  • Safety Enhancement System for a Mobile Display System
    Publication number: 20190287304
    Abstract: A method and system for safety enhancement. A movement of a user of a mobile display system that displays augmented reality information is measured. Movement information about the user is relayed from the movement measured for the user. A speed at which the user is moving with respect to a structure using the movement information and a three-dimensional model of the structure is determined. A visual display of the augmented reality information on the mobile display system is deactivated when the speed at which the user is moving with respect to the structure meets a deactivation condition.

  • Ultraviolet light emitting AlGaN composition and ultraviolet light emitting device containing same
    Patent number: 8564014
    Abstract: An AlGaN composition is provided comprising a group III-Nitride active region layer, for use in an active region of a UV light emitting device, wherein light-generation occurs through radiative recombination of carriers in nanometer scale size, compositionally inhomogeneous regions having band-gap energy less than the surrounding material. Further, a semiconductor UV light emitting device having an active region layer comprised of the AlGaN composition above is provided, as well as a method of producing the AlGaN composition and semiconductor UV light emitting device, involving molecular beam epitaxy.
