  • Patent number: 8886412
    Abstract: A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A main controller signals a secondary steering assembly to operate in a first phase when a power steering controller is in a first mode and a second phase to steer the vehicle when the power steering controller is in a second mode. The main controller signals a friction device to actuate to a disengaged position when the power steering controller is in the first mode and the secondary steering assembly is in the first phase, and to signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the secondary steering assembly is in the second phase to allow the secondary steering assembly to steer the vehicle.

  • Publication number: 20050175856
    Abstract: Disclosed are electroluminescent devices that comprise organic layers that contain certain 2H-benzotriazole compounds. The 2H-benzotriazole compounds of blue-emitting, durable, organo-electrouminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.

  • Publication number: 20050043543
    Abstract: Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.
