Title: Simulator television system
IPC: H04N5/275
Filed: 1979-05-19
Abstract: In a television system suitable for a computer controlled training simulator in which a model 15 viewed by a television camera 18 is displayed with an electrically generated background, fine detail features of the model are displayed on a high resolution CRT 30 without the expense of a high resolution camera by storing the outline shapes of the details in a memory 40. The overall sizes and positions of the details in any television field are determined by a computer 17 which positions the image of the model. In response to such computer control and for each line of the television field a processor 41 determines the dimensions and positions of the details in the image and causes detail generating means 46 to produce for each line blanking pulses at line positions and for durations corresponding to the portions of the details to be displayed on that line. The generated blanking pulses of the details are combined with camera blanking pulses of the model at 59 and by means of a video gate 29 blank the output of background generator 25. Thus, details too fine for the resolution of the camera are seen as silhouettes. <IMAGE>

Title: Multifrequency Signal Receiver
IPC: H04Q1/453
Filed: 1981-05-28
Abstract: A multifrequency signal receiver (e.g. in a telephone switching system) uses a circuit including two branches each including an analog switch (AM1, AM2), which switches are controlled by a signal (shg) which is a function of a frequency to be detected. Each such switch has its outlet connected to an inlet of a differential amplifier (AO3, AO4). The inlets of each of these switches (AM1, AM2) are fed with a composite input signal (EA) or its inverse (EA) via a resistor network (R5-R8) which controls the gain of the amplifier (AO3 or AO4), the output from which thus represents the product of the composite input signal and the nominal frequency signal. <IMAGE>

Title: Beer dispensing apparatus
Inventor: NORTHEDGE RONALD
IPC: B67D1/12
Filed: 1981-07-01
Abstract: A beer dispensing apparatus has a beer source 30 under pressure, a flowmeter 34 producing digital flow-dependent signals on a line 42, through an ON-OFF valve 36, and a dispensing point 38 with means 46, 48 for detecting whether the beer glass 41 is half pint or one pint size and producing corresponding electrical signals on lines 54 and 55. The latter signals cause valve 36 to be opened and a counter 44 counts the resultant digital flow-dependent signals from the flowmeter 34. When the count reaches a value corresponding to the flow of half a pint or one pint of beer, as indicated by the signals on lines 54 and/or 55, the control system switches valve 36 OFF so as to terminate the beer flow. The flowmeter 34 may comprise a plastics externally finned rotatable element whose rotation is sensed externally of the tube 32 by means which direct focussed infra-red radiation onto the tip edges of the fins which reflect the radiation to a transducer producing an electrical output. <IMAGE>

Title: Optical microswitch system
Inventor: DALGOUTTE DAVID GEORGE
IPC: G08C23/06
Filed: 1982-04-01
Abstract: An optical microswitch system has a source 1 and photodetectors 6, 7 linked with a shutter 5 by means of a single optical fibre 3. The photodetectors detect light of different wavelengths, and the switch shutter 5 obstructs the reflection of one of these, the other being either always reflected or never reflected. The two photodetector outputs are compared in a differential amplifier 12 which operates to cancel out the effect of spurious reflections which are otherwise liable to mask the reflection signal provided by the microswitch. Variable gain amplifier 11 is used to zero the differential amplifier when the first one of the wavelengths is not reflected, and the output of the differential amplifier is divided by the signal for the unaffected wavelength at 13 to compensate for drift of the source 1. <IMAGE>
