Title: A video synthesizer for a digital video display system employing a plurality of gray-scale levels
IPC: G09G5/00
Filed: 1978-08-29
Abstract: In a digital video display system wherein characters are displayed in the form of images of the complete character rather than a dot-matrix pattern, a character generator stores signals representing the various characters which are retrieved from storage in response to a character code. The signals specify, in binary-coded form, the gray-scale or luminance values for the various picture elements making up the character image, and are supplied to a video synthesizer that generates the video signal to display the character images which may be displayed in a number of different modes including white-on-black, black-on-white, black- on-gray, and white-on-gray as well as different combinations of such modes to represent a cursor. The video synthesizer converts from binary-coded form to "thermometer" code which is fed to a summing network for D-to-A conversion. The voltage output signals differ from level to level in accordance with the 2.2 root of luminance. <IMAGE>

Title: Improvements in television circuits
IPC: H03L7/16
Filed: 1981-05-08
Abstract: The present invention relates to a television circuit and is particularly concerned with a circuit for deriving from a sub-carrier a signal having half line frequency. In the 625 PAL system used in the United Kingdom and elsewhere the line frequency is 15,625 Hz and the sub-carrier frequency 4,433,618.75 Hz. Therefore to derive a signal of half line frequency it is necessary to divide the sub-carrier frequency by 567,5032. This invention provides a provider comprising controllable divider means (10) having two division ratios and means for selecting one of the division ratios by application of an external signal and means (20) for periodically applying a control signal (18) to the controllable divider means (10) so that for a proportion of cycles an output signal is derived by the first division ratio while during the remaining cycles the input signal (fsc) is divided by the second division ratio whereby the average division ratio averaged over all the divided pulses is not a whole number. An enhanced circuit includes a modifier (32) connected to the control input of the divider means (10) so as to add two control pulses in each field to maintain the divider in the higher division ratio. Conveniently, the output from the divider is fed to a phase comparator (40) of a phase-locked loop the output of which is equal to the average frequency of the pulses of the output of the controllable divider means (10). <IMAGE>

Title: Intruder alarm device
Inventor: WHITE BARRINGTON JOHN LEONARD
IPC: G08B29/18
Filed: 1981-08-17
Abstract: In an intruder alarm device using, the Doppler effect, to reduce the incidence of false alarms, a circuit (16) operates in response to the receipt of an apparent alarm signal by a receiver to stop the wave transmission by a transmitter (10) and to start a timer (20). If the apparent alarm signal terminates when the wave transmission stops, at the end of the timed period a further circuit (22) provides an alarm signal. If the apparent alarm signal continues when the wave transmission stops, indicating a spurious response e.g. due to noise or electrical interference, the timer (20) is reset and the provision of the alarm signal is prevented. <IMAGE>
