摘要:
A device (20) for an automotive vehicle (10) is provided to indicate the buckled and unbuckled status of a seatbelt (24). The device (20) has a self-powered wireless switch assembly (22) that is coupled to the seatbelt (24). It provides power to power a wireless transmitter (44) to transmit a wireless signal (45) corresponding to the buckled and unbuckled state of the seatbelt (24). The self-powered wireless switch assembly (22) harvests energy from the mechanical action of the seatbelt (24). The device (20) transmits a wireless signal (45) indicating the seatbelt (24) status. The receiver (18) located in the automotive vehicle (10) receives the wireless signal (45). The wireless signal (45) is processed by a safety information system (12) and then visually and audibly displayed by an indicator (16) to alert the driver of the seatbelt (24) status.
摘要:
A system, method, and article of manufacture for reducing the rate of fuel vapor formation within a fuel storage tank include a plurality of discrete independent floating particles or elements to reduce exposed evaporative surface area of fuel in the fuel storage tank while conforming to a changing fuel tank cross-section as fuel level changes. The elements or particles may have a self-tessellating geometry to facilitate formation of a single or multi-layer barrier or cover and be made or coated with a material that resists fuel wetting and degradation, such as a highly fluorinated polymer including polytetrafluoroethylene.

摘要:
The invention relates to a thin, nano-structured coating that provides optical light efficiency enhancement. The dried coating contains nano-structures that provide a very low haze level of less than 2 percent, and a light transmission improvement of at least 1% over the non-coated substrate. For the nano-structured coating on an acrylic substrate the transmission is greater than 93 percent, and preferably greater than 94 percent. The coatings of the invention are especially useful for optical electronic displays and photovoltaic modules.

The invention relates to a one-step fluoropolymer, especially polyvinylidene fluoride (PVDF), coating for use on metals, especially use on metal fuel line and brake tubes, etc, to provide a protective barrier with superior chemical resistance, impact resistance and heat resistance as well as good flexibility. The coating composition contains, on a resin solids basis, 75-94 percent polyvinylidene fluoride resin, 5-20 percent acrylic resin, and 1-15 percent polyepoxide resin. The coating has excellent adhesion on metal substrates, particularly on non-pretreated galvanized steel, without the need for a primer coating.
摘要:
The invention relates to polymeric resin blends containing polyelectrolyte resins blended into a polymer or copolymer matrix. Specifically, the polyelectrolyte resins are (co)polymers without hydrolyzable groups. The matrix polymer is a tough, and highly chemical-resistant (co)polymer, preferably a fluoropolymer. The polymeric resin blend is useful for forming films, and especially films useful for MEAs for use in fuel cells.
