  • Polyurethane elastomers from HDI prepolymers with reduced content of free HDI monomers
    Publication number: 20050124777
    Abstract: Polyurethane prepolymers with reduced amount of unreacted monomeric hexamethylene 1,6-diisocyanate (HDI) are provided. Also provided are polyurethane elastomers obtained by mixing the polyurethane prepolymers having reduced amount of unreacted monomeric HDI with amine and/or hydroxy chain extenders and durable, resilient, colorfast golf ball covers obtained therefrom. Rolls, wheels and tires obtained from the polyurethane elastomers are also provided.

  • Multidimensional hybrid mouse for computers
    Patent number: 5446481
    Abstract: A hybrid mouse combining the usual x and y motion signals usually found in mice together with additional degrees of freedom, particularly a z-axis signal. The z-axis signal is generated by a roller whose turning motion is sensed by a shaft angle encoder, including a light chopper. Additional degrees of freedom may be provided by tilting the roller left and right to actuate switches. Actuation of each switch, together with pulse counts from the roller may be used to indicate pitch and roll. A yaw motion signal may be provided by use of dual position detectors. In another embodiment, pitch and roll may be indicated by a trackball mounted on the mouse housing with or without the z-axis roller.
