Patent number: 6539299Abstract: A method and control apparatus for an internal combustion engine that allows an operator to calibrate engine performance relative to an engine operating characteristic. The control apparatus comprises a base engine control map that correlates values of the characteristic with values of a base engine control, a trim control map that correlates the values of the characteristic with values of a trim control, an engine control unit that obtains from the base engine control and trim control maps the respective base engine control and trim control values that are based on the characteristic value, and a panel that is operatively coupled with the engine control unit and includes a first switch regulating a trim signal supplied to the engine control unit. The trim control map is separated from the base control map. The engine control unit calculates an engine operating control value based on the obtained values.Type: GrantFiled: February 16, 2001Date of Patent: March 25, 2003Assignee: Optimum Power TechnologyInventors: Glen F. Chatfield, Roy D. Houston, Philip D. McDowell

Patent number: 5779454Abstract: Disclosed herein is a fuel pump comprising a housing including therein a high pressure fuel chamber, a fuel outlet valve communicating with the high pressure fuel chamber and being operable to prevent fuel inflow and to permit fuel outflow when the fuel pressure is above a predetermined level, a fuel inlet valve communicating with the high pressure chamber and being operable to prevent fuel outflow and to permit fuel inflow, and a bearing bore extending from the high pressure chamber, a rod slideably and sealingly supported in the bearing bore for movement relative to a retracted position, and structure located in the housing for displacing the rod from the retracted position and in the direction toward the high pressure fuel chamber through an initial stroke length without encountering substantial resistance and thereafter displacing the rod through a subsequent stroke length which is effective to highly pressurize the fuel in the high pressure fuel chamber.Type: GrantFiled: July 25, 1995Date of Patent: July 14, 1998Assignee: FICHT GmbH & Co. KGInventors: Gregory J. Binversie, Wolfgang Heimberg, Theodore J. Holterman, Christopher R. Irgens, Francis A. McGinnity, Philip D. McDowell, Richard T. Tunkieicz, Lee A. Woodward, Wolfram Hellmich

Patent number: 5153589Abstract: A data processing terminal is provided with a keyboard which can be removed to provide access to the interior of the terminal for maintenance and repair of electrical components contained therein. Removal of the keyboard causes the operating circuit for the terminal to be interrupted, thereby eliminating danger of shock to someone working in the interior of the terminal. Assembly of the keyboard to the remainder of the terminal is accomplished largely by means of molded engaging and latching elements, thereby minimizing the effort required for assembly and disassembly.Type: GrantFiled: February 12, 1990Date of Patent: October 6, 1992Assignee: NCR CorporationInventors: George Heys, Jr., Andrew E. Yandora, Philip D. McDowell

Patent number: 4841412Abstract: An electronic terminal device is fabricated so as to be quickly and easily assembled and disassembled by use of housing parts and internal parts having snap-type fasteners. Separate fasteners such as screws are not needed. Special tools are not required for assembly and disassembly of the device. Performance of repair and maintenance functions by purchasers of the equipment is thus facilitated.Type: GrantFiled: June 29, 1988Date of Patent: June 20, 1989Assignee: NCR CorporationInventors: George Heys, Jr., Andrew E. Yandora, Philip D. McDowell

Patent number: 4816619Abstract: Passive strain relief apparatus provides relief of strain on cable connections to electrical components within an electrical device such as a point of sale terminal, which strain is caused by tension on cables extending from said device. The strain relief apparatus includes a flexible strain relief element which is located within said device and is positioned adjacent to an opening in said device through which the cables extend. The cables are pinched by recesses in the strain relief element in which they are positioned. Tension on the cables causes said strain relief element to flex, thereby relieving the tension.Type: GrantFiled: June 29, 1988Date of Patent: March 28, 1989Assignee: NCR CorporationInventors: George Heys, Jr., Andrew E. Yandora, Philip D. McDowell
