Patent GB-2254146-A (GB)
Title: Determining residual static shift in seismic data
Inventor: HALE RICHARD
IPC: G01V1/36
Filed: 1991-03-08
Abstract: In order to determine residual static shift in common midpoint gather seismic data with reduced likelihood of cycle skips, a pilot stacked trace is formed by stacking the individual common midpoint traces after NMO and possibly DMO. Each of the traces is cross-correlated with the pilot stacked trace and the correlation function is modified by being progressively decreased on either side of a time value which is equal to the weighted sum of static shifts for geographically adjacent traces. These steps may be repeated. The static shift is determined as the time shift of the maximum of the modified correlation function. <IMAGE>

Title: Extended range cordless telephone system
Inventor: EVANS JAMES G
IPC: H04W84/16
Filed: 1991-07-25
Abstract: The system employs multiple base units 12 to 17 and multiple handset units 18, 19 with only one of the multiple base units being activated at a time for communicating with a given handset unit. Each of the multiple handset units 18, 19 has an assigned or dedicated base unit 12, 15 with which only it may communicate. Other shared base units 13, 14, 16, 17 with which all the multiple handset units may communicate are also located in the system which supports multiple simultaneous users. An associated radio link control unit 111 controls the activation and deactivation of the base units which are dispersed through a premises. This control unit also controls the connection of a voice path to the base unit actively communicating with a handset unit. As a user of a handset unit with a call in progress roams around the premises, this base unit monitors the quality of the signal received from the handset unit. If this signal quality deteriorates to below an acceptable level, the base unit notifies the radio link control unit which, in turn, initiates a polling procedure to identify and hand-off the communications to another base unit that is then receiving the signal from the handset unit with an acceptable signal quality. With no calls in progress, both base unit and handset unit transmitters are off thereby avoiding interference to other nearby cordless telephones. All receivers are active, however, in order to respond to incoming calls and service requests. Channel cycling and base unit polling procedures are advantageously employed to insure that incoming or outgoing calls are completed quickly, even though the location of a roaming handset unit may be unknown. <IMAGE>

Title: Gas sensing resistance transducer element
Inventor: MCGEEHIN PETER
IPC: G01N27/12
Filed: 1991-08-05
Abstract: The element comprises a porous SnO2 body containing a fine dispersion of a metal such that the resistance variation response characteristic of the transducer is partially suppressed at gas concentrations up to about 10 ppm, while being substantially unsuppressed at concentrations in the approximate range 10 - 300 ppm. The metal may be Pb, Ir, Au, Rh, Pb, Ni or Bi, traces of alkali or alkaline earth metals or a congener of any of these metals. The transducer may also include Pt, Pd, Ir or Rh, As, Sb, P or ammonium. The dispersion is formed by solution impregnation with a salt, preferably a nitrate, and precipitation of the metal, preferably with subsequent heat treatment to control particle size.

Patent GB-2260242-A (GB)
Title: Mobile radiotelephone system having service request retry controlled by signal strength
Inventor: KALLIN HARALD
IPC: H04W36/16
Filed: 1992-10-02
Abstract: A base station BS11, upon receiving a service request from a mobile station MSN+1, ascertains whether the service request can be accepted according to the availability of voice channels in the base station, and, if the service request cannot be accepted compares a measured signal strength of the service request with at least one threshold value. If the signal strength exceeds the threshold, the mobile station is directed to retry the service request on one or more of a first set of channels assigned to neighboring base stations. otherwise, the mobile station is directed to retry the service request on one or more of at least a second set of channels assigned to neighboring base stations. Accordingly, directed retries nearer the interior of a cell may be restricted or eliminated, whereas directed retries toward the periphery of the cell may be freely allowed or less severely restricted. Since interference is greater from mobile stations transmitting nearer the interior of a cell on the frequency of an adjacent cell than from such mobile stations transmitting from the periphery of the cell, interference is therefore reduced. <IMAGE>

Title: Abnormal current cutoff circuit.
Inventor: SUGINO KOICHI
IPC: H02H3/08
Filed: 1993-07-29
Abstract: In a print head drive arrangement, when a driver section 3 is being driven by a power supply circuit 1, power is provided to a driver circuit 2, which drives the section 3, via a transistor 5 which is connected in the power supply line and which is turned on by a transistor 7. When the arrangement goes into a standby state, transistor 5 is turned off, so that current is supplied to driver section 3 via a fuse 4 and diode 6 connected in parallel with transistor 5. If an abnormal current then flows during the standby state, fuse 4 will be broken, and transistor 7 will therefore be turned off so that transistor 5 will also be held off, which ensures that the power supply line is cut completely. The fuse 4 may be replaced by a circuit breaker, and a watchdog timer may be included. <IMAGE>

Title: Loudspeaker
Inventor: WATKINSON JOHN RONALD
IPC: H04R1/28
Filed: 1995-01-26
Abstract: An additional transducer 3 is mounted behind a conventional diaphragm type transducer 1 and actively driven in such a way that the acoustic conditions on the rear of the conventional transducer diaphragm are substantially as if it were in an enclosure of infinite volume, e.g. the pressure in the front portion of the enclosure 2 remains substantially constant. The differing acoustic conditions experienced by the two transducers require that their respective drive signals will be substantially different. The driving signal for the rear transducer may be formed by feedforward processing of the signal driving the front transducer and/or feedback processing of a pressure signal. The rear transducer may be replaced by several transducers (figs 2A, 2B). Electrostatic or piezolectric transducers may be used in either front or rear position (figs 3,4), or a hydraulic ram may be used in the rear position (fig 5). A drive unit having dual independently driven diaphragms that is suitable for this application is disclosed (fig 6).

Title: Security device
Inventor: MCCARTHY SHAUN
IPC: G06F21/88
Filed: 1995-02-25
Abstract: To inhibit the theft of an electronic device comprising a processor unit controlling a display, the electronic device includes a receiver unit to receive remotely transmitted signals to cause the processor unit to at least partially obscure or change the output on the display device, e.g. by overprinting a message informing you that the device is stolen with a unique identification code in that message. This enables the authorities to identify the true owner of the article. The receiver unit can be the receiver of a radio pager. Thus, on noticing the theft of the device the owner alerts a service provider who activates the receiver unit.
