Abstract:

Devices, systems, and methods for support structure inspection are provided. In one example implementation, a system can include one or more sensors configured to obtain data associated with a condition of a support structure, such as a utility pole. The system can include one or more processors. The system can include a communication circuit operable to communicate a data packet to a remote device. The data packet can include a payload generated based at least in part on the data associated with the condition of the utility pole. The system can include a power source operable to provide electrical power to the one or more sensors, one or more processors, and the communication circuit.

Abstract:

Multiphase lighting fixtures having one or more light emitting diode (LED) light sources are provided. In one example implementation, a light fixture includes one or more light sources, such as LED light sources. The light fixture includes a power conversion circuit. The power conversion circuit can be configured to receive a multiphase input power comprising three or more alternating current (AC) phases. The power conversion circuit can be further configured to convert the multiphase input power to rectified output for powering the one or more light sources. In some example implementations, the DC rectified output can have a voltage ripple of less than about %, such as less than about %.
