Abstract: A scissor assembly includes a scissor apparatus having a first scissor jaw and a second scissor jaw that are coupled together. The first scissor jaw has a first jaw face, and the second scissor jaw has a second jaw face that opposes the first jaw face. The scissor apparatus is configured to actuate between a closed position and a plurality of open positions. The scissor assembly includes a pivot pin extending through the first and second scissor jaws. The first and second jaws are configured to rotate around the pivot pin as the scissor apparatus actuates between the closed position and the open positions. The scissor assembly includes a dynamic pin positioned between the first jaw face and the second jaw face. The scissor assembly includes a biasing member positioned at least partially around the scissor apparatus and configured to bias the scissor apparatus toward the closed position.

Abstract: A system and method for removing one or more predetermined gases from an environment is herein disclosed. An embodiment of the system and method will now be described. A means for conveying a fluid and a means for flowing the fluid is combined with adsorber and desorber sections. The fluid flows in the means for conveying the fluid by the means for flowing the fluid. Comparably, the fluid flows in the adsorber and desorber sections not by the means for flowing the fluid, but rather by capillary action. In the adsorber section, the environment is in direct contact with the fluid. The fluid is capable for adsorbing one or more gases from the environment. The fluid exits the adsorber section and subsequently flows into the desorber section. The desorber section is self-contained wherein an inner portion of the desorber section is not in direct contact with the environment. In the desorber section, the one or more gases are desorbed from the fluid into the inner portion of the desorber section. In an embodiment, the one or more gases exit the desorber section and the system as a whole.

Abstract: Various embodiments provide ice mitigating surface coatings and methods for applying ice mitigating surface coatings. Various embodiment ice mitigating surface coatings may be formed by hydrolysis of one or more substituted n-alkyldimethylalkoxysilanes terminated with functionalities having the following characteristics with respect to water: 1) non-polar interactions; 2) hydrogen bonding through donor and acceptor interactions; or 3) hydrogen bonding through acceptor interactions only. The substituted n-alkyldimethylalkoxysilanes of the various embodiments may include methyl terminated species, hydroxyl terminated species, ethylene glycol terminated species, and methoxyethylene glycol terminated species. Various embodiment ice mitigating surface coatings may be applied to metal surfaces, such as aluminum surfaces. Various embodiment substituted n-alkyldimethylalkoxysilanes may have an aliphatic chain that is saturated and liner or branched or that is partially unsaturated and liner or branched.

Abstract: A soft lithography template or stamp is made by casting a polydimethysiloxane (PDMS) or other suitable elastomeric precursor onto a master pattern. The master pattern may be formed utilizing known micro-fabrication techniques. The PDMS template includes an inverse copy of the micro-structures on the master pattern, and can be placed into a mold used to prepare a carbon-fiber reinforced polymer composite part or other polymer molding systems where a matrix material passes through a fluid state during the cure process. The liquid resin material flows into the structures on the surface of the PDMS template and hardens during the curing cycle. After the part is released from the mold, the PDMS template can be peeled from the surface of the part to reveal the free standing micro structures which are a replica of the master pattern.

Abstract: A method of fabricating (printing) parts utilizing flexible filaments includes anchoring a portion of a flexible filament to a substrate. A length of flexible filament is extended over the substrate while the flexible filament is in tension to thereby avoid buckling of the flexible filament. The flexible filament may comprise a thermoplastic material and fibers or other reinforcing materials whereby composite 3D parts can be fabricated.

Abstract: The present invention provides a system for delivering a time-varying stimulation field to a subject. In the system, a power source, a control component and a transmission component operate as a stimulation field generator to provide a predetermined time-varying stimulation field to up-regulate or down-regulate an expression level of human genes. The present invention also provides a wearable apparatus for delivering the time-varying magnetic field to mammalian cells associated with bone formation in a subject. The wearable apparatus contains the stimulation field generator in a housing. The resulted modification on gene regulation of these genes and mammalian cells promotes the retention, repair of and reduction of compromised mammalian cartilage, bone, and associated tissue.
