    Abstract: A vale unit includes a valve frame and two valve plates. The valve frame defines a valve opening. The valve plates are formed with protrusions. Each of the valve plates has a connecting end that is formed with a notch. The connecting ends are connected to each other. The protrusions protrude from peripheries of the notches. Each of the protrusions has a contact end. The contact ends cooperatively define a gap therebetween. The valve plates are co-rotatable about an axis between a closed position, in which the valve plates substantially close the valve opening, and an opening position, in which the valve plates open the valve opening. The gap has a width varying in response to co-rotation of the valve plates between the opening position and the closed position.

  • Patent number: 9698721
    Abstract: AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.

  • Publication number: 20170007789
    Abstract: An extendable air delivery system and a method for deciding a delivery mode therein are provided. The extendable air delivery system includes a PAP device for supplying a breathable pressured air to a patient and a sensing device to acquire physiological information from the patient by at least a sensor. The PAP device has two operations modes which are exchangeable while the air is supplied to the patient based on the connection or disconnection of the sensing device. When the sensing device is not connected to the PAP device, the PAP device enters a preset independent operation mode and performs a preloaded first air delivery behavior. When the sensing device is not connected, the PAP device enters a common operation mode, and during the common operation mode, based on the acquired physiological information, the sensing device generates a signal/data for deciding a second air delivery behavior of the PAP device.
