  • System and method for printing directly on a mat board
    Patent number: 6450090
    Abstract: A system and method for printing directly on a mat board. A computer-readable medium includes a digital image having a size scaled to a size of the mat board. For example, the size can correspond to a border region of the mat board between an outer edge of the mat board and an interior region of the mat board that is open or configured to be open to allow visual access to a selected item placed behind the mat board. The digital image is transmitted to a computer printer coupled to the computer-readable medium, and the digital image is printed directly on the mat board with the computer printer while the mat board is engaged with the computer printer. The mat board can include a mat board body having a forward-facing surface with an at least partially non-porous print receiving medium configured to receive ink from an ink jet printer, and a generally non-porous medium at a rearward-facing surface configured to at least restrict moisture from passing into the mat board body through the rearward-facing surface.

  • Constant pressure load bearing air chamber
    Patent number: 5142717
    Abstract: An air chamber including a control for manually selecting a desired pressure within the chamber. Means for sensing the air pressure within the chamber are provided as are pump means for adding air to the chamber and vent means for removing air from the chamber. Control circuitry adds or removes air from the chamber responsive to the sensed pressure to maintain the pressure within the chamber at the preset level. Structural means are provided within the chamber for supporting a portion of a load placed thereon and thus decreases air pressure within the chamber to avoid deflation.
