Patent number: 9126502Abstract: A dual-electrode occupant detection system configured to determine an occupant presence on a seat assembly. The system includes two electrodes that each generates an electric field in response to an applied excitation signal. The two electrode signals arising therefrom can be measured individually and/or combined to detect more reliably an occupant. Such a configuration advantageously avoids the added expense and complication of an electrode arrangement that relies on an underlying shield layer to reduce electrode signal degradation caused by a seat heater element.Type: GrantFiled: August 14, 2012Date of Patent: September 8, 2015Assignee: Delphi Technologies, Inc.Inventors: Kevin D.

Publication number: 20120286813Abstract: A system, controller, and method for detecting moisture on a windshield that uses an isolated electrode coupled to a windshield. The isolated electrode is configured to exhibit an electrical impedance indicative of moisture present on a surface the windshield. The controller is configured to determine an electrode impedance value corresponding to the electrical impedance exhibited by the isolated electrode for detecting moisture on the windshield. By using an isolated electrode, the system is simpler and less expensive than other systems that have at least one electrode providing a return path for another electrode. Also, a way to use the isolated electrode for both detecting moisture on the windshield, and heating the windshield is described.Type: ApplicationFiled: May 12, 2011Publication date: November 15, 2012Inventors: MORGAN D.

Patent number: 8249798Abstract: A vehicle pre-impact sensing system is provided that includes an array of energy signal transmitters mounted on a vehicle for transmitting signals within multiple transmit zones spaced from the vehicle and an array of receiver elements mounted on the vehicle for receiving signals reflected from an object located in one or more multiple receive zones indicative of the object being in certain one or more zones. A processor processes the received reflected signals and determines range, location, speed and direction of the object, determines whether the object is expected to impact the vehicle as a function of the determined range, location, speed and direction of the object, and generates an output signal indicative of a pre-impact event. The system may detect one or more features of a target object, such as a front end of a vehicle. Additionally, the system may modulate the transmit beams. Further, the system may perform a terrain normalization to remove stationary items.Type: GrantFiled: May 20, 2009Date of Patent: August 21, 2012Assignee: Delphi Technologies, Inc.Inventors: Kevin J.
