Patent number: 11988528Abstract: A position sensor is provided. The position sensor includes a target and a segment sensor element. The segment sensor element defines a circumferential direction and a radial direction. The segment sensor element includes a transmit coil. The segment sensor element includes a plurality of receive coils positioned within a space defined by the transmit coil. The plurality of receive coils are offset relative to one another. The shape of each of the plurality of receive coils corresponds to a periodic waveform having a radial width that varies along the circumferential direction. Furthermore, the shape of at least one receive coil of the plurality of receive coils is distorted along at least one of the radial direction or the circumferential direction.Type: GrantFiled: March 17, 2023Date of Patent: May 21, 2024Assignee: Kyocera AVX Components (Werne) GmbHInventors: Timothy Biggs, David Witts

Publication number: 20240011800Abstract: Rotary position sensors are provided. In one example implementation, a rotary position sensor can include a first member and a second member, one of the first and second members having a transmit aerial and a receive aerial and the other of the first and second members having an intermediate coupling element. The receive aerial has at least one receive conductive winding arranged to form a first set of current loops and a second set of current loops. The intermediate coupling element comprises a conductive material arranged in a pattern. The pattern of the intermediate coupling element and the layout of the first and second set of current loops are mutually arranged such that any electromotive force induced in the first set of current loops by a background magnetic field is substantially balanced by an electromotive force induced in the second set of current loops by the background magnetic field.Type: ApplicationFiled: July 10, 2023Publication date: January 11, 2024Inventors: David Witts, Timothy Biggs, Paul Smith, Peter Constantinou

Patent number: 11703359Abstract: An inductive position sensor may be configured to detect relative position between a first member and a second member. The inductive position sensor may include an inductive sensor element configured to be coupled to the first member and a screening layer formed over a screened portion of a member surface of the second member such that an exposed portion of the member surface is free of the screening layer. The screening layer may be configured to reduce an effect on induced signals in the inductive sensor element caused by the screened portion of the second member.Type: GrantFiled: May 7, 2020Date of Patent: July 18, 2023Assignee: Kyocera AVX Components (Werne) GmbHInventors: Paul Smith, Robert Wood, John Simm, Timothy Biggs

Publication number: 20210381853Abstract: Position sensing apparatus is provided. In one example implementation, the position sensing apparatus comprises a first member having an excitation conductive winding and a detection conductive winding formed thereon, and a second member having a resonant circuit formed thereon. An integrated circuit comprising excitation signal generation and detection signal processing circuitry is arranged to generate an alternating excitation signal at a resonant frequency of the resonant circuit and to process an alternating detection signal induced in the detection conductive winding as a result of a magnetic field generated by the alternating excitation signal flowing through the detection conductive winding, and the excitation conductive winding and the detection conductive winding are arranged so that the detection signal varies in dependence on the relative position of the first and second member.Type: ApplicationFiled: October 16, 2018Publication date: December 9, 2021Inventors: David Witts, Peter Constantinou, Paul Smith, Timothy Biggs, Andrew Parker
