Abstract: A method is described including receiving multiple requests for a multicast service, generating parameters associated with binding paths to a multicast tree to provide the requested multicast service and binding the paths to the multicast tree.  Also described is a method including receiving a request for multicast service with a multicast tree identification, binding the multicast tree identification to paths satisfying a quality of service level for the multicast tree identification and transmitting a first message to a multi-hop relay base station. A method is described including receiving requests to delete multicast service from client devices served by multiple paths, generating parameters associated with unbinding paths from a multicast tree to delete the multicast service and unbinding the paths from the multicast tree. Also described is a method for unbinding of paths from the perspective of the relay station.

Abstract: A valve assembly includes a solenoid can having an internal coil. A valve body connected to the solenoid can includes an inlet port and a first valve seat. An axially adjustable retainer threadably connected to the valve body includes an end portion defining a second valve seat. A homogenous valve member/armature slidably disposed in the valve body moves in the presence of a coil generated magnetic flux between valve closed and valve open positions. A valve member/armature first surface area is in fluid communication with a pressurized fluid through the inlet port. A valve member/armature second surface area is in fluid communication with the pressurized fluid in the valve closed position.  The first surface area is equal to the second surface area and the pressurized fluid acts equally on the first and second surface areas defining a pressure balanced condition in the valve closed position.

Abstract: A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition.    The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.

Abstract: A low-profile mount for a flat panel electronic display that is selectively shiftable between a wall-confronting position wherein the back of the flat panel electronic display is disposed parallel and proximate to the wall surface and a tilt position wherein the top of the display is tilted away from the wall surface. The mount is configured so that points spaced apart forwardly from display receiving surfaces of the mount are shifted along a substantially horizontal axis as the mount is shifted between the wall confronting position and the tilt position. Advantageously, the display can be attached to the mount so that the points are horizontally registered with a center of gravity of the display such that the display is self-balancing at any point along the travel between the wall confronting position and the tilt position.

Abstract: Systems and methods of processing video data are provided.    Video data having a series of video frames is received and processed.  One or more instances of a candidate feature are detected in the video frames. The previously decoded video frames are processed to identify potential matches of the candidate feature. When a substantial amount of portions of previously decoded video frames include instances of the candidate feature, the instances of the candidate feature are aggregated into a set. The candidate feature set is used to create a feature-based model. The feature-based model includes a model of deformation variation and a model of appearance variation of instances of the candidate feature. The feature-based model compression efficiency is compared with the conventional video compression efficiency.
