Title: Method and apparatus for acoustic signal detection
IPC: G01V1/50
Filed: 1978-09-07
Abstract: The disclosure relates to a method and apparatus for acoustic signal detection, adapted for use in acoustic velocity well logging to measure the difference in transit times of an acoustic signal between a transmitter and two or more receivers. In a preferred embodiment of the present invention two timing measurements of the signal R1s, R2s arriving at each of two receivers (R1, R2 Fig. 1, not shown) may be made by activating zero crossing detectors at the arrival of the first negative and first positive half- cycles at each receiver. A transit time is calculated from the zero crossing times following the first negative half-cycle. This first transit time A'-A may be checked for accuracy by comparing the first transit time with a second transit time B'-B calculated from zero crossing times following the first positive half-cycles, by comparing the first transit time to a previously measured transit time and/or by detecting the order of arrival of the negative and positive half-cycles to determine whether the half-cycles have been detected out of sequence at either receiver. Should the first transit time be determined to be inaccurate, the previously measured transit time or the second transit time may be substituted therefor. <IMAGE>

Patent GB-2051440-A (GB)
Title: Remote light switch
IPC: H05B37/02
Filed: 1979-06-14
Abstract: This is a simple device to ease the wiring of electric light circuits by obviating the need to run wires from each light to a wall mounted switch. This is achieved by replacing the wall mounted switch by a battery operated signal sender which sends a signal to a signal receiver mounted on the electric light cable and so operates the switch - the signal receiver and the switch being positioned close to the light (possibly in the ceiling rose). The signal receiver should include a battery sense and when the battery is low send a signal (when operated) which will cause the light to switch on/off/on (or the reverse) to indicate the need to change the battery. The signal receiver and sender should be of adjustable "frequency" and set to match each other on installation. The signal will probably be infrared light. The application has considerable safety benefits as well as being labour (and cost) saving.
