摘要： A fluid flow metering device and a method thereof are provided. The fluid flow metering device includes a fluid flow detector, a memory, a micro controller and a power generator. The fluid flow detector is disposed in a supply tube of a fluid flow provider. When the fluid flows in the supply tube, the power generator generates a supplying power through flow of the fluid, and provides the supplying power to the fluid flow detector, the memory and the micro controller. When the fluid flow detector detects the flow of the fluid, the fluid flow detector detects the flow of the fluid outputted from the supply tube to derive a detecting value. The micro controller receives the detecting value and writes the detecting value into the memory, or the micro controller converts the detecting value into a flow value and writes the flow value into the memory.

摘要： A management controller is coupled to a plurality of external devices. The management controller includes a control circuit and a transmission circuit. The control circuit generates a control signal according to a first counting value and a second counting value. The transmission circuit is coupled to the external devices. In response to the first counting value not being equal to a first target value, the transmission circuit enters a circulating mode according to the control signal. In the circulating mode, the transmission circuit triggers the external devices in order. In response to the second counting value not being equal to a second target value, the transmission circuit continues to operate in the circulating mode. In response to the second counting value being equal to the second target value, the transmission circuit exits the circulating mode.

摘要： A detection circuit for detecting a clock signal includes a multiplexer, a digital-to-analog converter, a comparator, and a counter. The multiplexer outputs either a first signal or a second signal as a selection signal. The digital-to-analog converter outputs a reference voltage according to the selection signal. The comparator compares the clock signal to the reference voltage to generate a comparison signal. The counter counts a reference clock signal to generate an overflow signal, and resets the overflow signal according to the comparison signal. The overflow signal indicates the amplitude of the clock signal.

摘要： A programmable serial input-output controller is provided. A timer circuit performs a timing operation. An input pin is configured to receive an input signal from an external circuit. An output pin is configured to provide an output signal to the external circuit. In an output mode, the sequence controller provides an initial level to the output pin and controls the timer circuit to perform the timing operation. In response to a duration of the timer circuit performing the timing operation reaching first transmission time, the sequence controller inverts the level of the output pin and controls the timer circuit to re-perform the timing operation. In response to the duration of the timer circuit re-performing the timing operation reaching second transmission time, the sequence controller inverts the level of the output pin.

摘要： A control device for adjusting the output voltage of a voltage generator, wherein the control device includes a master circuit, a slave circuit, and a power-scaling control circuit, is provided. The master circuit is coupled to a system bus. The slave circuit is coupled to the system bus. The power-scaling control circuit is coupled between the master circuit and the slave circuit. In response to the master circuit sending a voltage-scaling command, the power-scaling control circuit sets a control signal at a suspension level so that the slave circuit sets a specific signal transmitted by the system bus at a wait level. In response to the specific signal being at the wait level, the master circuit stops accessing the first specific device of the slave circuit. In response to the control signal being at the suspension level, the power-scaling control circuit adjusts the output voltage.

摘要： A control device is used to adjust an output voltage of a voltage generator, and includes a master circuit, a slave circuit, and a power-scaling control circuit. The master circuit is coupled to a first bus. The slave circuit is coupled to a second bus. In a normal mode, the first and second buses are connected to each other via the power-scaling control circuit, the master circuit accesses the slave circuit via the first and second buses. In an adjustment mode, the power-scaling control circuit controls the master circuit to stop accessing the slave circuit, and the power-scaling control circuit adjusts the output voltage. When the master circuit sends a trigger signal, the power-scaling control circuit enters the adjustment mode. When the master circuit does not send the trigger signal, the power-scaling control circuit enters the normal mode.
