Abstract: A cooling device for electronic components has a main body, a motor, an adaptor tube, a shaft, a valve assembly, a reservoir, and a delivery tube. The motor is mounted in the main body. The adaptor tube is mounted between the main body and the reservoir and is gradually smaller in diameter from the main body to the reservoir. The shaft connects to the motor, extends into the adaptor tube and has multiple fan blades corresponding to the inside diameter of the adaptor tube. The fan blades blow the air through the adaptor tube into the reservoir to pressurize the air. The pressurized air flows through the delivery tube to contact the electronic component and equalizes to correspond to the atmosphere. The equalizing process of the pressurized air absorbs heat from the electronic component as it expands to cool the electronic component.

Abstract: An integrated tuner includes circuitry to receive a television signal, a quadrature mixer coupled to the output of the circuitry, a polyphase filter coupled to the output of the quadrature mixer, a relaxation oscillator, and a digital calibration module. The relaxation oscillator generates a clock having a period that is directly proportional to the on-chip RC time constant. The clock is fed into a counter of the digital calibration module.

Abstract: A packet transmission method for WLAN, a controlling method for data transmitting node of WLAN and a controlling method for data receiving node of WLAN are provided. In the packet transmission method, the data transmitting node sends a transmitting request signal. When the receiving node receives the transmitting request signal and cannot immediately perform a transmitting operation defined by the transmitting request signal, a stop-transmitting signal is sent to the transmitting node. After sending the stop-transmitting signal, the receiving node outputs a start-to-transmit signal to the transmitting node when the transmitting operation can be performed. The transmitting node sends the data after receiving the start-to-transmit signal.
