A handheld electronic device may include a portable housing and a shielding container within the portable housing. The shielding container may include a shielding frame and a shielding lid carried thereby. A printed circuit board may be within the shielding container. The shielding frame may include a planar base with at least one opening therein, a pair of opposing side walls integrally formed with the base and extending upwardly therefrom, and a pair of opposing end walls integrally formed with the base and extending upwardly therefrom. Also, the shielding frame may include at least one intermediate partition wall integrally formed with the base and extending upwardly therefrom to define a plurality of container compartments. The partition wall may also extend only partway between the opposing side walls to define at least one partition end gap therewith.

Handheld electronic device including multi-compartment shielding container and associated methods

An improved method of employing a switch assembly for use in providing input to a handheld electronic device comprises employing a capacitive sensing system having a capacitive slider input device that detects navigational inputs. The switch assembly further provides a pair of switches mounted to the slider on an underside thereof to provide selection or escape inputs as desired.

Switch assembly and associated handheld electronic device

An apparatus for providing electrostatic discharge protection includes a plurality of conductive circumferential extensions defined by overlapping circular voids between a first conductor surface and a second conductor surface.

Spark gap apparatus and method for electrostatic discharge protection

An apparatus for providing electrostatic discharge protection includes a first conductive trace and a second conductive trace. The first conductive trace defines a first conductive periphery and is deposited on a first surface. The second conductive trace defines a second conductive periphery and is deposited on a second surface. The second surface is spaced apart from the first surface by a gap distance and in parallel relation so that a spark gap is defined by the gap distance between the first conductive periphery and the second conductive periphery.
