| 20110214970 | Resistance Device For High Voltage Switch Assembly - A resistance device for an electrical switch assembly includes a housing having a base and first and second support brackets extending outwardly therefrom. The base receives first and second conductive blades of the electrical switch assembly. A cam member is movably connected to the first and second supporting brackets. First and second spring members are connected between the base and the cam member and bias the cam member away from the base. The amount of force required to open and close the switch assembly is increased by having to overcome the resistance force imparted by the first and second spring members on the cam member during rotation of the conductive blades. | 09-08-2011 |

| 20100218353 | RESONATOR SENSOR ASSEMBLY - An improved method and assembly, wherein the method generally includes the steps of providing a coated or uncoated sensor element having an exposed sensing surface; attaching the sensor element to a platform so that the exposed sensing surface is spaced from the platform; and optionally applying a protective layer over the platform while maintaining the sensing surface as exposed. The assembly includes a resonator having a free portion with a sensing surface is incorporated onto a platform, components of the sensor are physically shielded from harsh operating conditions, the requisite space is maintained between the free portion of the resonator and the platform, and the sensing surface of the resonator remains exposed for sensing. | 09-02-2010 |

| 20110067854 | DOWNHOLE SEQUENTIALLY-FIRING CASING PERFORATING GUN WITH ELECTRONICALLY-ACTUATED WIRELINE RELEASE MECHANISM, AND ACTUATION CIRCUIT THEREFOR - A downhole release tool for use in conjunction with multiple select-fire perforating guns and a method for electronically actuating the release tool using either positive or negative control voltage. In a preferred embodiment, the release tool employs operating circuitry that allows actuation of the release tool by either a positive or a negative voltage at an absolute magnitude greater than the absolute magnitude of positive or negative voltages used to arm or fire the perforating guns. | 03-24-2011 |
