Publication number: 20100309436Abstract: Slides are selectively presented via a slide presentation system based upon a priority level assigned to a slide presentation. The assigned priority level indicates which of the slides to selectively present and includes a first priority level of at least two priority levels associated with the slide presentation. A request is received during the selective presentation of the slides, via an input device associated with the slide presentation system, to change the priority level assigned to the slide presentation to a second priority level of the at least two priority levels. The remaining slides of the slide presentation are selectively presented via the slide presentation system based upon the second priority level.

Patent number: 7806533Abstract: An optical system comprises a first image capture device for capturing an image of an observation area, a first display device, a semi-reflecting plate, a concave mirror disposed facing the first display device, and a second display device for displaying a background image. A light beam is scattered by the first display device through the semi-reflecting plate and then reflected by the mirror and the semi-reflecting plate in order to display an aerial image between the semi-reflecting plate and the observation area. A projector projects a light beam toward one of the display devices. The first image capture device is adapted to capture the image of the observation area via said one display device. A alternating control device alternates capture of an image of the observation area by the first image capture device and projection of the light beam projected by the projector.Type: GrantFiled: June 15, 2007Date of Patent: October 5, 2010Assignee: France TelecomInventors: Olivier Boute, Olivier Gachignard

Patent number: 7274382Abstract: This invention provides systems and methods that allow a user to change the size of a background used with a graphics-based user interface. This enables tailored background sizes based on user preference and allowable conditions, which are particularly useful with display devices having a large display area. By custom sizing a background to current conditions, a user may navigate an image among obstacles at a receiving surface and obstacles along a projection path between a projection lens and receiving surface. In addition, a user may customize the background size on a large LCD screen according to more suitable dimensions for an image used in the background or to a personal preference, thereby creating a personalized look and feel for the graphics-based user interface. One embodiment of the present invention defines a usable area for a graphics-based user interface according to the current size of the background.Type: GrantFiled: July 15, 2004Date of Patent: September 25, 2007Inventor: William J.

Patent number: 5790084Abstract: An electronic transparency device is provided with a memory in which a plurality of frames of video data ("slides") can be stored. The apparatus includes a control microprocessor which can cause predefined sequences of slides to be presented on the LCD panel automatically. These slide "shows" are defined by the user using a hand held remote control unit in conjuntion with menus displayed on the LCD panel in window fashion by the microprocessor. The user can specify the duration that each slide in a sequence is to be shown, the video transition by which it is to be introduced, the degree of "windowshading" with which it is to be displayed, etc. Once a show is defined, it can be instituted and controlled from the remote control unit. Among other numerous features, the transparency also includes a pointer that can be superimposed on the display and controlled by the remote control unit. This pointer can be used to define certain portions of the screen that are to be displayed in highlighted fashion.Type: GrantFiled: February 17, 1995Date of Patent: August 4, 1998Assignee: In Focus Systems, Inc.Inventors: Steven R.

Patent number: 4431282Abstract: Diapositives are mounted in a strip formed by a pair of flexible sheet members each having at least two picture openings therein in side-by-side relationship and the sheet members are fastened to each other in face-to-face relationship mutually offset by a single picture opening. The frame is interposed between the sheet members and a diapositive is moveably positioned within an opening in the frame. The thickness of the frame is greater than that of the diapositive so that a diapositive is freely moveable within a frame opening and has play between the sheet members. An apparatus for projecting the strip mounted diapositives is provided with a pair of cassettes one of which contains a strip in which the diapositives are mounted and the second cassette contains a strip without any diapositives. The ends of the strips are automatically connected to each other for successively introducing the diapositives into the apparatus.Type: GrantFiled: September 13, 1982Date of Patent: February 14, 1984Inventor: Liesel Martin geb.

Patent number: 4385816Abstract: A slide previewer/sorter/stack loader having a holder (18) which is adapted to receive two photographic slides in first and second receptacles at one end thereof. The holder is initially positioned at an angle above horizontal so that a first slide placed on a chute (16, 17) will drop into the first receptacle by force of gravity. When in the initial position, the slide in the holder is illuminated by a back light so that the slide can be previewed through a window in the holder and edited. The holder pivots in such a manner that the second receptacle can be positioned over a slide slot (28) above a projector. Means (26) are provided to restrain the slide in the first receptacle during transit from the initial viewing position to the position wherein the second receptacle is positioned over the slide slot. A second slide in the projector is forced upward by the projector slide lifter mechanism into the second receptacle in the holder, and is retained therein by a latch (52).Type: GrantFiled: January 4, 1982Date of Patent: May 31, 1983Inventor: Owen L.

Patent number: 4133605Abstract: A system for previewing and projecting slides that are stored in spaced, co-planar relation in a planar holder is disclosed. The slides are previewed, either individually or in a group, in their natural orientation without removing the slides from the holder. Projection of the slides to form a naturally oriented image also is accomplished without removing the slides from the holder. In the preferred embodiment, means are provided for moving the planar slide holder orthogonally with respect to the optical axis of the projection system. A slide indexing system is provided to allow the projectionist to select a particular slide for projection. The slide indexing system utilizes cooperative means on the slide holder and projector to achieve indexing and, if desired, other control functions. In an alternative embodiment, the projected image plane is vertical and can be rotated about a vertical axis at the projector without moving the base of the projector.Type: GrantFiled: June 29, 1976Date of Patent: January 9, 1979Inventor: Blanton C.
