A radiographic image detector assembly is mounted within the cavity for converting a radiographic image to an electronic radiographic image. The detector assembly includes a detector array mounted on a stiffener. A shock absorbing elastomer assembly is located within the cavity for absorbing shock to the detector array/stiffener in directions perpendicular to and parallel to the detector array/stiffener.

摘要： A printing apparatus 10 exposes an image onto a photosensitive medium 14, having a printhead 20 with a linear array of exposure sources 40, each exposure source 12 operable at a variable intensity. A shuttle mechanism 16 moves the printhead 20 over the photosensitive medium 14 in a reciprocating motion between one end of a carriage assembly 72 and the other. An encoder 38 is coupled to the shuttle mechanism (16) for providing an index encoder pulse 60 at each of a plurality of increments of position of the shuttle mechanism 16 along the carriage assembly 72. Exposure control logic calculates a shuttle velocity according to index signal timing and adjusts the variable intensity of each exposure source 12 according to the shuttle velocity.

摘要： A fundus camera (10) obtains a retinal image using a light source (62), a ring aperture (58) conjugate to the cornea, and a first aperture (54) conjugate to the iris. An apertured mirror (52) redirects the ring illumination toward the eye. An objective lens (50) between the apertured mirror (52) and the eye has an entrance pupil between the iris and the cornea of the eye. The objective lens (50) directs the ring illumination into the pupil of the eye and directs a reflected image-bearing light from the retina through the apertured mirror (52). A second aperture (64), conjugate to a plane between the cornea and the iris of the eye, forms an aperture stop for the reflected image-bearing light. A third aperture (68) is conjugate to the cornea for blocking light reflected. A sensor (70) provides an image of the retina.

摘要： An apparatus for recording an image onto a sheet medium (12) has an entrance nip (14) for transporting the sheet medium (12) into an image recording section (20). A write head (56) records onto a portion of the sheet medium (12) between the entrance nip (14) and exit nip (24). The exit nip (24) is formed by a drive roller (26) paired with a corresponding exit pressure roller (28). A motor (60) provides rotary motion to either the entrance drive roller (16) or the exit drive roller (26). A coupling apparatus (54) has a coupling roller (36) and a loading mechanism providing a loading force to nest the coupling roller (36) into continuous rotational contact against the entrance and exit drive rollers (16,26), whereby rotation is transferred between the exit drive roller (26) and the entrance drive roller (16).

摘要： A method of sensing the pitch or relative location of a lenticular lens on a sheet of transparent lenticular material of the type having a repeating pattern of cylindrical lenses on one side and a flat opposite side, comprising the steps of: forming a beam of light; focusing the beam of light into a spot smaller than the pitch of the cylindrical lenses onto the lenticular material; moving the lenticular material relative to the beam in a direction perpendicular to the axes of the cylindrical lenses to modulate the angle of reflection or refraction of the beam of light; and sensing the position of the modulated beam of light to determine the pitch or relative location of lenticular material to the focused spot.
