Abstract: A low pull force system for feeding a filament along a feed path from a source to a liquefier in a 3D printer includes a low compressive force loading drive for advancing filament from the source, a feed drive for advancing filament into the liquefier, and an in-line accumulator comprising a telescoping joint positioned in the feed path between the loading drive and the feed drive. When the telescoping joint is in a contracted position, the loading drive activates to feed filament into the feed path at a rate faster than a rate at which the feed drive advances filament into the liquefier, causing the telescoping joint to expand and accrue a slack of filament in the feed path. When the telescoping joint reaches an extended position, the loading drive deactivates while the feed drive continues to advance filament into the liquefier, and the slack of filament is consumed.

Abstract: A low compressive force filament drive system for use with an additive manufacturing system includes a plurality of drives spaced from each other. Each drive includes a first rotatable shaft and a second rotatable shaft engaged with the first rotatable shaft in a counter rotational configuration. The filament drive system includes a pair of drive wheel, each fixedly attached to a shaft and comprising a groove about a circumference having a substantially smooth surface and positioned on opposing sides of a filament path with a gap therebetween so as to frictionally engage a filament provided in the filament path. The drive includes one or more bridge shafts, wherein each bridge shaft is configured to rotatably couple the adjacent drives of the plurality of drives, wherein the shafts are configured to be directly or indirectly driven by a motor.

Abstract: A computer-implemented development process of a software solution includes providing a user input screen to accept a description about a portion of a software solution and to allow creation of an associated work object relating to completion of an invention submission about a potentially patentable idea within the description. Concurrent with creating the work object, or at some later time, the process can also include generating an invention disclosure form related to the potentially patentable idea and transmitting the invention disclosure form to an invention submission process.

Abstract: A system for managing clinical treatment dispensation includes a rules engine and a treatment assignment subsystem. The rules engine is capable of receiving at least two treatment parameters from at least one treatment module and uses the treatment parameters to compute a set of treatment combinations. The treatment assignment subsystem uses the treatment combinations set to generate treatment dispensation information useful for treating a patient. A method for generating a clinical treatment dispensation design is also described.

Abstract: A system and method for the removal of metals such as mercury from a gas stream. The method involves contacting a gas stream containing the target metals with reactive chemical species generated in a plasma device. The metal to be removed is chemically converted into forms enabling capture in either conventional particulate removal devices or in a wet scrubber for the capture of a soluble chemical species.
