Abstract: The present invention is a modular electronic sign having a plurality of display units assembled on a mounting track and connected to a sign controller. Each display unit has a circuit board having a plurality of light emitting diodes arranged in a pattern thereon A microprocessor in each display unit is in communication with the sign controller and adjacent display units. Each display unit is environmentally sealed to avoid a separate enclosure for the modular sign. A plurality of standoffs are used to electrically connect the display units to power and communications conductors and mechanically connect the display units to the mounting track.

Abstract: A height adjustable bed and storage unit for small living quarters in which substantially vertical posts are fixedly attached to the floor and ceiling of the living quarters. Each post includes a mating structure for mating to a cross-member at a plurality of vertical positions, the cross-member being utilized for holding a platform substantially horizontally. The cross-member is releasable from the mating structure without the use of tools.
