    摘要: The present invention is gallium nitride based operational amplifier because reliability and performance of the gallium nitride is better than the silicon counterpart in radiation environment. The operational amplifier includes four stages, first stage is dual input balanced output differential amplifier, second stage is dual input unbalanced differential amplifier, third stage is buffer stage to couple second and fourth stage, and fourth stage is cascaded common source amplifier with degeneration. A capacitor coupled between second and third stage is to enhance the stability of operational amplifier.

    摘要: A center of pressure (CoP) based control system includes a sensing device and an electronic device connected to the sensing device. The sensing device includes sensors each of which continuously measures force exerted thereon by a subject and generates a sense signal based on a result of the measurement. The electronic device is connected to the sensing device, and receives the sense signals from the respective sensors, generates CoP data associated with a CoP trajectory based on the sense signals, determines whether a turning point exists in the CoP trajectory, generates an indication signal based on a result of the determination, and generates a control signal based on a direction of one of displacements of the CoP.

    摘要: A method for performing contactless ODEP for separation of CTCs is provided with the steps of obtaining patients' blood with rare cell suspected CTCs; adding at least one fluorescent antibody binding to CTCs into the blood; staining the blood; injecting the stained blood with fluorescent dye into an ODEP device and then performing fluorescent image identification; trapping the CTCs with at least one fluorescent antibody in the ODEP device by creating an image pattern and then generating an ODEP force; Separating the trapped CTCs from other non-CTCs cells; absorbing the trapped CTCs; and obtaining a high purity of CTCs. An apparatus for performing contactless ODEP for separation of CTCs is also provided.
