  • Patent number: 11789757
    Abstract: Methods, systems, graphical user interfaces (GUIs), and computer-readable media for presenting GUI elements generated based on information associated with an event are generally described. An event information presentation system may be configured to present GUI elements generated based on substantially real-time event information associated with a live event, such as a sporting event. Illustrative event information may include object movement and location information for objects such as event participants (for instance, players) and articles (for instance, a football for a football game event). The event information may be interpreted based on activity categories to automatically differentiate, organize, highlight, or the like the event information in order to generate relevant and meaningful GUI elements.

    Abstract: A method of designing an outdoor playground complex is disclosed. Complex components are represented by reduced scale, two-dimensional projections of interchangeable playground devices. The projections are formed into pliable, transparent templates consisting of an electro-static vinyl material. The significant features viewable in each projection are lined on the templates. The components are stored on pliable sheets which releaseably adhere to the templates. The complex itself is designed by selecting possible components, removing the same from the storage sheet and placing the selected templates adjacent to each other on a transparent work surface which is adapted to releaseably adhere to the template.The combination of transparent, lined templates and transparent work surface allows easy photocopying of the selected design with all significant features clearly set forth. The transparent work surface allows the design to be laid over scale drawings of play areas if desired.

The device includes a disk-like, double sided chalkboard member and a ring-like frame member extending completely about the periphery of the blackboard member with the blackboard member rotatably mounted to the frame member. Alphabetic letters and the like are located about the frame member on one side thereof. Numerals and the like may be located about the other side of the frame member with the numerals arranged similar to a clock face. Pointers are attached to both sides of the chalkboard member whereby rotation of the chalkboard member will cause the pointers to point towards various specific letters and/or numbers and/or the like, etc. Indicia-bearing inserts are rotatably attached to the front and back surfaces of the frame.
