  • Patent number: 10256770
    Abstract: A system and method for automated shutdown, disconnect, or power reduction of solar panels. A system of solar panels includes one or more master management units (MMUs) and one or more local management units (LMUs). The MMUs are in communication with the LMUs with the MMUs and LMUs “handshaking” when the system is in operation. The MMUs are connected to one or more controllers which in turn are connected to emergency detection sensors. Upon a sensor detection of an emergency, the associated MMU is notified which in turn instructs associated LMUs to take appropriate action. In the event that communication with the MMUs has been cut off, the LMUs take the initiative to shut down, disconnect, or reduce the output of associated string(s) of solar panels.

  • Patent number: 10230276
    Abstract: Various embodiments use prospective synchronization signals early in the signal reception to adjust framing cycles of communication nodes to reduce jitter. Some embodiments temporarily suspend messaging between existing nodes of a communication system while instructing new nodes to generate a beacon according to a beacon schedule. The system can monitor for responses from the new node and calculate a timing error. This timing error can be sent to the new node to adjust cycle framing. In some embodiments, these techniques for timing the receive (Rx) and transmission (Tx) cycles of a node (e.g., a client wireless antenna system) can be utilized such that the radio frequency (RF) energy received between RF energy cycles can be delivered directly to the node, stored in a client's battery by a wireless charging system, enhance the Rx signal opportunities, or make the integrity of the delivered Tx signal more efficient.

  • Patent number: 10214115
    Abstract: A multiple EVSE installation employs a power sharing system for EVSE pairs which share a common circuit breaker. When only one EVSE is connected to an electric vehicle for charging, the connected EVSE is allowed to charge at full capacity. When a second EV connects to the second EVSE of the pair, while the first EVSE is charging, a controller senses the latter event and issues commands to both EVSE units to limit their current so that the rated circuit breaker capacity is not exceeded. The controller continuously monitors the charging of each of the EVSE units and sends commands to adjust the supply of current to each EVSE accordingly.
