  • Patent number: 10869037
    Abstract: To provide a data encoding system that can control compression parameters when compressing sensing data in a flying object without setting a compression method in advance. The data encoding control device installed in a ground station detects a position on earth sensed by the sensor, determines information about a compression parameter of sensing data acquired through sensing performed by the sensor, based on the detected position, and notifies, to the data encoding device, the information about the determined compression parameter. The data encoding device acquires the information about compression parameter notified from the data encoding control device, and compresses sensing data acquired through sensing performed by the sensor, according to the acquired information about the compression parameter.

  • Publication number: 20200355406
    Abstract: A part of a gas-phase mixed refrigerant compressed by a compressor (20) is condensed by a first condenser (21). Then, the mixed refrigerant is separated by a first gas-liquid separator (22) into a gas-phase first fluid portion (I) and a liquid-phase second fluid portion (II) which has been condensed into a liquid phase. A part of the gas-phase first fluid portion (I) is further condensed by a second condenser (23). Then, the first fluid portion is further separated by a second gas-liquid separator (24) into a gas-phase third fluid portion (III) and a liquid-phase fourth fluid portion (IV) which has been condensed into a liquid phase. Thereafter, the gas-phase third fluid portion (III) is condensed and then expanded.
