An electronic device may have a display and other electrical components that are sensitive to electrostatic charge. A button may pass through an opening in a layer of the display. A metal trim may surround the button. The housing may have an opening with a clear lens surrounded by a metal trim. To prevent damage from electrostatic discharge, an electrostatic discharge path may be formed in the device that includes a metal trim surrounding a component such as a button member or camera lens, metal traces on the inner surface of a display layer or a housing, a grounded metal housing structure, and a spring or other conductive structure that couples the metal traces to the grounded metal housing structure. Displays may be provided with electrostatic discharge paths that route electrostatic charge to grounded metal housing structures.

Provided is a storage tank or structure with conductive fiber material (e.g. carbon fiber) for dissipating electrostatic charge. The tank comprises a tank wall made of composite material, such as polyester-fiberglass composite. On an inner tank surface, open areas are provided in which the conductive fiber is exposed. The conductive fiber material has broken fiber tips and stray fibers for collecting electrostatic charge. Outside the open areas, the conductive fiber material is covered with a layer of cured resin. The conductive fiber is exposed only in the open areas. An impermeable film may be present under the conductive fiber in the open areas. The present invention also includes a method for making the tank, in which a liquid, gel, or impermeable film mask is applied to the conductive fiber material. The mask functions to prevent infiltration of liquid resin into the conductive fiber material.
