  • Patent number: 11372609
    Abstract: A method provides pre-rendered information messages for display by a peripheral display unit connected to a base station over a data link. The method involves detecting that a data connection between the base station and the peripheral display unit is available, sending pre-rendered information messages from the base station to the peripheral display unit, and storing the pre-rendered information messages at the peripheral display unit for display in response to a status detected at the peripheral display unit. The base station may perform the pre-rendering of information messages in response to variation in configuration information relating to the peripheral display unit. The pre-rendered information messages may be paired with peripheral display unit statuses and the peripheral display unit may be configured so that, in the event that a particular status is detected, the corresponding pre-rendered information message is displayed without requiring data transmission from the base station.

  • Patent number: 11327571
    Abstract: The present disclosure generally relates to a new computer input and tracking device, and method of using, more particularly, a new type of digital pen which tracks user hand movements to generate series of point coordinates that represent a drawing or hand writing. Unlike prior digital pens such as the Apple Pencil™ or the Microsoft Surface Pen™, the new system does not require users to write on a touch-sensitive surface. Users can write on any surface such as a notebook, a table, a board, or even in mid air. Users can draw two-dimensional or three-dimensional drawings. The new method utilizes a pen marked with one or more groups of distinct tracking marks or tracking patterns and a camera to track the pen in real-time. A computer running a 3D algorithm processes the camera images, detects and distinguishes the tracking marks, and uses the tracking marks to calculate the positions of the tip of the pen in three-dimensional space.
