  • Patent number: 12142939
    Abstract: Methods and devices for surveying for active and inactive power receivers within a wireless-power coverage area are described. A method includes causing performance of a survey looking for active power receivers within a wireless-power coverage area using communication radio(s). Information is received from an active power receiver and transmission of RF signals is caused to energize inactive power receivers using a power-transmission antenna. A first RF signal is transmitted using a first value for a transmission characteristic, and a second RF signal is transmitted using a second value for the transmission characteristic. Additional information is received from a first energized power receiver and further information from a second energized power receiver. Two or more frequency bands are identified for radio-frequency wireless-power transmissions by a wireless-power transmitting device within the wireless-power coverage area based on the information, the additional information, and the further information.

  • Patent number: 6415252
    Abstract: Bits are allocated to short-term repetition information for unvoiced input signals. Stated differently, more bits are allocated for pitch information during unvoiced input speech than in the prior art. The improved method and apparatus in an encoder (300) and decoder (700) result in improved consistency of amplitude pulses compared to prior art methods which indicates improved stability due to increased search resolution. Also, the improved method and apparatus result in higher energy compared to prior art methods which indicates that the synthesized waveform matches the target waveform more closely, resulting in a higher fixed codebook (FCB) gain.

  • Patent number: 6236960
    Abstract: An improved speech coder takes advantage of the fact that any given pulse combination can be uniquely described by the following four properties: number of degenerate pulses, signs of pulses, positions of pulses, and pulse magnitudes. In accordance with the invention, a four stage iterative classification of the pulse combinations, where each stage groups the pulse combinations by one of these four properties, is performed. The process starts with the number of pulses, then determines the total number of possible sign combinations, pulse position combinations, and pulse magnitude combinations. This flexibility allows for the sign combinations to be grouped in the last stage. Since the number of sign combinations is always a power of two, leaving the sign combinations for last along with appropriately ordering the elements in the previous three stages allows the signs to be coded by independent bits, in turn allowing for error protection of those bits.

  • Patent number: 6141638
    Abstract: A speech coder (400) for coding an information signal varies the codebook configuration based on parameters inherent in the information signal. The speech coder (400) requires no additional overhead for sending of mode parameters while allowing subframe resolution. The configurations vary not only for voicing level, but also for pitch period since different physiological traits yield different codebook configurations. A dispersion matrix (406) within the speech coder (400) facilitates a codebook search which is performed on vectors whose length can be less than a subframe length. Additionally, use of the dispersion matrix (406) allows the addition of random events for very slightly voiced speech which incurs little computational overhead but produces a rich excitation.

  • Patent number: 6113653
    Abstract: An open-loop delay contour estimator (204) generates delay information during coding of an information signal. The delay contour is adjusted according to an error minimization criterion on a subframe basis, which allows a more precise estimate of the true delay contour. A delay contour reconstruction block (211) uses the delay information in a decoder in reconstructing the information signal.
