  • Publication number: 20200095800
    Abstract: An apparatus, arrangement and method for remote opening electric door lock of a building. The apparatus (1) comprises control unit (5), a data communication unit (3) and an electrical actuator (6) configured to open the door lock (2) under control of the control unit. The apparatus is mounted at a remote door opening switch (10) and the control unit generates a control signal for the actuator to open the lock in response to receiving at least one authentication signal. The actuator is configured to move a manually operable switching element of the door opening switch and to thereby cause opening of the door lock.

  • Patent number: 7146318
    Abstract: A method for detecting pauses in speech signals is disclosed in which the frequency spectrum is divided into two or more sub-bands. Samples of the signals on the sub-bands are stored at intervals, the energy levels of the sub-bands are determined on the basis of the stored samples, a power threshold value (thr) is determined, and the energy levels of the sub-bands are compared with said power threshold value (thr) . A subband minimum is set and a detection time limit is set so that, in a noise situation, a speech pause can be verified by checking to determine if each pause detected remains for the duration of the detection time limit and if a pause is detected in at least said minimum subbands.

  • Patent number: 7139697
    Abstract: A method for selecting the language for a character sequence fed into a data processing device, wherein decision trees are trained for different characters on the basis of lexicons of predetermined languages. The decision trees describe language probabilities on the basis of characters in the environments of the characters. The decision trees for at least some of the characters of the character sequence fed into the data processing device are traversed, thus obtaining a probability of at least one language for each character. The language for the character sequence is selected on the basis of the probabilities obtained.

  • Patent number: 6965770
    Abstract: A method and system for establishing a dynamic content delivery system (DCDS) is disclosed. In one embodiment, a Bluetooth enabled mobile communications unit is used to communicate with a server in order to make a request for the delivery of specific content, such as a song, video, or the like, to a separate output device, such as a loudspeaker, a display screen, or the like. In another embodiment the content is delivered back to the requesting mobile communications device. In some embodiments, hybrid networks may be used for requesting and delivering content. A narrowband, bi-directional, unicast network may be used for requesting content and acknowledging the requests, while a broadband, unidirectional, multicast network may be used to deliver the requested content to the requesting client device. The order in which the content is delivered may be modified by user requests according to a predetermined algorithm.

  • Patent number: 6721698
    Abstract: A speech recognition feature extractor includes a time-to-frequency domain transformer for generating spectral values in the frequency domain from a speech signal; a partitioning means for generating a first set and an additional set of spectral values in the frequency domain; a first feature generator for generating a first group of speech features using the first set of spectral values; a additional feature generator for generating an additional group of speech features using the additional set of spectral values; the feature generators arranged to operate in parallel, an assembler for assembling an output set of speech features from at least one speech feature from the first group of speech features and at least one speech feature from the additional group of speech features, and an anti-aliasing and sampling rate reduction block, where the first and the additional set of spectral values comprise at least one common spectral value.

  • Patent number: 6707910
    Abstract: The scope of the present invention is a device for detecting the source of a voice, which device comprises microphone means (2; 2a, 2b, 2M) for receiving a voice signal and detecting means for detecting the voice from the received voice signal. The device comprises means (15, 17) for determining the direction of arrival of the received signal, means (17) for storing the assumed direction of arrival of the voice of a certain source and means (18) for comparing the direction of arrival of said received signal with said assumed direction of arrival. The device further comprises means (18) for indicating that the source of the voice is said certain source when the comparison proves that the direction of arrival of said received signal matches with said assumed direction of arrival within a certain tolerance.
