Title: Multi-tap oversampling filter
Inventor: SADJADIAN AHMED
IPC: H03H17/06
Filed: 1992-05-21
Abstract: A multi-tap oversampling filter for oversampling input data by an oversampling factor of m x n (where m and n are integers) is described. The filter coefficients of the multi-tap oversampling filter 9(c) are defined by a convolution of the coefficients of a first oversampling filter 9(a) having an oversampling factor of m with the coefficients of a second oversampling filter 9(b), where the second oversampling filter has an oversampling factor of and has m-1 fixed-value coefficients (preferably zeroes) inserted between adjacent filter coefficients. <IMAGE>

Title: Magnetic sound mixer.
Inventor: NOBLE PETER
IPC: G11B31/00
Filed: 1992-06-02
Abstract: Live sound A from a microphone is applied to inductive device 1. Magnetic induction is used to mix the live sound from the microphone with sound recorded on a tape 2 by influencing the playback head 3. There is no electrical connection between the tape player and the microphone and so the mixer can be formed as a compact, separate unit (see Fig. 2). The mixer may be used in a Karaoke system. <IMAGE>

Title: Automatic feature detection and side scan sonar overlap navigation via sonar image matching
Inventor: HALEY PAUL HUNTER
IPC: G01S7/539
Filed: 1992-09-18
Abstract: A method of locating objects in sonar images so that matching algorithms can be used to determine if the same objects appear in two images. Information from the matching algorithms can then be used to upgrade the position of the vehicle and objects recorded in the vehicle's navigation system. Images are improved by normalizing brightness and contrast and then convolving the image with at least one filter. The image is normalized by dividing the image into vertical strips, creating a histogram to represent the grayness values for columns of pixels in each strip and applying an algorithm to each strip to change its grayness value.

Title: Laser beam converter
Inventor: PEPLAR DAVID ALLAN
IPC: G02B27/09
Filed: 1993-05-07
Abstract: A laser beam with non uniform intensity profile is given a uniform intensity profile by passage through a principal focusing lens and a phase zone plate array having a random two dimensional array of close packed diffracting Fresnel type zone plates 17, 19 and modified by having the radii of the concentric annuli proportional to the square root of whole numbers and the spaces between the annuli alternatively arranged to cause a phase delay of 0 or  pi  radians. Half of the plates have a central zone 16 of 0 radius phase delay and the other half a central zone 18 of  pi  radius phase delay. The focal length of the zone plates, which can be circular or elliptical, may be varied at random across the phase zone plate array. For use in laser fusion, heat treatment, plasma interactions, or generation of X-rays the phase zone plate array is placed either before or after the principle focusing lens and this combination is placed between the laser source and a target which, to achieve a uniform focal spot profile intensity, is placed slightly out of focus. <IMAGE>

Title: Adjusting clearance between flow straighteners and a compressor rotor.
Inventor: DEROUET PATRICK ROGER JEAN
IPC: F01D17/16
Filed: 1993-10-06
Abstract: Adjustment of the clearance between the variable pitch flow straighteners 1 and the rotor 8 of a compressor (eg. a turbojet high pressure compressor) is effected automatically and jointly with the adjustment of the pitch angle A of the flow straighteners 1. For this purpose each flow straightener 1 has at least one peg 15A slidably mounted in an oblique groove 16A of a bush 13A which is rigidly connected to the stator 2 and relative to which each flow straightener is rotatably mounted. A pivotal movement of each flow straightener 1 thus brings about a systematic modification of the clearance J1. In an alternative arrangement (figure 3) a adjustable stop (20) is also linked to the pitch change mechanism for the flow straightener, whereby it can be moved linearly to adjust clearance between the rotor blade tips (6A) and the stop (20). <IMAGE>

Patent GB-2277213-A (GB)
Title: Vehicle electrical generating system
Inventor: SKELHON ALAN RAYMOND
IPC: H02J7/14
Filed: 1994-04-14
Abstract: An electrical generating system has a three phase alternator which includes a stator winding (15) and a diode rectifier (14) for providing a rectified DC output voltage. A voltage regulator (22) regulates the output voltage of the stator winding (15). A transformer arrangement (33) is also provided having a primary winding (32) coupled to the stator winding by a switch (38), a first secondary winding (34) which provides a stepped up output voltage through a rectifier (40) of typically 110V or 220V DC, and a second secondary winding (36) which provides a regulating voltage for the voltage regulator (22). The latter can be switched either to the rectifier (42) or to field diodes (20) and stator winding (15) by way of a switch (28). In normal operation, the switch (38) is open and the voltage regulator (22) regulates the voltage of the stator winding (15). However, for providing a high level DC voltage, switch (38) is closed and the regulator (22) switched to the rectifier (42). The arrangement allows a simple modification to the existing regulator circuit and minor connections from the transformer arrangement to the alternator stator winding terminals to enable a conventional alternator (eg. on an emergency service vehicle) to be converted simply and quickly to provide a higher DC output voltage (eg. to power floodlighting at accident or incident scenes). <IMAGE>

Title: Foot-measuring apparatus
Inventor: TROMAN DAVID
IPC: A43D1/02
Filed: 1994-11-02
Abstract: A foot placed on the platform (18) is contacted by two driven pairs of opposed calipers viz heel and toe calipers (26, 28) and width calipers (30, 32). The calipers are carried for relative movement by respective pairs of carriages (21, 23 and 31, 33) having a rolling engagement (25, 35) with corresponding longitudinal and transverse guideways (34, 36). Carriages (31, 32) and guideway (36) are carried by the toe carriage (23). Carriages of each pair have a motor driven rack and pinion connection (42, 43 or 49, 53) and sequential contact operation of each pair of calipers is effected by the pinion first driving the rack and then travelling along it. This is obtained by either pre-loading rolling engagement (25 or 35) with the guideway (34 or 36) whereby one caliper moves before the other, or alternatively spring loading (80, 88) one carriage (21 or 31) so that it immediately moves on motor drive of the rack (42 or 49). Potentiometers (41, 51) driven by respective racks (42, 49) transmit data to a processor for LED display of shoe size and width fitting. <IMAGE>

Title: Monitoring the integrity of alarm systems
Inventor: NELSON DOUG
IPC: H04M11/04
Filed: 1995-05-18
Abstract: Remote alarm stations 1-4 connected to a central monitoring station 11-14 via telephone lines 5 are caused to send a telephone call to the central station for system integrity checking, the central station having a calling line identifier 12 so that the calling line can be identified without answering the call, whereby no call charges are incurred during the system checking. In a first system, each remote station sends such a test call to the central station at predetermined times, eg. at regular intervals, known to the central station. In a second system, the remote stations generate the test calls in response to being polled by the central station. The central station distinguishes between test calls and genuine alarm calls by monitoring the duration or relative timing of the call. Thus, in the first system the remote station may only stay on line for one ring in the case of a test call, but may stay on line until the central station answers a genuine alarm call, and in the second system any call which is not in response to polling is deemed to be an alarm call.
