摘要： A zoom lighting device for projecting a generally rectangular illumination pattern whose size can be selectively changed. The device comprises a paraboloidal reflector and an artificial light source which cooperate to provide a collimated to nearly collimated beam of light which is circular in cross-section. The circularly-shaped light beam is intercepted by a pair of movably mounted crossed lenticular screens that are optically structured to change the circularly-shaped beam to a diverging generally rectangularly-shaped beam whose angles of divergence can be selectively changed by moving the screens relative to one another.

摘要： A multi-element photographic lens has a strongly aspheric surface formed on a strong lens element that is movable relative to the other elements along a common optical axis. The aspheric surface corrects at least the lower order aberrations contributed by the movable element thereby allowing the movement to focus the lens over a wide focus scale or object distance. Preferably, the elements are formed of plastic, the movable element is a front element, and at least one other aspheric surface is formed on a lens element.

摘要： The present invention relates to encoding and decoding of information using materials that are capable of mildly absorbing radiation over a wide range of infrared wavelengths and substantially non-absorbing in the visible wavelengths. Examples of such encoding of information are bar codes and area markings. Information is encoded in markings on a base medium by depositing or intertexturing on the base medium a material where the surface dimensions, thickness and presence of the material contain the encoded information. The encoding, as disclosed in this invention, utilizes a lower cost, more stable material than a material that is capable of highly absorbing over a range of infrared wavelengths and substantially non-absorbing in the visible wavelengths. However, since the material used in this invention is mildly absorbing in the infrared range, the signal obtained by reflecting or transmitting infrared radiation from the markings will be less distinct. Thus, inventive methods are needed to ensure that the encoded information can be decoded. Two different approaches are disclosed; (a) detecting the absorption spectrum and comparing to the known spectrum of the material in order to detect the presence and surface dimensions of the material and (b) utilizing techniques to improve the signal-to-noise such as restricting the range of wavelengths, matched filters and narrowing the bandwidth.

摘要： There is described a self-developing film unit which has a photosensitive member and an image-receiving member and wherein one outermost surface of the film unit comprises a support layer carrying a layer of a releasable material and a layer of an adhesive material. After an image is formed in the film unit by photoexposure of the photosensitive element and photographic processing of the exposed photosensitive element, the support and releasable material layer can be removed and the film unit or the image-receiving element, as the case may be, adhered to a surface for viewing of the image.
