    摘要: A sensory aid system for visually handicapped persons. The system provides a magnified image of graphical material, such as text. The system includes an image sensor which may include a lens assembly and photodiode detector array. The image sensor is coupled to a display array, with each detector array element having a one-to-one correspondence with one (or a group of) display array elements. The display array may be adjusted electronically to provide any degree of magnification simply by changing the number of elements in the array driven by the signal information. The display array elements may be red light emitting diodes (LED's). In this form, the present invention provides a magnified brightly illuminated red image of the black areas of print against a black, or dark, background, instead of the conventional text format of black print (information) on white paper (noise).

    摘要: A coin wrapper for wrapping coins comprises a coin input region for receiving the coins, a coin queuing mechanism for receiving the coins from the coin input region and moving each of the coins away from the coin input region, a coin stacking region for receiving coins from the coin queuing mechanism and stacking the coins on at least one stacking element to created a coin stack, and a coin wrapping region for receiving the coin stack on the stacking element from the coin stacking region. The coin wrapping region includes a plurality of rollers for rotating the coin stack and a paper feed mechanism for introducing paper to be wrapped around the coin stack.

    摘要: An optical apparatus for measuring angular or linear displacements. The apparatus comprises a single planar element having on its surface a pattern of sectors characterized by alternating optical transmission coefficients. An optical system superimposes a real image of a portion of the pattern upon that portion of the pattern itself. This image moves in the direction opposite to the planar element, so that as the element moves, the interaction of the sectors of the image with the sectors themselves creates alternating light and dark areas as a result of shuttering or interference effects. A light sensor monitors these light and dark areas thereby providing a measure of the displacement of the planar element.
