摘要： This disclosure relates to the instant method and system for controlling the interconnecting of a plurality of local communications networks. A source station and a destination station may respectively be adapted to be coupled to at least one communications channel of a communications path, which path includes a plurality of channels, each channel being assignable to at least one of a plurality of local data networks. The respective stations are adapted to determine the home network of the other respective stations with which the respective stations may communicate. Broadly, a source station, which has a message to transmit to a destination station, determines the home network of the destination and couples a first source receiver and a source transmitter to the home network of the destination for transmitting a packet from the source to the destination. A first packet may be transmitted when the source station acquires access to an idle channel of the destination home network. Further packets may be transmitted, not on the destination home network, but rather on the source home network. The source transmitter may be decoupled from the destination home network (if already so coupled) and may be coupled to the source home network for such further packet transmission.

摘要： A light pen which includes a transparent rod at its pointing end through which light is directed to a photodetector that is fixedly positioned within the light pen. The rod is spring loaded and axially slidable in response to applied pressure, resulting in different light intensities being applied to the photodetector and further resulting in an output voltage generated by the photodetector that is directly related to the applied pressure.

摘要： A method and apparatus that employ precomputed line profiles to draw lines on a raster scan terminal with mostly horizontal or vertical "brush strokes" that develop the desired line profiles. The precomputed line profiles relate mostly to the slope of the drawn lines and to the position of the drawn lines between adjacent pixels on the raster scan terminal in the direction of the "brush strokes". A relatively small number of precomputed values is required, permitting the apparatus to operate at the low resolution of the raster scan and be driven advantageously by a look-up table. This results in a very fast operation of the system while leading to pleasing results. The method also takes into account corners and end-of-line conditions to avoid very abrupt and unnatural looking end points.

摘要： An arrangement for butt coupling of waveguide electrooptic plates to form a crossbar switch. The arrangement includes a stack of M splitter plates, each of which routes an injected optical signal to one of N outputs, and a stack of N combiner plates, each of which routes the signal of a selected one of M inputs to a common output. The stack of splitter plates is rotated with respect to the stack of combiner plates and the output signal ports of the splitter plates are coupled to the input signal ports of the combiner plates, so that each output of an splitter plate is connected to a different combiner plate. Within each splitter plate there is a fan-out network of waveguide electrooptic couplers and each coupler, under electric control, routes signals from one input to either one of two outputs. With j levels of such interconnected couplers 2.sup.j output are developed. The combiner plates have an identical architecture but with a signal flow in the reverse direction. Butt coupling of the splitter and combiner plates is achieved by employing splitter and combiner plates of a different crystal cut, by interposing polarization rotation means between two stacks, or by including polarization rotation means within the splitter plates, the combiner plates or both.

摘要： A method of transmitting digital signals (DI) in frames which include a stuffing field between nodes (N) in a network, each node having a buffer and a local clock for producing local clock signals (CLK2). The method includes the steps of extracting clock signals (CLK1) from the digital signals (DI), writing the digital signals into a buffer at the extracted clock signal (CLK1) rate, reading the digital signals from the buffer including reading the content of the stuffing field in order to add or substrate stuffing bits therein in order to compensate for differences in frequencies between the local and extracted clock signals (CLK1, CLK2), and controlling the adding or subtracting of stuffing bits so that the length of the stuffing field is within predetermined limits.

摘要： The generation of individual moments of an image is advantageously achieved by generating a plurality of filtered signals in which each filtered signal is a linear combination of individual ones of the desired moments rather than the actual moment themselves. These filtered signals are obtained by passing the image signals through a series of single pole digital filters arranged as a matrix of filters. Each moment is formed at the end of an image frame by dematrixing the filtered signals. An illustrative embodiment uses repeating circuit patterns so that it can be easily integrated onto a circuit chip.
摘要翻译：图像的单个时刻的产生有利地通过生成多个滤波信号来实现，其中每个滤波信号是期望时刻中的个别时刻的线性组合，而不是实际时刻本身。这些滤波信号是通过将图像信号通过布置为滤波器矩阵的一系列单极数字滤波器来获得的。通过对滤波后的信号进行反矩阵分析，每一时刻都在图像帧的末尾形成。示例性实施例使用重复电路图案，使得其可以容易地集成到电路芯片上。
