  • Patent number: 11340719
    Abstract: A touchpad press device includes a support unit having two first sides interconnecting between two second sides, and first engaging members proximate to the second sides. A touch unit with a touch switch is disposed above the support unit, and a transmission unit is disposed between the support unit and the touch unit. The transmission unit includes peripheral plates, each of which is disposed above one of the second sides and has second engaging members, and a pressing plate to trigger the touch switch. When one of the peripheral plates is pressed downward through the touch unit, the other peripheral plate turns upward so that the second engaging members thereof engage the respective first engaging members to limit the other peripheral plate from moving further upward.

  • Patent number: 11009916
    Abstract: A touch input device includes a frame unit, a circuit unit and a touch pad. The circuit unit includes a circuit board, a dome-shaped actuating member including an actuating portion and a resilient metal sheet connected between the actuating portion and the circuit board, and a noise reduction member having a main body connected to the resilient metal sheet, made of an elastic material and formed with a recess surrounding the actuating portion. A touch surface of the touch pad is touchable to push the circuit unit toward the block member, such that the actuating portion contacts the block member to deform the resilient metal sheet to electrically connect the actuating portion with the circuit board.

  • Patent number: 10861659
    Abstract: A touch input device includes a base board, a circuit module having a free end portion and a connecting end portion, a metallic connecting member and an annular, metallic frame. The connecting member includes a positioning portion fixedly mounted to the connecting end portion of the circuit module, and an elastic arm extending from the positioning portion away from the connecting end portion and toward a free end portion in such a way to define a coupling groove that indents away therefrom. The frame is spaced apart from the circuit module and includes a coupling portion that is embossed from a side of the frame proximate to the connecting member, and that has a coupling block coupled to the coupling groove of the elastic arm.

  • Patent number: 9282243
    Abstract: The present invention is directed to an exposure parameter compensation method and an imaging device. A capture-mode image capturing step is performed to obtain a first image and a second image according to a first exposure time and a second exposure time respectively based on a first light sensitivity and a predetermined time. The first image and the second image are operated on to result in a difference image. The first light sensitivity is replaced with a second light sensitivity, which is then recorded.

  • Patent number: 8780261
    Abstract: The present invention is directed to a light sensitivity calibration method and an imaging device. An exposure step is performed to obtain a light sensitivity according to a predetermined time. A time adjustment step is performed to adjust the predetermined time according to the light sensitivity, thereby obtaining an adjusted time. The predetermined time is replaced with the adjusted time and the exposure and time adjustment steps are repeatedly performed, until the adjusted time converges within a predetermined range.
