Abstract: A cell activation reactor and a cell activation method are provided. The cell activation reactor includes a body, a rotating part, an upper cover, a microporous film, and multiple baffles. The body has an accommodating space, which is suitable for accommodating multiple cells and multiple magnetic beads. The rotating part is disposed in the accommodating space and includes multiple impellers. The microporous film is disposed in the accommodating space and covers multiple holes of the accommodating space. The baffles are disposed in the body. When the rotating part is driven to rotate, the interaction between the baffles and the impellers separates the cells and the magnetic beads.

Abstract: A charger calibrating device and a calibrating method thereof. The device comprises a control module and a processing module. The control module controls a charger to be calibrated to perform a first stage charging and a second stage charging on an electronic device. The processing module performs an adjusting process according to the second stage charging time for adjusting the high level period of the PWM signal in the charging circuit of the charger. In the adjusting process, generating an updated high level period by adding or decreasing a preset adjusting amplitude, and decrease the preset adjusting amplitude by half to generate an updated adjusting amplitude. The processing module terminates the calibrating process after repeating the aforementioned calibrating loop a preset number of times.

Abstract: A flash charging protection circuit and a control method thereof adapted to a charging circuit coupled to a power supply are provided. An analog-to-digital converter receives a feedback voltage output from the charging circuit and an input voltage output from the power supply. A power voltage detection module detects whether the input voltage is abnormal or not. A charging state detection module detects whether a rising curve of the feedback voltage is abnormal or not. If a controller receives a power abnormal signal or a charging state abnormal signal, the controller disables a pulse width modulation signal generator to produce a pulse width modulation signal.
