is embodied as a conducting polymer device which provides local gain adjustment for video display such that the entire sensor dynamic range available, typically more than 16 bits in the infrared detector case, can be utilized locally to solve the intra-scene contrast problem. The array of polymer grid triodes with common grid can be utilized to process the image in analog form directly on the focal plane. Alternatively, the array of polymer grid triodes with common grid can be utilized to process the image after analog to digital conversion and integrated directly into the display.

摘要： A system, apparatus and methods are disclosed for the spatial and temporal processing of time dependant array data using analog signal processors. In one embodiment, a programmable array of switched capacitors is used to provide tunable parameters for controlling the desired processing of input data streams. The switched capacitor implementation of a spatial filter provides a massively parallel device that can be programmed to perform isotropic and spatially-oriented anisotropic filtering with low power demands. The system further includes the ability to combine differently filtered output streams with independent multiplicative weights. In another embodiment, the nonlinear spatio-temporal motion energy of a two-dimensional image stream data is computed. The spatial-temporal filter is able to combine multiple analog filters, both spatial and temporal, to perform complex spatial-temporal filtering operations implemented by Gaussian kernel filtering chips. It enables the use of analog spatial-temporal filtered data provided by the chip for computing scene motion energy.

摘要： A channel is formed in the body of a machine tool holder, this channel extending to the area where the tool is working on the workpiece. A pneumatic flow away from the tool is established by means of a vacuum source connected to the channel. A pressure transducer is connected to the channel so that it is capable of sensing the pneumatic pressure therein. The transducer produces an electrical output in accordance with the sensed pressure, this electrical output being suitably processed to provide a control signal capable of shutting down the operation of the machine tool and simultaneously providing a warning signal. With the incipient failure of the tool, as evidenced by either excessive heating of the tool or the production of filamentary chips from the tool (this occurring when the outer hardened coating of the tool wears off), an abrupt change in the pneumatic pressure in the channel occurs resulting in the generation of a control signal which both shuts down the machine tool operation and provides a warning signal to the operator. A complete failure, such as breakage of the tool, will also cause a pressure change producing such a control signal.
摘要翻译：通道形成在机床夹具的主体中，该通道延伸到工具在工件上工作的区域。通过连接到通道的真空源建立远离工具的气流。压力传感器连接到通道，使其能够感测其中的气动压力。传感器根据感测的压力产生电输出，该电输出被适当地处理以提供能够关闭机床的操作并同时提供警告信号的控制信号。随着工具的初期故障，如通过工具的过度加热或从工具生产丝状切屑所证明的（当刀具的外部硬化涂层磨损时，会发生这种情况），气动压力的突然变化通道发生导致产生控制信号，这两者都关闭机床操作并向操作者提供警告信号。完全失效，如工具破损，也会导致产生这种控制信号的压力变化。
