Abstract: An electrical interconnection device provides electrical connection between any two or more microelectronic layers in a multilayer microelectronic device, or between the layers and an external electrical device. The electrical interconnection device is a monolithic integrated circuit with a pattern of conductive paths fabricated on its surface, and is placed directly against the side edges of a multilayer microelectronic device such that the paths on the electrical interconnection device contact associated conductive pathways exposed at the side edges of the layers of the microelectronic structure.

Abstract: A programming-on-demand cable system is provided which allows any one of a plurality of individual users to request anyone of a plurality of video programs they wish to view from a library of programs, and permits the requested program to be available for viewing on a conventional television set at the user's location following a request initiated by the user. Each program is preprogrammed in a memory device selectable by a host computer at a central data station in response to an address signal transmitted from the user. The host computer in conjunction with other electronics transmits the video program at a high non-real-time rate over a fiber optic line network to a data receiving station at the user's location. The data receiving station then converts the received optical data back to electrical data and stores it for subsequent real-time transmission to the user's television set.
