Abstract: The present invention discloses a new and novel patch panel and wall unit assembly for use in local area network (LAN) wiring and installation. The patch panels and wall units include a new printed circuit board designed to simplify the installation of LAN's. The patch panels are designed to more closely mimic the wall unit configuration so that more understandable wiring layouts can be presented during LAN wiring installation.

Abstract: A system for driving a neon tube to form luminous bubbles and controlling the motion thereof in which a modulatable high AC voltage source is connected to control a pair of electronic switches in the primary circuit of a high voltage transformer which is connected to electrodes of said neon tube in such a way as to produce the luminous bubbles, which can be stationary or moved at varying speeds and direction by control of width and/or frequency of control pulses applied to the electronic switches. A memory stores predetermined patterns of the direction and speed of said luminous bubbles and microprocessor means for controlling said modulatable AC voltage in accordance with said predetermined pattern by said memory means to cause said luminous bubbles to move in said predetermined patterns of direction and speed. The memory may include a plurality of predetermined patterns stored, and selector for selecting one of said patterns and driving the neon tube therewith.
