摘要： A method includes determining a first filtered signal based on an audio signal; determining a second filtered signal based on the audio signal; determining, based on the first filtered signal and the second filtered signal, a portion of the audio signal corresponding to a sharp noise; determining, based on the first filtered signal and the second filtered signal, a gain signal that, for the portion of the audio signal corresponding to the sharp noise, has a value that is smaller than a value of the gain signal for the remaining portion of the audio signal; and suppressing, based on the gain signal, the sharp noise from an amplifier input signal determined based on the audio signal.

摘要： A system including first and second gain modules, an operator module, and a priori and posteriori modules. The first gain module applies a non-linear function to generate a gain signal based on an amplitude of a first speech signal and an estimated a priori variance of noise included in the first speech signal. The operator module generates an operator based on the gain signal and the estimated a priori variance of noise. The a priori module determines an a priori signal-to-noise ratio based on the operator. The posteriori module determines a posteriori signal-to-noise ratio based on the amplitude of the first speech signal and (ii) the estimated a priori variance of noise. The second gain module: determines a gain value based on the a priori signal-to-noise ratio and the a posteriori signal-to-noise ratio; and generates, based on the amplitude of the first speech signal and the gain value, a second speech signal that corresponds to an estimate of an amplitude of the first speech signal, where the second speech signal is substantially void of music noise.

摘要： To limit motion in an electromechanical system, an input signal is filtered using an adaptive filter, such as an infinite impulse response filter, to yield a predicted motion, and the input signal is attenuated by an amount controlled by the predicted motion. The filtering may further yield a predicted temperature, and the amount of attenuating may be further controlled by that temperature. Components of the input signal at selected frequencies may be removed, and a portion of the input signal from which the components have been removed may be mixed with a portion of the input signal from which components have not been removed. The removing of components at selected frequencies may include applying a notch filter, and the two portions may be equalized. phase-adjusting the unfiltered portion to account for phase delay introduced by the notch filter. The notch filter may operate at a resonant frequency of the system.

摘要： In an apparatus for receiving and forwarding data packets on a network, a network device includes a plurality of ports for coupling to the network and for transmitting packets to devices disposed in or coupled to the network. At least one processor configured to process packets received via the network processes packets by selectively forwarding processed packets to one or more of the ports. A plurality of queues are defined in a memory, each configured to store packets to be transmitted by ports in the plurality of ports. A queue manager is configured to selectively assign a subset of the plurality of queues to a subset of the plurality of ports.

摘要： Aspects of the disclosure provide an apparatus that includes a navigation signal receiver and a processing circuit. The navigation signal receiver is to receive, from a plurality of satellites, first ephemeris data. The first ephemeris data is effective for a first time duration. The processing circuit is to predict, based on the first ephemeris data, second ephemeris data. The second ephemeris data is effective for a second time duration that is extended beyond the first time duration. The second ephemeris data is used by the navigation signal receiver to acquire satellite signals for positioning the apparatus during the second time duration.

摘要： An apparatus includes a clamp control circuit configured to control a first current to have a magnitude substantially equal to that of a second current when the second current has a first flow direction. The clamp control circuit is configured to control the first current to be substantially zero when the second current has a second flow direction. A method includes determining a value of a first current, controlling a second current to have a substantially zero value when the first current flows in a first direction, and controlling the second current to have a magnitude substantially equal to that of the first current when the first current flows in a second direction. The first current flows in the first direction when a winding of a motor is being supplied with energy and flows in the second direction when the winding of the motor is discharging energy.
