Publication number: 20180328954Abstract: A sensor suitable for sensing the relative movement between at least part of the sensor and one or more target objects. The sensor including at least one polarised or at least partially polarised dielectric material and at least one electrode. The interaction of the one or more target objects with the static electric field of the dielectric material produces a signal or voltage change in the electrode.Type: ApplicationFiled: August 4, 2016Publication date: November 15, 2018Inventor: Calvin Cox

Patent number: 10074940Abstract: A conductive EMI shielding assembly for shielding the connection between a multi-wire cable and a corresponding circuit board connector is disclosed, and includes a housing portion for surrounding the circuit board connector and a coupling portion for mating with the housing portion and the cable. The housing portion has a base with a rectangular configuration and a collar portion that mates with a corresponding collar portion of the coupling portion. The coupling portion has an opposing end that slips over the end of the cable and attaches to the cable. The housing collar portion and coupling mating portion include associated tabs and openings arranged around them in a circular pattern at preselected angular intervals. The tabs and openings permit the coupling portion to be oriented with respect to the housing portion in a number of different patterns.Type: GrantFiled: May 2, 2017Date of Patent: September 11, 2018Assignee: Molex, LLCInventor: Calvin Cox

Patent number: 9562923Abstract: A speed sensor for use in measuring the speed of rotation of a rotationally salient rotating member. The speed sensor comprises an electrode and a sensor circuit. The sensor circuit comprises a constant voltage source for supplying a voltage to the electrode to generate an electric field in a dielectric medium. A current detector detects current flow between the constant voltage source and the electrode due to perturbation of the electric field by passage of at least one salient feature of the rotating member through the electric field as the rotating member rotates. The current detector outputs a first signal modulated at a frequency corresponding to the frequency of perturbation of the electric field. The first signal is amplified to produce an amplified signal modulated at a frequency corresponding to the frequency of perturbation of the electric field.Type: GrantFiled: December 17, 2012Date of Patent: February 7, 2017Assignee: Cummins Turbo Technologies LimitedInventors: Calvin Cox, Thomas W.
