  • IMAGING OPTICAL LENS ASSEMBLY, IMAGE CAPTURING UNIT AND ELECTRONIC DEVICE
    Publication number: 20240134155
    Abstract: An imaging optical lens assembly includes four lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element and a fourth lens element. Each of the four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one of all lens surfaces of the four lens elements is aspheric and has at least one inflection point.

  • Elimination of environmental interference to a capacitive touch pad by a dummy trace
    Patent number: 8823680
    Abstract: A capacitive touch pad includes a sensor layer for sensing a touch of an object and a dummy trace below the sensor layer. The dummy trace is sensed to obtain a sensed value while the dummy trace is shielded by the sensor layer from interference of the object such that the sensed value reflects only environmental variation. Therefore, environmental variation can be identified depending on the sensed value, and the sensor layer can be calibrated properly.

  • LINEARITY IMPROVEMENT OF A CAPACITIVE TOUCH PAD
    Publication number: 20120026130
    Abstract: A capacitive touchpad includes a first trace established by a string of first rhombic sensing cells successively in a first direction and a plurality of singular second rhombic sensing cells branched in a second direction from the string of first rhombic sensing cells, and a second trace established by a string of third rhombic sensing cells successively in the first direction and a plurality of singular fourth rhombic sensing cells branched in the second direction from the string of third rhombic sensing cells, and the second rhombic sensing cells are interleaved with the fourth rhombic sensing cells in the first direction. The capacitive touchpad is thus improved in its linearity.
