Filed:

Mar 5, 2002

Appl. No.:

10/091200

Inventors:

Matthew Sweetland - Somerville MA
Merlin D. Hansen - Missouri City TX

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 4400

US Classification:

7315251, 7315248, 7315246, 7315227, 16625001, 1662542

Abstract:

A hydraulic strain sensor for use with a downhole tool includes a housing having two chambers with a pressure differential between the two chambers. A mandrel is disposed in the housing. The mandrel is adapted to be coupled to the tool such that the weight of the tool is supported by the pressure differential between the two chambers. A pressure-responsive sensor in communication with the one of the chambers is provided to sense pressure changes in the chamber as the tool is accelerated or decelerated and to generate signals representative of the pressure changes.

Assignee:

Tribotek, Inc. - Burlington MA

International Classification:

H01R012/00

US Classification:

439 67

Abstract:

A multiple-contact woven connector including a weave arranged to provide a plurality of tensioned fibers and a conductor woven with the plurality of tensioned fibers so as to form a plurality of peaks and valleys along a length of the conductor. The conductor has a plurality of contact points positioned along the length of the conductor, such that when the conductor engages a conductor of a mating connector element, at least some of the plurality of contact points provide an electrical connection between the conductor of the multiple-contact woven connector and the conductor of the mating connector element. The tensioned fibers of the weave provide a predetermined contact force between the at least some of the plurality of contact points of the conductor of the multiple-contact woven connector and the conductor of the mating connector element.

Matthew Sweetland - Medford MA, US

Assignee:

Tribotek, Inc. - Burlington MA

International Classification:

H01R012/00

US Classification:

439 67

Abstract:

The present disclosure is directed to electrical cable connector assemblies that have a woven connector element and a cable subassembly. The woven connector element utilizes loading fibers and conductors. Each conductor has at least one contact point. The conductors are woven with the loading fibers so that when the loading fibers are placed in tension, a normal contact force is exerted at each of the contact points of the conductors. The conductors of the woven connector element extend into the cable subassembly. Thus, the conductors of the cable connector assembly are integral to both the woven connector element and the cable subassembly. In certain exemplary embodiments, a cable connector assembly further includes a mating conductor that has a contact mating surface, where electrical connections can be established between the contact points of the conductors and the contact mating surface of the mating conductor. In certain embodiments, the cable connector assemblies of the present disclosure can be utilized as cable-to-cable connector assemblies or cable-to-board connector assemblies. Moreover, in certain embodiments, the cable connector assemblies of the present disclosure can be utilized as data cable connector assemblies or power cable connector assemblies.

Assignee:

Tribotek, Inc. - Burlington MA

International Classification:

H01R012/00

US Classification:

439 67, 439329, 439493

Abstract:

Multiple-contact woven power connectors are provided that have at least a first set of loading fibers and at least a first set of conductors. When woven onto a set of loading fibers, the conductors define a space. The loading fibers are capable of delivering contact forces at the contact points of the conductors. The conductors can include a power circuit or a return circuit. The power connectors may also include tensioning springs that are capable of generating tensile loads within the loading fibers. The power connectors may further include mating conductors that can be coupled to the power/return circuits. When disposed within the first and second spaces, respectively, electrical connections between the conductors and the mating conductors can be established.

Matthew Sweetland - Bedford MA, US

Assignee:

Tribotek, Inc. - Burlington MA

International Classification:

H01R 12/00

US Classification:

439296, 439930, 439 67, 29622, 29825, 29826, 29829, 29846, 29850

Abstract:

An electrical connector that has an array of conductors each having a contact point to make contact with a mating conductive surface. Upon engaging the contact points in a sliding manner with the mating surface, the conductors are displaced, which, in turn, tensions a loading fiber within the connector. Tensioning of the loading fiber provides a contact force between the contact points and the mating surface.

Abstract:

A bearing adapted to support and allow controlled relative movement with an opposed bearing surface. The bearing is constructed to have a long life by incorporating a surface that addresses many causes of friction and wear. The bearing includes a plurality of support members extending from a base. Together, the plurality of support members can support a load applied to the base through an opposed bearing surface. Additionally, the plurality of support members allow sliding modes of motion between the opposed bearings. These support members can move independently to accommodate irregularities located between the support member and the opposed bearing, such that plowing is reduced and wear to the bearings is minimized. The support members may also be configured to allow certain non-sliding modes of motion between opposed bearing surfaces while resisting other non-sliding modes of motion.
