    Abstract: This disclosure relates to touch-sensitive mechanical keyboards and methods for detecting touch events and key depression events on the touch-sensitive mechanical keyboard. The keypad can include a plurality of domes, a plurality of key make electrodes, first touch electrodes, and second touch electrodes. The first touch electrodes may be located underneath the plurality of key make electrodes, and the second touch electrodes may not. Both touch electrodes can detect touch events based on self-capacitance sensing. A key depression event can cause the key make electrode to make electrical contact with a corresponding first touch electrode, creating a short circuit that may cause the measured signal to saturate. The keyboard can include a plurality of sensing circuits coupled to the key make electrodes, the first touch electrodes, and the second touch electrodes. The plurality of sensing circuits can be used to detect both touch events and key depression events.

    Abstract: This application relates to illuminated dome switches and a dome switch assembly having a first contact carried by a switch base and a dome shaped structure coupled to and supported by the switch base, the dome shaped structure comprising a material that is flexible and capable of internally transmitting visible light. The switch assembly can include a second contact coupled to the dome shaped structure and arranged opposite the first contact, and a light source configured to emit visible light, the light source in optical communication with the dome shaped structure such that at least some of the visible light emitted by the light source passes into the material and is subsequently emitted by the material in a generally uniform manner.

    Abstract: Connectors that may provide illumination at an opening in order to facilitate the mating to a corresponding connector by a user. The illumination may be generated on a tongue of a connector insert or in a connector receptacle. For connector receptacles, illumination may be guided to illuminate an opening of the connector receptacle, it may be guided out of a front edge of a tongue in the connector receptacle, or it may be guided in other directions. For connector inserts, illumination may be out of a front edge or sides of a tongue in the connector insert, or it may be guided in other directions. The illumination may be colored or patterned to convey information to a user. Other examples may include a connector system having a connector insert with a light guide to provide illumination from a connector receptacle to an opening in the connector insert where it may be viewed by a user. In other examples, other types of data, such as authentication or identification data, may be optically transmitted either to or through a connector insert inserted in the connector receptacle.

    Abstract: Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.

    Abstract: Embodiments are directed to a keyboard or other input structure having a diaphragm that controls the illumination of a perimeter of a keycap. In one aspect, the keyboard includes a dome configured to buckle in response to a depression of a keycap. A support structure may support the keycap above the dome. A light source may be positioned below the keycap and configured to illuminate one or more illuminable symbols defined on a top surface. A diaphragm may be positioned above the light source and have a barrier portion extending from a perimeter of the keycap. The barrier portion may be configured to control illumination of the perimeter of the light source, including substantially preventing the illumination of the perimeter in order to mask or conceal an illuminated halo around the keycap.

    Abstract: Embodiments are directed to a backlight integrated membrane for a keyboard. In one aspect, an embodiment includes a keyboard having a key cap. A feature plate may be positioned below the key cap and a membrane may be positioned below the feature plate. The membrane may include a transparent substrate optically coupled to a light emitting element. The membrane may also include electrical traces for a key switch disposed on the transparent substrate. The embodiment may further include a domed structure positioned on the membrane and configured to actuate the key switch when depressed.

    Abstract: Connector receptacles may be provided, where a multiple of such connector receptacles may be readily aligned to openings in a device enclosure, particularly where the openings are located on a curved or otherwise non-planar surface of the device enclosure. One example may provide a connector assembly that includes a plurality of connector receptacles. The connector receptacles in a connector assembly may be accurately aligned or registered to each other, and the connector assembly may be accurately aligned to a device enclosure. In this way, several connector receptacles may be accurately aligned to openings in the device enclosure. In another example, two or more connector receptacles may have faces that are at an oblique angle relative to each other.
