  • Patent number: 9260930
    Abstract: A wellbore system suitable for conducting pressure testing of wellbore equipment. The system comprises a casing and a pressure testing valve incorporated within the casing. The pressure testing valve further comprises a sleeve positioned within a housing and transitional from a first to a second position, and from the second to a third position. When the sleeve is in the first and second positions, the sleeve blocks a route of fluid communication via one or more housing ports. When the sleeve is in the third position the sleeve does not block fluid communication. The pressure testing valve is configured such that the sleeve transitions from the first position to the second position when a force in the direction of the second position is applied to the sleeve. When in the second position, a reduction of the force in the direction of the second position to the sleeve causes the sleeve to transition to the third position.

  • Patent number: 9029714
    Abstract: An electromagnetically shielded enclosure that is portable and lightweight with a double perimeter entry seal. The electromagnetically shielded enclosure can be used for applications such as testing and security and can be scaled from a bench top unit to a large field deployed enclosure. The electromagnetically shielded enclosure has a novel entry seal that eliminates the electromagnetic leakage that is common around the entry areas of such enclosures. The entry seal of the electromagnetically shielded enclosure is made up of a door having a first perimeter closure material and a second perimeter closure material and an enclosure opening having a first perimeter closure and a second perimeter closure where the first perimeter closure material aligns with the first perimeter closure and the second perimeter closure material aligns with the second perimeter closure. This double perimeter entry seal provides for electromagnetic isolation within the electromagnetically shielded enclosure.

  • Patent number: 8939081
    Abstract: A weapon-locating ladar system estimates a backward trajectory of an airborne target by using flow field measurements to follow the wake turbulence trailing the airborne target from a position at which the target is detected backwards until the wake is no longer observable. The system may use the backward trajectory to estimate the point-of-origin of the target. The system may also use the flow field measurements along the backward trajectory to classify the target. Target classification may be used to refine the point-of-origin estimate, to influence counter-fire or to adapt the flow field measurements.

  • Patent number: 8804509
    Abstract: A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.
