Patent number: 11184729Abstract: Disclosed herein are related to a system and a method for synchronizing signal processing on audio channels. In one aspect, a system includes processors, each including an audio data input configured to receive audio data from multiple audio sources. In one aspect, each processor includes audio channels coupled to the audio data input, where each audio channel includes a corresponding processing chain configured to convert a sample rate of audio data from a corresponding audio source. Each processor may include a synchronization pulse generator configured to generate a corresponding synchronization pulse for each processing chain in response to a trigger pulse. The synchronization pulse generator may include a counter configured to generate an output having a phase based on a programmable initial condition of the counter, where the synchronization pulse for each processing chain is based on the counter output and a phase register value of the corresponding processing chain.Type: GrantFiled: May 29, 2020Date of Patent: November 23, 2021Assignee: Knowles Electronics, LLCInventors: Christopher Konrad Wolf, Erick Alvarado

Patent number: 10979824Abstract: A method in a transducer assembly having an external-device interface coupled to a communication protocol interface of the transducer assembly. The transducer assembly is configured to convert an input signal having one physical form to an output signal having a different physical form. At least two electrical signals are received on corresponding contacts of the external-device interface of the transducer assembly. A characteristic of at least one of the electrical signals is determined by evaluating a logic transition of the signal. A unique identity assigned to the transducer assembly is determined based on the characteristic.Type: GrantFiled: October 25, 2017Date of Patent: April 13, 2021Assignee: Knowles Electronics, LLCInventors: Christopher Konrad Wolf, Niel D.

Patent number: 6304021Abstract: A method and apparatus are proposed for operating a microacoustic sensor arrangement, for example, to determine the physical characteristics of a measurement medium. Acoustic surface waves with predetermined wave modes are generated and detected by electroacoustic transducers (6) and a measurement for the physical characteristics of the measurement medium is determined from their propagation behavior along a propagation path. In addition, a sagittally polarized surface wave is generated in the area of the surface of the substrate (5; 22) on which the measurement medium is located.Type: GrantFiled: June 8, 2000Date of Patent: October 16, 2001Assignee: Robert Bosch GmbHInventors: Konrad Wolf, Hans Hecht, Falk Herrmann

Patent number: 4358762Abstract: The variable inductor and the comparison inductor of a semi-differential variable inductance both have a pair of coils magnetically coupled together. The output current of an amplitude-controlled oscillator flows through the series combination of one coil of each pair and the other coil of the comparison inductor is used to supply a signal which is rectified in order to regulate the amplitude of the oscillator. The remaining coil, the other coil of the variable inductor, is rectified to provide an output signal representative of the ratio of the variable inductance to the comparison inductance and also representative of the displacement of the short-circuiting ring of the variable inductance, which is mechanically linked to the control rod of a fuel injector of a diesel engine as required for a system controlling the fuel injector. The oscillator and the rectifiers can conveniently use operational amplifiers of the same type designation.Type: GrantFiled: September 25, 1980Date of Patent: November 9, 1982Assignee: Robert Bosch GmbHInventors: Konrad Wolf, Erich Zabler
