Title: A pattern recognition method
IPC: G10L15/00
Filed: 1981-09-18
Abstract: In a machine implemented voice recognition method, as a first step speech signals are analyzed for feature vectors which are used to compare input signals with prestored reference signals. Patterns of any suitable form are used to calculate a similarity distance measure dIJ which is tested against a threshold to select likely candidates as a first step. A second step selects the most likely candidate by using "common nature" parameters of phonemes such as relative occurrence. Five embodiments of the second step are disclosed, each using a "common nature" criteria of inference to infer (select) the most likely candidate: (1) d'I=W1,.W2.W3 where W is a weighting factor; (2) d''I=CId'I where CI is a correction factor; (3) max p(i,j) where p(i) is the probability of occurrence of the ith phoneme; (4) min d'ij as a variation of max p(i,j); and (5) N(i) is the numerical similarity of the common characteristics of the selected candidates.

Title: Intruder probe
Inventor: ORMANDY LESLIE
IPC: G08B13/08
Filed: 1982-10-27
Abstract: Housing 10 is attached adjacent a surface whose movement is to be monitored, e.g. a pane of glass 31 in a window 30. Pivoted, spring loaded arm 12 extends from housing 10 and its tip 21 impinges on the surface 31. If said tip 21 is moved upwards or downwards more than about 0.5 to 1.0 cm e.g. by breakage of the glass 31 or opening of the window, the other end of the arm 12 within the housing 10 causes actuation of microswitch 11 which is connected to an alarm system. This may be accomplished by a block attached to the end of arm 12 pivoting about a pin so that a corner edge depresses a strip and thereby a button of microswitch 11. The probe is easy to install, not readily susceptible to false alarms and as it is visible may act as a deterrent to potential intruders. <IMAGE>

Title: Tube extractor
Inventor: FILER BURT KISHLAR
IPC: B25B27/02
Filed: 1983-10-13
Abstract: A tube extractor comprises a piston 13 movable within a cylinder 10 by a supply of fluid through a port 14, a broach member 50 secured to the piston 13 to move therewith, and a mandrel 60 secured to a clutch cage 63 of a clutch means 63, 70, 80 and kept stationary by a stationary clutch sleeve 70 engaging the cage 63 through balls 65 during the initial movement of the piston 13. Thus, a part 61 of the stationary mandrel 60 expands the teeth 51 of the broach member 50, during the initial movement, into the tube to be extracted from the sheet of a heat exchanger. Immediately thereafter an inner clutch sleeve 80 of the clutch means, pushed along by the piston 13, receives the balls 65 in its groove 82 thereby disengaging the sleeve 70 from the cage 63 and connecting said cage with the moving piston 13. Whence, further movement of piston 13, broach member 50 and inner sleeve 80 is transmitted to mandrel 60 via its connected cage 63. The mandrel 60 retracts along with members 13, 50 and 80 to extract the tube. <IMAGE>

Title: An improved optical fibre ribbon structure
Inventor: TAYLOR JOHN EDWARD
IPC: G02B6/44
Filed: 1984-06-18
Abstract: An optical fibre ribbon structure suitable for use in an optical cable or other application where there is a risk that optical fibres will be subjected to a tensile force comprises a plurality of optical fibres (1) and flexible reinforcing elements (2) of resilient material arranged side by side and embedded in an elongate plastics body (3). Each resilient reinforcing element (2) is set in such a form that the ribbon structure follows a path of smoothly curved undulations (4) whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure. When the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the resilient reinforcing elements thereby reducing the tensile force otherwise applied to the optical fibres (1). When the tensile force is removed, the ribbon structure returns towards its original undulating form.
