Abstract: A method for capturing digital information on a surface of a sun visor for use by an operator and a passenger, includes the steps of: deploying the sun visor in a vehicle for: storing accessible digital information; selecting stored the digital information; accessing selected the digital information; capturing selected the digital information on the surface of the sun visor for having captured digital information, the surface of the sun visor having a light absorbing technology providing a super black surface; retrieving selected the captured digital information; transmitting selected retrieved the captured digital information; receiving selected retrieved the captured digital information; converting selected retrieved the captured digital information into a form able to be read by the operator or a passenger; and, displaying selected retrieved the captured digital information in the form able to be read on the surface on the sun visor.

Abstract: An optical disc includes an optical disc; a thermally conductive material disposed in a pattern of discrete pads on said disc; and a thermochromic material disposed over said pattern of thermally conductive material. A method of making an optical disc includes indenting a pattern onto an insulator; and depositing a thermally conductive material into indents of said pattern.

Abstract: A fuel injector includes a first input for receiving a fuel and a second input for receiving a non-fuel fluid. The fuel injector also includes a fluid ejector that includes a first drop ejector for discretely ejecting droplets of the fuel, the fluid ejector also including a second drop ejector for discretely ejecting droplets of the non-fuel fluid.
