  • Patent number: 11955495
    Abstract: The present disclosure provides an image sensing module including a main board and an image sensor. The main board has a first surface and a second surface opposite to each other. The image sensor is disposed on the first surface of the main board and includes a plurality of isolation structures and a photoelectric conversion element between the plurality of isolation structures. A first angle is provided between a light incident surface of the photoelectric conversion element and the first surface of the main board, and a second angle is provided between a light beam incident to the light incident surface of the photoelectric conversion element and a normal vector of the light incident surface. The second angle is about equal to the Brewster angle at the interface of the light beam incident to the light incident surface.

  • Patent number: 11934107
    Abstract: Embodiments described herein relate to methods of forming layers using maskless based lithography. In these embodiments, the methods implement ladders of dose change such that a geometric shape can be divided into overlaying sections. The overlaying sections can include a different dose of each section such that taper control can be achieved. The taper can be achieved by manipulating the geometry “mask data” into overlaying sections that are exposed by various doses controlled by pixel blending (PB) exposure techniques. To perform the methods described herein, a maskless lithography tool is used. The maskless lithography tool includes a controller that performs software based “mask data” manipulation.

  • Publication number: 20240086014
    Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

  • Publication number: 20110259028
    Abstract: A temperature regulating device includes a C-shape portion, at least a solar panel and a small fan. A space is provided in the C-shape portion. Several outlets are disposed on top of the C-shape portion. Several inlets are disposed on the bottom of the C-shape portion and are in fluid communication with the space. The solar panel is disposed on the outer side of the C-shape portion to absorb sunlight so as to convert it to electricity. The small fan is electrically connected with the solar panel and is disposed in a space of the C-shape portion. Therefore, a user may wear the device and uses the solar panel to generate electricity. The device is easy to carry and use and is environmentally friendly.
