Patent GB-2211371-A (GB)
Title: Position warning system
Inventor: MORGAN BRYAN
IPC: F41G7/30
Filed: 1987-10-17
Abstract: In a warning system for a travelling body 63 carrying a receiver RX and crossing one or more boundaries B1 defined between a transmitter TX and transponders TP1, transmitter TX repetitively emits pairs of signals separated by a predetermined interval and each transponder TP1 responds to the first by emitting a signal after a delay. The locus of points at which the transponder signal and second transmitter signals arrive simultaneously forms a boundary B1 which, by choice of transmitter signal interval and transponder delay, can be located mid-way between them and extends orthogonally to a line joining them. A safety region around and above a firing range 60 is formed by boundaries B1 etc. and a missile forms the travelling body 63; if the missile strays to the wrong side of any boundary it self destructs. <IMAGE>

Title: Current sensing circuit
Inventor: HUGHES JOHN BARRY
IPC: G01R19/15
Filed: 1988-04-29
Abstract: A current-sensing circuit senses an output current (IA) of a power semiconductor device (10) which device has a major electrode (14) for carrying the output current (IA) and a minor electrode (16) for carrying a sensing current (IB). The circuit comprises means for impressing on the minor electrode (16) a voltage equal to that on the major electrode (14) and means for monitoring the total current (IB) flowing through the minor electrode. The voltage impressing means has a first input (26) coupled via a first impedance (Z1) to the major electrode (14) and a second input (34) coupled via a second impedance (Z2) to the minor electrode (16), the first and second impedances being matched. The circuit comprises means (N3, N4) for maintaining equal currents (I1, I2) in the first and second impedances so that the differences between the voltages at the first and second imputs (26, 34) is substantially equal to the difference between the voltages (VA, VB) at the major and minor electrodes, while the absolute values of those voltages are translated to levels suitable for the first and second inputs of the voltage impressing means. The circuit is suitable for inclusion in an intelligent power switch integrated circuit. Output HC could be used to actuate an automatic shut down or external warning. Output LC could be used for detecting filament breakage in a loop load 6. <IMAGE>
