Patent number: 9312964Abstract: A digital version of both amplitude and phase of a received optical is developed by employing direct differential detection in conjunction with digital signal processing. The signal is split into three copies. An intensity profile is conventionally obtained using one of the copies. Phase information is obtained by supplying each remaining copy to a respective one of a pair of optical delay interferometers that have orthogonal phase offsets, followed by respective balanced intensity detectors. The output of each of the balanced intensity detectors, and the intensity profile, are each converted to respective digital representations. Signal processing is used to develop the phase information from the digital representations of the output of the balanced intensity detector outputs.Type: GrantFiled: September 22, 2006Date of Patent: April 12, 2016Assignee: Alcatel LucentInventors: Xiang Liu, Xing Wei

Patent number: 9177544Abstract: A system includes a controller for receiving first and second signals representative of a load on an engine, and generating based on the signals. Harmonic scaling elements generate a scaled version of a received engine harmonic signal. Each harmonic scaling element includes a harmonic specific mapping element for mapping the control parameter to a harmonic specific scaling factor. Some of the harmonic specific scaling factor values of the harmonic specific mapping element are mapped to control parameter values associated with a negative load on the engine, and some are mapped to control parameter values associated with a positive load on the engine. The control parameter values associated with the negative load are derived from the first signal, and control parameter values associated with the positive load are derived from the second signal. An adjustable gain element applies the harmonic specific scaling factor to the received engine harmonic signal.Type: GrantFiled: April 2, 2012Date of Patent: November 3, 2015Assignee: Bose CorporationInventor: Cristian M.

Patent number: 9177561Abstract: A system and method may be configured to reconstruct an audio signal from transformed audio information. The audio signal may be resynthesized based on individual harmonics and corresponding pitches determined from the transformed audio information. Noise may be subtracted from the transformed audio information by interpolating across peak points and across trough points of harmonic pitch paths through the transformed audio information, and subtracting values associated with the trough point interpolations from values associated with the peak point interpolations. Noise between harmonics of the sound may be suppressed in the transformed audio information by centering functions at individual harmonics in the transformed audio information, the functions serving to suppress noise between the harmonics.Type: GrantFiled: January 9, 2015Date of Patent: November 3, 2015Assignee: The Intellisis CorporationInventors: David C.
