Abstract:
A method of manufacturing polymeric currency utilizing three dimensional objects may include forming a first and second layer of biaxially oriented polypropylene. Ink may be selectively applied to one or more portions of one or more sides of the first layer of biaxially oriented polypropylene. In response to applying the ink, one or more apertures may be created into the second layer of biaxially oriented polypropylene. The first and second layers of biaxially oriented polypropylene may be laminated together. A three dimensional object may be printed within the one or more apertures in the second layer of biaxially oriented polypropylene. In response to printing, a protective overcoat may be applied on top of the second layer of biaxially oriented polypropylene.
Abstract:
In an example, a process for bonding a microcapsule having an encapsulating payload to a polymeric material. The process includes applying a microcapsule (having the encapsulated payload) that includes a dienophile functional group to a polymeric material that includes a diene functional group. The process further includes bonding the microcapsule having the encapsulated payload to the polymeric material via a chemical reaction of the dienophile functional group with the diene functional group.
Abstract:
A bioderived based plasticizer is produced by reacting a bioderived diol (and/or a bioderived alcohol) and a bioderived carboxylic acid in the presence of N,N′-dicyclohexylcarbodiimide (DCC), wherein the bioderived carboxylic acid includes a hydrolyzed oil. The bioderived carboxylic acid (e.g., linoleic acid, α-linolenic acid, oleic acid, and mixtures thereof) may be produced by hydrolyzing a triglyceride, such as canola oil, linseed oil, soybean oil, and mixtures thereof. In one embodiment of the present invention, a bioderived based plasticizer is produced by reacting 2,5-bis-(hydroxymethyl)furan and α-linolenic acid in the presence of DCC. In some embodiments of the present invention, the bioderived based plasticizer is blended into one or more polymers.
Abstract:
An automated multi-fluid cooling system and method are provided for cooling an electronic component(s). The cooling system includes a coolant loop, a coolant tank, multiple valves, and a controller. The coolant loop is at least partially exposed to outdoor ambient air temperature(s) during normal operation, and the coolant tank includes first and second reservoirs containing first and second fluids, respectively. The first fluid freezes at a lower temperature than the second, the second fluid has superior cooling properties compared with the first, and the two fluids are soluble. The multiple valves are controllable to selectively couple the first or second fluid into the coolant in the coolant loop, wherein the coolant includes at least the second fluid. The controller automatically controls the valves to vary first fluid concentration level in the coolant loop based on historical, current, or anticipated outdoor air ambient temperature(s) for a time of year.
Abstract:
A fluorescent material may include a medium, carbon nanotubes dispersed in the medium, and a fluorescent surfactant. The fluorescent surfactant may be adsorbed to a surface of some of the carbon nanotubes in a concentration sufficient to make the material fluoresce in the presence of radiation. The material may be applied to a material and tested for fluorescence, electrical conductivity, or carbon nanotube structure.
Abstract:
A multilayer hose is provided with a leak preventative interfacial layer that includes a super absorbent polymer (SAP) interposed between an inner layer and an outer layer. In one embodiment, the inner and outer layers are made of ethylene propylene diene monomer (M-class) (EPDM) rubber, and the interfacial layer is covalently bonded to the inner layer (and, optionally, to the outer layer) via a curing reaction between the EPDM rubber of at least the inner layer and a vinyl functionalized reaction product of alginic acid and acryloyl chloride of the interfacial layer. In addition, a reinforcement layer (e.g., textile filaments braided, knitted, or spirally wound onto the interfacial layer) is disposed between the inner and outer layers. In some embodiments, one or more SAP-equipped multilayer hoses interconnect liquid-coolant cooling system components (e.g., cold plates, headers, manifolds, pumps, reservoirs, and heat exchangers) of an apparatus that removes heat from electronic components.
Abstract:
A computer-implemented method for text block segmentation includes determining a first text block segmentation pattern utilized to generate a segmented text block based, at least in part, on a comparison of semantic information associated with the segmented text block and a plurality of predefined types of text block segmentation patterns indicated by a graph; calculating a first degree of confidence in a size of the segmented text block based, at least in part, on comparing semantic entities associated with the segmented text block with semantic entities indicated by leaf nodes stemming from a first non-leaf node included in the graph and representative of the first type of text block segmentation pattern; and determining that the size of the segmented text block is non-optimal based on the calculated degree of confidence in the size of the segmented text block being below a predetermined threshold.
Abstract:
An approach for assisting software developers to fill the data gap and reproducing client application issue using reported reproducing steps is disclosed. The approach involves constructing service request/response sequence (from the developer's side based on the limited data) from customer's reproducing steps and developer's running inspection result and perform UI-service mapping, redirecting service call to data simulator which replay the service request and response, and adjusting service response with multiple data sources and policies. Lastly, the approach can transform the issue to an automatic test script with the service response in a mockup function (e.g., can be used to extend test data and enhance test cases).
Abstract:
A carbene-coated metal foil is produced by applying an N-heterocyclic carbene (NHC) compound to one or more surfaces of a metal foil (e.g., an electrodeposited copper foil having a surface that is smooth and non-oxidized). The NHC compound contains a matrix-reactive pendant group that includes at least one of a vinyl-, allyl-, acrylic-, methacrylic-, styrenic-, amine-, amide- and epoxy-containing moiety capable of reacting with a base polymer (e.g., a vinyl-containing resin such as a polyphenylene oxide/triallyl-isocyanurate (PPO/TAIC) composition). The NHC compound may be synthesized by, for example, reacting a halogenated imidazolium salt (e.g., 1,3-bis(4-bromo-2,6-dimethylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride) and an organostannane having a vinyl-containing moiety (e.g., tributyl(vinyl)stannane) in the presence of a palladium catalyst. In some embodiments, an enhanced substrate for a printed circuit board (PCB) is produced by laminating the carbene-coated metal foil to a substrate that includes glass fiber impregnated with the base polymer.
