Title: Control of a motor vehicle friction clutch
Inventor: NAGLER FRANZ
IPC: B60W30/18
Filed: 1990-05-16
Abstract: In the automatic control of a motor vehicle friction clutch (1), the clutch is disengaged when the vehicle is stationary and thus, despite the fact that the engine (3) is running and the gear is engaged, the driver can leave the vehicle. In the case of a fault of the clutch system causing engagement of the clutch, the vehicle may set itself in motion. This is prevented by an arrangement in which, when the clutch (1) is engaged with the vehicle stationary, with the engine (3) running and the gear engaged, the brake pedal (21) must be actuated substantially continuously. If during a predetermined time period of for example two seconds at maximum the brake pedal (21) is not actuated, then the engine (3) is shut off or the change- speed gear (5) is set into its neutral position. <IMAGE>

Title: Amplitude digitiser and a direction-finding system
Inventor: KEEPING MICHAEL WILLIAM
IPC: H03M1/16
Filed: 1990-07-20
Abstract: An amplitude digitiser comprises N monolithic broadband microwave nf amplifiers (18A, 18B) in series with an input line (10), and (N+1) video drift detectors (22A, 22B, 22C) coupled (14A, 14B, 14C) to the input line and outputs of the rf amplifiers (18A, 18B). Each video detector is connected to a linear flash analogue to digital converter (24A, 24B, 24C), the outputs of which are connected to a look-up table (26) which supplies a digitised version of the input signal to a processor (28), e.g. to calculate a bearing. To stabilise the gain of the monolithic rf amplifiers (18A, 18B) against temperature shifts and component aging, a noise signal is derived from the output of the (N+1)th video detector (22C), integrated over a long time period, compared (34) with a reference and the output is used (20A, 20B) as a bias correction voltage to control the gain of the amplifiers. A direction-finding system (Fig 2 not shown) uses a plurality of such amplitude digitisers, each coupled to a respective antenna. <IMAGE>
