Abstract: In one example, a method includes running a downhole system into a downhole environment that comprises a wellbore, and the downhole system is configured such that a reusable plug of the downhole system is positioned uphole of a perforation gun of the downhole system, then, with the perforation gun, perforating a casing at a stage of the wellbore, and the perforating is performed using a projectile, and the perforating is performed by firing the projectile from a chamber of the perforation gun.

Abstract: A dispenser includes a body that defines a chamber and a barrel that communicate with each other, and a penetrator assembly configured to be received in the chamber. The penetrator assembly includes a penetrator, a propellant operably positioned with respect to the penetrator, a primer in operable communication with the propellant, and an electrical conductor configured and arranged to carry electrical power to the primer. The dispenser may be positioned in a downhole location such as a wellbore, and the penetrator assembly may be fired so that the penetrator perforates a casing in the wellbore.

Abstract: A slab handling system provides an accessory that can be configured to secure vacuum grippers to a beam. The accessory includes a body having a passageway therethrough for receiving the beam. The body further including slots on either side of the passageway that are configured to receive connectors of a vacuum gripper. In one embodiment the accessory can also be configured as a height-adjusting device. In one embodiment the accessory can also be configured as a traction device. The height-adjusting device and the traction device may be used in conjunction with the accessory and vacuum grippers to facilitate handling of one or more slabs.

Abstract: An attachment system principally use on garment (10, 30) provides a number of aligned loops (15) on the garment and a number of aligned loops (24) on a load such as an equipment pack (17). The load also includes an elongate securing member that extends from the load with a flexible proximal portion (26) and a stiffened distal portion (27). The stiffened distal portion (27) can be very readily threaded through successive ensemble loops (15) and load loops (24) to pull the flexible proximal portion (26) through the loops (15, 24) to attach the load (17) to the garment (10, 30). The stiffened distal portion (27) is then fed back through the loops (15, 24) to provide a geometric lock that prevents the load (17, 18) detaching from the garment (10, 30). Various loads can be attached in this way.

Abstract: A method and system for conducting a group call between a source electronic device (116) and a plurality of destination electronic devices is disclosed. A packet characterized by a first coding technique and destined towards the plurality of destination electronic devices is received. The packet is processed to identify if at least one of the plurality destination electronic devices uses the first coding technique. The packet is then multiplied to form a plurality of packets. The plurality of packets is sent to the plurality of destination electronic devices using the first coding technique. Further, in case at least one of the plurality of destination devices uses a second coding technique, the packet is transcoded to the second coding technique. The transcoded packet is multiplied to form a plurality of transcoded packets. The plurality of transcoded packets are sent to the plurality of destination electronic devices using the second coding technique.

Abstract: For steady state voice data packet transmission between a mobile station and a packet data service node a new compressed TCP/IP header (160) concatenated with a compressed RTP/UDP header (4) is sent. This concatenated header is seven bytes in length instead of the typical 40 byte long RTP/UDP/IP header. A new TCP header arrangement (30) transmits a special access code (161) to a Van Jacobson TCP/IP header compression/decompression arrangement (20). This allows the voice data packet to be transmitted to the receiving end without the other 33 bytes of header information. The PDSN regenerates the IP header and the receiving end then regenerates the RTP/UDP header (205) while it discards the new TCP header arrangement (30).

Abstract: A ground anchor with a floating stabilizer consists of an elongate shaft, a screw flight coupled to the shaft at the lower end and an extension point mounted to the shaft at its lowermost point. A drive handle is provided for rotating the shaft about the axis and threading the flight into the ground. A winged stabilizer member fits over the shaft such that it floats freely of the shaft after installation to accommodate ground heave. An L-shaped mounting member is carried on a threaded rod screwed into a female thread at the top of the shaft for engaging a structure and supporting the structure relative to the ground.
