Abstract: The present invention provides an improved lenticular display unit for advertising, information, or decoration. The unit comprises means for maintaining the required spatial relationship between the indicia carrier, on which the information to be displayed is contained, and the lenticular panel containing the lenses used to display the information. In some embodiments, the unit employs spring means for maintaining the required spatial relationship, which is maintaining the required distance between the indicia carrier on which the information to be displayed is contained, and the lenticular panel containing the lenses used to display the information.

Abstract: Aiming device for firearms that comprises a retro reflective lenticular element, which collects and reflects ambient light beams and/or beams originated from a light source, and which is seen by the shooter as having a first bright color when the aim line has a desired orientation and having a second color, or no color, when the aim line does not have the desired orientation.

Abstract: The present invention discloses a method for displaying individually on a plurality of keys of a keyboard or keypad two or more indicia representing two or more functions performed by each key. The keys are characterized in that each of the two or more indicia is provided on the key in a plurality of separated portions. The portions being positioned in a spaced positioned relationship with one another, so as not to be physically closely juxtaposed. When viewed at a predetermined angle all parts of the indicia are optically juxtaposed to create the entire indicia.

Abstract: The invention provides a display unit for displaying two or more consecutively changing images, the unit including a curved lenticular panel having front and rear faces; a displaceable, lightweight, image-carrying film spread out along the rear face; an electric drive coupled to the film for periodically displacing the film across the lenses of the panel, and guide means facilitating the smooth reciprocating movement of the film.

Abstract: An automatic vending machine having a front door with at least one opening. A translucent image carrier bears two or more images cut into information strips and arranged on the image carrier by an intercalation process. The image carrier is mounted behind an array of cylindrical lenses. At least one light source is disposed behind the image carrier. A relative, linearly reciprocating movement is produced between the array of lenses and the image carrier in a direction perpendicular to an axial extent of the lenses. In the course of the relative movement, the array of cylindrical lenses provides, in succession enlarged views of the images borne by the image carrier, thereby producing an animated effect.

Abstract: A computerized method for creating a multi-image print for use with a dynamic display based on the relative periodic displacement of the multi-image print relative to a lenticular screen includes inputting, into a computer, data relating to a dynamic display and at least two basic images. The digital data of the images is used to set size and resolution of the images, thereby creating basic documents. The visual requirements of the basic documents including resolution, exposure time within a display cycle, and graphic characteristics are then determined. Each of the basic documents is divided into information units and is interlaced into a single document. The single document is processed to satisfy the data requirements, and the complex document is printed on a sheet to produce a multi-image print so that basic images will be alternatively displayed when the print is displaced relative to a lenticular screen.

Abstract: An indicia carrier film suitable for producing consecutively changing images in harmonious fashion. The indicia carrier includes a display unit housing provided with at least one panel formed from an array of linear lenses, a displaceable indicia carrier film which is disposed within the housing at a distance from the rear face of the lenticular panel equaling the focal length of the lenses, and a drive means for periodically displacing the indicia carrier relative to the lenses. The ratio of film weight to surface area is greater than 1:100 gm/cm2. The total weight of the film is not greater than 10 gm for an indicia carrier of approximate A4 dimensions (17×29.5 cm). The modulus of elasticity is of at least 600 Mpa.

Abstract: The invention provides a self-powered timepiece including a housing; a lenticular panel mounted in the housing; a high-efficiency, battery-powered drive means having a cam; time-indicating means movable by the drive means, and a lightweight indicia carrier disposed inside the housing in close proximity to the panel, the carrier being displaceable by the cam in relation to the panel. The invention further provides a self-powered timepiece including a housing; a high-efficiency, battery-powered drive means; a lenticular panel coupled to the drive means; time-indicating means movable by the drive means, and a lightweight indicia carrier disposed inside the housing in close proximity to the panel, the panel being displaceable by the drive means in relation to the indicia carrier.

Abstract: The invention provides an automatic vending machine having a front door, including at least one window-like opening in the front door; a panel consisting of an array of cylindrical lenses located and fixedly mounted in the window-like opening; a translucent image carrier bearing a computer-processed image of at least one object to be shown in dynamic display, the image carrier being mounted behind the array of lenses; at least one light source disposed behind the image-carrying panel, and means for producing a relative, linearly reciprocating movement between the array of lenses and the image carrier in a direction perpendicular to the axial extent of the lenses; wherein, in the course of the relative movement, the array of cylindrical lenses provides a succession of compound, virtual, enlarged images, producing an animated effect.
