Abstract: A method is provided for utilizing an emergency contact number in a telecommunications network (32). The method includes: identifying a first call directed to an emergency contact number; notifying a first user equipment (20) of the identified first call; recognizing a second call from the first user equipment (20) to the emergency contact number as a request to connect the second call with the first call; and, supporting a connection of the first and second calls with one another.

Abstract: An interconnection device is disclosed for optically interconnecting a plurality of optical devices. The interconnection device comprises an optically transparent spacer material having opposite surfaces with a photosensitive material, having fringes therein formed in a specified manner, fixedly positioned on one of said surfaces. The other surface of the spacer material has a plurality of positions for fixedly positioning the optical devices thereon. The fringe pattern within the photosensitive material is formed by directing a first coherent light beam through the photosensitive material and the spacer material to a first one of said plurality of positions and by directing a second coherent light beam from a second one of said plurality of positions through the transparent spacer material to interfere with the first coherent light beam in the photosensitive material.

Abstract: Method and apparatus for making a plurality (100) of reflection holograms (101-109) positioned in a two-dimensional array to interconnect optically a plurality (120) of optically nonlinear optical devices (121-129) also positioned in a two-dimensional array. The devices are operated to function as optical logic NOR gates, and the reflection holograms optically interconnect the devices to form any desired optical logic circuit such as a clocked JK sequential logic flip-flop circuit. The reflection holograms are made by affixing the devices and a photosensitive material (500) to the opposite surfaces of a layer of transparent material (505). The transparent material maintains the positions of the devices relative to the photosensitive material both before and after the holograms is made.
