  • Patent number: 10866036
    Abstract: A thermal switch having an on-state and an off-state is provided. First and second plates are composed from a thermally conductive material. The first and second plates are connected to form an internal cavity having a channel defining a gap between the first and second plate. The first reservoir is coupled to the channel and contains a thermally conductive liquid. The actuator is coupled to the first reservoir and the channel and is moveable between a first state and a second state corresponding to the on-state and the off-state of the thermal switch, respectively. Thermally conductive liquid is allowed to flow from the first reservoir to the channel when the actuator is in the first state and allowed to flow from the channel to the first reservoir when the actuator is in the second state.

  • Patent number: 10850856
    Abstract: An aircraft galley compartment cooling system includes a source of chilled air, and a closed compartment with a door. A sensor detects the opening of the door, and sends a signal to the cooling system to deactivate while the door is opened to prevent ambient air from entering the cooling system. Once the door is closed, the cooling system is reactivated. The sensor can be a light sensor, a mechanical sensor, a magnetic sensor, or the like for determining movement or the presence/non-presence of the door to the compartment.

  • Patent number: 10856449
    Abstract: One technique for improving cooling system efficiency is to operate cooling for a data center with a dynamic and distributed cooling system. A distributed cooling system may include multiple compressors operating cooperatively for cooling the data center. A dynamic cooling system may adjust operation of the compressors based on one or more parameters, such as inside temperature, outdoor temperature, inside humidity, outside humidity, and load on the data center. By appropriately controlling speeds of the compressors, the power efficiency of the cooling system may be improved by ensuring that all activated compressors are operating within their efficient operating range. By doing so, the cooling system may be controlled to obtain an approximately linear power consumption as a function of cooling load.

  • Patent number: 10845086
    Abstract: An air-conditioning control device for controlling an air-conditioning apparatus configured to perform air conditioning of a room in which a device that changes an amount of water vapor is located. The air-conditioning control device includes a condensation occurrence determiner configured to determine whether condensation occurs in the room after a certain amount of time elapses by using an amount of change in water vapor, which is predicted by collating device operation data with a device operation table, and an air-conditioning controller configured to change an operation state of the air-conditioning apparatus when the condensation occurrence determiner determines that condensation occurs.

  • Patent number: 10845375
    Abstract: A thermal stabilization system stabilizes inertial measurement unit (IMU) performance by reducing or slowing operating variations over time of the internal temperature. More specifically, a thermoelectric heating/cooling device operates according to the Peltier effect, and uses thermal insulation and a mechanical assembly to thermally and mechanically couple the IMU to the thermoelectric device. The thermal stabilization system may minimize stress on the IMU and use a control system to stabilize internal IMU temperatures by judiciously and bidirectionally powering the thermoelectric heating/cooling device. The thermal stabilization system also may use compensation algorithms to reduce or counter residual IMU output errors from a variety of causes such as thermal gradients and imperfect colocation of the IMU temperature sensor with inertial sensors.
