  • Publication number: 20190337145
    Abstract: A remotely controlled packable robot features a chassis with a top surface and a bottom surface, a pair of main tracks for maneuvering the chassis, and an open channel under the robot defined by the bottom surface of the chassis and the main tracks. A robot arm is foldable from a stored position in the open channel underneath the robot chassis to a deployed position extending upwards from the top surface of the chassis. A camera assembly may be foldable from a stowed position in the open channel underneath the robot chassis next to the robot arm to a deployed position extending upwards from the top surface of the chassis.

  • Patent number: 10331132
    Abstract: A battery powered remotely controlled robot is equipped with a drive subsystem for ground travel, a flight subsystem for flight operations, and an obstacle detection subsystem. The robot is configured so that during a mission the drive subsystem is energized to maneuver the robot on the ground for a majority of the mission. The robot is further configured so that upon detection of an obstacle, the flight subsystem is energized to traverse the obstacle. The fight subsystem is energized only to traverse obstacles thus saving battery power and increasing the mission time.

  • Publication number: 20160370408
    Abstract: An ungrounded power line sensor system includes a housing configured for coupling about a power line, at least a first voltage sensing plate supported by the housing and exposed to rain and snow, and at least a second voltage sensing plate supported by the housing and shielded from rain and snow. Voltages sensed by the first and second voltage sensing plate are separately measured in order to mitigate variations in the two measurements due to a weather event, for example by applying a weighted average calculation to the measurements to cancel out the effects of rain on the first voltage sensing plate.

  • Patent number: 9347976
    Abstract: A hot stick power analyzer includes a housing mounted on a pole and a channel for a power line. A ground line extends from the housing and there is a power line conductive contact. A voltage sensor includes voltage sensing circuitry connected to the power line conductive contact and the ground line. There is a high voltage capacitance between the ground line and the voltage sensing circuitry. A current sensor includes windings about and spaced from the power line. A processing subsystem is responsive to the voltage sensing circuitry and to the current sensor and is configured to compute power analysis metrics.

  • Patent number: 9347972
    Abstract: A voltage sensing system and method for use with ungrounded power line sensors deployed on each phase of a power line. The voltage of each phase is measured using the sensors. This measurement is used unless there is a snow event. A collector is powered by a transformer connected to the power line being monitored and a voltage measurement circuit is configured to measure the collector supply voltage which is then used to obtain an alternate voltage measurement for each phase. When the sensor measured voltage for any phase deviates from the alternate voltage measurement by a pre-established value, a snow event has occurred and the alternate voltage measurement may then be used.
