Abstract: An outdoor unit includes a pressure sensor for detecting an internal pressure of a first pipe. An outdoor unit controller is configured to: receive a switching signal; control an outdoor fan and a compressor to operate in a case where the switching signal instructs the outdoor unit to operate, the compressor operating at a first frequency; acquire a current state of the indoor fan in a case where the on signal instructs the outdoor unit to shut down; and control the compressor and the outdoor fan to operate if the current state of the indoor fan is an operating state, the compressor operating at a second frequency. The second frequency is lower than the first frequency. The current state of the indoor fan is obtained according to the internal pressure of the first pipe.

Abstract: An air conditioner and a method for controlling air conditioner communication are disclosed. The air conditioner includes an indoor unit, an outdoor unit, and a temperature protector. The indoor unit includes an indoor control device and an indoor communication device. The outdoor unit includes an outdoor control device and an outdoor communication device. The temperature protector includes a temperature control device and a temperature control communication device. The temperature control device is configured to output a temperature control setting parameters. The temperature control communication device is coupled with the temperature control device.

Abstract: An apparatus for cup loading and unloading and a thromboelastography machine are provided. The apparatus for cup loading and unloading includes a base, a shaft, a movable cover, and a cup holder. The shaft is rotatably connected to the base about an axis of the shaft and has an end configured to engage with an inner cup. The movable cover is disposed around the shaft and slidably connected to the base along the axis of the shaft. The movable cover is provided with an elastic member therein. The cup holder is slidably connected to the base along the axis of the shaft and disposed below the base and the shaft. The cup holder has a cavity configured to engage with an outer cup, and the cavity has an open directed upward.
