Disclosed aspects relate to a structure which includes shape memory materials having transition triggers to transition the shape memory materials between initial states and transitioned states. A first physical shape of the structure exists when the first shape memory material has the first initial state and the second shape memory material has the second initial state. A second physical shape of the structure exists when the first shape memory material has the first transitioned state and the second shape memory material has the second initial state. A third physical shape of the structure exists when the first shape memory material has the first transitioned state and the second shape memory material has the second transitioned state. The physical shapes of the structure are reversible in nature. In embodiments, the shape memory materials are bonded to a flexible substrate or are clad together.

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.

A method of forming a coaxial wire that includes providing a sacrificial trace structure using an additive forming method, the sacrificial trace structure having a geometry for the coaxial wire, and forming a continuous seed metal layer on the sacrificial trace structure. The sacrificial trace structure may be removed and a first interconnect metal layer may be formed on the continuous seed layer. An electrically insulative layer may then be formed on the first interconnect metal layer, and a second interconnect metal layer is formed on the electrically insulative layer. Thereafter, a dielectric material is formed on the second interconnect metal layer to encapsulate a majority of an assembly of the first interconnect metal layer, electrically insulative layer and second interconnect metal layer that provides said coaxial wire. Ends of the coaxial wire may be exposed through opposing surfaces of the dielectric material to provide that the coaxial wire extends through that dielectric material.

A method of forming an interconnect that includes providing a sacrificial trace structure using an additive forming method. The sacrificial trace structure having a geometry for the interconnect. The method continuous with forming a continuous seed metal layer on the sacrificial trace structure; and removing the sacrificial trace structure, wherein the continuous seed metal layer remains. An interconnect metal layer may be formed on the continuous seed layer. A dielectric material may then be formed on the interconnect metal layer to encapsulate a majority of the interconnect metal layer, wherein ends of the interconnect metal layer are exposed through one surface of the dielectric material to provide an interconnect extending into a dielectric material.

A computing device detects that an ignition switch of the vehicle was activated, wherein the vehicle includes a navigation device. The computing device requests a destination from the navigation device. The computing device interlocking, an operation of the vehicle based on determining that the destination is not valid.

A method includes generating a graphical display based on chemical analysis data. The method also includes receiving input selecting a graphical component of the graphical display. The graphical component corresponds to a chemical or elemental constituent represented in the chemical analysis data. The method also includes receiving a specimen identifier indicating a specimen that was analyzed to generate the chemical analysis data. The method further includes generating a search query based on the specimen identifier and based on a constituent identifier of the chemical or elemental constituent and performing a search based on the search query to identify potential sources of the chemical or elemental constituent.

A device for detecting toxic shock syndrome toxins includes a pad and a membrane coupled to the pad. The pad includes first antibodies that include a first particular antibody and a second particular antibody. Each of the first antibodies are associated with toxic shock syndrome toxin one (TSST-1). The first particular antibody is configured to react with a TSST-1 antigen to form an antibody complex. The membrane includes a first zone that includes an immobilized second antibody configured to react with the antibody complex to cause a first indication. The membrane further includes a second zone that includes a third antibody configured to react with the second particular antibody to cause a second indication.
