Title: Identifying sounds and reducing false positive identification of sound
Inventor: MITCHELL CHRISTOPHER JAMES
IPC: G06N20/00
Filed: 2008-12-15
Abstract: The invention is a digital sound identification system, the system comprising non-volatile memory for storing a Markov model, a stored program memory storing processor control code, a sound data input, a processor coupled to said sound data input, to said working memory and to said stored program memory for executing said processor control code. The processor control code comprises code to input, from said sound data input, first sample sound data for a first sound to be identified, said first sample sound data defining first sample frequency domain data, said first sample frequency domain data defining an energy of said first sample in a plurality of frequency ranges; generate a first set of mean and variance values for at least a first Markov model of said first sample sound from said first sample frequency domain data; store said first Markov model in said non-volatile memory; input interference sound data defining interference frequency domain data and adjust said mean and variance values of said first Markov model using said interference frequency domain data. The code inputs third sound data defining third sound frequency domain data, determines a probability of said third sound frequency domain data fitting at least said first Markov model and output sound identification data dependent on said probability. The invention aims to reduce false positive identification of sound by using a sample of background or interfering sound to adjust man and variance parameters characterising probability distributions associated with states of the Markov model. It has its application in baby monitors, CCTV, intruder systems and home care help systems.

Title: Improvements in or relating to alarums or warning mechanisms
IPC: G04C23/16
Filed: 1945-04-26
Abstract: 621,780. Electric alarm-clocks. OCKLESHAW, J., and BURGESS, F. W. April 26, 1945, No. 10491. [Class 139] [Also in Group XXXVII] An alarm clock which is arranged normally to enable an alarm device to function at regular or predetermined intervals has means operable to cancel the operation of the alarm device when it is next due to function said means being always released from its operative position at a predetermined time irrespective of the times set for operation of the alarm device. A wheel j rotated by the clockwork once in twentyfour hours is provided with two pins m and y the former of which is cammed at its forward end. A blade spring d constantly urges the pin m against the adjacent face of a manually rotatable disc n which has a recess q. The arrangement is such that when the pin m coincides with the recess q which has, been manually set to a definite angular position the blade spring d causes axial movement of the wheel j to push the pin m into the recess q. A contact f on the blade spring d abuts a contact g on another blade spring e to close an electric circuit and cause operation of an alarm. The alarm can be stopped or cancelled by depression of a button t the foot of which is provided with a cone u which separates the blade springs d and e thereby opening the circuit. The cone u is held in this operative position by the leg v of a pivoted latch x until the pin y on the wheel strikes the other leg of the latch x and releases the cone u. This release therefore takes place at the same time every day. If the button t is rotated at any time during the alarm, a cam t<SP>5</SP>, above the cone u, abuts the arm v of the latch x and causes release of the cone u which is moved upwardly by a spring t<SP>2</SP>.

Abstract: 294,190. Bauer, W. S., (Gilmont Products Corporation). April 20, 1927. Filling concentric collapsable tubes. - Concentrically arranged collapsable tubes are filled by first inserting paste 16 in an outer tube 10 to a level determined by the size of the inner tube, and then inserting the inner tube 17 which causes the paste to rise and fill the outer tube. The inner tube is carried by a mandrel 21 formed with a projecting portion 22 adapted to pass through the nozzle 19 of the inner tube and prevent entry of the paste 16 into the tube as the tube passes down through it. Fins 20, formed on the nozzle 19 of the tube 17 frictionally engage in a recess 15 in the outer tube 10 to secure the inner tube in place, whereupon the inner tube is filled and the upper open ends of the tubes are closed in the usual manner. The outer tubes may be supported in holders on an endless chain moved intermittently and adapted to bring a holder to rest first beneath a filler which partly fills the outer tube with paste, then beneath a mandrel carrying an inner tube which it inserts in the outer tube, then beneath a filler for the inner tube and finally beneath a folding over or cleating device for closing the tubes.
