Abstract: A system for detecting and locating sand accumulation in an enclosure and for removing the detected and located sand accumulation, having a sand accumulation locator assembly adapted to detect and locate one or more accumulations of sand in the enclosure; a sand removal mechanism adapted to remove the detected one or more accumulations of sand; and a controller communicatively coupled to the sand accumulation locator assembly and the sand removal mechanism, said controller being adapted to: control the sand accumulation locator assembly to detect and locate the one or more accumulations of sand in the enclosure; and control the sand removal mechanism to remove the one or more detected accumulations of sand based on corresponding one or more locations of accumulated sand detected by the sand accumulation locator assembly.

Abstract: A system includes: a TX port and a RX port; an omnidirectional TX antenna connected to the TX port; a plurality of RX antennas connected to the RX port, wherein each RX antenna comprises a first antenna element and a second antenna element; a monitoring circuit connected to the TX antenna; a switching circuit connected to the second antenna element of each RX antenna; and a processor connected to the monitoring circuit and to the switching circuit. The monitoring circuit monitors a status of the TX antenna. In response to a failure of the TX antenna detected by the monitoring circuit: the monitoring circuit notifies the processor of the failure; and the processor controls the switching circuit to switch the second antenna element of each RX antenna to be connected to the TX port. When the failure is not detected, the second antenna element of each RX antenna is disconnected from the TX port.

Abstract: In an example method, a power management system receives sensor data regarding an operation of a primary power source, a secondary power source, an environmental regulation system, and a plurality of electrically-powered sub-systems. Further, the system receives a plurality of parameter sets for the sub-systems, each including a first parameter indicting a priority of a respective sub-system relative to the other sub-systems, a second parameter indicating an amount of heat dissipated by the respective sub-system during operation, and a third parameter indicating a temperature requirement associated with the respective sub-system. The system controls, based on the sensor data and the parameter sets, a delivery of electrical power from the primary and secondary power sources to the environmental regulation system and the sub-systems. Further, the system controls, based on the sensor data and the parameter sets, a consumption of electrical power by the environmental regulation system and the sub-systems.

Abstract: A method of ventilating a battery room comprises detecting a hydrogen concentration in the battery room, determining whether the hydrogen gas concentration is at or above a first threshold concentration, activating two or more exhaust fans to ventilate the battery room simultaneously when the battery charging process is triggered or when the hydrogen gas concentration is at or above the first threshold, and identifying a location in the battery room at which hydrogen is being released. In certain embodiments, notifications are generated and provided concerning the identified location in the battery room at which hydrogen is being released.
