Title: Speech recognition utilising determination of a back-off group of code words in using an acoustic model.
Inventor: CHIN KEAN KHEONG
IPC: G10L15/10
Filed: 2008-09-29
Abstract: A method, apparatus and computer program for speech recognition comprising receiving speech input and using it to predict a sequence of words likely to match the received speech input using an acoustic model and a language model; likelihoods of the predicted sequence of words matching the received speech input output from the 2 models are combined to output a sequence of identified words. The speech input comprises a sequence of observations, a likely sequence of words arising from the sequence of observations is determined using an acoustic model. In the acoustic model each observation is converted into an input vector in acoustic space. The acoustic model represents words as points in acoustic space, each point representing a probability distribution or a probability density function (pdf) of a word. The pdfs may be Gaussians. Within the acoustic model, the probability distributions are clustered to form code words typically using the Gaussian selection method known as Vector Quantization. After selection of a first group of codewords closest to the input vector, a second group of "back-off" code words are determined, these back-off code words being the next closest group of code words to said input vector.

Title: Calculating steam loss by comparison of a vibration signal to a previously generated record that correlates vibration and leakage quantity
Inventor: ELKINS ASHLEY
IPC: G01M3/24
Filed: 2008-12-22
Abstract: A method and apparatus for detecting the amount of steam leaking from part of a steam operating system 1 (e.g. a steam trap 2, 3). Initially, vibration signals indicative of a given quantity of gas leakage in a plurality of regions or apparatuses of the system (e.g. different makes and models of steam traps) are measured or calculated and stored for subsequent access. Thereafter, selected regions may be tested by measuring vibration signals (using detectors 4, 6) and comparing these signals with the corresponding stored signals in order to calculate and indicate to the user the actual quantity of steam-loss at each region. The comparison means may include a look-up table and may either be incorporated with the detector or be remote from it (e.g. in a PDA or in a fixed installation that continuously monitors fixed or moveable detectors situated around the system). Signal analysis may use Time Encoded Signal Processing and Recognition (TESPAR) software.

Title: Cable tightening device having a self-locking function
Inventor: CHANG WEN-CHENG
IPC: B25B25/00
Filed: 2009-02-12
Abstract: A cable tightening device includes a fixed unit 10, and a movable unit 20 mounted on the fixed unit. The fixed unit includes a base 16, a rotation member 30, two ratchet wheels 40, and a stop plate 50. The stop plate has two locking flanges 52 which may be in the form of a trough, channel, hole (51a, Figure 7) or protrusion (51b, Figure 8) movably mounted to the base 16 preferably via a sliding slot 13 which may have a locking face. Each of the ratchet wheels has a plurality of one way ratchet teeth 41 each provided with a locking hook 52 which may be bard shaped capable of being locked onto the respective locking flange of the stop plate. The base may have a stop portion (15, Figure 7) and the movable member 20 may have a stop block (24, Figure 9). Thus, even if the movable unit is removed from the rotation member, each of the ratchet wheels is still locked onto of the stop plate, and the stop plate cannot be detached from the ratchet wheels due to an external pulling force.

Title: Disambiguation of location inputs to a navigation system
Inventor: DUSTERHOFF KURT
IPC: G01C21/36
Filed: 2009-05-18
Abstract: A navigation apparatus performs a location defining process wherein ambiguities in inputted location information are resolved via later inputted location information. The apparatus receives a settlement name S4-3, and searches its map records for settlements matching the received name to create a candidate list location S4-5. If a settlement name is not unique, the map records point to a disambiguation record which defines a tree structure to possible locations arising from the settlement name. The apparatus subsequently receives a road name S4-9, and searches within its map records for settlement and road name combinations matching the received road name for settlements identified in the candidate location list at step S4-11 to create a refined candidate list location. The apparatus may further receive a name / number S4-15, and search within its map records for settlement, road name and name / number combinations matching the received name / number combinations identified in the refined candidate location list at S4-17 to create a final candidate location list. The resolved reduced set of possible combinations may be one or more branches of the tree structure. This reduced set of combinations then constitutes all or part of the final candidate location list S4-19.

Abstract: 331,845. Triggs, W. W., (American Hair if Felt Co.). April 4, 1929., Disinfecting-chambers. - Apparatus in which hair, feathers, and the like are treated with a gaseous agent, for example, deodorized by treatment with ozone, comprises a chamber 1 into which the material is delivered by a pneumatic conveyer 12 so as to pass through a current of ozone or other gas entering through an opening 26<1>. A belt conveyer 27 provided with spikes 29 passes over the floor 3 of the chamber 1, removing part of the material which has been subjected to the action of the gas through an opening 8, and assisting the remainder to circulate. On entering the chamber 1 from the conveyer 12 the material first strikes a baffle plate 14 which serves to protect a screened opening 15 in the opposite wall of the chamber and to deflect the material into the path of the entering gas. In the form shown the treating gas is ozonised air the air being drawn by means of a fan 20 through a pipe 24 and ozonizer 16 to the opening 26<1>. The treated material falls into a hopper 35.

Title: Improvements in or relating to gas control valves for water heaters
Inventor: BROWN HARRY
IPC: F24H9/20
Filed: 1956-04-05
Abstract: 857,783. Valves. PEGLERS Ltd. April 5, 1957 [April 5, 1956], No. 10463/56. Class 135. A water heater fitted with gas burners has means for controlling the flow of gas to the burners of the kind in which a gas control valve is opened by manipulatable means associated with thermostat control means adapted to permit closing of the control valve automatically when the water becomes heated beyond a predetermined value. The thermostat comprises a bi-metal strip 41 housed in a chamber 40 within the water storage vessel 10 of the heater. A rod 42 adjustably connected to the bi-metal strip at 50 coacts with a conical member 51 on a spindle 21 such that when the push-button 20 is depressed to move the spindle 21 to the right, the rod 42 overrides the shoulder of the member 51 and retains the spindle 21 in the actuated position against the action of a return spring 23. The movement of the spindle 21 also causes a lever 29 to ride up the inclined surface of a second conical member 25 to rotate a cam to open the gas control valve (not shown). When the water in the heater reaches a predetermined value, the bi-metal element 41 flexes upwards to withdraw the rod from contact with the conical member 51, thereby permitting the spindle 21 and associated conical member 25, 51 to return to their original positions and the gas control valve to close under its spring bias. The temperature at which the rod 42 is released from contact with the conical member is determined by the setting of the rod 42 relative to the bi-metal strip 41. In another embodiment the member 51 is replaced by a stepped conical member adjustably secured to the spindle 21 such that according to the setting of the conical member the rod 42 engages one of the steps to retain the spindle in its actuated position and the gas control valve in the open position until the bi-metal strip flexes upwards to withdraw the rod. In a further embodiment, instead of a spindle 21 actuated by a pushbutton, a rotatable spindle is substituted which carries two cams, one operating the control valve actuating lever and the other contacting the rod 42, as the spindle is rotated against a spring. The cam contacting the rod 42 is notched for selective engagement with the end of the rod 42 until the bi-metal strip 41 withdraws the rod 42.
