Abstract: An anisotropic elastomeric conductor is fabricated by stacking a plurality of first and second sheets, where the first sheets include a plurality of parallel electrically conductive fibers (14) and the second sheets are composed of electrically insulating material. By introducing a curable elastomeric resin into the layered structure of sheets, and then curing the resin, a solid elastomeric block (30) having a plurality of parallel electrically conductive fibers (14) running its length is obtained. individual elastomeric conductors suitable for interfacing between electronic components (30) are obtained by slicing the block in a direction perpendicular to the conductors. The conductor slices (22) so obtained are particularly suitable for interfacing between electronic devices having planar arrays of electrical contact pads.

Abstract: An angle measuring device for the measurement of angles, comprising two rigid rodlike elements which are intended to be pressed upon two objects which subtend an angle to be measured, and an angle transducer of elastic material between the two rodlike elements. Upon said angle transducer, in longitudinal direction, at least one strain sensor is provided, the change of resistance of which - when the angle transducer is bent over the angle to be measured resulting in a change of length of said strain sensor - is a measure for the angle subtended by the two rodlike elements. An electronic measuring means is connected to the strain sensor. The rodlike elements each have at least one flattened pressing side and the angle transducer comprises a flat strip of a material which withstands any permanent deformation and which flat strip is fastened, parallel to the flattened pressing sides, between the rodlike elements. The thickness of the flat strip, along its whole length, is constant and the direction of bending is in a plane perpendicular to the flattened sides of the rodlike elements. The strain sensor is durably fastened on at least one broad side of the flat strip along its whole length, which strain sensor comprises a metal layer.

Abstract: A method and apparatus for perforating oil well casing in a well bore, with particular advantage in highly deviated well bores, uses a perforating gun assembly (15) run into the well bore (10) using the production tubing (12). A sliding sleeve (14) is connected in the tubing above the gun and a packer (13) is run in for setting above the sliding sleeve and gun. The assembly is run into the well bore until the gun extends into the highly deviated portion of the bore where the well casing is to be perforated. The packer is set into place, isolating that portion of the well bore below the packer from that portion above the packer, and the sliding sleeve is opened using a wireline or other means. The well bore below the packer is pressurized through the tubing to ensure that the packer is properly set. The pressure is then allowed to bleed off and the sliding sleeve is closed. The gun uses a differential pressure-actuated firing head which is actuated upon a predetermined differential pressure between the production tubing bore and the annulus between the tubing and the casing. Thus, a well casing can be perforated using relatively low values of actuating pressure, which provides greater control over perforating conditions such as underbalance.

Abstract: A system interconnects electronic modules with one another, to a power supply and to signal lines through a printed circuit board. The modules are elec­trically connected to traces on the printed circuit board using blind mateable connectors. EMI shielding plates are mounted to the circuit board at the I/O con­nectors for the external cables. Guide elements, such as pin and socket guides and printed circuit board edge guides, are mounted to the circuit board to guide the blind mateable connectors. The system eliminates the numerous cables which would otherwise be required. The printed circuit board is mounted within the system hous­ing and acts as an air duct barrier to aid proper air circulation. The circuit board also acts as a structured element helping to stabilize the housing and various module supports and serves as a mounting structure for various elements, such as cooling fans.

Abstract: A battery powered (40) electronic locking apparatus comprises a locking member (2) movable between a locking position and an unlocking position, a first electromechanical means (110) coupled to the locking member to drive the locking member from one of the positions to the other position upon activation of the first electromechanical means and a second electromechanical means (111) coupled to the locking member to drive the locking member from the one position to the other position upon activation of the second electromechanical means. A control means (3) activates the first electromechanical means (110) without the second electromechanical means (111) to attempt to drive the locking member from the one position to the other position to conserve power, and subsequently activates the first (110) and second (111) electromechanical means together to attempt to drive the locking mechanism (2) to the other position. This provides movement of the locking member (2) when the battery voltage is low or the locking member is bound. In addition, if one attempt by one (110) or both (110, 111) electromechanical means is unsuccessful, the control means (3) automatically activates (254, 256, 258) one or both of the electromechanical means a second time. This is effective in the event that the failure was due to torque applied by a user to a door handle which bound the locking member.
