  • Publication number: 20240077968
    Abstract: An electronic device has sensors. More particularly, the electronic device is a small form factor electronic device such as earbuds, styluses, or electronic pencils, earphones, and so on. In some implementations, one or more touch sensors and one or more force sensors are coupled to a flexible circuit. In various implementations, the touch sensor and the force sensor are part of a single module controlled by a single controller. In a number of implementations, the flexible circuit is laminated to one or more portions of an interior surface of the electronic device.

  • Patent number: 11754779
    Abstract: An electronic device may have a display, a display cover layer, and an image transport layer formed from a coherent fiber bundle. The coherent fiber bundle may have an input surface that receives an image from the display and a corresponding output surface to which the image is provide through the coherent fiber bundle. The coherent fiber bundle may be placed between the display and the display cover layer and mounted to a housing. The coherent fiber bundle may have fiber cores with bends that help conceal the housing from view and make the display appear borderless. A central portion of the coherent fiber bundle may be formed from different materials and/or structures than a surrounding border portion of the layer.

  • Publication number: 20210089170
    Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

  • Publication number: 20090194408
    Abstract: The present invention provides a plasma method for conversion of carbon dioxide into useful organic products. In this method, carbon dioxide and counterpart molecules are mixed in a reaction chamber and the plasma excitation is utilized to trigger chemical reactions. Depending on the magnitude of the input power and molecular structures of counterparts, the final product may be polymers, oligomers, or low molecular weight small molecules. The conversion yields of carbon dioxide and chemical structures of the resulting products are strongly dependent on the selection of the counterpart molecules. Through this plasma technology, carbon dioxide is converted into useful materials such as plastics or fuels. This method is not only used to remedy global warming but also to produce new materials and energy.
