Title: Linear predictive coding based acoustic echo cancellation
Inventor: GOUBRAN RAFIK
IPC: G10L21/02
Filed: 2000-12-12
Abstract: Handsfree telephony continues to be an increasingly desirable feature of modern telecommunications, whether in a conference room or mobile setting. Fundamental to the user acceptability of these systems is the performance of algorithms for acoustic echo cancellation, the purpose of which are to prevent the far-end signal from being transmitted back to the far-end talker. Most speech coding algorithms are based on some variant of Linear Predictive Coding (LPC), which reduces the amount of bits sent across a channel. Instead of doing echo cancellation in the time domain, the invention involves operating an acoustic echo canceller on the LPC parameters at the receiver, before the decoding stage. Data which has undergone this transformation is in a form more amenable to echo cancellation. Specifically, the removal of signal correlation through the LPC process improves the convergence properties of adaptive filters using simple adaptation algorithms such as the Least Mean Square (LMS) algorithm. In addition, the echo cancellation process and coding process can share some of the computation processing load since the domain transformation is already part of the coding stage.

Title: Method and apparatus for fastening identification labels to wood products
Inventor: HARCUBA MIROSLAV
IPC: G09F3/04
Filed: 2001-03-02
Abstract: A method and apparatus are disclosed for applying identification labels on wooden products. A fastening system where a plastic label marked by a bar code or other identification method is picked up by vacuum onto the applicator tool which will insert forcibly edges of the identification label into the wooden product to remain permanently wedged in the indentation. During subsequent cutting of the wooden product into which is attached identification plastic label there will be no danger from dislodged or fragmented metal staples as is presently the case.   Another method is described where soft pliable plastic identification label is being picked up by the vacuum onto the applicator apparatus which is equipped with punches that will punch strips of hard plastic and push cut disks from the hard plastic over the soft pliable plastic label into the wooden product. Hard plastic disks will remain permanently wedged into the formed hole and secure the soft pliable plastic label to the wooden product. During subsequent cutting of the wood when the label is cut it will not present danger to the operator or the bystanders.

Abstract: Multiple, yet plausible, pronunciations of a proper name are generated based on one or more potential language origins of the name, and based further on the context in which the name is being spoken -- namely, on characteristics of the population of potential speakers. Conventional techniques may be employed to identify likely candidates for the language origin of the name, and the characteristics of the speaker population on which the generation of the pronunciations is further based may comprise, for example, the national origin of the speakers, the purpose of the speech, the geographical location of the speakers, or the general level of sophistication of the speaker population. Specifically, a method and apparatus is provided for generating a plurality of plausible pronunciations for a proper name, the method or apparatus for use in performing speech recognition of speech utterances comprising the proper name by individuals within a given population of speakers, the method or apparatus comprising steps or means respectively for (a) identifying one or more of a plurality of languages as a potential origin of the proper name; and (b) generating a plurality of plausible pronunciations for the given proper name, one or more of the plurality of pronunciations based on the one or more identified languages, and the plurality of plausible pronunciations based further on one or more characteristics associated with the given population of speakers.

IPC: B60R16/023
Filed: 2001-08-31
Abstract: A device for easily determining whether a rare short circuit, which results from the generation of heat exceeding a predetermined value, has occurred in a load circuit. The device includes a fuse for detecting a load current that flows through the load circuit and generates a detection signal. A determination circuit is connected to the fuse to determine whether a rare short circuit has occurred. The determination circuit calculates one of a first parameter and a second parameter based on the detection signal. The first parameter relates to a first time period during which the load current exceeds a predetermined reference current value. The second parameter relates to a second time period during which the load current is less than or equal to the predetermined reference current value. The determination circuit cumulates one of the parameters every predetermined time interval to calculate a cumulative parameter value and determines whether a rare short circuit has occurred based on the cumulative parameter value.

Abstract: A method and apparatus for increasing the probability of successful data frame transmission from a transmitter to a receiver. When a data frame is generated by a processor (210), it is stored in a transmit queue (212) and a copy of the data frame is stored in a secondary queue (214). An elapsed time device (220) tracks the elapsed time that the data frame copy has been stored in the secondary queue (214). When no data frames are generated by the processor (210), data frame copies from the secondary queue (214) are placed into the transmit queue (212), thereby increasing the redundancy of transmitted data frames and thus the probability of successful transmission to the receiver.

Inventor: KNAPP ALFONS
IPC: G05D23/13
Filed: 2000-07-29
Abstract: A new use of a flow rate regulating device (5, 6) is disclosed whose feature consists of the fact that, when inserted in a water pipeline, it permits the passage of a flow of water having a substantially constant flow rate and predetermined in keeping with the variation within certain limits of the pressure at which the water is supplied to the device, thus constituting a variable resistance that is opposed to the water flow. The new use is especially designed to perform the function of reducing the temperature peak presented by the mixed water drawn from a thermostatic mixing device (1) during the transitory period of regulation when the pressure of the water supplied to one of the inlets (2, 3) of the thermostatic mixing device (1) varies abruptly with respect to the pressure of the water supplied to the other inlet of the thermostatic mixing device (1). The new use consists of the insertion of the flow rate regulating device (5, 6) in the passage of at least one of the flows of supply of cold water and hot water (inlets 2, 3) directed to the thermostatic mixing device (1). The flow rate regulator (5, 6) can be inserted on the passage of both supply flows of cold and hot water, of the hot water supply flow only, or, and preferably, of the cold water supply flow only.
