Abstract: A compact, rigid camera for use with self-developing film utilizes a prism element having an exit face overlying the film and which is both reflective and transmissive to fold the optical path of useful light rays between an objective lens and a film plane in a relatively small volume. A prism entrance face is oriented with respect to the reflective/transmissive exit face so that entering light is totally internally reflected at the exit face to at least two other faces of the prism which are reflective and oriented to return the light to the exit face substantially along its perpendicular. The exit face is coextensive with the film plane so that the reflected light transmitted through the exit face exposes the film. In one form the exit face of the prism is planar and closely spaced from the film plane. In another form the exit face has two mutually inclined planar surfaces, each of which internally reflects one image beam and transmits another beam internally reflected from the other face. In the latter form an auxiliary emergent prism is interposed between the exit face reflective/transmissive surfaces and the film plane.

Abstract: Optical elements shaped in accordance with preferred analytic functions which permit the elements to be relatively rotated about one or more pivots decentered with respect to an optical axis to simulate the dioptric action of a well corrected rotational lens element of variable power that can be used to maintain focal setting over a large range of object distances. The optical elements can be used in pairs, singly with mirror images of themselves, or they can be incorporated in more elaborate systems to provide focusing action.

Abstract: Wide angle optical objectives for use in aerial mapping cameras to provide improved resolving power and improved contrast rendition derived from the pattern of glass types and lens data employed. The outermost elements are weakly positive menisci to produce an initial convergence of rays before the mating negative elements are introduced thereby keeping the physical length of the system within modest proportions. Strong negative elements lying outside of centrally located strong positive elements provide favorable illumination over a wide angle field. Wafer elements near the center of the system serve to minimize chromatic astigmatism and to reduce the actual sagittal depth of the aspherics. Wafers of high index flint glass are located next to the central stop in order to obtain good chromatic spherical correction in the tangential rays over the field.

Abstract: A shadow hardware system and method is provided. The shadow hardware system provides an interface between an access device and shadowed devices. Shadowed devices are devices that the shadow hardware system provides an interface to the access device although the shadowed device may not actually be present or available to the access device, such as implementing a disk drive as flash memory. The access device, such as a host processor, issues requests to a disk drive and the shadow hardware system converts the requests to requests suitable for the flash memory. A shadow remapper redirects the requests to shadow registers and notifies the shadow controller of the pending request. The shadow controller accesses the shadow registers and modifies the registers (if necessary) before forwarding the registers to the actual hardware devices. Any suitable device may be shadowed.

Abstract: A compact substantially afocal lens comprising two components each including two elements adapted for use as a magnifying attachment for an objective with an internal stop. Compactness in an afocal lens of good performance is obtained by the use of a strongly curved first surface followed by other strongly curved surfaces, by the choice of alternating high and low indices of refraction for the successive negative and positive elements, respectively, and by correcting the lens less well for longitudinal color and distortion than for the other aberrations.

Abstract: A lens system for a folding reflex camera is provided. The system includes: (a) a first group on the object side of the system's stop which (i) has a positive dioptric power, (ii) includes an aspheric surface, and (iii) has a concave surface adjacent to the stop; and (b) a second group on the image side of the stop consisting of either a single positive component or the combination of a single positive component and one or more focusing elements. The system includes at least two elements made of materials differing in dispersive powers where at least one of the elements is of plastic. The system can comprise just two plastic elements and even with such a simple configuration achieves excellent optical performance including a relatively flat field, relatively low distortion, and at least partial correction for lateral chromatic aberration.

Abstract: A method and apparatus for determining the correct temperature of a heated coil of sheet material and for using said measurement to control a heat treating furnace. The method includes providing a spot of heat resistant material having a known and constant emissivity that is substantially unity on an uneven edge of the coil, the material of the spot remaining on peaks of the uneven edge. The constant emissivity of the spot is independent of that of the edge, the emissivity of which changes and indicates a temperature is substantially different from the true temperature of the edge. The coil is heated and the spot emits infrared energy in an amount that is substantially representative of the correct temperature of the coil and edge. This infrared energy is sensed by an infrared detector aimed at the spot, the output of the energy being indicative of the true temperature of the edge and of the coil mass after it attains the temperature of the edge.

Abstract: A compact convertible photographic objective that is separable into two working components consisting of a front substantially afocal component that can be rotated or translated laterally into or away from a coaxial position with a rear component which normally is fixed in position on an assigned optical axis. Movement of the front component into coaxial alignment with the rear component increases the focal length of the combination so that the two components can be used for telephoto purposes.
