Abstract: A dispensing system includes a filament extruder that lays filament solutions. The filament extruder comprises multiple extruder sets. Each extruder set includes a first and a second extruder. Each of the first and the second extruder includes an extruder portion, a hot end portion, and a shroud. The extruder portion includes a first and a second insert that combine to form a channel and a needle tube that receives the filament solution from the channel and lays the filament solution on the target surface.

Abstract: Interactive systems and methods for creating game and game-like applications are presented. A game system includes a content management system with access to game templates and a game content database, a plurality of REST application services, one or more user interfaces, an active game-play database, and a social reporting engine for collecting and storing user data in a user database. The game creation system includes access to external data feeds for tracking the progress and outcome of real-world events, such as sporting events. Games may be built using an editorial workflow interface for approving or rejecting game templates and game content. A crowd wisdom module analyzes game play and identifies the best answers over time, and a crowd guru module identifies players who perform well over time.

Abstract: An apparatus to receive a filament material and to move the filament while guiding a direction of movement of the filament comprising: a metal block that defines a first guide passage sized to receive the filament; wherein the block includes a first plate that includes a first surface that defines a first groove and includes a second plate that includes a second surface that defines a second groove; and wherein the first and second faces of the first and second plates are in abutting contact with the first and second grooves aligned to define the first guide passage; a drive mechanism configured to move the filament into the first guide passage.

Abstract: A print head is described for use in a computer controlled machine that uses fused filament fabrication to produce a three dimensional object.

Abstract: An annotation system includes first annotation data for annotating a manifestation of a first instance of a first XML document. The first instance of the first XML document is served by a document system. The first annotation data includes a first XML document identifier for the first XML document. The first annotation data is uniquely identified by a first annotation data identifier. The document system is configured to respond to a request containing the first XML document identifier with a manifestation of a second instance of the first XML document. The annotation system: (A) receives a request containing the first annotation data identifier; (B) issues a request containing the first XML document identifier to the document system; and (C) in response to the request containing the first annotation data identifier, manifests the first annotation data in connection with a manifestation of a second instance of the XML document.

Abstract: An annotation system receives a request from a requester to perform an operation on first annotation data for annotating a first instance of a first XML document. The operation is at least one of a create, read, update, and delete operation. The first instance of the first XML document is served by a document server component of a document system. The document system is functionally independent of the annotation system. The request explicitly addresses the first annotation data by means of an application programming interface in the annotation system. The annotation system performs the operation on the first annotation data in response to the request.

Abstract: A first instance of a first XML document is served by a document server component of a document system. An annotation system that is functionally independent of the document system semantically analyzes content and structure of the first instance of the first XML document to identify a first instance of a first target for first annotation content, wherein the first target is not text. The annotation system also generates target locating data for locating a second instance of the first target in a second instance of the first XML document. The annotation system stores the target locating data.

Abstract: An annotation system receives a first annotation input representing first annotation content for temporally annotating a first instance of a first target in a first instance of a first XML document. The first instance of the first XML document is served by a document server component of a document system. The annotation system is functionally independent of the document system. The annotation system temporally annotates the first instance of the first target with the first annotation content. The annotation subsequently manifests the first annotation content in connection with a manifestation of a second instance of the first target in a manifestation of a second instance of the first XML document served by the document server.
