Abstract: In certain embodiments, a weapon station comprises a weapon mounting apparatus and a sight mounting apparatus. The weapon mounting apparatus is adapted to rotate, using a first rotational drive mechanism, about an azimuth axis. The weapon mounting apparatus is adapted to receive one or more weapons for attachment at a position offset from the azimuth axis. The sight mounting apparatus is coupled to the weapon mounting apparatus and is adapted to receive for attachment a sighting device. The sighting device comprises one or more sensors and is adapted to rotate, using a second rotational drive mechanism, the one or more sensors about the azimuth axis independently of rotational movement of the weapon mounting apparatus about the azimuth axis. The azimuth axis about which the weapon mounting apparatus and the one or more sensors rotate is a common azimuth axis.

Abstract: Methodologies and structure are provided for use in a communications line that transmit data without plain old telephone service (POTS), or splits the POTS service from the data service, to inhibit oxidation of electrical connections within the physical communications line between the central office of a service provider and a subscriber premises and/or subscriber equipment. A direct current load is drawn by a sealing current terminator circuit that is electrically coupled across the communications line at a convenient location proximate or within the subscriber's location so as to assist in providing oxidation reducing direct current flow along a portion of the communications loop coupling the service provider with the subscriber.

Abstract: An apparatus and method is provided for permitting a service provider technician or subscriber to install a twisted wire pair to coax adapter within a network interface device (NID) at a subscriber premises. The twisted wire pair to coax adapter is configured for snap-in mounting within a NID. The adapter includes input and output connections, as well as an internally disposed balun, and is configured to convert communications signals carried on a twisted wire pair to communications signals carried on a coax cable to avoid degradation of the signals resulting from the use of an unshielded twisted wire pair within a subscriber premises.

Abstract: A central office surge protector having at least one gas tube and at least one varistor. The at least one varistor interacts with the at least one gas tube to lower the impulse breakdown voltage of the gas tube. The at least one gas tube may be a two or a three element gas tube. Alternative embodiments of the surge protector further include at least one sneak current protection element.

Abstract: A surge protector having a failsafe mechanism including at least one overvoltage protection element, at least one arm assembly, at least one ground element, at least one resilient member, and at least one protrusion. The at least one resilient member is electrically connected to the at least one ground element and the at least one protrusion is generally positioned between the at least one resilient member and the at least one arm assembly. The at least one protrusion is in thermal contact with the at least one resilient member, prevents the at least one resilient member from electrically contacting the at least one arm assembly during normal operation, and is spaced away from the at least one arm assembly.

Abstract: A terminal block for mounting on a distribution frame in a telecommunications network includes a base defining a generally planar front surface and a generally planar rear surface opposite the front surface. A plurality of pairs of conductive terminals extend outwardly from the front and/or the rear surfaces of the base. An opening formed in the base is disposed between each pair of terminals. A dielectric plug is positioned and retained within the opening for reciprocal movement between a first position wherein the pair of terminals are electrically disconnected and a second position wherein the pair of terminals are electrically connected. The terminal block provides a quick connect/disconnect capability in the cross-connect field, thereby increasing the capacity of the terminal block, while substantially reducing or eliminating the possibility that connections on the terminal block will be inadvertently disconnected.
