  • Publication number: 20220300088
    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.

  • Publication number: 20220247571
    Abstract: A labeling method is provided. In the method, target image data of a target image is acquired from an offline storage device. The target image data is encrypted based on a first target account. A permission to load the target image data is verified based on a second target account logged in to a labeling client. The target image is loaded in the labeling client in response to the permission to load the target image being verified when the second target account logged in to the labeling client matches the first target account. A label for the target image is received. Further, the label for the target image is transmitted to a server. The server is configured to store the label in association with the target image. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

  • Patent number: 11360560
    Abstract: An input device, such as a stylus, can include a piezoelectric device for providing haptic feedback and/or detecting user input. The piezoelectric device can be coupled to an inner surface of a housing of the stylus. The piezoelectric device can provide haptic feedback with a force to the housing when an electric voltage is applied to the piezoelectric device. The haptic feedback can provide information to the user relating operation of the stylus with an external device. The piezoelectric device can also produce an electric voltage when an input force is applied to an outer surface of the housing and transmitted to the piezoelectric device. The electric voltage can be used to detect tactile input from a user.

  • Publication number: 20220164036
    Abstract: A keyboard may be provided that has keys overlapped by a touch sensor. The keyboard may have key sensor circuitry for monitoring switching in the keys for key press input. The keyboard may also have touch sensor circuitry such as capacitive touch sensor circuitry that monitors capacitive electrodes in the touch sensor for touch sensor input such as multitouch gesture input. The keyboard may include an outer layer of fabric that overlaps the keys. The fabric may have openings that are arranged to form alphanumeric characters. Light sources may emit light that passes through the openings and illuminates the alphanumeric characters. The touch sensor may have signal lines that are not visible through the openings. The signal lines may be transparent, may be covered by a diffuser, or may circumvent the openings so that they do not overlap.

  • Patent number: 11282659
    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.
