Abstract: A software-based application enables network communication devices in a wireless network to receive and display video from a plurality of network enabled cameras positioned in a plurality of select spaced apart geographic locations. Various types of network enabled cameras may be employed, including disparate cameras manufactured by different manufacturers. In addition, group pre-sets may be created by network administrators for easy access by end-users in the field.

Abstract: A software-based application dynamically updates user lists and enables communication between various network communication devices within a wireless network. The software-based application automatically builds and maintains a list of available users associated with the network communication devices in real-time, without reliance on a centralized server for authentication. Various types of communication, between network communication devices of the wireless network including text-based messaging, audio and video communication and file transfer are performed.

Abstract: In accordance with this invention a compaction unit (100) is provided that includes: (a) an elongated open-ended ramming chamber (50) having a fill port opening (51), a longitudinal bore (52), a compression end (53), and an extrusion end (57), (b) a ramming head (20) pushes material within compression end (53) of ramming chamber (50) along longitudinal bore (52), (c) a continuous homogeneous block (40) comprised of all previously compressed material occupies the bulk of the extrusion end (57) of ramming chamber (50), and functions as an integral part of the compaction unit (100), (d) a hydraulic cylinder (10) (part of an actuator) provides movement to ramming head (20) to compress the loose block-making material (40A) (e.g., earth) against block (40). This forms a new lift (40B) that is effectively fused with the previous lift (40C) to form a continuous homogeneous block (40) of relatively high-density material that exits the compaction unit (100).

Abstract: An apparatus and method is provided for automatically venting a fluid from at least a portion of a pressurized system. An interconnection between two devices in the system contains an automatic bleed valve configured to automatically seal a vent hole when the two devices are coupled together and to automatically unseal the vent hole before the two devices are separated. In an embodiment, an adapter includes a ring that both screws a connector onto a device and seals a vent hole. A pin is pushed into the vent hole as the connector is screwed to the device. To remove the adapter from the device, the ring is turned to both unseal the vent hole and to unscrew the connector from the device. Turning the ring releases the pin before the connector is unscrewed.

Abstract: An energization indicator for a solenoid includes an electrically operable signaler (70) having a coil (72) for energizing the signaler (70) when a magnetic flux field sweeps such coil, with the coil (72) being mounted in the magnetic flux path of the solenoid coil (53).

Abstract: In a Solenoid Operated Pilot Valve, the solenoid plunger serves as a valving element blocking the flow of pilot fluid through orifices disposed at opposite ends of the plunger movement with the plunger being shifted in one direction under the influence of the solenoid coil to block the pilot fluid flow through one orifice and upon de-energization of the solenoid coil the plunger is shifted in the opposite direction by a permanent magnet to block the fluid flow through the orifice at the other end of plunger movement.
