In one embodiment, a device for coupling communications signals onto a medium-voltage power line includes a first connector, a second connector and one or more components. The first connector is adapted to couple to a low-voltage communications line. The second connector is adapted to couple to a surge arrester. The one or more components are operable to substantially match the impedances between the surge arrester and the low-voltage communications line.

A cable management arm assembly includes a frame, a support rail, a first and a second sliding members, a first and a second connectors, and an insertion socket operating in conjunction with slides. The frame slides on the support rail with both ends connected to the insertion socket and the first connector. The sliding members are respectively mounted in the connectors. A locking member is disposed on each of the connectors and the insertion socket to secure them to the slides. A limiting member is provided on the first connector connected to the frame to retain and release the first sliding member, and the limiting member is pushed when the first connector is inserted into the rear end of the outer rail to release the first sliding member for the support rail to move when the slides extend and the front and the rear arms of the frame unfold.

A fluid loss detection device for dressings at pre-existing port sites, catheter sites, operative sites, ostomy sites, drain sites, line sites such as those utilized in hemodialysis, wound sites, or other areas for which monitoring of fluid or blood loss is medically indicated. The detection device includes a patch having a primary loop circuit and an early warning alarm circuit loop. In one embodiment, closure of the early warning alarm circuit loop activates an alarm. The alarm may be connected directly to the patch and sound locally or may be activated remotely via radio transmission. The detection device may additionally cause a medical device such as a hemodialysis system to shut down.

Floorboards with a format corresponding to a traditional parquet block for laying of mechanically joined floating flooring. Rectangular floorboards include a surface layer and a core with two long sides and two short sides, for making a floating flooring, which floorboards are mechanically lockable and which along their four sides have pairs of opposing connectors for locking similar, adjoining floorboards to each other both vertically and horizontally wherein the long sides have a length not exceeding 80 cm and the short sides have a width not exceeding 10 cm.

A communication system providing wireless communication among wireless users through a number of cellular base stations. At least one of the base stations is a mobile base station in which low and high speed wireless transceivers are mounted on a temporarily stationary mobile vehicle such as a truck trailer or a truck. The system includes at least one connecting station with a millimeter wave wireless transceiver in communication with a fiber optic or high-speed cable communication network. The transceiver is adapted to communicate at millimeter wave frequencies higher than 60 GHz with another millimeter wave transceiver at one of the cellular base stations. Each of the base stations serves a separate communication cell. Each base station is equipped with a low frequency wireless transceiver for communicating with the wireless users within the cell at a radio frequency lower than 6 GHz and a millimeter wave wireless transceiver operating at a millimeter wave frequency higher than 60 GHz for communicating with another millimeter wave transceiver at another base station or a millimeter wave transceiver at said at the connecting station. The base stations are also equipped with data transfer means for transferring data communicated through the low frequency wireless transceiver to the millimeter wave wireless transceiver and for transferring data communicated through the millimeter wave wireless transceiver to the low frequency wireless transceiver. In preferred embodiments the system is a part of a telephone system, an Internet system or a computer network.
