A venting device includes an anchor structure and a membrane. The membrane is anchored on the anchor structure and configured to form a first vent and a second vent. The membrane includes a first flap, a second flap and a third flap. The membrane partitions a space into a first volume and a second volume, and the first volume and the second volume are connected when the first vent and the second vent are formed. The first flap is actuated to move toward a first direction and the second flap is actuated to move toward a second direction opposite to the first direction, so as to form the first vent. The first flap is actuated to move toward the first direction and the third flap is actuated to move toward the second direction opposite to the first direction, so as to form the second vent.

An acoustic impedance measuring system configured to measure an acoustic impedance of an acoustic component includes a first chamber, a second chamber, a first sound pressure sensing device, a second sound pressure sensing device and a sound source. The first sound pressure sensing device is configured to sense a sound pressure in the first chamber. The second sound pressure sensing device is configured to sense a sound pressure in the second chamber. The sound source is connected to the first chamber, wherein the sound source generates a sound propagating towards a first cavity inside the first chamber. The acoustic component is disposed between the first chamber and the second chamber for being measured the acoustic impedance of the acoustic component, and the acoustic impedance of the acoustic component is measured by the first sound pressure sensing device and the second sound pressure sensing device.

Acoustic impedance measuring system and acoustic impedance measuring method

An event trigger and management system for providing automatic repeat requests (ARQs) by a single timer and a method thereof are provided. Various type timers for providing an ARQ are integrated into a single timer. Through a data structure of a timer node of automatic repeat requests time series, the automatic repeat request time series can be managed only by a single timer. Therefore, the efficiency of controlling and managing a timer associated with Worldwide Interoperability for Microwave Access (WiMAX) may be achieved.
