  • Apparatus for interconnecting multiple nodes
    Patent number: 6561827
    Abstract: The present invention describes a patch panel unit including an interface for connecting the patch panel with an electrical node and first and second ports for receiving patch cord connectors. A switch interconnects the first interface with the first and second ports such than when a connector is placed only within the first port, an active connection is provided between the interface and the first port. When a connection is placed within the second port, an active connection is provided between the second port and the first interface despite whether a connection is provided with the first port.

  • Simulated air interface system for simulating radio communication
    Patent number: 5465393
    Abstract: A simulated air interface system repeatedly simulates a constant but variable open air environment. In the system, a plurality of mobile stations are connected to at least one base station by cables. The system separates the radio path at each mobile station's antenna into an uplink path and a downlink path so that frequency modulation and signal reflections are not introduced into the system. The conditions of the simulated open air environment can be varied by introducing attenuation, doppler shifts, and signal fading into the system.
