Abstract: A multifunctional desk lamp includes a base, a lighting body, and a light support connected to the base and the lighting body. The lighting body has an integral, one-piece structure and includes an illuminator portion for illumination and an image projection portion for projecting images. Through an integral structure design of the image projection portion and the illuminator portion, advantages of compact size and light weight are achieved. In addition to demonstrating a normal function of lighting, an additional function of projecting images is also provided. Through manual rotation of a projection gear, change of projected images can be achieved so as to make the use convenient and easy for users.

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: An image animation system having a plurality of individual image projectors focused onto a single focal area on a projection surface or medium. Angled optics, or a prism, may be used to direct the projections onto the single focal area. Individual still images are projected in a sequence to create a projected motion animation.

Abstract: A motion picture film includes a plurality of frames, with each frame formed of a first and second sub-frames. Each of the first and second sub-frames encompasses an image of a separate one of first and second sequences of successive images independent of each other. The first and second sequences of images typically undergo display one prior to the other, by projecting the film twice in succession, the first time to display the images in the first sequence, the second time to display the images in the second sequence. The film also carries two separate sets of sound tracks, each corresponding to separate one of the first and second sequences of successive images for separate playback.

Abstract: A slide mount has a first portion and a second portion. The first portion includes an interior region, an edge, and a slot extending from the interior region to the edge. A cavity is formed between the first portion and the second portion, and extends to the first edge, with a film segment in the cavity extracted therefrom by a film extraction system. The film extraction system includes a piston for disengaging a latch mechanism from the film segment. An extractor arm enters the slot to engage a second perforation in the film segment, and slidably moves within the slot to move the film segment through and out of the cavity toward a roller. The film extraction system operates with the slide mount according to a method including the steps of: extending the piston into a locking aperture in the slide mount; disengaging a latch end from a first perforation in the film segment; extending the extractor arm into the extraction slot; engaging a second perforation in the film segment with the extractor arm; and moving the extractor arm through extraction slot to move the film segment out of the cavity.
