Abstract: A method of remotely locating a mobile device equipped with a radio receiver by remotely and securely activating the device's ringer and location system, and communicating such location to the device owner.

Abstract: An armor system for protecting an object from the impact of a projectile. A core layer of hardened metal or ceramic balls supported in a softer material, wherein the surfaces of the balls are in contact with adjacent ball surfaces and the sizes of the balls are selected with respect to the anticipated shape of the projectile being armored against. Inward and outward facing reinforced layers at the surfaces of the core layer. The reinforced layers including a resin base and fibers therein. A backing plate may back the core layer on the rear surface.

Abstract: The present techniques provide a method for making wear surfaces comprising a thermoplastic matrix blended with ceramic particles. The wear surfaces may optionally contain other materials, such as friction modifying additives. Wear surfaces formed according to these techniques may be used to protect such surfaces as the side rails of conveyor belts, the teeth of buckets used on front end loaders, rock or debris chutes, and self dumping hoppers, among others.

Abstract: The present techniques include a field armor system comprising hollow structures designed to be filled with field materials, such as soil, sand, rocks, or clay. At least one face of the structures is made from a projectile resistant plastic composite. The projectile resistant plastic composite panel may be made from a ceramic plastic composite, a fiber plastic composite, or interspersed layers of both. In one embodiment, the hollow structure comprises four connected panels that may be collapsed when empty. In another embodiment, the hollow structure may comprise hollow bricks designed to interlock to form a protective wall.

Abstract: A paging system in which a subscriber's telephone number is used as the PIN number to identify the subscriber's pager. When a caller places a call to the paging system, the caller enters the telephone number of the subscriber when prompted for a PIN. The paging system performs a database lookup to determine the address of the pager associated with the entered PIN. Alternatively, the entered PIN itself could be used as the address of the pager. Upon identification of the address of the pager, the paging system transmits a message including the address of the pager via radio transmission.

Abstract: A method and apparatus for reducing the cost of an RF base station that services a location where real estate is expensive without reducing the capacity of the system, subjecting the system to significant environmental interference, or purchasing additional licensed frequency spectrum. In accordance with the present invention, communication between two sections of an RF base station of a wireless communication system is implemented using an over-the-air optical link, also referred to as a wireless optical link. In particular, wireless RF communication equipment of either, or both, 1) the RF antenna and RF hardware, and 2) the processing and/or control section of the RF base station is coupled to over-the-air optical communication equipment. Overall, the present invention allows an RF base station to service the location where real estate is expensive at a much lower cost without reducing the capacity or the signal quality of the system.

Abstract: On instructions obtained from a subscriber, a wireless terminal service provider sends a power-down signal to a wireless terminal. Upon receipt of the power-down signal, the wireless terminal goes into a sleep state. In this state, all monitoring functions other than time, date and elapsed time are turned off. The power-down signal sets a clock, which can be located within the wireless terminal, to awaken the wireless terminal at the end of a discrete interval of time by powering-up the monitoring circuits. The wireless terminal service provider, by knowing the power-down/power-up time cycle of the wireless terminal, can alert a party attempting to contact the wireless terminal during the power-down period that the called party cannot be reached.

Abstract: A cabinet includes a hinged tracking system for attaching a door to the cabinet. The hinged tracking system allows the door to translate rectilinearly away from the cabinet, as well as rotate with respect to the cabinet. The hinged tracking system includes a track member attached to a side wall of the cabinet, and a slide member slidable with respect to the track member. An intermediate member may be disposed between the track member and the slide member to increase the linear travel of the slide member. A hinge is located between the slide member and the door. The track member and the slide member may include stoppers which prevent overtravel of the slide member with respect to the track member, so that the slide member does not inadvertently slide completely off of the track member. The slide member may also include a locking system for locking the slide member in a maximum extended position, and for locking the hinge in a closed position or an open position.

Abstract: A power connector for receipt and releasable engagement with a wire to effect a transmitting power electrical connection to the wire. The power connector includes a connector housing having a wire insertion side with an opening for receiving the wire. A spring contact is disposed within the housing and includes an attachment end for attaching the spring contact to the connector housing and a contact end for contact with the wire. The spring contact includes a substantially C-shaped segment extending between the attachment end and contact end. The C-shaped segment is dimensioned to be maintained under compression and so that the spring contact applies a contact force against an inserted wire at the contact end with a force sufficient for supporting the conducting of electricity between the wire and contact end.

Abstract: A mounting assembly includes a metallic base member, such as a wall of an enclosure. A threaded stud is fused to the base member. A threaded collar engages the threaded stud and provides a threaded recess for receiving a mounting fastener. The mounting assembly is well-suited for supporting electronic items within an enclosure in a weather-tight or water-proof manner because the mounting assembly requires no seals for an environmental barrier.
