Abstract: A suction device and a suction force adjustment method thereof are provided. A detecting device collects sound generated when the suction device executes a suction operation to obtain characteristics of a sound signal. The detecting device determines a clogging degree of a filter disposed on an exhaust vent of a suction unit, an airflow velocity in a suction pipe, a material of the suctioned surface, and a degree of closure between a suction port of the suction device and the suctioned surface according to the characteristics of the sound signal. A control host adjusts a suction force of the suction unit or adjusts the degree of closure between the suction port of the suction device and the suctioned surface according to a detected result of the detecting device, and provides warning information for cleaning or replacing the filter.

Abstract: A suction device and a suction force adjustment method thereof are provided. An optical detection unit is disposed on a suction path of a suction pipe to detect an object flowing through the suction pipe. Physical features of the object are determined according to a sensing result of the optical detection unit. A suction force of a suction unit is regulated based on the physical features of the object.

Abstract: An optical detection device and a detection method thereof are provided. A linear light source provides a light curtain formed by multiple light beams, the light curtain is located on a transportation path of transporting an object to be detected. A sensor set senses the part of light beams not interrupted by the object to be detected, so as to generate a sensing signal with various strengths. A control circuit determines a physical characteristic, moving speed and position of the object to be detected according to the strength of the sensing signal.

Abstract: An exemplary embodiment of the present disclosure illustrates a clock rate control method. Firstly, a usage of a first input first output (FIFO) buffer in an electronic device is detected. Then, whether the usage falls within a first specific interval is determined, wherein the first specific interval has a first upper limit value and a first lower limit value. When the usage is larger than the first upper limit value, a clock rate of the inner device of the electronic device is increased; when the usage is less than the first lower limit value, the clock rate is decreased.

Abstract: A virtual signal source generating apparatus is provided. The virtual signal source generating apparatus includes at least an audio interface, a control module, a detecting module and a processing module. The control module is used for acquiring an audio signal from a signal source, wherein the audio signal includes a clock information and an audio information. The detecting module is used for detecting whether the audio interface is coupled to the signal source. The processing module is used for transmitting the audio signal. If the detecting module detects that the signal source disappears when the virtual signal source generating apparatus is in the recording mode, the control module transmits a control signal to the processing module so that the processing module transmits a virtual audio signal to a host.

Abstract: An audio signal transmission apparatus avoiding noise generation is applied to a game platform functions by executing a recording process, and comprises: an analog-to-digital converter, an intermediary processing unit, a counter, and a controlling unit. The analog-to-digital converter is used for converting an analog audio signal to a first digital audio signal. The intermediary processing unit is connected with the analog-to-digital converter for transmitting the first digital audio signal. The counter controls the intermediary processing unit to output the first digital audio signal after counting a specific time. The controlling unit, connected with the counter and the intermediary processing unit, is used for transmitting the first digital audio signal to the game platform. Therefore, the present invention can achieve the purpose for avoiding noise generation when the audio signal transmission apparatus plugs into the game platform.
