  • Patent number: 9833374
    Abstract: A training apparatus includes a fixed frame, a training rod, a motor, rotation information detection sensor, tilt angle and position difference calculation units, determination, motor drive and position difference eliminating units. The training rod is supported by the fixed frame in a manner capable of being tilted by a motor about at least an X-axis or a Y-axis so as to hold the limb. The tilt angle calculation unit calculates a tilt angle of the training rod. The position difference calculation unit calculates a position difference. The determination unit obtains the position difference every time when a second time period elapses. If the position difference generated in the second time period is a first threshold or lower, the motor drive unit drives the motor so that the position difference is accumulated and maintained. The position difference eliminating unit resets the position difference at a predetermined timing.

  • Patent number: 9433122
    Abstract: An air conditioner sucks air exhausted from an information processor, and cools down the sucked air. The air conditioner exhausts the cooled air. The air conditioner acquires a cooling state, determines whether a cooling capacity exceeds an upper limit value, and reduces the volume of exhaust air when it is determined that the cooling capacity exceeds the upper limit value. For example, the air conditioner calculates a thermal load as the cooling state by using the volume of exhaust air, a difference between the temperature of exhaust air and the temperature of suction air, and determines that the cooling capacity exceeds the upper limit value when the calculated thermal load exceeds a given threshold. The air conditioner measures the temperature of exhaust air, and determines that the cooling capacity exceeds the upper limit value when the measured temperature exceeds a set value.
