  • Patent number: 11615203
    Abstract: A record management system stores records for an organization having a plurality of members and a plurality of groups, and manages accessibility of the records for the organization according to a specified record access policy. The record management system generates an accessibility database that indicates, for each member, records that are explicitly or implicitly accessible by each member such that the records accessible for each member can be quickly determined if needed. A member has explicit access to a record if there is an explicit indication of accessibility between the member and the record. A member has implicit access to a record through membership associations to other members or groups that have access to the record. The record management system also receives search queries from members and returns records that are relevant and accessible to the members based on the accessibility database.

  • Patent number: 10763651
    Abstract: A cable stripping tool is provided for making a circumferential or ring cut and a spiral cut in the jacket of a cable. A cutting blade of the tool includes first and second blade portions which are integrally formed with each other and are angled relative to each other. In use, after the cutting blade penetrates the jacket, the tool is rotated in a first direction and the first blade portion cuts the jacket to form a ring cut. The tool is then rotated in a second, opposite direction and the second blade portion cuts the jacket to form a spiral cut. Thereafter, the tool is rotated in the first direction and the first blade portion cuts the jacket to form a ring cut. The cuttings by the blade portions are done without disengaging the cutting blade from the cable.

  • Publication number: 20120230501
    Abstract: The present invention provides an auditory test and compensation method for an audio system comprising an audio device coupled to an audio output means and a listener of the audio device. The method comprises the steps of: delivering a series of audio stimuli through the audio output means; capturing a listener's response to the audibility of the stimuli; calculating a compensation print from the frequency response; deriving a filter from the calculated compensation print with respect to the frequencies associated with the frequency response and applying the filter to an audio signal of the audio system.

  • Publication number: 20090268962
    Abstract: The Direction of Arrival estimation algorithm ESPRIT is capable of estimating the angles of arrival of N narrowband source signals using M>N anechoic sensor mixtures from a uniform linear array (ULA). Using a similar parameter estimation step, the DUET Blind Source Separation algorithm can demix N>2 speech signals using M=2 anechoic mixtures of the signals. The present invention demixes N>M speech signals using M>=2 anechoic mixtures.

  • Patent number: 7474756
    Abstract: A system and method for non-square blind source separation (BSS) under coherent noise. The system and method for non-square BSS estimates the mixing parameters of a mixed source signal and filters the estimated mixing parameters so that output noise is reduced and the mixed source signal is separated from the noise. The filtering is accomplished by a linear filter that performs a beamforming for reducing the noise and another linear filter that solves a source separation problem by selecting time-frequency points where, according to a W-disjoint orthogonality assumption, only one source is active.

  • Patent number: 7302066
    Abstract: A method is presented for eliminating an unwanted signal (e.g., background music, interference, etc.) from a mixture of a desired signal and the unwanted signal via time-frequency masking. Given a mixture of the desired signal and the unwanted signal, the goal of the present invention is to eliminate or at least reduce the effects of the unwanted signal to obtain an estimate of the desired signal.

  • Patent number: 6954494
    Abstract: A method for blind source separation of sources detects the sources using sensors to obtain representative data. The data is then represented by two mixtures having estimates of amplitude and delay mixing parameters. The estimates are updated, including: calculating error measures, each indicating a closeness of the estimates for a given source to a given time-frequency point in the mixtures; and revising the estimates, based on the error measures. The mixtures are filtered to obtain estimates of the sources, including: selecting one error measure having a smallest value in relation to any other error measures, for each time-frequency point in the mixtures; and leaving unaltered any time-frequency points for which a given error measure has the smallest value, while setting to zero any other time-frequency points for which the given error measure does not have the smallest value, for each error measure. The estimates of the sources are output.

  • Patent number: 6526148
    Abstract: A delay and attenuation compensation-based BSS technique for source selection and noise reduction is provided for speech recognition applications. The undesired signals are attenuated in every situation and from every direction as much as possible. For this purpose, the direction of the input signals is determined. Depending on the direction of the undesired signals, the internal delay between the microphones is calculated. This internal delay is then used in subtracting the microphone signals from each other. Therefore, the invention gives not only a good directionality on average, but the best directionality for every listening situation. Furthermore, the channel selection problem is solved in conjunction with the BSS technique.
