摘要： An optical neural network which imitates a biological neural network, to provide an associative and/or pattern recognition function, is made of light emitting elements to represent an input neuron state vector, a correlation matrix which modulates light according to stored vector information, light receiving elements, an accumulator and a comparator to perform a threshold function. A stored vector closest to an input vector can be found from a large amount of information without increasing the system size by dividing the correlation matrix and the input neuron state vector with time division techniques, frequency modulation or phase modulation techniques. Positive and negative valves can also be provided with similar techniques.

摘要： An intelligence information processing system is composed of an associative memory and a serial processing-type computer. Input pattern information is associated with the associative memory, and pattern recognition based on the computer evaluates an associative output. In accordance with this evaluation, an associative and restrictive condition is repeatedly added to the energy function of a neural network constituting the associative memory, thereby converging the associative output on a stable state of the energy. The converged associative output is verified with intelligence information stored in a computer memory. The associative and restrictive condition is again repeatedly added to the energy function in accordance with the verification so as to produce an output from the system.

摘要： Predetermined multiple points of the front passenger seat and its periphery are irradiated with spot beams, caught with a camera, and distances are measured based on the irradiation position of the spot beams. Conversely, the characteristics for each status of use of the seat such as the shapes of the contour of the seat or the contour of a child seat are detected from the picture information caught with the camera. The status of use of the seat is decided based the characteristics for each status of use and the distance information that was previously measured. Based on this decision, the operation of a passive safety device such as an air bag device is controlled.

摘要： After resetting the potential VPD of the photodiode (11) to the predetermined potential VRST, light is incident onto the photodiode (11) for a predetermined period to decrease the VPD corresponding to the amount of the incident light. After that, a declivous ramp voltage VRAMP is applied to the source terminal of the first MOS transistor (12) which is a common-source amplifier for reading out the VPD. When the voltage difference between the gate and source of the MOS transistor (12) exceeds a threshold voltage, the MOS transistor is turned on and the output suddenly decreases. If a signal having a pulse width from the starting point of the sweep of the ramp voltage to the sudden lowering point of the output is generated, the pulse width depends on the amount of the incident light. With the signal readout of this PWM method, it is possible to lower the power consumption while a wide dynamic range is maintained, and to downsize the picture cells to achieve a higher number of picture cells.

摘要翻译： 在将光电二极管（11）的潜在VPD复位到预定电位VRST之后，光入射到光电二极管（11）上一段预定的时间以减小对应于入射光量的VPD。 之后，向作为用于读出VPD的公共源放大器的第一MOS晶体管（12）的源极端子施加斜率斜坡电压VRAMP。 当MOS晶体管（12）的栅极和源极之间的电压差超过阈值电压时，MOS晶体管导通，输出突然降低。 如果产生具有从斜坡电压的扫描的起始点到输出的突然降低点的脉冲宽度的信号，则脉冲宽度取决于入射光的量。 利用该PWM方法的信号读出，可以在维持宽的动态范围的同时降低功耗，并且可以减小图像单元以实现更高数量的图像单元。
