Title: Phased arrays of ultrasonic emitters used with a mobile receiver
Inventor: OWEN MICHAEL
IPC: G01S1/76
Filed: 1987-09-09
Abstract: Points, loci and surfaces can be projected in space by sensing the cancellation of polyphasally displaced signals propagated in a sonic medium, emitted from known reference points. In one arrangement an array of four ultrasonic emitters are positioned, one emitter at each corner of an equilateral tetrahedron and each emitter emits signals 90 DEG  out of phase from those of the next emitter. A point is then defined at the centre of the array where a hand-held sensor indicates a null output. The phased cancelling signals are derived from a common reference signal. In another arrangement a line is defined from a triangular array of three emitters, each emitting 120 DEG from the next and a plane may be defined by two emitters, 180 DEG out of phase.
Patent GB-2196460-A (GB)
Title: Voice recognition
Inventor: FUJIMOTO JUNICHIROH
IPC: G10L15/06
Filed: 1987-10-05
Abstract: In voice recognition, pattern matching is used to determine which reference voice pattern has the highest degree of similarity to the input, unknown, voice pattern. It is often the case that an undesired noise component is added at the front or tail end of a voice pattern. If such a noise component is present in only one of the two patterns to be compared, the noise component is eliminated from the pattern containing it or added to the other pattern such that it is absent or present in both of the two patterns to be compared. For example if the reference pattern is as in Fig. 2a and the input pattern as in Fig. 2b the tail end portion of the reference pattern may be omitted, Fig. 2c. If both patterns contain noise components, these components may be compared and the remainder of the patterns compared separately. Similar techniques may be used when combining reference patterns to form a library of stored reference patterns.

Patent GB-2224310-A (GB)
Title: Self-closing door time control
Inventor: DIXON MAURICE GEORGE
IPC: E05F1/00
Filed: 1988-10-04
Abstract: When the self-closing door, e.g. a Fire Door, is opened against spring bias, door-mounted spindle C slides in pivoted stay A until spindle tooth B abuts stay peg T to rotate the spindle and cam disc D. This pivots lever H to depress plunger K of pneumatic timer L. Conic plunger end R is thus moved to part levers O to hold disc D. With door release, tooth B re-engages peg T to stop closure. The door closing force tends to turn spindle C making cam wedges E part levers O to urge cone N to return plunger K. After a pre-set time, timer air has escaped to enable plunger return, and levers O can ride over wedges E to allow tooth B to ride past peg T for door return. The timing device is assisted by the closer, and does not need external power. <IMAGE>

Patent GB-2237706-A (GB)
Title: Radio communications link with diversity
Inventor: GARDNER BRIAN R
IPC: H04B7/06
Filed: 1989-11-03
Abstract: A base station 10 has two transmitting antennas 20, 22 which both transmit the same signal to a mobile station 12, the signal via antenna 22 being delayed by a time delay unit 24 to ensure de-correlation between the transmitted signals. It is unlikely that multi-path fading will occur simultaneously in both signal paths to the single antenna 24 of the mobile station wherein an equaliser 26, such as a Viterbi equaliser, decodes the originally transmitted signal from the two superimposed signals received by antenna 24. Diversity is obtained without the need for two antennas at the mobile station where space limitations would probably prevent this. The base station 10 receives the signal transmitted from the single antenna 24 at the mobile station 12 over two signal paths respectively directed to the two antennas of the base station. The signals received are de-correlated by a time delay 38 connected to one of these antennas and summed, summed 36 and passed to an equaliser 40 for decoding. A repeater station may similarly include time delays (76), (82), (Figs 7, 8), to give de-correlation between the signals it retransmits and the corresponding signals directly transmitted by the base and mobile sections. <IMAGE>
