Abstract:
Methods of operating a cellular radio are provided in which a first power supply signal is transmitted from a power supply to a wireless power unit at least in part over a power cable. A second power supply signal is wirelessly transmitted from the wireless power unit to the cellular radio to power the cellular radio. Data is transmitted from a baseband unit that is associated with the cellular radio to a wireless transceiver at least in part over a data cable. This data is wirelessly transmitted from the wireless transceiver to the cellular radio. The data is then transmitted through an antenna that is coupled to the cellular radio.
Abstract:
Multi-band antennas include one or more duplexers configured to provide isolation of non-linearities generated along a downlink path of RF signals transmitted from the multi-band antenna from an uplink path of RF signals received by the multi-band antenna.

Abstract:
An RF interconnection module includes a housing having a perimeter, a capacitive coupling, and a float gasket disposed about the perimeter of the housing. When the housing is mounted in an opening, the float gasket is positioned between the housing and the opening. The float gasket may be made of an elastomer material and may include a plurality of outwardly extending ribs for movable securing the gasket in the opening. In addition, a mount assembly includes a bracket assembly attachable to a tower-mounted equipment and at least one jumper cable having at least one ohmic connector for connecting to the tower-mounted equipment and at least one capacitive connector. The capacitive connector may comprise an RF interconnection module mounted on the bracket assembly. The bracket assembly may be adjustable to accommodate tower mounted equipment of various sizes.
Abstract:
An optical power detection system comprises a sensor and a reader. The sensor is configured to detect light in the cladding of an optical fiber. The sensor is positioned both within a ferrule of the optical fiber and proximate the cladding. The sensor is additionally configured to produce an output signal representative of the detected light. The reader is electrically coupled to the sensor and is configured to receive the sensor output signal. The reader is additionally configured to operation on the output signal to produce a corresponding visual and/or audible indication of the optical power in the optical fiber.
Abstract:
A direct current (DC) power distribution system is provided. The system includes a passive splitter and an active splitter. The passive splitter includes an input port that is configured to receive a first DC power input and multiple output ports that are configured to provide a first DC power outputs to corresponding ones of multiple power only devices. The active splitter includes an input port that is configured to receive a second DC power input and network data corresponding to at least one network communications data channel and multiple output ports that are configured to provide second DC power outputs and network communications data to corresponding power and/or data devices.
Abstract:
Systems and methods for physical cable route tracing are provided. In one embodiment, a cable comprises: one or more of either electrical conductors or optical fibers; a cable sheath around the one or more of either electrical conductors or optical fibers; and a pattern of cable tracing facilitation markings located on an exterior of the cable sheath; wherein the cable tracing facilitation markings comprise either: a visually varying pattern that gradually changes along a length of the cable sheath; or a series of coded markings of an ordered sequence pattern.

Abstract:
Systems and methods for high efficiency power conversion are provided. In one embodiment, a high efficiency electric power converter circuit comprises: an electric power converter that provides a first electric power output; a storage device that provides a second electric power output; and a power arbitrating switch that receives the first and second electric power outputs and selectively supplies a third electric power output using at least one of the first electric power output and the second electric power output. The switch is configured with a first sensor to measure a charge level of the device and with a second sensor to measure a power demand drawn from the third electric power output. The power arbitrating switch switches the third electric power output between being supplied from the first electric power output and being supplied from the second electric power output based on the power demand and the charge level.
Abstract:
Enclosures are provided having integrated aluminum-ion batteries. The enclosures may include a wall and an aluminum-ion battery that is at least partly integrated within the wall.
