Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

Abstract: A short pulse generating circuit including a pulse generating circuit, an actuation control circuit and a delay control circuit is provided. The pulse generating circuit is electrically coupled to a switch, which is coupled to a power. When the power is turned on, the power causes the pulse generating circuit to generate a long pulse. The actuation control circuit is electrically coupled to the power and the pulse generating circuit. When the power is turned on, the actuation control circuit controls a voltage level of each output of the pulse generating circuit to a fixed value. The delay control circuit is electrically coupled to the pulse generating circuit. When the switch is turned on, the power controls the delay control circuit to change the voltage level of each output of the pulse generating circuit to generate a short pulse output.

Abstract: An air condition system includes a casing, a first heat exchanger, a fan and a second heat exchanger. A host is held by the casing. The first heat exchanger is disposed inside the casing. Air flows into the casing, and is processed by the first heat exchanger. Then, the air processed by the heat exchange procedure flows forward the host. The fan exhausts the air passing through the host. The second heat exchanger disposed on the fan and inside the casing. The air exhausted by the fan is processed by the second heat exchanger, and flows out of the casing by wind force of the fan.
