摘要： An optical system superposes an optical carrier with modulation and an additional optical carrier. The system is designed in such a way that it supplies the superposed optical signal with modulation at one of its outputs and the superposed optical signal without modulation at an additionnal output. The generator is designed in such a way that it is as insensitive as possible to ambient influences. The optical signal without modulation constitutes the feedback signal for the frequency/phase control of the laser emitter. The optical signal with modulation is available for further processing, for example in a beam shaping network.

摘要： A camera producing colour video outputs may employ an image intensifier 5 and a monochrome CCD sensor 3. The scene is exposed through filters F 3 , F 4 which may each contain stripes of subtractive primary colours alternating with clear regions. The video is decoded using waveforms derived from a memory which records the output of the sensor when imaged on, for example, primary colours such as red and blue, producing trains of pulses which identify the spatial regions of each line corresponding to the spatial areas of the pattem on the sensor produced by the colour filters F 3 , F 4 , in order that actual scenes can be decoded using the stored waveforms, for example using sample and hold devices. A colour interference signal is generated in matrix addition circuitry 10 to produce a luminance signal which has stripe visibility removed from it, permitting high resolution video signals to be obtained.

摘要： A method for making three dimensional objects comprising the following steps. Making a plurality of sheets (42) and then stacking the sheets to form a stack (40) which corresponds in shape to that of the object. The sheets have an intermediate layer supporting a solder layer on each of their sides. The stack is then heated and the sheets are bonded together by diffusion soldering.

摘要： A terrain advisory system for an aircraft (A) comprises a processor (11) which compares terrain information, accessed from a memory means 13 according to data from a navigation means (12), with dynamic flight parameters from a monitor (14) for the aircraft (A). The processor (11) also generates a trajectory signal and a pull-up signal to indicate, on a display means (15), the current aircraft trajectory relative to a line constructed from notional pull up trajectories for the aircraft (A) which avoid a predetermined clearance height without exceeding a predetermined acceleration acting on the aircraft during a pull up manoeuvre.

摘要： An acoustic sensor for use as part of a drill string (1) in a borehole (2) has an acoustic transducer (4) which vibrates the drill bit in contact with the rock at the end of the borehole to generate acoustic signals in the rock. These acoustic signals propagate through the rocks ahead of the drill bit and are reflected and scattered to return to an acoustic sensor contained within the drill string.
