  • Patent number: 11086357
    Abstract: A dynamically flexible, attachable article, such as a wristband or an armband, includes a flexible electronic component coupled to a flexible support in a manner that is bendable or conformable to a user's wrist or other curved surface in a manner that makes the flexible electronic component easily viewable to the user. The attachable article also includes a connection mechanism disposed proximate to one or both of first and second ends of the attachable article to connect two different portions of the article together.

  • Patent number: 11079620
    Abstract: Techniques for optimizing the display area of an electronic display of an article include maximizing the contiguous area of the display, on one or more surfaces of the article, on which text or images may be presented to a user, and/or to minimize the area of a border of the display that is viewable to the user. Optimization techniques may include bending portions of the display, and/or minimizing the footprint of the display border by particularly configuring the electrical connections to the display elements. These optimization techniques may be applied to rigid electronic displays, to statically-flexed displays, or to dynamically flexible displays, as well as to other rigid, statically-flexed, or dynamically flexible electronic sheets of individual electronic elements, such as lighting arrays, solar cell arrays, sensor arrays, etc.

  • Patent number: 10834822
    Abstract: A dynamically flexible article or device, such as a wristband, an armband, a rollable e-reader, or a belt, includes a flexible electronic component (e.g., a flexible display) and a support structure coupled to the flexible electronic component. The support structure is configured to limit bending of the flexible electronic component to a range within a bending tolerance of the flexible electronic component.

  • Patent number: 10621956
    Abstract: An attachable article, such as a wristband, includes a flexible electronic display disposed thereon in a manner that is bendable or conformable to a user's wrist or other curved surface and that enables various images to be displayed on the electronic display in a manner that makes these images easily viewable to the user. The attachable article includes an adjustable band that can be fit to different sized wrists, for example, and includes a band orientation detection and calibration routine that enables messages or display screens to be placed at particular locations on the band with respect to a user's wrist. For example, the display orientation detection and calibration routine may be used to determine the portions or positions of the display that are at the top of the user's wrist and at the bottom of the user's wrist, and may thereafter calibrate the display to center display screens on the display at these particular locations.

  • Patent number: 10535325
    Abstract: A method for updating images displayed on an electronic display of a mobile device includes determining a time interval between successive updates of an image frame. The image frame is displayed on the electronic display, and the mobile device is configured to be in a low power mode between the successive updates. The method also includes receiving one or more application updates within the time interval after a first update of the image frame, and updating the image frame after the time interval based on the one or more application updates.
