A system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and / or bit rates. The analyzer of the system divides the input signal in different portions, at least one of which carries information sufficient to provide intelligible reconstruction of the input signal. The analyzer also encodes separate information about other portions of the signal in an embedded manner, so that a smooth transition can be achieved from low bit-rate to high bit-rate applications. Accordingly, communication devices operating at different sampling rates and / or bit-rates can extract corresponding information from the output bit stream of the analyzer. In the present invention embedded information generally relates to separate parameters of the input signal, or to additional resolution in the transmission of original signal parameters. Non-linear techniques for enhancing the overall performance of the system are also disclosed. Also disclosed is a novel method of improving the quantization of signal parameters. In a specific embodiment the input signal is processed in two or more modes dependent on the state of the signal in a frame. When the signal is determined to be in a transition state, the encoder provides phase information about N sinusoids, which the decoder end uses to improve the quality of the output signal at low bit rates.

The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and / or the client applications across connectivity interruptions and / or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

Method and apparatus for operating a motor. During a commutation state current is applied to a motor while field effect transistors (FETs) are held in an enable or disable state to effect current in phases of the motor. The phases have a high FET and a low FET. Control circuitry is employed to detect back electromotive force and zero crossing (Zc) signals that indicate transition timing for the commutation states. At a transition state the current is decreased in accordance with a noninstaneous decay function and applying a pulse width modulated signal to a switching element. Alternatively, the current is decreased by enabling either all low side FETs or all high side FETs to allow the current to decay. The next commutation state is applied after the current has been reduced, avoiding negative current to be source from ground and reducing current spikes in the motor.

Under oscillation-reducing control executed while PWM control is performed, an oscillation-reducing torque that is opposite in phase to a varying component of the motor revolution number is generated and, a final torque command value that is the sum of the oscillation-reducing torque and a torque command value is used to drive an AC motor. In a transition state where the PWM control mode is switched to overmodulation control mode, the oscillation-reducing torque that is determined by multiplying an oscillation-reducing torque by a correction coefficient that varies depending on a modulation factor gradually decreases as the correction coefficient decreases and substantially becomes zero when the control mode is switched. Thus, the oscillation-reducing torque has no stepped portion that occurs in the oscillation-reducing torque when the control mode is switched. Thus, oscillations in output torque of the AC motor can be reduced.

In a cruise assist ECU, when a vehicle drive state is changed from a running state to a state immediately before vehicle stop or from a stop state to a state immediately after vehicle start, a feedback torque gain compensation part changes a feedback torque gain to a second set value, and maintain it during the state immediately before vehicle stop or the state immediately after vehicle start. Because the second set value is smaller than a first set value, a response delay is increased in feedback control of the feedback torque control part when the first set value of the feedback torque gain is switched to the second set value. This makes it possible to slowly change the FB control value during the transition state in elapse of time, and prevent a brake or damping torque generated in the vehicle from being excessively changed in FB control.
