  • Patent number: 11452435
    Abstract: A deflection device of steerable endoscope includes a first base, a second base, elastic reposition members and tendon wires. The second base is located above the first base along the endoscope center axis. The elastic reposition members are inlaid between the first and the second bases. Each elastic reposition member includes a first plate connecting to the first base, a second plate connecting to the second base, and a waveform bar connecting the first and the second plates. The wave-height of the waveform bar is not parallel to the endoscope center axis. The tendon wires are located on the two opposite sides of each elastic reposition member. The tendon wires are parallel to and distant from the endoscope center axis. Bending of the steerable endoscope is precisely controlled, and structure of the deflection device is simplified in the invention.

  • Patent number: 10863065
    Abstract: A camera module includes a holder frame, a first lens unit, a second lens unit, a first image-sensing unit and a second image-sensing unit. The holder frame includes a first fixed portion and a second fixed portion. The first lens unit is disposed through the first fixed portion and has a first light incident end and a first light exit end. The second lens unit is disposed through the second fixed portion and has a second light incident end and a second light exit end. The first image-sensing unit is disposed opposite to the first light exit end of the first lens unit. The second image-sensing unit is disposed opposite to the second light exit end of the second lens unit. In addition, a manufacturing method of a camera module is also disclosed.

  • Patent number: 10842354
    Abstract: An endoscope device comprises an image capturing unit, a supporting unit, a first and a second coaxial conductive units, and a conductive glue. The image capturing unit has a sensing surface and a back surface with at least two conductive pads thereon. The supporting unit has at least two carrying portions corresponding to the at least two conductive pads respectively. The supporting unit is connected with the back surface of the image capturing unit and extends along a direction approximately orthogonal to the back surface. The first and second coaxial conductive units are located at corresponding carrying portions respectively. The conductive glue covers the first coaxial conductive unit and the conductive pad corresponding to the first coaxial conductive unit, and covers the second coaxial conductive unit and the conductive pad corresponding to the second coaxial conductive unit.

  • Patent number: 10676147
    Abstract: A safety warning method includes the following steps. Step 1 is to generate a plurality of distance sensing signals by an optical object ranging module according to an approaching object. Step 2 is to obtain a relative distance trend according to the distance sensing signals and its corresponding time. Step 3 is to generate a control signal according to the relative distance trend. Step 4 is to drive and control a warning device to generate a warning signal according to the control signal. In addition, the present invention also provides a mobile vehicle and a safety warning device.

  • Patent number: 10468218
    Abstract: The present invention provides a relay with a shape memory alloy (SMA) wire driven mechanism. Conventional mechanical relays rely on electromagnetic principle to operate. Hence, magnetic fields of electromagnetic relays often interfere with magnetic fields of other electrical components, thus resulting in the components physically interfering with each other. The present invention utilizes the shape memory characteristics of a SMA wire to achieve the purpose of changing the operation of the relay. Specifically, when a SMA wire is heated, it restores to its original shape or original length. Comparing to conventional mechanical relays, the relay provided by the present invention does not magnetically interfere with other electrical components, and thus is able to function effectively. In addition, because the relay of the present invention does not require iron cores or coils, available space therein is increased and may be used to accommodate control circuits with various functions.

  • Patent number: 10241381
    Abstract: A mobile device with variable aperture function includes two driving members, which deformation and retraction can be controlled to cause movement of a light hole of a movable aperture sheet towards a camera lens, where the amount of light entering into the camera lens is determined by the light hole of the movable aperture sheet and when the light hole in the movable aperture sheet moves away from the camera lens, the amount of light entering into the camera lens is determined by the camera lens itself, thereby varying the amount of light entering into the camera lens and eliminating the fixed amount of light due to the fixed aperture of the prior art mobile device and permitting miniaturization of the present mobile device.
