Patent number: 7274079Abstract: An accelerometer (305) for measuring seismic data. The accelerometer (305) includes an integrated vent hole for use during a vacuum sealing process and a balanced metal pattern for reducing cap wafer bowing. The accelerometer (305) also includes a top cap press frame recess (405) and a bottom cap press frame recess (420) for isolating bonding pressures to specified regions of the accelerometer (305). The accelerometer (305) is vacuum-sealed and includes a balanced metal pattern (730) to prevent degradation of the performance of the accelerometer (305). A dicing process is performed on the accelerometer (305) to isolate the electrical leads of the accelerometer (305). The accelerometer (305) further includes overshock protection bumpers (720) and patterned metal electrodes to reduce stiction during the operation of the accelerometer (305).Type: GrantFiled: August 22, 2005Date of Patent: September 25, 2007Assignee: Input/Output, Inc.Inventors: Arjun Selvakumar, Howard D. Goldberg, Duli Yu, Matthew Ip, Martin A. Schmidt, James L. Marsh, Bing-Fai Fung, Philip Simon

Patent number: 7152473Abstract: A sensor apparatus (104) includes a plural different spatial direction axis of sensitivity positioned sensor package containing sensor module (305) supported by a planar surface (345) within a cavity (340) of a housing (205) coupled to a first end cap (210) by a PC-board connection (355). Housing (205) is further coupled to first end cap (210) by a first coupling member (315) and a second coupling member (320) and is also coupled to an opposite second end cap (215) by a third coupling member (320) and a fourth coupling member (325). Interface sealing members (330a, 330b, 330c, 330d) seal between housing (205) and first end cap (210). Interface sealing members (335a, 335b, 335c, 335d) seal between housing (205) and second end cap (215).Type: GrantFiled: March 17, 2000Date of Patent: December 26, 2006Assignee: Input/Output, Inc.Inventors: Larry Rushefsky, Axel Sigmar, Howard D. Goldberg, W. Marc Stalnaker, Ray Rinne, Demetrios Balderes, Guido Lemke, Matthew Ip, Lawrence P. Behn, Klaus Domagalski, Lianzhong Yu, Arjun Selvakumar, Duli Yu, James L.

Patent number: 7055148Abstract: A system and a method that uses a software application operable under a current firmware/operating system configuration to install a new firmware version without “compromising” the operating system are presented. The software application may configure a computer system to install a plurality of software fixes configured to enhance functionality under a new firmware/operating system environment after the firmware has been successfully upgraded. Such functionality enhancements may be associated with external peripherals, as well as, input/output circuit cards, processors, and the like. In addition, the software application may configure the computing device to “boot” under the new firmware/operating system environment upon subsequent system initializations. Furthermore, the software application permits the distribution of firmware upgrades via a network.Type: GrantFiled: December 7, 2000Date of Patent: May 30, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: James L Marsh, R Scott Holbrook, Eugene L Jung
