Patent GB-2258361-A (GB)
Title: A synthetic aperture radar
Inventor: RICE DAVID EDWARD
IPC: G01S13/90
Filed: 1986-06-18
Abstract: A number of synthetic aperture processing channels 15, 16 are matched to different Doppler frequencies to detect moving targets. These channels operate on relatively long radar pulses and give low radial resolution. Otherwise a moving target would not remain in one resolution cell during the integration time of the processor. Low resolution is also essential to reduce processing requirements. Stationary targets and targets with low radial velocities are detected using a single higher resolution channel 8 matched to stationary targets. The range and velocity ambiguity associated with a single detection for each target is reduced through the introduction of secondary processing 11, 21 in further channels throughout the ambiguous range, using further sets of Doppler frequency S.A.R channels 11A, 21A. An additional low resolution channel 24 is matched to a Doppler frequency appropriate to stationary targets. The output from this is correlated with a digital map 26 to identify the current location of the radar. This information is used to identify the appropriate part of a pre-recorded map and superimpose it on an indication of the identified targets. <IMAGE>

Title: Recognizing batteries connected to a charger
Inventor: MAASLAND HANS-HERMANN
IPC: H04Q9/08
Filed: 1986-10-29
Abstract: In a system for recognizing batteries connected to a charger, the charger transmits a signal band consisting of a periodically varying signal to initiate the generation of a battery-indicating return signal at a battery connected to the charger. The return signal comes from selectively-switched-in resonant circuits 12-19 which respond when the battery 1 is addressed by a frequency-varying signal from a voltage- controlled oscillator 21 driven by a sawtooth generator 20. Operation can be started by the connection of the charging cable 4. <IMAGE>

Title: Clock synchronisation
Inventor: PONSARD BENOIT
IPC: H04L7/033
Filed: 1988-11-11
Abstract: In an arrangement, e.g. a phase lock hoop, for synchronising a local clock with the transmission clock in a received digital signal S, synchronisation problems due to a long initial synchronisation time at high transmission rates and destabilisation of the local clock control loop with temporary absence of transmissions in received signal S are resolved by the inclusion of a pre-processing circuit 5 which selectively supplies a particular one of two versions R1, R3 of signal S differing in phase and derived from a delay circuit 6 to input ST of the synchronisation circuit in dependence upon the phase difference detected at 9 between signal S and an auxiliary clock CKA and supplies the clock CKA itself to input ST in the absence of the signal S. The selected signal R1 or R3 has a smaller phase difference with respect to the local clock to facilitate rapid synchronisation. The local and the auxiliary clocks are arranged to operate in synchronism. …<IMAGE>…

Title: Vehicle four-wheel steering system
Inventor: BAYLE ROBERT
IPC: B62D7/15
Filed: 1989-08-24
Abstract: A front wheel steering unit drives a shaft (6) of a rear wheel steering unit 5. Carried for rotation with the shaft (6) is a gear segment (15) meshing with a further gear segment (18) which is pivotally mounted by a pin (19) on a housing (17) which is also pivotally mounted on the shaft (6). The gear segment (18) provides a lever from which tie-rods (22) extend to the rear wheels. During initial rotation of the shaft (6), the gear segment (15) moves (22) against biasing springs (23) and moves tie-rods (22) in a first direction via the gear segment (18). On continued rotation, segment (15) abuts the housing (17) and rotates in unison therewith so that the gear segment (18) is displaced with the housing (17) to move the tie-rods (22) in the opposite direction, i.e the steering applied to the rear wheels is reversed. Pivotal displacement of the housing (17) with the gear segment (15) is resisted by biasing springs (24) which react between the carrier and arms (25) on afixed frame (13). <IMAGE>
