Title: In-line proximity switch
Inventor: RITCHIE GORDON STUKELEY
IPC: H05B37/02
Filed: 1987-08-21
Abstract: A proximity switch e.g. for a domestic a.c. supply is connected in-line e.g. in the live line of the supply between live and switch live terminals. No direct connection is made to the neutral line. Switching is performed by a triac which receives a gate input from a control circuit K that includes an optical proximity switch. The control circuit K has a power supply comprising a charge storage capacitor C1 that is charged from the live terminal through a first impedance I1 and a unidirectional first path through diode D1 when the triac is conductive. When the triac is switched to a non-conductive state, the capacitor C1 is charged from the switch live terminal through a second unidirectional path including diode D2 and a second impedance I2. The proximity switch may be replaced by a touch switch or a dimmer switch. <IMAGE>

Title: Performing raster operations on patch formatted pivel data
Inventor: TREVETT NEIL FRANCIS
IPC: G06T1/20
Filed: 1988-03-23
Abstract: A system and method for performing raster operations in a patch access environment utilizes two or more source patches to produce an XY shifted destination patch. Even though the present invention operates in a patch access environment, it can form a destination patch by merging groups of pixels not residing within the same patch boundaries. The shifting and merging used to form the XY shifted destination patch can be done on a patch plane basis or on a patch basis. The X shifting and merging effectively combines preselected contiguous columns of contigous patches. The X shifted patches are then shifted in the Y direction to produce XY shifted patches. A line of the XY shifted patches is stored in a memory. A second, contiguous line of XY shifted patches is also stored in the memory. The stored lines of XY shifted patches are merged and merged XY shifted patches can be read out of the memory in a page mode fashion. Boolean or arithmetic operations can be performed between the merged XY shifted patch and pre-existing data within a destination patch area so as to produce the XY shifted destination patch. <IMAGE>

Title: Electronic distance measuring calculator
Inventor: PHILPOTT ALAN STEWART
IPC: G01B3/12
Filed: 1989-01-31
Abstract: The electronic measuring calculator is an instrument similar to a conventional pocket calculator but which has an interfaced wheel driven pulse generating sensor unit which can be moved over a surface such as a map or plan to give a distance readout directly on a digital display or to a printer. The sensor unit can be built into the instrument or it may be demountable for ease of use, whilst still connected to and interfaced with the measuring calculator circuit. It may include an optical shutter or reflector or have a series of pulses recorded in a magnetic coating and sensed by a record/replay head. The number of pulses from the sensor unit are directly related to the distance covered by the external wheel. After a sample run over the scale of a map or plan the instrument is programmed to display any further movement of the sensor as the actual distance it represents.
