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.

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.

Patent number: 4891640Abstract: A high temperature and high pressure fiber optic feedthrough is set forth to enable communication to the interior of a pressure housing making up a downhole logging tool. An optical fiber is stripped of protective wraps and coverings other than a fluorocarbon coating. It is inserted into a feedthrough fitting formed of an elongate body that feeds to the pressure housing. There is an axial bore which has an internal cavity at the upper end. This cavity receives a conic section of a resilient body which is deformable. Through the use of a specially designed syringe, the optical fiber is passed through this cavity and is positioned on the interior bore of the body. The resilient material is able to expand on application of pressure. The cavity is closed by means of a retainer nut and wear washer. When the nut is tightened, the resilient material extrudes around and along the optical fiber and seals against it to perfect a high pressure, high temperature seal against the intrusion of well fluids.Type: GrantFiled: November 3, 1988Date of Patent: January 2, 1990Assignee: Halliburton Logging Services, Inc.Inventor: Matthew Ip

Patent number: 4874327Abstract: A universal cable head is set forth which incorporates a stress relieving stinger on the end of a logging cable. The cable connects with wedge shaped members which grip the end of a cable within a housing. Electrical conductors, seven in number, extend from the end of the cable into the housing and are exposed in an internal cavity. In the cavity, they connect with a set of boots at the back end connecting with feedthrus by bayonet connection, the feedthrus being supported on a transverse bulkhead, and the feedthrus all extend through the bulkhead to locate male plugs within a circular housing. A rotatable threaded sleeve is on the exterior for connection with a mating female member. All of this structure connects universally to mating female connectors on downhole logging tools to provide the requisite number of conductors for downhole logging operations.Type: GrantFiled: November 7, 1988Date of Patent: October 17, 1989Assignee: Halliburton Logging Services, Inc.Inventor: Matthew Ip
