Abstract: A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. A first chamber is formed between the resonance plate and the piezoelectric actuator. After a gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device includes a valve film and a gas outlet plate. After the gas is transferred from the miniature fluid control device to the miniature valve device, the valve opening of the valve film is correspondingly opened or closed and the gas is transferred in one direction. Consequently, a pressure-collecting operation or a pressure-releasing operation is selectively performed.

Abstract: A three-dimensional integrated circuit cooling system is provided for removing heat from a three-dimensional integrated circuit. Plural fluid microchannels are formed among plural middle chip layers and a main chip layer of the three-dimensional integrated circuit. The three-dimensional integrated circuit cooling system comprises a base and a fluid pump. The base has an introduction opening, a discharge opening and a fluid passage. The fluid pump is fixed on the base and seals the edge of the introduction opening. When the fluid pump is enabled, an ambient fluid is driven by the fluid pump, introduced into the fluid passage through the introduction opening, and discharged through the discharge opening. The discharged fluid passes along every fluid microchannel of the three-dimensional integrated circuit as flowing through the plural middle chip layers and the main chip layer so as to perform heat exchange therewith.

Abstract: A positive airway pressure apparatus is disclosed and includes a mask, a micro pump and a processor. The mask is fastened on a user's face and is spatially corresponding to an airway opening of the user, so as to form a closed space. The micro pump is assembled with the cover and is in fluid communication with the exterior of the mask. The processor transmits an actuation control signal to the micro pump so as to actuate the micro pump. Consequently, air is transported into the closed space from the exterior of the mask, and a positive pressure airflow is formed and flows into the airway of the user. A pressure sensor is disposed within the closed space to detect the pressure of the closed space, so that the processor can determine the respiratory state of the user and control the air pressure output of the micro pump correspondingly.
