Abstract: A multi-color segmented LED or other light emitting arrangement display includes specially designed segments such that there are two or more rooms within one segment. When one or more LEDs or light emitting arrangements with different colors are placed in each room of a segment, the segment will generate a very special light effect—a multi-colored segment. In one aspect, it is possible to control the height of the wall between rooms such that a mixed color light effect is produced between the adjacent rooms. The multi-color segmented display can be used in a variety of applications.

Abstract: A radio system for use in a building within a range of an over-the-air radio broadcast timing signal that indicates a reference time includes a central radio device located at the building and having a radio receiver configured to receive the timing signal. The central radio device produces an output signal based on the timing signal. Each appliance has a clock, and receives the output signal. Each appliance sets the clock based on the central radio device output signal.
