Abstract: The method and system embeds digital meta-data into an original image in such a way that the meta-data can be completely removed at a later time to allow loss less recovery of the original image. The loss less recovery of the original image allows for a digital signature of the image to be embedded in the image itself and later recovered and used to verify the authenticity of a received image.

Abstract: An improved method for injection molding fine particulate inorganic materials that first spray dries a fine particulate inorganic material and then mixes the dried particulate inorganic material with a binder system to form a compounded material. The compounded material is then injected, at a low pressure into a mold to form a green part. The green part is then debinded to remove most of the binder system and the debinded green part is then sintered to form the final molded part.

Abstract: A media for restricting the copying of a document utilizing one or more microdots that are embedded in said document for providing a non-visual, but machine detectable mark or marks. The detected means for detecting the presence of one or more microdots in said document inhibits a copy machine from copying the document.

Abstract: A color-negative photographic print medium for restricting the copying of an image in the medium utilizing a pattern of removable color-subtractive microdots depth-wise positioned anywhere within a transparent protective overcoat and a support layer which supports at least one image-forming layer is disclosed. The microdots are undetectable by the unaided eye, but detectable by copying machines programmed to prevent copying when microdots are detected.

Abstract: Several different methods alone or in combination can be used to reduce image jump or stutter. The image plane on which the original image is taken can be mechanically or electronically rotated about a point of rotation in the scene. The number of original images which are viewed could be increased by interpolation. The subtended viewing angle of the viewpoints can be reduced and viewpoints within the subtended viewing angle can be increased by interpolation. Reduced subtended viewing angle images can be created for each eye. The depth of focus of the images can be changed by identifying the images that jump and blurring the images outside the area of interest. The original images can be processed to move the image plane further back from the objects in the scene. Some of the images ordinarily existing between the right and left eye perspectives can be eliminated. The objects in the background of the scene being photographed can be identified and shifted forward in the scene.

Abstract: A piezoelectric motor system is formed with a piezoelectric motor incorporating an element that is physically displaced as a function of an applied voltage resulting in the generation of a back electromotive force. The system incorporates a controller having an output connected to the piezoelectric motor. The controller receives a direction signal indicating the desired drive direction of the piezoelectric motor and a velocity signal indicating the desired velocity of the piezoelectric motor. The controller provides a drive voltage for driving the piezoelectric motor in the desired drive direction. An electrical equivalent circuit that mirrors the electrical characteristics of the piezoelectric motor is connected to receive the drive voltage from the controller. A comparator provides a difference signal indicative of the difference in voltage developed across the piezoelectric motor and the voltage developed across the electrical equivalent circuit.

Abstract: An improved microminiature radiation reflector is formed in a silicon support body with a fabricated cantilever member extending over a cavity that has been etched in the support body. The cantilever member has a reflection surface for reflecting incident radiation to a first position when the cantilever member is not deflected. An electromagnet is formed in the silicon support body adjacent the free end of the cantilever member for deflecting the cantilever member into the cavity of the support body so as to cause incident radiation to be reflected to a second position. An array of radiation reflectors is also disclosed for forming images from electrical signals applied to the electromagnets of selected ones of the radiation reflectors as a function of the position of their reflected radiation in the to be formed image.

Abstract: A method of identifying business forms that uses contour polygons constructed from linear line segments. Wherein contour polygons are derived from a windowed raster scan of the forms' image. Each of the contour polygons is examined to determine if it represents a text component or a graphic component. All text contour polygons and graphic contour polygons are grouped and profiled. The accumulated profiles are compared against a library of stored profiles of known forms so as to determine a best match thereby identifying the unknown form.

Abstract: A shutter is disclosed having a shutter blade frame comprised of two spaced apart rails, each rail incorporating at least one magnet section. Individual pairs of electromagnets are positioned for movement along the rails. At least one shutter blade, having an opening defined thereby, is connected to a pair of electromagnets for movement along the rails from a rest position to an open position. Application of current to the electromagnets causes the at least one shutter blade to travel along the rails causing an alignment of the defined opening with a selected light path to cause an exposure generally of an image sensor such as film. Springs are positioned on the shutter frame for urging the at least one shutter blade to the rest position.

Abstract: Disclosed is a copy protection method for identifying copied images that have been captured or generated in electronic form. The method generates information in electronic form for causing the printing of copy restrictive information as a plurality of contiguous pixels, of substantially yellow color onto the hard copy. The visibility of the yellow pixels is very low until a cyan illumination is applied to the protected image then the copy restrictive information becomes highly visible.

Abstract: A printer device for lenticular photographic images easily transforms electronic image files into photographic hard copy. The printer device includes a cathode ray tube screen and a projection lens. A filter wheel may be used for inserting optical filters into the optical path of the projection lens. A lenticular photographic print assemblage is aligned and affixed at the focal plane of the projection lens. The lens and the image on the cathode ray tube screen are then moved in differential amounts in the direction parallel to the plane of the aligning and affixing process, and normal to the axis of the lenticules on the lenticular photographic print assemblage.

Abstract: A system and method for creating three-dimensional or depth image font text characters using graphic three-dimensional object creation techniques and graphics processors. The text characters can be represented as set descriptions of the characters. The text characters can also be represented as a three-dimensional geometric model including polygons constructed from vertices defined by three-dimensional coordinates. The representations are stored in a font storage and when a user specifies the text characters to be used in a depth image along with the font to be used for the text characters, the geometric representations of the characters are retrieved. If stored as a set, the set is converted into a geometric plot. Appropriate scaling and surface texturing operations are performed as designated by the user to create three-dimensional text character graphic objects.

Abstract: A method of encoding and decoding a transaction card with a block of image data digitally representing the features of a digital portrait of an authorized transaction card user is disclosed along with apparatus for performing the method. The encoding method partitions the digital portrait of the transaction card user into feature blocks. Each feature block is compared against a library of like feature blocks to determine the best match with a pair of library feature blocks. The library's feature blocks are derived from a plurality of portraits taken from the general population. Each library feature block is represented (addressed for access) by a code-vector in a codebook.

Abstract: A system and method in which a size of a pixel used to print lenticular depth images is changed to remove overlap in the slow scan print direction. A space adjustment of the space between scan lines can also be performed to remove pixel overlap. The pixel can also be elongated in the fast scan direction reducing fast scan resolution. An elongated pixel can be combined with skip space adjustment to remove pixel overlap. Printing the image lines in the fast scan or dot movement direction improves image quality. The print resolution in the fast scan direction can be reduced by increasing the printing rate compared to the data rate of the supplied image data, thereby cloning pixels in the fast scan direction, while maintaining a normal slow scan speed to normally print lines. Combinations of the above approaches to directional printing, removing slow scan pixel overlap and reducing file size can be accomplished.
