IPC: H04R1/28
Filed: 1993-06-08
Abstract: A loudspeaker is provided with weights either on top of the loudspeaker or below the loudspeaker or both so that undesirable vibrations generated by a loudspeaker assembly are reduced by the inertia of the weights.

Patent GB-2271659-A (GB)
Title: Coin Validator
Inventor: CHURCHMAN JAMES
IPC: G07D5/08
Filed: 1993-10-14
Abstract: In a coin validator and sorter a coin 1 passes between conductive plates 7, 9 which form a capacitor, which provides part of the frequency controlling capacitance of an LC tuned oscillator circuit 23. The presence of a coin 1 between the conductive plates 7, 9 alters the capacitance, and hence the output frequency of the circuit 23. The oscillator output is supplied to the clock of a counter 31, optionally following frequency division in a frequency divider 27. The counter 31 counts the number of clock pulses received in a 10ms period, and the count value is provided to a microprocessor 75 via a shift register 33. The count value will be a measure of the frequency of the output of the oscillator 23. Microprocessor 35 substracts the count value from a pre-stored reference value, and supplies the difference to a look-up table 47 stored in a memory 37. The microprocessor 35 uses the output of the look-up table 47 to determine whether a valid coin has been received, and if so, its denomination. The pre-stored reference value represents the frequency of the output of the oscillator 23 when no coin is present. Preferably, while no coin is present the microprocessor 39 monitors the count values obtained from the counter 31, and updates the stored reference value so that it tracks drift in the frequency of the oscillator 23. <IMAGE>

Patent GB-2302146-A (GB)
Title: Device and process for actuating a torque transmission device operating between a drive unit and a gearbox
Inventor: SALECKER MICHAEL
IPC: B60W50/02
Filed: 1995-12-22
Abstract: The invention pertains to a device and process for actuating a torque transmission system, such as a clutch with a gearbox that has a control member for shifting the gears, e.g. a gearshift lever (811), and an actuator (804) connected to the control member on the gearbox side, on a central control unit. The inventive concept provides that the at least one actuator sensor (800) or two actuator sensors (800, 801) are coupled in such a way that the travel along the two relevant coordinate directions (translational axis and rotational axis (805)) is detected by means of a one-dimensional sensor (800, 801). Further, the control member sensor (809) detects essentially the shifting travel. The gross information from the sensors allows the signals to be separated according to the coordinate directions of selector travel and shifting travel. When two sensors as per the above process are coupled "diagonally" to the actuator, that is, each one-dimensional sensor senses motion along a projection of a two-dimensional travel, then one sensor can guarantee emergency operation if the second sensor fails, because essentially all essential information is present.

Title: Communication apparatus with directional antenna system
Inventor: KANAI TOSHIHITO
IPC: H04B7/26
Filed: 1996-11-13
Abstract: A gain control circuit 20 calculates the propagation loss between a station 1 and mobile unit 40 using the reception/transmission power and antennae gains of the station and mobile unit respectively. On the basis of the propagation loss, a minimum antenna gain required for communication is obtained and the antenna gain of the station is set to be at least this minimum value. A weight control circuit 14 outputs optimal weighting coefficients to a weighting circuit 11 which weights antenna elements 10a accordingly, thereby electrically setting the directivity pattern of the antenna 10 to ensure efficient communication between the mobile unit and base station. Transmission/reception units 12, 13 measure the reception power and antenna gain of the station in communication and control (non-communication) radio channels respectively.

Patent GB-2320401-A (GB)
Title: Improved multicarrier transmission system
Inventor: TZANNES MICHAEL ANDREW
IPC: H04L25/03
Filed: 1995-11-17
Abstract: The transmitter (100) receives a sequence of symbols and groups the symbols into a block of symbols for which transmission is to be initiated in a following frame. At the receiver (150), the signal from the communication link (113) is decoded by a plurality of finite impulse response (FIR) filters that are matched to the waveforms modulated by the symbols in the transmitter (101). Errors arising from synchronization errors between the transmitter (101) and receiver (150) are corrected by forming weighted sums of the symbols decoded by the FIR filters for the current frame and frames received prior to and/or after the current frame. The weights are determined by training samples sent on the communication link (113) prior to actual transmissions.

Title: Storage electrode formation
Inventor: HIROTA TOSHIYUKI
IPC: H01L21/8242
Filed: 1997-05-30
Abstract: The formation of a localised current path along the interface between the storage electrode layer 231 and the interlayer insulator 209 during storage electrode formation by dry etching is circumvented by bypassing the current through a titanium nitride layer 221, thereby preventing undercutting of the storage electrode. After patterning the storage electrode layer the exposed titanium nitride layer is converted into titanium oxide. In alternative embodiments, the localised current path can be removed altogether by using an undoped silicon layer to form the storage electrode layer or impeded by using a high resistance silicon layer to form the storage electrode. Such silicon layers are ion implanted and/or annealed to form a conductive storage electrode after patterning by dry etching.
