Abstract: Systems and methods include a document serving circuit structured to access a document data, the document data comprising data for a unified document surface, and to provide at least a portion of the document data to a client serving circuit. The client serving circuit is structured to implement a unified document surface interface in response to the at least a portion of the document data, implement an extension creation interface, and to provide a pack implementation value to the document serving circuit in response to user interactions with the extension creation interface. The document serving circuit is further structured to determine a pack definition value in response to the pack implementation value.

Abstract: An example system may include a document snapshot circuit structured to generate a document snapshot configured to capture a state of a document at a time marker and a document sharding circuit structured to analyze the document snapshot, and generate a first plurality of shard documents capturing the state of the document at the time marker. The system may include a document serving circuit structured to access the first plurality of shard documents, and provide at least a subset of the first plurality of shard documents to a client serving circuit structured to implement a unified document surface interface in response to the at least a subset of the first plurality of shard documents. The document serving circuit is configured to provide the subset of the first plurality of shard documents in an order determined to prioritize shards related to a last accessed location of the document.

Abstract: Systems and methods for publication and external interfacing for a unified document surface are disclosed. An example system may include a document serving circuit structured to access a document data, the document data comprising data for a unified document surface, and provide at least a portion of the document data to a client serving circuit. The client serving circuit may be structured to implement a unified document surface interface in response to the at least a portion of the document data, implement an extension creation interface, provide a pack implementation value to the document serving circuit in response to user interactions with the extension creation interface, and determine an executable object in response to the pack implementation value.

Abstract: A toy figure, with an upper torso; a shoulder flange rotatably mounted on the upper torso; and an extendable arm pivotally mounted to the shoulder flange. The extendable arm may pivot with respect to both the shoulder flange and the upper torso to extend away from the upper torso, and includes an elbow that allows the extendable arm to straighten and bend. The toy figure includes an actuating mechanism disposed within the upper torso that forces the extendable arm to pivot and extend away from the upper torso. A tie rod may interconnect the shoulder flange to a portion of the extendable arm through the elbow so that so that pivotal movement of the arm around the shoulder flange causes the extendable arm to straighten.

Abstract: The movements of a self-propellable toy are controlled by an on-board infrared light transmitter and receiver and a control subcircuit operative for detecting obstacles in the forward path of advancement of the toy, and for causing the toy to either advance forwardly toward the detected obstacle or to turn away from the same, in dependence upon a selected control mode.
