Abstract: A connector system having a pair of connector components capable of being used as a reuseable aseptic connection in bioprocessing and/or cell manufacturing processes. Each connector component includes a connector housing having a mating surface with an opening and a door moveable to close and open the opening, and a connector assembly therein. The connector assembly includes a base member having a fluid port; an engagement piece having a pusher portion; and a valve unit therebetween, the valve unit having a resilient deformable valve member. The pusher portion is moveable to cause the pusher portion to urge open the resilient deformable valve member for enabling the fluid flow. When the pair of connector components are interlocked, the doors open and the connector assemblies move and engage with each other through the openings causing the resilient deformable valve members to open for establishing a fluid connection.

Abstract: A method and a system for analyzing music rhythm in real time are provided. In the method, a device receives audio via an input interface. The audio is decoded by an audio-processing circuit to extract frame information. A hop size is obtained according to a frame size and an overlapped frame size set, and a frame rate is calculated according to the sampling rate and the hop size. An initial value of a beat period can be calculated according to the sampling rate and an initial BPM value. A beat location can be obtained based on a quantity of sampling points in a beat. The system uses a recursive algorithm to speculate a next beat location. A new beat period is recalculated according to the frame information of the audio in a past period of time. The next beat location is obtained and added with a beat-prompting note.

Abstract: A player device includes a multi-media receiving device and a signal processing device. The signal processing device performs a mixing operation to mix a multi-media signal and a pseudo stereo signal to generate a mixed multi-media signal. The signal processing device further converts a system sound from a mono sound signal into the pseudo stereo signal by selecting at least one frequency component of the system sound as a modulation signal and combining a delayed version of the modulation signal and remaining frequency components of the system sound to generate the pseudo stereo signal. In the mixing operation, the signal processing device combines a multi-media sound component of a first channel and a system sound component of the first channel and combines a multi-media sound component of a second channel and a system sound component of the second channel to generate the mixed multimedia signal.
