Patent number: 8118438Abstract: Methods and apparatus for projecting a tangible image of data characterizing an object onto a surface of the object itself. Three-dimensional measurements of the object are obtained, the measurements are processed for projection, and a tangible image is projected onto the object, the image conveying information based on the three-dimensional measurements. The image may be projected concurrently with performance of measurements. In an exemplary dental context, information derived in part from three-dimensional measurements of a tooth or replica may be projected onto the actual tooth or replica. In interactive application, a work piece is be measured during the course of fabrication, and three-dimensional information, derived from contemporaneous non-contact measurement, is projected onto the work piece in order to direct the user with the formation of the work piece.Type: GrantFiled: July 24, 2009Date of Patent: February 21, 2012Assignee: Optimet, Optical Metrology Ltd.Inventors: Yitzhak Daniel, Kalman Wilner, Freddy Paz

Patent number: 6540363Abstract: A high-reliability display system is disclosed. The display system includes a plurality of projection channels. Each projection channel projects a substantially mutually exclusive portion of an image onto a display area. A controller determines the content and size of each portion that each projection channel projects onto the display area so that the image substantially fills the display area during normal conditions. When one of the projection channels is inoperative, the controller adjusts the portions of the image that are projected by the operative projection channels to optimize the image on the display area.Type: GrantFiled: September 1, 2000Date of Patent: April 1, 2003Assignee: Rockwell Collins, Inc.Inventor: Martin J.

Patent number: 6460999Abstract: Disclosed are a projector and the protector thereof having superior safety and practicality. The projector for projecting an image on a screen comprises sensors for performing detection in an area to be subjected to detection that is a local space. The local space is located on the outside of a projection space area which projecting light passes through, and extends along an outer edge of the projection space area. When the sensors detect an object in the area to be subjected to detection, a general controller of the projector turns off a power source of a lamp unit that is a light emitting source, and thus the general controller causes the projector to stop projecting. This prevents damage to the eyes of a person who carelessly looks into a projection lens.Type: GrantFiled: September 1, 2000Date of Patent: October 8, 2002Assignee: Sony CorporationInventor: Toshio Suzuki

Patent number: 4912751Abstract: In a method of establishing and writing a pattern which, when placed in a light beam from a projector, produces an illuminated area of any shape and size displayed on a screen, a reference point is defined which, when projected onto the screen, forms a contrasted light area thereon. The reference point is moved in the light beam so that its trajectory defines an illuminated area of required shape displaying this movement. This trajectory is written onto a pattern storage device simultaneously with or subsequently to movement of the reference point. The device for implementing this method comprises a plate incorporating a plurality of writable locations, a displacement device for moving from location to location, a pattern defining device, a memorizing device and a pattern writing device. The method and device are primarily intended for use in the theatre and entertainment for producing luminous decorative effects and luminous areas related to the decor, objects and persons in the projection space.Type: GrantFiled: May 10, 1988Date of Patent: March 27, 1990Inventor: Didier Leclercq
