Patent number: 7151350Abstract: A non-contact detection system and method for detecting obstructions in relation to a powered door on a vehicle such that contact with the door may be prevented. The detection system includes an object detection sensor located on the powered door for sensing an object within an adjustable sensing zone. A door position sensor senses position of the door relative to at least one of an open and closed door position. A controller adjusts the sensing zone of the object detection sensor as a function of the sensed door position.Type: GrantFiled: February 11, 2004Date of Patent: December 19, 2006Assignee: Delphi Technologies, Inc.Inventors: Ronald Helmut Haag, Jeremy M Husic, John Pasiecznik, Jr.

Patent number: 6777958Abstract: A method for detecting a change in capacitance of a capacitive sensing element having a nominal capacitance value is disclosed. In an exemplary embodiment, the method includes coupling the sensing element to a first oscillator, the first oscillator generating a first frequency dependent upon the capacitance value of the sensing element. The first frequency is compared to a reference frequency generated by a second oscillator. The change in capacitance from the nominal capacitance value is detected if the first frequency differs from said reference frequency by a determined frequency value.Type: GrantFiled: May 10, 2002Date of Patent: August 17, 2004Assignees: Delphi Technologies, Inc., Hughes Aircraft CompanyInventors: Ronald Helmut Haag, John Pasiecznik, Jr.

Patent number: 6750624Abstract: A non-contact obstacle detection system utilizing ultra sensitive capacitive techniques. In an exemplary embodiment, the system includes a sensing element disposed in proximity to a moveable panel and a proximity detection circuit in communication with the sensing element. The proximity detection circuit generates a differential output signal reflective of whether a foreign object is in proximity to the sensing element. In addition, a central control module is in communication with the sensing element. The central control module determines whether the differential output signal is reflective of a foreign object in proximity to the sensing element. If the central control module determines that the differential output signal is reflective of a foreign object in proximity to the sensing element, and the moveable panel is moving toward a closed position, then the central control module generates a control output signal to stop the moveable panel from moving toward the closed position.Type: GrantFiled: May 10, 2002Date of Patent: June 15, 2004Assignee: Delphi Technologies, Inc.Inventors: Ronald Helmut Haag, Brian Deplae, Jeremy M. Husic, John Pasiecznik, Jr.

Patent number: 6723933Abstract: A flexible, capacitive strip for use in a non-contact obstacle detection system is disclosed. In an exemplary embodiment, the strip includes an elongated body for flexible mounting to a panel along a bottom surface of the elongated body. A first elongated planar conductor is contained within an upper section of the elongated body, and a longitudinal cavity is formed through a central portion of the elongated body, the longitudinal cavity being disposed between the planar conductor and the bottom surface. The first elongated planar conductor forms a first electrode of a sensing capacitor and the longitudinal cavity defines a portion of a dielectric material of the sensing capacitor.Type: GrantFiled: May 10, 2002Date of Patent: April 20, 2004Inventors: Ronald Helmut Haag, Brian Deplae, Jeremy M.

Patent number: 5600256Abstract: A flexible membrane (12) of an integrated circuit chip test probe is provided with raised contact features (14) on one side arranged in the pattern of contact pads of the chip to be tested. During manufacture, the membrane, in the area of its raised contact features, is specifically shaped by applying a vacuum to the outside of the membrane and casting a solid resilient elastomer (26) in place on the other side of the membrane to act as a shape retaining solid backup and to provide an anti-drape (226) shaped membrane (212) or to ensure planarity (326) of the ends of the membrane contact features (314). The vacuum may be used to pull the membrane and its contacts against a shape defining mandrel (60, 260, 360) while the elastomer is cast into place.Type: GrantFiled: February 13, 1995Date of Patent: February 4, 1997Assignee: Hughes ElectronicsInventors: Blake F.

Patent number: 4803644Abstract: A hardware system is disclosed for detecting alignment marks on a substrate in connection with electron beam lithography. The system is considerably faster than prior software approaches. A scanning signal derived from backscattered electrons as the beam scans the substrate is stored and updated in a set of shift registers as scanning proceeds. The signals in the scanning shift registers are compared with a predetermined reference signal, corresponding to the expected scanning signal when the beam traverses an edge of an alignment mark, stored in another set of shift registers. A correlation is obtained between the scanning and reference signals by multiplying the values of the corresponding cells in the scanning and reference registers, and accumulating and weighting the result. The locations of the maximum positive and negative correlations, and hence the locations of the opposed edges of the alignment mark, are obtained by means of a timing mechanism coordinated with the scanning.Type: GrantFiled: September 20, 1985Date of Patent: February 7, 1989Assignee: Hughes Aircraft CompanyInventors: James F.
