Patents by Inventor Aleksey Khenkin

Aleksey Khenkin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11190890
    Abstract: An acoustic testing apparatus may include connections for multiple devices under test (DUTs) to support simultaneous testing of two or more miniature electroacoustic devices. The acoustic testing apparatus may allow the testing of multiple DUTs with a ratio of less than one reference microphone per DUT. Thus, the speed of testing DUTs may be increased without adding significant cost through additional reference microphones. For example, a single reference microphone may be used to test two or four DUTs coupled together through an acoustic test cavity.

  • Publication number: 20210328535
    Abstract: A method for minimizing undesired movement of a moving mass of an electromagnetic load may include detecting undesired movement of the moving mass based on real-time measurements of one or more parameters associated with the electromagnetic load and, responsive to detecting undesired movement of the moving mass, affecting a signal applied to the moving mass to reduce the undesired movement.

  • Publication number: 20210325967
    Abstract: A method may include measuring an electrical parameter of an electromagnetic load having a moving mass during the absence of a driving signal actively driving the electromagnetic load, measuring a mechanical parameter of mechanical motion of a host device comprising the electromagnetic load, correlating a relationship between the mechanical parameter and the electrical parameter, and calibrating the electromagnetic load across a plurality of mechanical motion conditions based on the relationship.

  • Patent number: 10080084
    Abstract: In accordance with embodiments of the present disclosure, a system may include a digital correcting network for correcting for an intrinsic highpass filter of a microelectromechanical systems (MEMS) microphone such that a combined phase and magnitude response of a cascade of the intrinsic highpass filter and the digital correcting network substantially approximates the response of a target highpass filter.

  • Patent number: 9681242
    Abstract: A MEMS microphone system suited for harsh environments. The system uses an integrated circuit package. A first, solid metal lid covers one face of a ceramic package base that includes a cavity, forming an acoustic chamber. The base includes an aperture through the opposing face of the base for receiving audio signals into the chamber. A MEMS microphone is attached within the chamber about the aperture. A filter covers the aperture opening in the opposing face of the base to prevent contaminants from entering the acoustic chamber. A second metal lid encloses the opposing face of the base and may attach the filter to this face of the base. The lids are electrically connected with vias forming a radio frequency interference shield. The ceramic base material is thermally matched to the silicon microphone material to allow operation over an extended temperature range.

  • Publication number: 20060078134
    Abstract: An in-line microphone filter may include a housing and a filter circuit housed in the housing. A first connector at one end of the housing is connected to an input of the filter circuit and a second connector at another end of the housing is connected to an output of the filter circuit. The filter circuit may filter the microphone audio signal by changing sonic characteristics of the audio signal in a predetermined manner dependent upon a specific type of acoustic source or instrument.
