  • Publication number: 20220095443
    Abstract: An electrostatic discharge (ESD) robust design for an input device such as a stylus is disclosed. The input device can include one or more components, such as one or more Schottky diodes, that can be damaged by ESD events. To reduce the likelihood of damage to sensitive components, the parasitic capacitance between sensitive conductive paths and reference ground paths of the input device that could otherwise provide electrostatic discharge paths can be reduced (arranging current limiting resistance at specific locations among sensitive components, creating physical separation between sensitive conductive paths and reference ground paths), shielding can be added to shield the sensitive electronics from ESD pulses, and high dielectric breakdown material can be added to prevent ESD pulse entry or exit of not otherwise protected circuit parts.

  • Patent number: 9968004
    Abstract: According to various aspects, exemplary embodiments are disclosed of thermal interface materials including electrically-conductive material, shields including thermal interface materials, and related methods. In an exemplary embodiment, a thermal interface material generally includes a top surface, a bottom surface, and one or more outer side surfaces extending between the top and bottom surfaces.

The thermal interface material may be configured to be operable as a waveguide through which energy below a cutoff frequency cannot flow. The electrically-conductive material may be parallel with a direction of heat flow from a heat source to a heat removal/dissipation structure when the bottom surface is positioned against or adjacent the heat source and the top surface is positioned adjacent or against the heat removal/dissipation structure.
