摘要： Sub-band filtering, adaptive echo cancellation, and residual echo suppression are selectively and separately applied in hierarchical order under the control of a circuit that monitors four separate signals to determine n machine states. The number of machine states is further divided among m levels of noise in determining which, and how much of, sub-band filtering, adaptive echo cancellation, and residual echo suppression to use at any given time. A voice activity detector (VAD) is used to monitor each signal and provides statistical information in addition to whether or not a voice signal is detected. Sub-band filter, echo cancelling, and non-linear processing are not permitted to provide maximum reduction simultaneously. Even so, the invention provides at least 15 dB more echo suppression than systems without a sub-band filter bank series coupled with a non-linear processor in each channel.

摘要： A system for processing audio signals in two channels, wherein each channel includes a plurality of band pass filters for dividing the signal in each channel into a plurality of bands and a plurality of variable gain amplifiers coupled one each to a band pass filter. Control logic coupled to the variable gain amplifiers prevents the signals in adjacent bands within a channel from being attenuated simultaneously. The control logic attenuates the signals in one channel in accordance with the signal in the corresponding bands in the other channel. In some circumstances, the signal in the band in the one channel is attenuated.

摘要： A complementary comb filter includes a plurality of band pass filters and a plurality of notch filters, wherein the notch filters have the same center frequencies as the band pass filters or the same center frequencies as the dead bands defined by the band pass filters. Phase distortion by the notch filters occurs primarily in the notch, thereby eliminating distortion of the signal.

摘要： A band pass filter includes a pair of filters having different center frequencies and a difference amplifier coupled to the outputs of the filters. The filters preferably have response curves that intersect at −3 dB. The separation of the center frequencies determines, in part, the ripple in the response curve of the band pass filter.

摘要： A remote control unit includes an RF transceiver that complies with a Bluetooth® standard and an RF transmitter that does not comply with the Bluetooth® standard, whereby the remote control unit serves as a wireless gateway between Bluetooth® compliant devices and the hearing aid. The hearing aid can further include a transmitter and the remote control unit can further include a receiver, neither of which comply with the Bluetooth® standard. The transmitters operate in the ISM band at low power, minimizing power dissipation within a hearing aid.

摘要： A system for positioning a solar panel includes a first frame and a second frame substantially parallel with the first frame. A plurality of tubes intersect the first frame and extend through the second frame. Each tube has a free end and a distal end. A photovoltaic device attached to the free end of each tube and the distal end is coupled to the first frame. Relative motion of the frames tilts the tubes and the photovoltaic devices, thereby permitting the photovoltaic devices to track the sun during the day.
