Abstract: A power transmission system is disclosed comprising a centralized power supply system having multiple DC power supply units and a controller coupled to the DC power supplies. Remote devices are coupled to the centralized power system via a power cable. In some embodiments, each of the DC power supply units transmit signal information to respective ones of the remote devices, and the remote devices may be configured to forward the signal information to the controller. In some embodiments, the controller module automatically allocates individual ones of the DC power supply units to the respective ones of the remote devices based on the forwarded signal information.

Abstract: A power boost retrofit system for a power communications system having an existing base overvoltage protection unit, where one end of DC power cables is connected to remote radio heads (RRHs).

Abstract: A remote suppression unit retains a first set of surge suppression modules. A base suppression unit retains a second set of surge suppression modules. An over voltage protection (OVP) board in the remote suppression unit includes power strips that couple the first set of surge suppression modules to remote ends of DC power cables. A configurable terminal assembly in the base suppression unit couples the second set of suppression modules to local ends of the DC power cables. The surge suppression modules in combination with the OVP board and terminal assembly provide more suppression protection in both the remote and base suppression units. A remote voltage monitor circuit in the remote suppression unit measures voltages on remote ends of the DC power cables and transmits the voltages and alarm status to a monitor circuit in the base suppression unit.

Abstract: A power transmission system includes a voltage measurement device located on a tower or rooftop for measuring a voltage (VRRH) at a top end of a DC cable connected to a remote radio head (RRH). A voltage control system receives an input voltage (VIN) from a DC power supply and generates an output voltage (VOUT) at a base end of the DC cable. The voltage control system calculates a voltage drop on the DC cable based on the VRRH measurement and then adds different voltage steps to VIN so VOUT compensates for the voltage drop. Calculating the voltage drop allows the PTS to more efficiently supply power to RRHs without having to increase the size of DC power cables.

Abstract: A method for incorporating a set of requirements into an executable program to be run on an airborne system is provided. The method obtains the set of requirements for the program in a first format. The method uses a first tool to convert the set of requirements in the first format into a second format utilizing a markup language. The method uses a second tool to convert the set of requirements in the second format into a third format that influences a behavior of the program without changing the program. The method uses a third tool to determine whether the set of requirements in the third format incorporates all of the set of requirements in the second format in order to verify the program under a compliance standard for the airborne system without performing a verification process directly on the program.

Abstract: A suppression system provides more effective protection for communication stations with distributed radio and power systems. The suppression system provides surge protection both locally close to the radio station building where the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. Local and remote suppression units may include monitor circuitry that monitor remote and local DC voltage levels and alarm conditions. The alarm conditions may include over-voltage protection failures, intrusions, and/or water infiltration. Displays on both the local and remote suppression units identify the voltage levels and alarm conditions.

Abstract: Calls made to a communication unit from the telephone network include a code which can be appended as a predetermined prefix or suffix to the units address code, for alerting the operator that the call was made from the telephone network. Conversely, calls made to the communication unit from another communication unit do not include the code thereby alerting the operator that the call was made from a communication unit. The alert can be accomplished by using visual indicators or and alphanumeric display and/or can be accomplished by use of two distinct audible signal.
