Abstract: A process of evaluating performance of a positive crankcase ventilation (PCV) valve is disclosed. The process includes utilizing an optical sensor coupled to the PCV valve to collect baseline valve position data during a calibration phase. The baseline valve position data represents satisfactory PCV valve performance. The process also includes utilizing the optical sensor to collect operational valve position data during an operational phase. The process further includes determining whether a deviation of the operational valve position data from the baseline valve position data satisfies a performance threshold associated with unsatisfactory PCV valve performance. When the deviation satisfies the performance threshold, the process includes communicating an error code to an alert indicator.

Abstract: A quality-sensing bottle cap includes a sensor array having a plurality of conductive polymeric sensors. In some embodiments, each sensor is exposed within a mechanical chamber and is in electrical communication with an interrogation interface. The mechanical chamber is configured, in an inactive state, to be closed off from a headspace above a liquid contained in a bottle sealed with the quality-sensing bottle cap and configured, in an active state, to be open to the headspace. The sensor array may be tailored for a particular application, such as the detection of olive oil aroma. The sensor array may, for example, allow discrimination among olive oils of different qualities (e.g., extra virgin olive oil, lampante virgin olive oil, and refined olive oil), as well as discrimination among olive oils with negative attributes (e.g., olive oils with unpleasant aromatic notes, such as “fusty,” “muddy sediment,” “musty,” and “rancid”).

Abstract: An inside surface of a hose for use with liquid-cooled cooling plate assemblies and other applications that contain copper (Cu) components is pre-treated with a hydrophobic coating to reduce depletion of a copper corrosion inhibitor (e.g., benzotriazole (BTA)) dissolved in a liquid coolant (e.g., deionized water) that flows through the hose. Exemplary hydrophobic coatings include, but are not limited to, polydialkylsiloxanes such as polydimethylsiloxanes. In one embodiment, a multilayer hose is immersed in a solution containing hydrophobizing siloxane monomers dissolved in a solvent. The coated multilayer hose is then dried to evaporate the solvent. As the solvent evaporates, the siloxane monomers bind together to form the hydrophobic coating. In some embodiments, one or more hoses each provided with a hydrophobic coating interconnect liquid-coolant cooling system components (e.g., cold plates, headers, manifolds, pumps, reservoirs, and heat exchangers) of a cooling apparatus that removes heat from one or more electronic components.

Abstract: A method and associated apparatus are disclosed for forming a conductive via that extends partly through a multi-layer assembly, wherein the method comprises forming a cavity from a surface of the multi-layer assembly to a first depth. The cavity extends through a plurality of layers of the multi-layer assembly. The plurality of layers comprises a healing layer comprising a plurality of microcapsules. Forming the cavity ruptures some of the plurality of microcapsules to release encapsulated material into the cavity. The released encapsulated material defines a second depth from the surface, the second depth being closer to the surface than the first depth. The method further comprises depositing conductive material within the cavity to form the conductive via that extends to the second depth.

Abstract: A triggering condition is applied to a conductive polymer positioned in a drilled hole in a printed circuit board. The applied triggering condition causes the polymer to vertically expand within the drilled hole such that the expanded polymer creates an electrically conductive path between contact pads located in different layers of the printed circuit board.

Abstract: Method, apparatus, and computer program product are provided for determining a maximum temperature to which a perishable good or other temperature sensitive item was exposed. In some embodiments, a capacitance of a circuit provided on a substrate is measured. The circuit includes capacitor(s) each having first and second plates separated from each other by an ionic liquid (IL) in a solid state. The IL melts at a predetermined temperature and flows away from the first and second plates into a void. In some embodiments, the predetermined temperature at which the IL melts is different for each capacitor. For example, each capacitor in the circuit may employ a different N-alkyl bezothiazolium salt. A maximum temperature of exposure is determined based on the measured capacitance. In some embodiments, a decision of whether to discard the perishable good or other temperature sensitive item may be based on the determined maximum temperature.

Abstract: A process includes providing furan-2,5-dicarboxylic dimethyl ester (FDME), reacting the FDME with a Grignard reagent to form a bis-alkylketone furan having R groups selected from the group consisting of a C1-C20 linear alkyl chain, a C2-C24 branched alkyl chain, and a hydrogen atom. An additional process includes mixing a 3,4-dibrominated bis-alkylketone furan with potassium carbonate, and adding ethyl-mercaptoacetate to the mixture. This process also includes stirring the mixture to form a bis-alkyl-DTF diester fused ring structure, which is then brominated to form a dibromo-DTF compound.

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.
