US Patent:

6473238, Oct 29, 2002

Filed:

Mar 17, 2001

Appl. No.:

09/811298

Inventors:

Stephen Daniell - Easthampton MA 01027

International Classification:

G02B 2710

US Classification:

359622, 359796, 359619, 359621, 359626

Abstract:

Lens systems and an array of lenses for reproduction, capture and display of three dimensional images. The arrays generally fall into two categories. The first type of array uses air as the low-index material. This type of array may be used, for example, in illuminated displays electronic image detection, machine vision, and real-time 3D video capture. A second type of array uses a fluoropolymer as the low-index material, and conveys a great preponderance all incident light to the image plane.

Appl. No.:

09/811212

Inventors:

Stephen Daniell - Easthampton MA

Assignee:

Zograph, LLC - Northampton MA

International Classification:

G02B 2710

US Classification:

359622, 359626

Abstract:

A lens system which has a first optical boundary with a radius of curvature R, a second optical boundary located substantially a distance R from the first boundary, and a third optical boundary nearer to the second optical boundary than R. Secondly, a lens system providing optical field limitation using total internal reflection. Also, an array of lenses for reproduction, capture and display of three dimensional images discussed.

Appl. No.:

10/208325

Inventors:

Stephen Daniell - Northampton MA, US

Assignee:

Zograph, LLC - Northampton MA

International Classification:

B29D011/00
B29C033/40

US Classification:

264/002500, 264/219000

Abstract:

A relief master is formed by assembly of previously molded, machined, or otherwise fabricated relief structures. The relief structures may be quite small and include a relief geometry, i.e., a topology of interest, and a positioning feature. The relief structures are mounted on a rigid (e.g., metal) substrate that includes a plurality of positioning features complementary to the positioning features in the relief structures. The relief master is assembled through selective application and positioning of the small-scale relief structures, and can then be used as a pattern for diverse surface replication processes, including the fabrication of durable metal mold faces for casting, embossing, compression molding, and injection molding of complex patterned surfaces.

Appl. No.:

12/014837

Inventors:

Stephen Daniell - Northampton MA, US

Assignee:

Strategic Patent Acquisitions LLC - Wexford PA

International Classification:

G02B 27/22

US Classification:

359463, 359462

Abstract:

Techniques for three dimensional displays are described. An apparatus may comprise a first prism array having a first set of faceted prism elements arranged to optically couple with a second prism array having a second set of faceted prism elements, the first prism array and the second prism array to provide a null refractive component when the first set of faceted prism elements are in a first position relative to the second set of faceted prism elements, and a directional refractive component when the first set of faceted prism elements are in a second position relative to the second set of faceted prism elements. Other embodiments are described and claimed.

International Classification:

B41F 1/34
G06F 3/12

US Classification:

101481, 101485, 358 115

Abstract:

An automated lenticular photographic system includes an interface that permits a user to upload image files and image processing and printing equipment that is in communication with the interface for receiving the uploaded image files and processing the uploaded image files to create an interlaced print image file that is used to produce an interlaced print sheet containing interlaced print images. A pair of registration marks is formed on the interlaced print sheet outside of borders of the interlaced print images. The system also includes a processing station where the interlaced print sheet is aligned with a lenticular lens sheet with a registration system that detects whether the lenticular lens sheet is off-centered and skewed relative to the interlaced print sheet. The system also includes means for controllably adjusting the position of the lenticular lens sheet relative to the interlaced print sheet until proper registration between the lenticular lens sheet and the interlaced print sheet is achieved. The lenticular lens sheet is at least selectively joined to the interlaced print sheet to provide a lenticular product that can be delivered back to the user.

Abstract:

An automated lenticular photographic system includes an interface that permits a user to upload image files and image processing and printing equipment that is in communication with the interface for receiving the uploaded image files and processing the uploaded image files to create an interlaced print image file that is used to produce an interlaced print sheet containing interlaced print images. A pair of registration marks is formed on the interlaced print sheet outside of borders of the interlaced print images to assist in aligning the interlaced print sheet with a lenticular lens sheet. A registration system detects whether the lenticular lens sheet is off-centered and skewed relative to the interlaced print sheet.
