  • Publication number: 20240161602
    Abstract: A system and method are provided herein for communicating with and controlling various devices using visible light communication (VLC). According to one embodiment, a method is provided for extending a communication range of a VLC system comprising a plurality of controlled devices and a remote-control device. Such a method may include, for example, transmitting a communication message from a remote-control device to a first controlled device located within range of the remote-control device, wherein the communication message is transmitted through free space using visible light, and extending the communication range of the VLC system to a second controlled device, which is located outside of the range of the remote-control device, by using the first controlled device to retransmit the communication message through free space using visible light to the second controlled device.

  • Patent number: 6100310
    Abstract: Microcellular elastomers and a process for making them are disclosed. The process comprises reacting a resin component ("B" side) with an isocyanate-terminated prepolymer ("A" side). Pre-reacting the right proportion of chain extender into an "A" side that also includes a high-primary, low-unsaturation polyol is the key to making low-density (less than 0.5 g/cm.sup.3) microcellular elastomers while avoiding problems with poor processing or inferior physical properties. The process is easy to practice, and provides lighter, high-quality polyurethane products, including protective sports equipment, arm rests or steering wheels for the auto industry, and midsoles or shoe soles for footwear.

  • Patent number: 5856372
    Abstract: Microcellular polyurethane elastomer shoe sole components have exceptional physical properties may be prepared from isocyanate-terminated prepolymers derived from polyoxypropylene diols having a molecular weight of from about 2000 Da to 8000 Da, an unsaturation less than about 0.02 meq/g, and a random oxyethylene content of from about 5 to about 15 weight percent. The shoe sole components exhibit high tensile strength, elongation, resilience, and in addition have excellent tear strength, particularly 90.degree. angle tear.

  • Patent number: 5266234
    Abstract: The invention pertains to a water blown integral skin polyurethane foam having a skin with good abrasion resistance. The foam is manufactured by employing as a polyol composition a polyol having a functionality of from 1.75 to 2.65 and a molecular weight of from 1500 to 5000 along with a surfactant and water as a blowing agent. The particular surfactant is a particular siloxane or an ethylene oxide adduct of octylphenol.
