  • Patent number: 11663462
    Abstract: A machine learning method and a machine learning device are provided. The machine learning method includes: receiving an input signal and performing normalization on the input signal; transmitting the normalized input signal to a convolutional layer; and adding a sparse coding layer after the convolutional layer, wherein the sparse coding layer uses dictionary atoms to reconstruct signals on a projection of the normalized input signal passing through the convolutional layer, and the sparse coding layer receives a mini-batch input to refresh the dictionary atoms.
    Type: Grant

  • Patent number: 7016283
    Abstract: A spindle motor inclination angle adjusting mechanism for an optical disk device includes two adjusting mechanisms to provide two rotational freedom for the base dock of the spindle motor to adjust the inclination angle of the spindle motor. The first adjusting mechanism has three support points that are not on the same straight line to support the base dock. Two of the support points are fixed and the third support point is movable relative to the other two support points to change the inclination angle of the base dock of the spindle motor. The second adjusting mechanism is a rotary element for carrying the first adjusting mechanism and driving the first adjusting mechanism to rotate and change the direction of the inclination angle of the base dock to adjust the spindle motor inclination angle.

  • Publication number: 20050011709
    Abstract: A dynamic vibration reduction system, applicable in an electronic product, includes a main buffering unit, an auxiliary buffering unit, and a driving module. The main buffering unit is connected to a carrier of the electronic product to reduce vibrations of the carrier. The auxiliary buffering unit is movably mounted on one side of the carrier. The driving module is assembled in the auxiliary buffering unit to either abut the auxiliary buffering unit against the carrier and reduce the vibration of the carrier, or space the auxiliary buffering unit away from the carrier at a predetermined distance. The vibration reduction of a system is variable with the control of the connection between the auxiliary buffering unit and the carrier to maximize the performance of the electronic product.

  • Patent number: 6363048
    Abstract: A disc clamp mechanism for preventing a disc (e.g., DVD-ROM or CD-ROM) from slipping and/or loosening in a high speed rotation comprises a positioning member sized to the center hole of the disc having a hole for being mounted on a turntable, and an inclined surface; a helical spring within the positioning member; a disc-clamping member sized to the center hole of the compact disc having circumferential raised portions, recessed portions each extending from the raised portion, and flexible V-shaped members surrounded by two recessed portions and a raised portion; and an elastic plane-like member mounted on the positioning member. As such, the disc is secured by the raised portions, the inclined surface, and the turntable when loaded onto the disc-clamping member. This mechanism finds applications in the DVD-ROM or CD-ROM products. Further, a thinner construction, an easy assembly, and a high positioning precision are realized by this mechanism.
