Patent GB-2290840-A (GB)
Title: Fail-safe brake actuation system
Inventor: RICHARD ARTHUR
IPC: B60T13/74
Filed: 1994-06-01
Abstract: A brake actuator uses an electric motor to drive a ball screw to compress a brake-actuation spring to release the brake. After the spring has been compressed to release the brake, the electric motor is de-energized, and the spring is prevented from re-engaging the brake by virtue of the fact that the electric motor is connected to the screw via a high ratio gear reducer, which will not reverse-drive. An electric clutch is included between the ball screw and the gear reducer, the clutch being held, electrically, in the locked or drive condition while the brake is required to be held off. The brake is re-applied by releasing or de-energizing the clutch to the non-drive or free condition. <IMAGE>

Title: Capacitive position transducer with feedback
Inventor: DOWD ROGER D
IPC: G01D5/241
Filed: 1994-05-27
Abstract: A variable capacitance high precision, stable transducer for detecting position of a moving member has a first stationary conducting surface 12 connected to an oscillatory electric source, a second surface 14 with at least two conducting, sensing regions, and a third movable conductive surface 15 located between the first surface and the second surface and connected to the moving member e.g. via shaft 18. The third surface 15 has lobes 16, 17 adapted to modulate charge transfered from the source surface before reaching the sensing regions 14a - c. The difference of signals detected at the individual sensing regions is utilized to determine the position of the moving member, and the sum of the signals is utilized to achieve appropriate correction in a feedback loop connected to the source e.g. to keep the total capacitive current constant. The sensing surface 14 and movable screen 15 are held at approximately the same potential by diodes. <IMAGE>

Patent GB-2288807-A (GB)
Title: Delta-latroinsectotoxin
Inventor: BELL DAVID ROBERT
IPC: A01N63/50
Filed: 1995-04-24
Abstract: The isolation of a protein and the cloning and expression of the corresponding gene which encodes the neurotoxin delta-latroinsectotoxin (delta-LIT) is disclosed. The protein is isolated from the venom of the Black Widow Spider, Latrodectus mactans Tredecimguttatus. The native gene encodes a precursor protein which is non-toxic. Truncation of the gene at both the N-terminus and C-terminus yields a toxic protein which can be expressed in bacterial cells. It is postulated that delta-LIT may be used as an insecticide. In addition, the gene may be introduced and expressed in both plants and non-human animals.

Patent GB-2298994-A (GB)
Title: Remote activity logging
Inventor: DODD CHRISTOPHER JOHN
IPC: H04M9/00
Filed: 1996-04-25
Abstract: Message reception apparatus 6 has a plurality of telephone lines from a PSTN 4, each line corresponding to a service provider, eg a nurse, warden etc, who may be attending an elderly person in a residential home. The provider uses a normal telephone 2 of the person who is being provided with services to inform the reception apparatus 6 and a computer 8 of the provider's presence. The reception apparatus 6 detects which line the call is placed on and the calling line identity (CLI) on that line. From this information the reception apparatus can derive which service is being provided to whom. A computer 8 will log this information and the time that the call was made, storing this data in a client database in the computer 8. By the service provider calling at the start and end of a job, the computer 8 can log the total time spent by the service provider and invoice appropriately. The reception apparatus 6 does not need to answer the calls to log the actions of service providers, thereby reducing costs.
Patent GB-2301731-A (GB)
Title: Speakerphone
Inventor: KARNOWSKI MARK J
IPC: H04M9/08
Filed: 1996-05-30
Abstract: In a speakerphone, which operates under software control, transmit and receive signal levels are sampled and compared against one another, with hysteresis, to enable one of two speakerphone modes of operation - either a transmit mode or a receive mode. A single peak detector 146 is multiplexed to sense the transmit and receive signal levels. Fixed attenuators 134, 138 are switched into either the receive signal path or into the transmit signal path, depending upon the current speakerphone operation mode. Signal compression is used to provide for improved mode determination over a wide dynamic range. The level detection and/or attenuation may be performed in software. The speakerphone functions are readily implemented using standard line interfaces and control circuitry. Automatic gain control in the receive mode ensures a constant level of signals at the speakerphone loudspeaker 152, regardless of telephone line conditions.

An actuator 84 cooperates between the frame 12 and the outer ring 56 to selectively prevent rotation of the outer ring 56.
Patent GB-2318228-A (GB)
Title: Trimming circuit including an antifuse
Inventor: GOLDMAN RICHARD
IPC: G11C29/02
Filed: 1996-10-09
Abstract: To monitor the state of an antifuse capacitor C, a transistor T5 is connected to the capacitor such that it saturates only when the capacitor is not blown. Monitoring the base current of the transistor allows the state of the capacitor to be monitored without needing to use a conventional high-voltage comparator. As shown the transistor T5 draws a relatively small base current when the capacitor C is blown, node I1 then being at ground potential, and transistor T12 is off so that output terminal I3 is pulled toward the supply voltage V1. When the antifuse capacitor is not blown it is charged via transistor T5, which is then saturated and its excess base current causes transistor T12 to be turned on, pulling the potential of output terminal I3 toward that of the ground rail. To blow the antifuse capacitor, node I2 is temporarily grounded so that current flows through transistor T2 and correspondingly through transistor T4 in a current mirror circuit, pulling the potential of node I1 toward negative supply voltage -V2.

Title: Control of engine starting in a motor vehicle with an automatically-controlled clutch
Inventor: SALECKER MICHAEL
IPC: B60W30/18
Filed: 1997-08-01
Abstract: A motor vehicle 1 with an engine 2, an automatic clutch 3 and a gearbox 4 has a control unit 15a and an actuator 15 controllable by the control unit for operating the clutch. Upon attempted starting of the engine, the control unit 15a receives and processes a sensor signal from a sensor which detects a neutral position engaged in the gearbox. The control unit, when it detects that neutral position is engaged in the gearbox, disengages the clutch and sends a starter release signal to allow starting of the engine. When neutral position is not engaged, the control unit either does not allow starting of the engine or disengages the clutch and checks that brakes are applied before the engine is started. The engine may be started automatically if starting is attempted with neutral not engaged and neutral is subsequently selected within a predetermined time.
Patent GB-2328092-A (GB)
Title: Vehicle braking intensity indicator
Inventor: HALL CHRISTOPHER PETER
IPC: B60Q1/44
Filed: 1997-08-02
Abstract: A pressure sensing device 47 is linked to a motor vehicle's braking system and causes a rearwardly directed visual display unit 1a, 1b to indicate the intensity of braking. A plunger 16 coupled to the brake pedal 12, or another part of the brake operating linkage, moves a contact 15 into engagement with different ones of fixed contacts 14 as braking pressure increases. The contacts 14 are connected to a control unit 10 comprising diodes 9 which cause increasing numbers of lamps 7 to be energised as braking intensity increases. A different form of pressure sensor has an elongate movable contact (21, Fig.8) which contacts increasing numbers of the fixed contacts 14 with increasing brake pressure, so that the diode array 9 is not then required. Braking intensity may alternatively be indicated by varying the intensity of brake lights 7 by means of a variable resistor (25, Figs.12-14) linked to the brake pedal. A further form of sensor may be a brake fluid pressure sensor (33, Fig.18,19). A sensor of the variable resistor or fluid pressure sensing type may be connected to a bargraph driver IC (39, Fig.19) to cause increasing numbers of brake lamps to be energised with increasing braking intensity. The driver IC may also operate an LED display unit (41) mounted on the dashboard.
