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.

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.
