Abstract: A scalable expandable spray ink printer machine for use with paper roll stock is disclosed. A series of three or four print heads are place serially in proximity to paper stock. The configuration of the cylindrical print head allows the heads to be expanded for printing on wider paper stock. The print heads include a combination of fixed, turning and sliding components to align or block ink flow from the print ink reservoir. The printer is in fixed position perpendicular to the travel direction and rotates internally on an axis parallel to the paper or media to be printed. The print head is sectional and lengthwise expandable in fixed unit lengths. The printing machine is ideally suited for advertising or other elongated print media. Due to the use of standard paper, roll stock and speed of the printing, signs can be printed on demand and displayed in real-time.

Abstract: A printing machine for use with paper roll stock is disclosed. The print head consists of an expandable cylindrical ring print head where the printing brushes are integrated in a spiral pattern around the ring print head. Ink wells are located outside of the print head, and electromagnets, located outside of the ring print head, attract or repel the print brushes towards or away from the ink wells or paper. The printing machine is ideally suited for advertising or other elongated print media. Due to the use of standard paper roll stock and speed of the printing, signs can be printed on demand and displayed in a real-time basis. Two printing machines can be configured to print on both sides of the paper at the same time with the same or different images being printed on each side.

Abstract: A Braille reading apparatus has a base unit presenting a planar upfacing surface and a traveling Braille character carriage. A cover unit is engaged with the base unit and provides a flexible membrane covering the upfacing surface and the carriage. The character carriage is enabled for moving across the base unit and provides plural character read units in linear sequence between its opposing ends. Each of the read units provides Braille character presentation in contact with an underside of the membrane, whereby, a page of Braille is readable through tactile contact, moving between the opposing ends of the character carriage over an outside surface of the membrane, as the character carriage moves over the base unit scanning from one end to the other.
