摘要： By placing a mirror in the field of view of an infrared imager it is caused to produce an image of its own detector assembly which is correctly focussed when the lens system is focussed at infinity. This phenomenon is used either manually or automatically to focus the system.
摘要翻译：通过在红外成像仪的视野中放置反射镜，产生其自身的检测器组件的图像，当镜头系统聚焦在无限远时，该检测器组件被正确聚焦。手动或自动使用此现象来对系统进行对焦。

摘要： In a radar receiver signals at IF are converted to digital form at 22 and the real and imaginary components are separated at 24 and 25 before passing to respective digital low-pass filters 28 and 29. These filters operate by adding samples within blocks of a given number of samples. In order to reduce the response of these filters at the sum frequency the first and last member of each blocks of samples taken by the filter is weighted so as to reduce its value relative to the center values of the batch which are left unchanged relative to each other.

摘要： A thermal imaging device uses a compensated cholesteric liquid crystal mixture as its thermo-optic conversion element. The mixture is obtained by mixing two cholesteric liquid crystals, one with a left-handed twist and the other with a right-handed twist. The twists cancel at a compensation temperature, the mixture thus having infinite twist at this temperature. The device is designed to operate with the mixture held in the region of the compensation temperature.

摘要： The present invention enables compression of digitized pictorial data to be achieved by comparing a data block of a predetermined size with a group of patterns relevant to that size held in a library. If a match is found the data block is represented by a code identifying the pattern on an output signal by a code identifying the pattern. If no match is found, the data block is sub-divided into smaller blocks which are compared with another group of patterns relating to the smaller block size. This sub-division process continues until the data is matched or a predetermined minimum size of data block is reached, in which case the data itself is applied to the output signal. The compressed data may be reconstituted and displayed or used to monitor the progress of a vehicle, for example.
摘要翻译：本发明能够通过将预定大小的数据块与保存在库中的与该大小有关的一组模式进行比较来实现数字化图形数据的压缩。如果发现匹配，则通过识别图案的代码，通过识别输出信号上的图案的代码来表示数据块。如果没有找到匹配，则将该数据块细分为与与较小块大小相关的另一组模式进行比较的较小块。该分割处理继续直到数据匹配或达到数据块的预定最小大小，在这种情况下，数据本身被应用于输出信号。例如，压缩数据可以被重构并显示或用于监视车辆的进度。

摘要： A differential relay includes two apparatus each associated with a different monitoring point on the line being protected by the relay. Each apparatus includes means for deriving digital data representative of the current monitored at the respective point, at time intervals defined by a clock within the apparatus. The two points are linked by a digital data communication channel, and information transmitted between the two points is used to compute digital data for the two points at substantially the same time, from digital data derived at different instants at the two points.

摘要： A frame transfer buried channel CCD image sensor incorporating an anti-blooming drain structure (25, 27) wherein accumulation of charge of opposite polarity to that drained by the anti-blooming drain structure is prevented. This can conveniently be achieved by arranging for the buried channel diffusion (19) in each channel to stop short of the anti-blooming drain diffusion (25) on one side of each channel. As a result of the prevention of charge accumulation the anti-blooming drain structure remains effective with optical overloads much greater than the optical overload at which anti-blooming performance begins to deteriorate in conventional buried channel CCD image sensors.

摘要： The invention concerns an electronic ringing circuit for telephone systems. A capacitor is connected to the center tapping of a first coil inductively coupled to a transistor-controlled supply line. The other side of the capacitor is connected to the junction between two switches each switch being connected via an induction coil to one end of the first coil so that when the switches are switched in opposite senses load current is drawn in alternate directions from the capacitor.
