Abstract: A motherboard assembly comprises a motherboard, a first computing component attached to the motherboard, and a coolant container attached to the motherboard. An air-cooled heat sink is attached to the coolant container. The coolant container, the heat sink, and the motherboard form a hermetically sealed enclosure that encompasses the first computing component and that is configured to retain dielectric working fluid covering the first computing component. The heat sink is positioned to condense vapors formed from boiling of the dielectric working fluid and to cause condensed dielectric working fluid to return to a pool of the dielectric working fluid that comprises the first computing component. The motherboard assembly additionally comprises a second computing component attached to the motherboard and positioned outside of the hermetically sealed enclosure.

Abstract: Magneto-optical modulator-based systems and devices for transferring quantum information are described. Such systems can be used for many applications, including as part of quantum computers. An example system includes a quantum information system configured to provide a signal corresponding to at least one qubit.

Abstract: Techniques for mitigating loss of vaporized working fluid in a two-phase immersion cooling system may be implemented using one or more supplemental condensers that facilitate condensation of vaporized working fluid when the immersion tank is open, and one or more vapor collection points that are in fluid communication with at least one supplemental condenser. One or more fluid displacement devices may be configured to create suction pressure at the one or more vapor collection points. One or more vents may be positioned in the door. The one or more vents may be configured to permit movement of air from outside the immersion tank into an interior portion of the immersion tank without permitting loss of vaporized working fluid. A directional blowing device may be configured to blow a gaseous substance against a computing device in a downward direction as the computing device is being pulled upward out of the immersion tank.

Abstract: Techniques are described herein that are capable of performing RFID-based navigation of an autonomous guided vehicle (AGV). An intended location of the AGV is determined based at least in part on a previously determined location of the AGV and further based at least in part on a calculated motion of the AGV from the previously determined location. The AGV includes an RFID device that is paired with RFID devices in an environment of the AGV. The RFID device of the AGV and one or more of the RFID devices in the environment may communicate in accordance with an RFID technique to enable the AGV to determine an actual location of the AGV. A reference location of the AGV on which navigation of the AGV is based is set to be the actual location rather than the intended location.
