Nonrolling Fluid Spreading Apparatus Patents (Class 396/586)
  • Patent number: 9582039
    Abstract: The invention relates to a touch screen protector for a hand held electronic device having a front face that includes a touch screen portion and a non-functional band. The touch screen protector of the invention comprises a plastic film having front and back sides, an outer perimeter that corresponds to that of the device, and a transparent window; a spacer provided along the outer perimeter of the plastic film surrounding the transparent window, having a thickness sufficient to space the plastic film near but not in contact with the touch screen portion; an exposed adhesive for removably mounting the protector upon the outer perimeter of the front face to form an enclosed air space between the transparent window of the plastic film, the spacer and the touch screen portion of the device; and a joining adhesive for adhering the spacer to the back side of the plastic film.

  • Patent number: 9283731
    Abstract: The invention relates to a touch screen protector for a hand held electronic device having a front face that includes a touch screen portion and a non-functional band. The touch screen protector of the invention comprises a film having front and back sides, an outer perimeter that corresponds to that of the device, and a transparent window; an exposed adhesive or adhesive/spacer provided along the outer perimeter of the film surrounding the transparent window, and multiple dots arranged in a prescribed pitch and present on the back side of the film at a density which is sufficiently high to reduce interference patterns when the transparent window of the protector is pressed against the touch screen portion for operation of the electronic device.

  • Patent number: 9128545
    Abstract: A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

  • Patent number: 5802402
    Abstract: A film cassette may be used for housing film units of the self-developing type, each having a photosensitive area, a pod of processing fluid, and a leading edge. The film cassette may be used in a film assemblage, camera back, or imaging device having either a straight or a curvilinear film path configuration. One such film cassette includes: a chamber defined by forward and rear walls, a pair of side walls, and leading and trailing end walls; means for resiliently supporting the film units within the chamber; first spread control means for use when the imaging device has a straight film path configuration, the first spread control means including at least one projection formed on an interior surface of the forward wall; and second spread control means for use when the imaging device has a curvilinear film path configuration, the second spread control means including at least one projection formed on a bottom surface of the rear wall.
