  • Patent number: 7838833
    Abstract: A method of imaging using an electron beam. An incident electron beam is focused onto the specimen surface, a scattered electron beam is extracted from the specimen surface, and a plurality of dark field signals are detected using a detection system. An interpolated dark field signal is generated using the plurality of dark field signals. In addition, a bright field signal may be detected using the detection system, and a final interpolated signal may be generated using the interpolated dark field signal and the bright field signal. User input may be received which determines a degree of interpolation between two adjacent dark field signals so as to generate the interpolated dark field signal and which determines an amount of interpolation between the interpolated dark field signal and the bright field signal so as to generate a final interpolated signal. Other embodiments, aspects and features are also disclosed.

  • Patent number: 7612348
    Abstract: A voltage-isolating passageway for providing high voltage isolation between a component maintained at high DC voltage and a component maintained at a substantially lower voltage is described. The voltage-isolating passageway incorporates a transverse magnetic field across its passageway, which reduces the potential energy of charged particles (e.g., electrons) passing through the passageway. The voltage-isolating passageway includes a passageway and at least two magnets. The passageway has two openings and the two magnets are positioned along opposite and exterior surfaces of the passageway wherein the first and second magnets impose a magnetic field in a transverse direction with respect to a lengthwise axis of the passageway. In one embodiment, each of the passageways have small diameters and transfer gases at small flow rates.

  • Patent number: 7451816
    Abstract: A well packing system and method for operating a well packing system wherein an isolation string assembly has a lower circulation valve with lateral flow ports that are operated to an open position without the use of shifters on a wash pipe. The isolation string assembly is incorporated into a well packing assembly within a wellbore and includes an upper sleeve tool that provides selective production of fluids through the frac pack assembly. In addition, the isolation string includes a lower circulation valve having a sliding sleeve that is shiftable from an open position to a closed position upon receipt of a suitable pressure differential. This configuration is particularly valuable for permitting monitoring of pressure or other conditions in the annulus of the wellbore portion being packed during packing operations. Further, the lower circulation valve tool can be used to selectively allow fluid returns during the packing operation.

  • Patent number: 6652557
    Abstract: A surgical capsule of the present invention is positioned in an artery or vein by threading a catheter containing the capsule from a proximal incision in the blood vessel to a location within the blood vessel adjacent to a lesion. The catheter comprises an outer holding sheath, an intermediate deployment sheath, and an inner guide wire, all of which are reciprocable with respect to each other. The capsule includes (1) a control sub-assembly that includes a hub and a plurality of outwardly biased leaf springs, and (2) a filter sub-assembly that includes a porous dome that is capable of permitting fluid flow, but retaining particles. Domes of different porosity may be affixed to the leaf springs. The position of the capsule is controlled by the guide wire. The present invention allows the interchangeability of mesh caps of different diameters and mesh sizes. By using the same capsule and the same deployment method, tines or hooks on the shrouds hold the elasticized rim on the mesh.

  • Patent number: 5495723
    Abstract: An improvement for converting an air conditioner or heat pump system into a water supply heater, including a water cooled condenser having a refrigerant throughflow passageway and a water throughflow conduit for bringing a water supply pumped therethrough into heat exchange relationship with the refrigerant. A three-way valve connects the compressor to the water-cooled condenser or to an exterior heat exchanger in the air conditioner, or a reversing valve in the heat pump. Control system including a water pressure switch for actuating the three-way valve, a refrigerant pressure activated water regulator valve mounted on the inflow side of the water throughflow conduit, and a thermostat, route refrigerant via the three-way valve to the water cooled condenser only when a water supply is desired to be heated, thereby preventing the build-up of scale in the condenser water conduits. The control system also switches off the fan of the exterior heat exchanger when the water-cooled condenser is in use.

  • Patent number: 4327591
    Abstract: A magnetically mountable device for sensing deformation from loadings on machine members. The device includes a strain sensing transducer, brackets between which the transducer is supported, and magnetic bracket mounts which permit the transducer to be easily mounted on the machine member by virtue of magnetic attraction forces between the mounts and the force carrying member and yet be readily repositionable on the member so as to facilitate location of points of maximum stress concentrations during a working cycle of the machine.
