Abstract: A thin profile gas transporting device includes a gas collecting plate, a valve sheet, a discharge sheet, and a gas pump. The gas pump is disposed on the gas collecting plate. The gas collecting plate, the valve sheet, and the discharge sheet are stacked and assembled sequentially. Through simplifying the structures of the gas collecting plate and the discharge sheet, the thicknesses of the gas collecting plate and the discharge sheet can be reduced. Moreover, through the arrangement of several pressure relief holes, the pressure relieving operation can be performed rapidly and quietly.

Abstract: A miniature piezoelectric pump module is provided and includes a piezoelectric pump, a microprocessor, a driving component and a feedback circuit. The piezoelectric pump includes two electrodes and a piezoelectric element and has the best efficiency while operating under an ideal operating voltage. The driving component is electrically connected to the microprocessor and the piezoelectric pump and includes a transform element and an inverting element. The transform element outputs an effective operating voltage to the piezoelectric pump. The inverting element controls the two electrodes to receive the effective operating voltage or to be grounded. The piezoelectric element is subjected to deformation for transporting fluid due to piezoelectric effect. The feedback circuit generates a feedback voltage according to the effective operating voltage. The microprocessor adjusts the modulation signal according to the feedback voltage for adjusting the effective operating voltage outputted by the transform element to approach the ideal operating voltage.

Abstract: A gas detecting device includes an actuating-and-sensing module, a driving controller, a data storage device and a data processor. The actuating-and-sensing module includes a first gas sensor, a second gas sensor and a gas transportation actuator. The driving controller controls the actuations and non-actuations of the first gas sensor, the second gas sensor and the gas transportation actuator. The first gas sensor measures the target gas and transmits first gas measured information to the data storage device. The second gas sensor measures the target gas and transmits second gas measured information to the data storage device. The data processor calculates concentrations of the gases in the target gas by comparing the information stored in a gas database, the first gas measured information and the second gas measured information.
