Abstract: Embodiments are directed to a low profile key for a keyboard having an overmolded support structure. In one aspect, an embodiment includes a key cap having an illuminable symbol. A support structure having a pair of overmolded wings may pivotally couple to the key cap. A switch housing may surround the support structure and connect each of the first and second wings. A tactile dome may be at least partially positioned within the switch housing and configured to bias the key cap upward. A sensing membrane may be positioned along an underside surface of the tactile dome and configured to trigger a switch event in response to a collapsing of the tactile dome caused by a depression of the key cap. A feature plate may be positioned below the sensing membrane. A light guide panel may define at least one light extraction feature that may be configured to propagate light toward the key cap and cause illumination of the illuminable symbol.

Abstract: A ring electrode to determine the orientation of the stylus relative to the surface. The stylus can include a ring electrode configuration which can improve capacitive coupling between the ring electrode and the touch panel. The ring electrode configuration can include a ring electrode and ground ring, and ground plate. By varying the lengths of ring electrode, ground ring, ground plate, and the distance between these elements, the electric field emanating from the ring electrode can be tuned to optimize the capacitive coupling between the ring electrode and surface. In some examples, the ring electrode can include multiple sub-rings. In some examples, the ring electrode can comprise a crown shape including projections, each having a width that tapers to a minimum width along the length of the ring electrode.

Abstract: An electronic device may have printed circuits to which electrical components are mounted. Plastic may be molded over a printed circuit. Vias may be formed in the printed circuit that connect metal traces on the surface of the molded plastic to metal traces on the printed circuit. The vias may be formed by drilling or by covering the metal traces on the printed circuit with mold pins in a molding tool during plastic molding operations. Plated metal traces or other metal traces may extend onto the interior surface of via holes. Vias may also be filled with conductive material such as solder or conductive adhesive. Metal members that are soldered or otherwise connected to printed circuit traces may be used in coupling surface metal traces to printed circuit traces. Antenna structure, shielding structures, and electrodes for a stylus may be formed using the metal traces on the molded plastic.
