Abstract: A wearable fluid delivery system comprising a single-use device with a tube, a pump, and a nutrition container with a fluid. The system further includes a module including a processor, a battery, and an electric motor with an output member. The processor is configured to operate the electric motor. The single-use device is releasably coupled to the module such that the output member is coupled to the pump when the single-use device is coupled to the module, and the output member drives the pump to cause the fluid to travel through the tube.

Abstract: The present invention is an enteral nutrition gastrostomy access device. A permanent or semi-permanent stoma liner is adjustably positioned within a stoma channel extending through a patient's abdominal and stomach walls. The stoma liner is characterized by an adjustable bladder capable of applying variable torsional force to one or more pinch points along the interface between the stoma liner and the stoma. The stoma liner is configured to receive a plug with a central threaded channel, into which a cap or enteral feeding device may be wholly or partially inserted. The central threaded channel is characterized by requiring application of a linear push force to apply but requiring application of both a linear pull force and a torsional force to remove.

Abstract: An exemplary embodiment of the present invention provides a solar panel truss mounting system comprising a base and a truss assembly coupled to the base. The truss assembly comprises a first panel rail mount, second panel rail mount parallel to the first panel rail mount, base rail mount parallel to the first and second panel rail mounts, and a plurality of support members. A first portion of the plurality of support members extends between the first and second panel rail mounts. A second portion of the plurality of support members extends between the first panel rail mount and the base rail mount. A third portion of the plurality of support members extends between the second panel rail mount and the base rail mount. The system can further comprise a plurality of connectors for coupling a plurality of photovoltaic solar panels to the truss assembly.

Abstract: Systems, methods, and apparatuses for effectively increasing the structural capacity of space frames. In various embodiments, a space frame may be post-tensioned with interior cables that attach to nodes and form unique load transfer paths, thereby redistributing the member stresses and generally creating uniformity amongst stress types. Further, in various embodiments, variable space frame geometry may be employed to match the structural capacity of the space frame with the structural loads on the same, thereby modifying a space frame to comprise one or more empty bays or stretch bays.

Abstract: A server is configured to store a number of different models of an object in machine-ready form corresponding to a number of different three-dimensional printers having differing capabilities and/or hardware configurations. When a user at a client device or a printer requests the object, the server automatically determines a printer type and selects a suitable, corresponding machine-ready model for immediate fabrication by the printer.

Abstract: Apparatuses, systems, and methods for coupling adjacent solar canopies into a unitized structure to reduce wind loads on and increase the structural integrity of the solar canopies. In one embodiment, an array of two or more solar canopies may be divided into pairs of adjacent canopies, which are structurally coupled together.

Abstract: A server is configured to store a library of printable content and to select an item from the library in response to a user request. Instead of the user specifying a particular item, the server can automatically select from a number of different items. The server may automatically determine a printer type for the user and select a suitable, corresponding model for immediate fabrication by the printer.

Abstract: A device and method for locating a hanger for an object on a vertical surface, in which an elongated strip with a breakpoint of reduced tensile strength indicates the precise point for placing the hanger. The elongated strip is adhered to the rear of the object such that the breakpoint or other marker aligns with the top of the D-hook, bracket, wire, or keyhole slot. The object is positioned on the wall and a downward pressure breaks the strip leaving an indication of where the hanger should be placed.

Abstract: An extrusion assembly for a three-dimensional printer includes a plurality of extruders that can move independently relative to one another during a fabrication process. This permits concurrent extrusion over a variety of different tool paths, advantageously increasing the overall speed of fabrication. In general, the extrusion assembly as a whole may move within the x-y-z space of a build volume using conventional techniques, while one extruder is movable relative to the other, e.g., by moving radially about the other extruder in an x-y plane of the fabrication process or by moving in the z-axis of the fabrication process relative to the other extruder. Additional extruders may be usefully added to further increase the aggregate volume deposition rate in a three-dimensional fabrication process.

Abstract: An apparatus for anchoring an exercise band comprises a base panel having front and rear surfaces extending between first and second ends, wherein said rear surface is securable to an object. The apparatus further includes an arcuate panel extending from said second end to a free distal end with an intermediate portion therebetween and a slot formed through said arcuate panel sized to receive an exercise band therethrough. The arcuate panel curves away from said base panel to said front surface of said base panel.
