  • Patent number: 11997777
    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: 4991756
    Abstract: A device is taught for drying wet gloves or mittens or for drying portions of other wet clothing having inside openings therein which are substantially circular in cross-section and which are of a depth of at least about three inches. The device is a hollow cylindrical dryer or is slightly tapered from cylindrical to slightly conically shaped. The main portion of the dryer between its ends preferably consists of a grid of many square or diamond shaped ventilation holes to facilitate evaporation of moisture. The dryer can be made of flexible plastic material and molded into its final shape (and also into such a shape that a number of said dryers can be "nested" inside each other); or the dryer can be molded in an essentially planar condition and then forced by the user into its shape described above, by slight exertion of hand pressure.
