Abstract:
The present invention discloses a frequency-changing voltage regulation circuit, which applies to a power supply device that has a booster unit and a power conversion unit. The booster unit modulates an input power and converts the input power into a boosted power. The boost control circuit is coupled to the frequency-changing voltage regulation circuit of the present invention. The frequency-changing voltage regulation circuit comprises: a voltage detection circuit and a frequency setting circuit. The voltage detection circuit detects the input power sent to the booster unit and generates an input level signal according to the value of the input power. The frequency setting circuit generates a reference frequency signal corresponding to the input level signal and uses the reference frequency signal to modulate the frequency that the booster unit performs power conversion.

Abstract:
A double-acting device for generating a synthetic jet is provided. The double-acting device includes a chamber having a cavity for a working fluid, a separating element for dividing the chamber into at least two sub-chambers, a control system connected to the chamber for controlling the separating element to act reciprocatingly, an input system connected to the chamber for inputting the working fluid to the chamber therethrough and an output system connected to the chamber for outputting the working fluid from the chamber therethrough. When the working fluid is pushed and pulled by a reciprocating action of the separating element, a train of vortices would be puffed and a non-zero-net-mass-flux fluid is generated through a designed structure and a defined arrangement of the input system and the output system.
Abstract:
A high-precision vortex flow meter includes a blunt body having a predetermined dimension and being arranged inside a fluid channel to serve as a vortex shedder. The vortex flow meter also includes a temperature detecting device for detecting the vortex shedder temperature and a temperature control element for adjusting the vortex shedder temperature. A frequency measuring device is arranged in the downstream section of the blunt body for detecting the vortex shedding frequency. From the measured temperatures of the upstream fluid flow and that of the blunt body, an effective temperature and a temperature ratio are calculated. The kinematic viscosity of the fluid is looked up from database. By using the relationship between the Strouhal number and Reynolds number, the fluid flow rate is calculated. By employing different blunt body temperature, the measurement range of the flow meter can be broadly extended.
Abstract:
In a power circuit for reducing standby power consumption, a power supply is defined to include a primary power system and a stationary power system. The stationary power system outputs a stationary power after obtaining an input power. A control unit controls ON/OFF of the primary power system, obtains the stationary power as the required power, and receives a PS ON/OFF signal for triggering the control unit, so that the control unit controls the primary power system to supply a primary output power. The power supply includes a switch unit having two ends connected to a power circuit for outputting the stationary power and a virtual load respectively. The PS ON/OFF signal is provided for controlling the switch unit. If the switch unit does not receive the PS ON/OFF signal, it is OFF in a standby mode to avoid unnecessary power consumption of the virtual load.

Abstract:
A power supply with an integrated power system has a common transformer. After the power supply receives input power, the common transformer generates an induction power at the secondary side. The power supply further includes a standby power system receiving the induction power and outputting a standby power, an actuation switch with one end electrically bridging the common transformer and the standby power system, a primary power system connecting to the other end of the actuation switch, and a power management unit receives the standby power to be activated. The standby power system modulates and transforms the induction power to the standby power to start operation of the power management unit. Users can trigger the power management unit to output an enabling signal to conduct the actuation switch to be ON so that the primary power system can receive the induction power and transform to output the primary output power.
Abstract:
A communication device and a method for auto-locking an input interface thereof are provided. In the present invention, an external volume received by the communication device having the input interface is determined when the communication device enters a communication mode. Thereafter, the external volume is compared to a predetermined volume. An input function of the input interface is disabled if the external volume exceeds the predetermined volume. As a result, activation of other functions due to unintended touch of the input interface during a phone call can be avoided.
