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 for cooling a plurality of devices of a multi-position rack is provided. The system includes a heating, ventilation, and air conditioning (HVAC) unit configured to generate a flow of cooled air, a plurality of sub-ducts, each sub-duct of the plurality of sub-ducts being configured to direct a portion of the flow of cooled air to a respective device of the plurality of devices in the multi-position rack, and a primary duct configured to direct the flow of cooled air away from the HVAC unit to the plurality of sub-ducts, wherein each sub-duct of the plurality of sub-ducts is sized according to a thermal output corresponding to a respective device of the plurality of devices.
