Abstract: An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

Abstract: A method, apparatus, system, and software product are presented for displaying notes to a presenter, in order to facilitate narration of a presentation. The items such as slides are shown seriatim on an audience screen, and are also displayed seriatim on a presenter screen. Some of the items on the presenter screen are accompanied by respective areas for the notes, whereas the items are shown on the audience screen unaccompanied by the areas for the notes.

Abstract: In a projection arrangement for projecting an image onto a projection surface, there are provided a light source (26), a control unit (25), a light modulator (10), which is controllable by said control unit (25) in order to generate an image on the basis of predetermined image data, an optical device (11), arranged following said light modulator, for projecting said image onto the projection surface (34), a film stage (2) for holding a positive image recorded on a carrier medium, projection optics (3), arranged following the film stage (2) when projecting the positive image, and a control device (6), allowing either to direct light from the light source (26) to the light modulator (10) or to illuminate a positive image, which is held by the film stage (2), with said light. Thus, a projection arrangement is provided which can project both positive images and images generated on the basis of predetermined data onto a projection surface (34).

Abstract: A film scanning device using the same CCD light sensor for pictures of strip film and for a slide mount also comprises a body having a strip film transport path disposed there through. The transport path has a first opening in the body for inserting a developed strip film, a second opening in the body through which the developed strip film exits the body, and a third opening for inserting and pulling out a slide mount juxtaposed vertically relative to the strip film transport path.

Abstract: An image projector system includes a cold light source, a projection lens, a slide retaining unit, and a liquid crystal module. The slide retaining unit is disposed between the cold light source and the projection lens, and is adapted to retain removably a projector slide between the cold light source and the projection lens when the image projector system is operated in a slide projection mode. The liquid crystal module includes a liquid crystal panel retained removably on the slide retaining unit between the cold light source and the projection lens to permit operation of the image projector system in a liquid crystal projection mode.

Abstract: A change-over part of an image reading apparatus changes over the function of an operation part disposed on the main body of the image reading apparatus between functioning as an operation part for a connection apparatus and functioning as an operation part for the main body of the image reading apparatus. By this arrangement, it is possible for the user to perform the various kinds of processing operations at the setting place of the image reading apparatus without coming and going between the image reading apparatus and a personal computer.

Abstract: The present invention advantageously provides an enhanced event-based theater going experience. In particular, one embodiment of the present invention enables pre-recorded videos of live performances, such as concerts, to be reproduced with great realism and encourages theater attendees to act or feel more as participants and less as passive viewers. The theater optionally comprises a projection screen, a projection room, seating, a dance area, an MC (master of ceremonies) station, changeable scenic designs, special effects equipment, food services and/or a bar.

Abstract: Apparatus is described for the detailed viewing of a strip of 35 mm slide film which is enclosed in a transparent jacket. The apparatus includes a projector with a film gate which is wide enough to pass the jacket, and which projects sufficient area to include the frame number which lies under each picture frame. The apparatus enables a person to view the details of a developed roll of slide film, in its jacket, and to select particular frames for making prints or mounted slides.

Abstract: A semiconductor device having a semiconductor body includes a field effect transistor and an active transistor region with two electrode zones, one of which surrounds the other, and an island zone which is situated therebetween. These zones enclose channel regions over which there are provided gate electrodes, the first one of which surrounds the second. The gate electrodes are connected to bond pads present outside the active transistor region. The first gate electrode is interrupted at the area of the connection from the second gate electrode to a bond pad, both its ends being connected to another bond pad. Even at very high frequencies, the transistor exhibits a high gain, a high transconductance and a low input attenuation.

Abstract: A cylindrical shaped filmstrip take-up chamber is disclosed having an expandable inside cavity for receiving a varying quantity of coiled filmstrip. A cup-shaped film receiving cover closes the chamber and is both pivotally mounted near the midpoint thereof for selectively allowing access to the inside of the take-up chamber and pivotally retained at the bottom thereof allowing the cover to pivot within the confines of the chamber varying the inside volume of the take-up chamber.

Abstract: A reader-printer incorporates a fiche film projecting system and a roll film projecting system in a compact module compatible with existing main frame designs for reader-printers. Both projection systems align with a common optical axis when in operative position. Simple control means operate through a lost-motion linkage to switch a fiche lamp and condensing lens assembly and a roll beam reflecting mirror assembly in ganged relation to locate each assembly in an out-of-the-way position when the other assembly is in operative position, with the lost-motion linkage also accommodating relative vertical adjustment between these assemblies.Novel mountings permit easy total removal and replacement of the fiche beam projection lens and selective shifting of the fiche beam condenser lens to an out-of-the-way position under the control of an apertured X-Y carrier for providing enlarged openings for the wider beam presented at these locations in the roll projection mode.

Abstract: Advance shaft carries a sprocket for film engagement and carries manual knob for manually-controlled rotation. Framing shaft is rotatable with respect to projector housing and has an o-ring therebetween to serve as a drag brake. Advance shaft is detented with respect to framing shaft by means of an embracing spring. The drag brake of the framing shaft has a greater torque than the detent of the advance shaft with respect to the framing shaft.
