Abstract:
In general, the subject matter described in this disclosure can be embodied in a robotic mowing device that includes a main body, a left-side driving wheel, a right-side driving wheel, and one or more motors to drive the left-side driving wheel and the right-side driving wheel to cause the left-side driving wheel and the right-side driving wheel to turn. The robotic mowing device also includes a deployable propulsion device that includes a rolling member and that is adapted to actuate the rolling member between a deployed state in which the rolling member is adapted to contact the ground surface, and a retracted state in which the rolling member is held apart from the ground surface.
Abstract:
A junction box is affixed to, and electrically coupled with, a solar panel. The junction box is configured to releasably engage and disengage accessory modules, thereby allowing accessory modules to be replaced or exchanged easily. Accessory modules are electrically coupled with other accessory modules in the solar panel string. The furthest downstream accessory module is connected to a wire harness, which is connected to a central combiner box.

Abstract:
A cylindrical guard is used for protecting the electrical junction between connectors. The guard is essentially two split cylindrical sections oriented end-to-end with breakaway tabs therebetween. The split cylindrical pieces are hinged, and substantially irreversibly lock together in a “clamshell” like fashion. The resulting guarded junction is less likely to be accidentally disengaged, thereby protecting both property and life. The guard can be removed by cutting, or broken and moved to expose the underlying junction by severing the breakaway tabs.
Abstract:
Low leakage electrical joints and wire harnesses for simplifying the electrical infrastructure associated with solar energy utilities are disclosed. The low leakage electrical joints include fused wires that have been sealed, encased and configured to plug into other joints to form wire harnesses. The wire harnesses are particularly well suited for coupling a plurality of solar collector junction boxes to a combiner box.
Abstract:
A charging station system is disclosed. In some implementations, the charging station system includes control circuitry and a mechanical arm communicatively connected to the control circuitry. The mechanical arm is configured to adjust a dispensing location of a charging cord. The dispensing location is adjustable to different locations based on at least a first location of a first charging receptacle of a first vehicle and a second location of a second charging receptacle of a second vehicle. The second location is further from a power source than the first location.

Abstract:
A system for monitoring and wirelessly transmitting solar array parameters such as current, voltage and temperature in real time is primarily housed within a recombiner box. The system lends itself to retrofitting within some commercially available recombiner boxes. Signals emitted from the RF controller component of the system are received by a central processor, which includes a dashboard interface. Multiple systems in proximity can be linked to form a mesh network with one central processor.
Abstract:
A lead assembly includes at plurality of drop line joined to a feeder cable at joints each having a compression lug that is preferably surrounded by undermolding and overmolding. In use, each drop line is connected to a solar array, and the feeder cable is connected to an inverter. In this manner a plurality of solar arrays are electrically coupled together, with a common feeder cable connecting them all to the inverter. A system of the present invention doesn't require a combiner box which is conventionally employed directly upstream of the inverter.
