  • Publication number: 20140295573
    Abstract: A biosensor with a dual gate structure is disclosed herein. The biosensor comprises: a transistor, a sensing pad, and a plurality of nanostructures. The sensing pad has a conductive area working as another gate and neighboring to the channel layer of the transistor, and a sensing area extended outward from the conductive area to be far away from the channel layer of the transistor, wherein the gate and the conductive area of the sensing pad are separated from each other by the channel layer. The plurality of nanostructures are utilized to bind a first protein to generate a drain current value, when the first protein is combined with the target protein and another drain current value is generated, whereby a variation between the two drain current values is calculated to obtain the concentration of the target protein in the protein solution.

  • Publication number: 20140083245
    Abstract: A harmonic reducer with clutch function includes a circular spline, a mounting base, a flexspline and a wave generator. When a power source drives the wave generator to rotate in a first direction, a one-way clutch engages to lock the mounting base so as to deform the flexspline and hence rotate the circular spline in the first direction. When an external force is applied to the output shaft in the first direction, the mounting base is driven by the flexspline so the one-way clutch disposed thereon is disengaged by a force in a second direction. At this moment, the rotation speed of the wave generator is equal to zero relative to the flexspline, so the wave generator can be driven by the circular spline to rotate along with the flexspline, and the central axel of the wave generator can be driven to rotate as well.

  • Publication number: 20130333516
    Abstract: A flexspline structure of a harmonic reducer is disclosed, comprising a circular spline, a flexspline and a wave generator. The flexspline is manufactured from tubular material into a thin-walled cylinder with external gear and is assembled with the circular spline. The wave generator is assembled with the flexspline and a power source, so the flexspline deforms and engages with the circular spline partially. The flexspline is fixed while the circular spline is connected to an output shaft. When the power source drives the wave generator to rotate, the flexspline also drives the circular spline and the output shaft to rotate simultaneously. The flexspline in the disclosure is manufactured directly from tubular material to eliminate the forging process in the conventional flexspline processing, so the material wear is reduced and processing time of lathing and gear hobbing are decreased noticeably as well.

  • Publication number: 20130333505
    Abstract: A harmonic reducer with a stationary gear includes a stationary gear, a circular spline, a flexspline and a wave generator. The wave generator is assembled with the flexspline and a power source, and then the flexspline is assembled with the stationary gear and the circular spline. The flexspline is deformed when assembled, so the external gear thereof partially engages the first internal gear of the stationary gear and the second internal gear of the circular spline. The stationary gear is fixed, so when the power source drives the wave generator to rotate, the flexspline deforms but does not rotate in relative to the stationary gear. In relative to the circular spline, the flexspline both deforms and rotates relatively, so the circular spline and the output shaft rotate in a reducing speed simultaneously.

  • Publication number: 20130333515
    Abstract: A flexspline mounting structure of a harmonic reducer includes a circular spline, a flexspline and a wave generator. The flexspline is fixed and mounted to a mounting base with a plurality of elastic walls, and then the mounting base is mounted to the casing of the reducer. The circular spline is connected to an output shaft, so when the power source drives the wave generator to rotate, the flexspline also drives the circular spline and the output shaft to rotate simultaneously. By mounting the flexspline on the flexible elastic walls of the mounting base, the present invention can overcome the drawback of the uneven internal stress of the flesxspline during deformation, so the rupture of the flexspline can be reduced and the life thereof can be prolonged.

  • Publication number: 20110057605
    Abstract: This invention discloses a power supply system and power supply method with a power saving function for a rechargeable battery. The power supply system includes a power adapter and a portable electronic device body. The power adapter has a control pin. The portable electronic device body includes a connector, a charging unit, and an embedded controller. The embedded controller is used for detecting a capacity state of the rechargeable battery and whether the rechargeable battery is connected with the connector to determine whether the rechargeable battery needs to be charged. When the rechargeable battery does not need to be charged, the embedded controller controls the power adapter to output a first voltage via the control pin. When the rechargeable battery needs to be charged, the embedded controller controls the power adapter to output a second voltage via the control pin. The first voltage is lower than the second voltage.
