Title: Variable colour spotlight
Inventor: PIERCE-HARVEY PETER ROGER
IPC: F21S8/00
Filed: 1990-01-15
Abstract: The spotlight includes two discs 15, 17 around the periphery of which are arranged a plurality of different coloured filters which may be selectively interposed into the beam at an antifocus, preferably close to the light source 1. Which and how many filters are interposed and what portion of the beam they intercept determines the hue and saturation of the output beam. Because the filters are at an antifocus of the system the projected spot will be uniformly coloured but will have an admixture of white light dependent on the amount of the beam not intercepted by the filter. As an alternative the apparatus may project an image of the filter plane so that a spot divided into coloured and non-coloured regions can be produced using a filter partly intercepting the beam. The filters used are preferably dichroic and reflect that portion of the light incident on them that they do not transmit. <IMAGE>

Title: A system for creating the effect of a stationary or moving image
Inventor: WALSH PAUL WARREN
IPC: G09F19/22
Filed: 1990-03-28
Abstract: A system for creating the effect of stationary or moving images, in the eye of a moving observer, has a series of stationary displays (A,B,C) mounted on a tunnel wall for viewing in sequence by the observer in a train moving in direction M. An isolator in the form of slits in a screen enables each display to be viewed separately from the other displays in the sequence and the separate images of each display formed in the eye of an observer are superimposed to form the stationary or moving image. If each display is identical then a stationary image is formed, alternatively if each display is arranged to represent sequential movement, then a moving image is formed. Alternatively, the displays may be mounted on the back of the screen and a mirror mounted on the tunnel wall (Fig 2). Instead of using slits, a series of flashes triggered by the moving train light the displays sequentially (Fig 3). <IMAGE>

Filed: 1990-04-12
Abstract: Power to a load, such as an incandescent or discharge lamp or a motor is controlled by a touch-operated device 11, 13 mounted behind a flexible area 23 of a cover plate 21. The device may be a capacitive touch plate, load cell, pressure sensor, membrane switch or particularly a membrane voltage divider whereby momentary pressure on area 23 flexes a conductor 11 into contact with a resistive track 13 to provide a momentary output signal at a voltage dependent on the position of the operator's finger along area 23. A comparator (50), (Fig 5), causes an electronically adjustable voltage divider (47) to produce a corresponding continuous voltage which is applied to a dimming circuit (51). A RAM with backup battery, or a non-volatile memory may store the setting of divider (47) so that load power may be restored to the level set prior to a power source interruption. An LED array (39), (Figure 4), may indicate power level. A plurality of the devices 11, 13, 21 may be provided for multi-location control (Fig 7), and one or more devices may be incorporated into a hand-held wireless remote control, e.g. having an infra red link. <IMAGE>

Title: Tracking using neural networks
Inventor: MCLOUGHLIN NIALL PETER
IPC: H04N7/18
Filed: 1991-11-28
Abstract: To track one or more moving objects within a field of view, successive frames of the image of the field of view are processed 104 to obtain optical flow data comprising, for each pixel of the image and for each direction of orientation, a measure of the component change of image intensity at that pixel. The optical flow data components are then applied to three-layer neural networks 107 each arranged to output one of the components of the position of a centroid of one moving boundary defined by the optical flow data, the learning rules of each network including a decay constant so that the network functions as a short-term memory and continues to output the approximate centroid component values in the absence of an input, for instance due to occultation. The centroids and image of the field of view are applied to a further neural network which is trained to recognise object shape, so that the object may be tracked through collisions and partial occultations. The output signals drive a camera to track the object. <IMAGE>
