The housing is a cylinder with a special-shaped surface inner cavity, an inlet and an outlet, and the special-shaped surface inner cavity is formed by combining a circular arc surface with a non-circular arc surface. The rotor comprises a rotor body and two pairs of combined sliding plates, wherein the rotor body is a column body processed with a transmission shaft, a centering shaft and crisscross guide grooves, and the combined sliding plates are mounted in the guide grooves. The cover plates are flat plates processed with bearing holes. The two end surfaces of the housing are matched with the cover plates for constituting a sealed cavity. In the sealed cavity, the rotor is matched with the bearing holes on the cover plates through the transmission shaft and the centering shaft. External driving force couple is acted on the transmission shaft so as to enable the rotor to rotate. When the rotor rotates, the non-circular arc surface of the special-shaped surface inner cavity can enable the two pairs of the combined sliding plates to slide in a cross manner so as to suck in fluid from the inlet and press out the fluid from the outlet. When the rotor rotates one cycle, four standard volumes are formed in a cavity body and the equal quantity of the fluid flows by the cavity body when the rotor rotates every one cycle. The flow rate of the fluid is metered by counting the number of rotation cycles of the rotor. 11231222122211122267671.

A personal audio device, such as a wireless telephone, generates an anti-noise signal from an error microphone signal and injects the anti-noise signal into the speaker or other transducer output to cause cancellation of ambient audio sounds. The error microphone is also provided proximate the speaker to provide an error signal indicative of the effectiveness of the noise cancellation. A secondary path estimating adaptive filter is used to estimate the electro-acoustical path from the noise canceling circuit through the transducer so that source audio can be removed from the error signal. Noise bursts are injected intermittently and the adaptation of the secondary path estimating adaptive filter controlled, so that the secondary path estimate can be maintained irrespective of the presence and amplitude of the source audio. 1. A personal audio device , comprising:a personal audio device housing;a transducer mounted on the housing for reproducing an audio signal including both source audio for playback to a listener and an anti-noise signal for countering the effects of ambient audio sounds in an acoustic output of the transducer;an error microphone mounted on the housing in proximity to the transducer for providing an error microphone signal indicative of the acoustic output of the transducer and ambient audio sounds at the transducer;a noise source for providing a noise signal; anda processing circuit that generates the anti-noise signal to reduce the presence of the ambient audio sounds heard by the listener in conformity with an error signal, wherein the processing circuit implements a secondary path adaptive filter having a secondary path response that shapes the source audio and a combiner that removes the source audio from the error microphone signal to provide the error signal, and wherein the processing circuit injects intermittent bursts of noise from the noise source into the secondary path adaptive filter and the audio signal reproduced by the transducer ...

An adaptive noise canceling (ANC) circuit adaptively generates an anti-noise signal from a reference microphone signal that is injected into the speaker or other transducer output to cause cancellation of ambient audio sounds. An error microphone proximate the speaker provides an error signal. A secondary path estimating adaptive filter estimates the electro-acoustical path from the noise canceling circuit through the transducer so that source audio can be removed from the error signal. Tones in the source audio, such as remote ringtones, present in downlink audio during initiation of a telephone call, are detected by a tone detector using accumulated tone persistence and non-silence hangover counting, and adaptation of the secondary path estimating adaptive filter is halted to prevent adapting to the tones. Adaptation of the adaptive filters is then sequenced so any disruption of the secondary path adaptive filter response is removed before allowing the anti-noise generating filter to adapt. 1.

A personal audio device, such as a wireless telephone, generates an anti-noise signal from a microphone signal and injects the anti-noise signal into the speaker or other transducer output to cause cancellation of ambient audio sounds. The microphone measures the ambient environment, but also contains a component due to the transducer acoustic output.
