Title: Machine vision stereo matching
Inventor: TOH PENG SENG
IPC: H04N13/239
Filed: 1990-12-28
Abstract: Corresponding points 11(U1, V1) and (U2, V2) 15 in at least two different images of a scene are matched by the use of epipolar lines. A point 11 is selected in one image and the position of the resulting epipolar line 16 is calculated using matrices defining parameters associated with the capturing of the image. The epipolar line 16 is used to identify in the other image points as potential matches to the selected point in the one image. Further constraints are applied to the identified points to find the one point in the other image that most likely matches the selected point. By using three images from different vantage points, intersecting epipolar lines giving a 'fix' can be obtained (Fig 2). <IMAGE>

Title: An automatic gain control circuit for a video camera
Inventor: LEE CHUL-KYOO
IPC: G06F15/78
Filed: 1991-05-30
Abstract: The automatic gain control circuit is arranged to maintain the output video signal level constant even when the gain control circuit is reacting to changes in incident light. In this respect, the lens 1 of the camera focuses the incident light on an image sensor 12 which converts the light into electrical signals, the level of which is controlled by an AGC circuit 4. The gain of the AGC circuit is controlled by an AGC detector 8 responsive to the output of the AGC circuit 4. An iris driver 9 is also responsive to the output level to adjust the iris of the lens 1. Control means 13, 14, 16 are provided to detect the operation of the iris driver 9 and to control or prevent adjustment of the gain of said AGC circuit 4 in dependence upon the operation of said iris driver. The control means comprise an analog switching stage 16 which controls the connection of the AGC detector 8 to the AGC circuit 4. A micom 14 may momentarily supply the appropriate level for the AGC circuit whilst the iris is changing state. <IMAGE>

Title: Pump priming apparatus.
Inventor: WINDSOR RODNEY JAMES
IPC: F04D9/04
Filed: 1991-06-26
Abstract: A motor 3 drives a diaphragm pump 2 to create a vacuum in a tank 1 which is connected via a vacuum line 12 to a pump 4 to be primed. A valve 13 is disposed in line 12. When the pump 2 is activated a vacuum is produced in the tank 1 and then in the pump 4 when valve 13 is opened, thus priming the pump by allowing the fluid to be pumped to enter via inlet 14. Valve 13 is closed to maintain the vacuum in the pump following which the motor 3 is switched off and primed pump 4 operates normally. The pump 4 has a gate valve 16 which is closed during priming. A spring loaded flap 18 in an opening 17 of the tank allows any excess fluid sucked up during priming to be subsequently exhausted. The motor 3 may be powered by hydraulic, pneumatic or electrical means. The apparatus may be attached to a tractor and be powered from the tractor's hydraulic system. 7a <IMAGE>

Patent GB-2251354-A (GB)
Title: Interpolator for use in signal processing
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N7/01
Filed: 1991-11-15
Abstract: A sampled input signal, e.g. a video signal, is processed to provide output signals appropriate for positions between input samples by interpolating between the input samples using an interpolating transversal filter (110) and filtering the interpolated signal with a second filter (150) the gain of which increases with increasing frequency. The coefficients of the interpolating transversal filter are chosen so as simultaneously to compensate the frequency response of the second filter and to provide a desired position offset of the output samples with respect to the input samples. The interpolation and filtering steps may be reversed in order. Surprisingly the interpolation is improved in quality when it incorporates a de-emphasis operation in this way. The sampling may be the sampling achieved by the video signal line structure. A non- linear circuit (140) such as a gamma corrector may be interposed between the interpolator and the equaliser. The system can in particular be used to process the video output of a telecine, or to process digital audio signals. <IMAGE>
Patent GB-2253657-A (GB)
Title: Improvements in or relating to gas turbines
Inventor: TAYLER COLIN ANDREW MILLAR
IPC: F02C7/12
Filed: 1991-12-04
Abstract: A gas turbine has a combined compressor/turbine rotor 14 in which the same rotor blades 16, 17 are used for both compression and expansion depending on which annular segments the blades happen to be passing through. When passing through compressor segments the blading and rotor are subjected to comparatively cold air, whereas when passing through turbine segments they are subjected to the high temperature gases from the combustion chamber. The blading and rotor as a whole are therefore only subjected to a mean temperature somewhere between these high and low temperatures. The entry temperature of hot gases from the combustion chamber can therefore be increased above the levels conventionally employed, with a consequent increase in the thermodynamic efficiency of the turbine, since it is now the lower mean temperature which determines the temperature limit for the materials. The rotor blades may be symmetrical in cross-section (Fig 3b) and gas may pass through a series of flow paths of decreasing cross-sectional area during compression and of increasing cross-sectional area during expansion. The turbine may be used in a power generator (fig. 4) or a propulsion engine (fig. 6). <IMAGE>
