International Classification:

H04N 5/64

US Classification:

348836, 348E05128

Abstract:

Various techniques for detachably connecting a commercially-available convention picture frame to an electronic display panel, such as one used in a digital picture frame. The electronic display panel includes a display and a bordering housing surrounding the display and having an opening, that in combination with the opening in the conventional picture frame, allow the display to be visible through the openings. The height, width, and thickness of the bordering housing are configured to allow the electronic display panel to be engaged with multiple commercially-available conventional picture frames.

Gregory R. Kulzer - Rochester NY, US

International Classification:

B41J 11/00

Abstract:

A method for applying vacuum force across a width of a web of movable print medium as it moves through a printing system and determining if positions of a pair of adjustable edge seals do not correspond to the width of the movable print medium is disclosed. The method comprises defining a vacuum chamber and using a vacuum source to provide vacuum in the vacuum chamber. Sealing rollers and the adjustable edge seals define an opening in the vacuum chamber. Appropriate response curves from a plurality of response curves for different known print media are selected. First and second signals indicative of the activation level of the vacuum source and the vacuum level in the vacuum chamber are produced. The signals are compared to the response curves to produce an error signal indicating whether the position of the edge seals corresponds to the width of the print medium.

International Classification:

B41J 11/00

Abstract:

Apparatus for causing a vacuum force to be applied across a width of a print medium as it moves through a printing system and for determining whether the edge seals are positioned correctly is disclosed. A vacuum chamber is connected to a vacuum source which provides vacuum to the vacuum chamber. Spaced sealing rollers and the edge seals define an opening in the vacuum chamber, wherein the print medium passes over the opening and is guided by the sealing rollers. A sensor measures a vacuum level in the vacuum chamber. A controller stores a plurality of response curves for different known print media, produces first and second signals indicative of an activation level of the vacuum source and the vacuum level in the vacuum chamber, and compares the first and second signal to appropriate response curves to produce an error signal indicating whether the edge seals are correctly positioned.

Inventors:

- New York NY, US
Gregory R. Kulzer - Rochester NY, US

International Classification:

B41J 11/00

Abstract:

A method for generating a response curve for adjusting the positions of a pair of adjustable edge seals to the width of a print medium in a printing system is disclosed. The method comprises defining a vacuum chamber and using a vacuum source to provide vacuum in the vacuum chamber. Spaced sealing rollers and the edge seals define an opening in the vacuum chamber. Signals indicative of an activation level of the vacuum source or the vacuum level in the vacuum chamber are produced for the first position. The edge seals are moved to at least one new position. Signals indicative of the activation level of the vacuum source and the vacuum level in the vacuum chamber are produced for the new positions. A controller is used to produce a response curve using the first or second signals produced at the first and new positions.

Abstract:

A system for generating a response curve for adjusting the positions of a pair of adjustable edge seals to the width of a print medium in a printing system is disclosed. The system comprises a vacuum chamber connected to a vacuum source, which provides vacuum to the vacuum chamber. Spaced sealing rollers and edge seals define an opening in the vacuum chamber. A sensor measures a vacuum level in the vacuum chamber. A controller is used to produce signals indicative of an activation level or a vacuum level. Means for adjusting the position of the edge seals are used to reposition the edge seals to at least one new position. The controller produces signals indicative of an activation level or a vacuum level at the new positions. A response curve is produced using the signals produced at the first and new positions.
