  • Patent number: 11842003
    Abstract: A touch panel device includes a face plate, a bracket, and a PCB. The face plate receives a contact. The bracket includes a permanent magnet affixed to a surface of the bracket. The PCB is positioned proximate to the bracket such that a surface of the PCB is adjacent to the bracket. The PCB includes a Hall sensor collocated proximate to the permanent magnet. The touch panel circuit is coupled to the Hall sensor. When the contact is received at the face plate, the PCB moves closer to the bracket. In response, the touch panel circuit receives a voltage from the Hall sensor, determines a force associated with the contact based upon the voltage, and triggers a haptic feedback response in the bracket.

  • Publication number: 20210341969
    Abstract: A curved display integrates in a portable information handling system housing to present visual images to an end user about an arc for improved viewing angle. The portable information handling system rotates the housing from an open position that exposes the display in a curved configuration to a closed position that brings the display against a main housing portion with the display transitioned from the curved to a planar configuration for a low profile storage position. Display curve is managed with a curved support frame that bends to a planar form, a pair of perpendicular-axis hinges that rotate opposing housings about a horizontal axis and manage display curve about a vertical axis, and a dual axis hinge with a sliding bracket that adjusts for greater housing spacing in the curved configuration.

  • Patent number: 11086221
    Abstract: A first photoresist pattern and a second photoresist pattern are formed over a substrate. The first photoresist pattern is separated from the second photoresist pattern by a gap. A chemical mixture is coated on the first and second photoresist patterns. The chemical mixture contains a chemical material and surfactant particles mixed into the chemical material. The chemical mixture fills the gap. A baking process is performed on the first and second photoresist patterns, the baking process causing the gap to shrink. At least some surfactant particles are disposed at sidewall boundaries of the gap. A developing process is performed on the first and second photoresist patterns. The developing process removes the chemical mixture in the gap and over the photoresist patterns. The surfactant particles disposed at sidewall boundaries of the gap reduce a capillary effect during the developing process.
