Abstract: A comprehensive dry flood proofing solution to mitigate inland flooding risk for existing or new homes and small buildings. The integrated house wrap system of the present disclosure leverages the building's structure to offer practical and affordable flood protection for those buildings constructed with slab-on-grade foundations. The components of the solution are reusable, easy to deploy, and do not detract from the building's permanent appearance. Furthermore, the solution allows for ingress/egress during flood events and can protect the building from standing water incursion up to 24? above slab elevation. The pre-flood design and preparation, the deployment immediately preceding flooding event and the subsequent removal after flooding event has passed is provided by both contractors and homeowners.

Abstract: A location detection system for locating a mobile device placing an emergency 911 call within a facility having a distributed antenna system. The location detection system includes one or more detection units located within the distributed antenna system and being associated with one or more antennas. Each detection unit monitors a dedicated emergency 911 channel for activity and alerts a monitor unit if activity is detected. The monitor unit determines the location of the antenna receiving the emergency 911 call based upon the identity of the detection unit.

Abstract: A method and system for detecting whether an antenna is property connected to a distributed antenna network. The current drawn by the antenna is measured and compared against an expected current draw or reference level. The measured level of current drawn by the antenna is indicative of whether the antenna is properly connected or is disconnected. The comparison results may be used as the basis for creating a status message, which is then communicated to a central monitoring unit for each antenna. The central monitoring unit may generate appropriate alarms in response to a status message indicating a fault condition at a particular antenna.

Abstract: A distributed antenna system for providing distributed signal coverage within a facility of one or more wireless networks transmitting one or more RF signals. The distributed antenna system comprises a wireless base station configured to extend coverage of the one or more wireless networks; a backbone coupled to the base station; a plurality of coupler units connected to the backbone; a first plurality of antennas, each connected to one of the coupler units; a plurality of amplifiers coupled to the backbone; and a second plurality of antennas, each connected to one of the amplifiers. The plurality of amplifiers and the second plurality of antennas actively distribute the one or more RF signals during a powered condition and the first plurality of antennas passively distributes the one or more RF signals during a power failure.

Abstract: A magnetically controlled flow system having a pivotable flap with a permanent magnet at distal ends. Two coils with magnetizable cores are mounted inside the duct and positioned so as to cooperate with the permanent magnet when the flap is in either a closed or an open position. By energizing the coils, the permanent magnet is attracted to the magnetizable cores in either one of the coils, thereby actuating the flap between the closed and open positions.

Abstract: A radio frequency communication system utilizing a radiating transmission line for simultaneously communicating audio and video signals is disclosed. The video signals convey video information and the audio signals convey narrow band computer data or audio information. The communication system also provides several separate channels allowing simultaneous audio communication between a plurality of mobile stations. The communication system is intended to be used in environments where radio waves do not propagate well, such as in underground mines. The communication system comprises at least one amplification unit connected to the radiating transmission line for periodically amplifying the audio and video signals. The amplification units have a separate amplifier for amplifying each of the signals and each amplifier is connected to the transmission line in parallel. The amplifiers utilize transistors operating in the linear region.

Abstract: A connector which may be connected to a fitting, such as a CATV outlet, without the use of a tool, but which requires a tool for removal of the connector from the fitting. The connector comprises an outer body and an inner rotatable shell with a one-way driving means therebetween. A special tool is disclosed for uncoupling the connector from the fitting.
