Title: Wind measurement
Inventor: STRACHAN JOHN SCOTT
IPC: G01P5/02
Filed: 1987-02-03
Abstract: A device for measuring wind speed and direction comprises four identical tubes (12a-12d) equispaced about a solid column (10). Each tube (12) is open at the top, and is closed at the bottom by a film (14) of a polymeric piezoelectric material. Wind blowing across the open end induces Helmholz resonance of the air column within the tube (12) and hence movement of film (14) at the bottom. The average voltage output of the four films (14) is a function of wind speed, and the relationship of the output amplitudes from the several films (14) indicates wind direction. <IMAGE>

Title: Inertia sensor
Inventor: JACKMAN PETER RONALD
IPC: H01H35/14
Filed: 1989-01-19
Abstract: An inertia sensor comprises two individual sensors 13 each of which has a poor response to accelerations in a given direction or directions. The sensors 13 are arranged so that a direction of poor sensitivity of one sensor is different from that of the other. When the assembly is subjected to acceleration in a direction to which one sensor has poor sensitivity, the other sensor will respond with greater sensitivity and its output can then be used as an output of the assembly. Each sensor 13 is held in a rest position by a magnet 14 and bridges two contacts 11, 12 when a sufficient acceleration is applied. <IMAGE>

Title: Motion compensation for colour video signals
Inventor: DORRICOTT MARTIN REX
IPC: H04N7/32
Filed: 1992-02-13
Abstract: A motion compensation technique for colour video signals R, G, B involves deriving at least one principal component P1 representing a statistical average colour of the video signal, from the video signals by means of a hotelling (KARHUNENLOEVE) transform circuit 12 and a matrix 10'. Motion compensation is applied to an interpolator 14' (or to a compressor/ decompressor) on the basis of the derived principal component P1. The technique avoids the need to provide three separate compensation circuits for each of the video signals R, G, B while ensuring that optimum use is made of the colour information in the video signals. <IMAGE>
