Publication number: 20240103640Abstract: 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.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Michelle R. Goldberg, Kathleen A. Bergeron, Paul X. Wang, Alex J. Lehmann, William P. Yarak, III, Kevin C. Armendariz, Zheng Gao

Touch-sensitive mechanical keyboard with sensing circuits for touch events and key depression events
Patent number: 11177093Abstract: 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.Type: GrantFiled: October 16, 2019Date of Patent: November 16, 2021Assignee: Apple Inc.Inventors: Karan Jain, William P.

Patent number: 10082880Abstract: A keyboard device includes a shell having a set of aperture formed into a top surface. A group of keys are disposed in the set of apertures. A platform is disposed under the group of keys and substantially fills an interior of the shell. The platform has a cavity formed in a lower surface of the platform. A circuit board, which is operable to control the keyboard is disposed within the cavity. The platform is configured to prevent ingress of liquid and debris that may enter the set of apertures. In some cases, the shell may have a rear aperture formed into a side wall, which may be configured as an antenna that is tuned to transmit a wireless signals at a transmission frequency.Type: GrantFiled: August 28, 2014Date of Patent: September 25, 2018Assignee: APPLE INC.Inventors: William P.
