Patent GB-2209418-A (GB)
Title: Analysing transitions in finite state machines
Inventor: LLOYD ALEXANDER HOWARD
IPC: G06K9/62
Filed: 1988-10-19
Abstract: In speech recognition words to be recognised may be represented by finite state machines and recognition is based on analysing transitions through the machines as an utterance occurs. One value which is required for each state of each machine is minimum cumulative distance; that is the smallest value on reaching one of the states from a starting position, considering all possible paths. Since words are spoken one after another, a finite state machine representing one word has transitions to another machine representing another word. The network of such transitions is complex and varies between different pairs of words. In the present invention, rather than use such a network, each finite state machine is given a start state (SD) at the beginning and an end state (ED) at the end. A Viterbi engine finds the minimum cumulative distance for each normal state of each machine and also determines the minimum cumulative distance for each end state. Traceback pointers for each end state are determined which indicate the number of transitions traversed in reaching that end state. A further distance dependent on the traceback pointer for each end state is added to that state to form a word ending score. The best score is then used to update start states selected on a grammatical basis, other start states being updated with a maximum value. <IMAGE>

Patent GB-894920-A (GB)
Abstract: 894,920. Pulsing carrier frequencies. STANDARD TELEPHONES & CABLES Ltd. Oct. 2, 1959 [Oct. 6, 1958], No. 33482/59. Class 40(5). A klystron or other R.F. amplifier or oscillator is pulsed by applying to an electrode 2 a sloping linear step wave from across a capacitor 12 charged at a constant rate through a valve 4 from a pulse generating monostable circuit 11, then detecting the output at 14 and deriving from it a restoring pulse which cuts off the first pulse source 11 and operates simultaneously a second pulse generating monostable circuit 19 which discharges the capacitor 12 at a constant rate from a valve 5 series connected with the valve 4 to produce an oppositely sloping linear step wave forming with the first a triangular modulation pulse. Transferred through the R.F. amplifier this becomes a pulse of gaussian envelope i.e. narrow bandwidth. The restoring pulse may be derived by differentiating twice at 15, 16 the detected output (from a directional coupler 13), then adjustably delaying at 17 the resultant wave and passing at 18 only a negative going control pulse to the first pulse source 11 which, on being cut off, renders operative the second source 19. The pulse signalling may be used in TACAN or LORAN air navigation systems.

Title: Limited slip differential having planetary gears acting as gear pumps
Inventor: KOERNER TILLMANN
IPC: F16H48/20
Filed: 1990-09-18
Abstract: With a differential gearing having a spur gear construction, planetary compensating gears (31a, 31b) are installed in inter-meshing pairs and are tightly enclosed by a housing (14) so that with meshing spur gears (22, 23) they can act as toothed pumps with pressure zones, with a locking moment being produced between the two driven shafts. A substantial increase in the locking moment is achieved in that the compensating gears constructed as pin ions are disposed in a determined sequence on the circumference of the spur gears and also comprise along their face width partitions (32) which prevent a reduction in pressure along the toothing. As a result with an equal number of pinion pairs there is produced a number of pressure zones which is more than double and consequently there is an increase in the locking moment developed. <IMAGE>
