  • Publication number: 20120036749
    Abstract: A nautical navigation aid comprising a photoluminescent element and a light wave re-directing means for improved photoluminescent qualities used to enhance the safety of nautical travelers on waterways in conditions where visibility is limited. The navigation aid sign has a first rigid sheet member having an upper surface, a lower surface and a peripheral edge, a second rigid sheet member having an upper surface and a lower surface extending outward from the peripheral edge of the first rigid sheet member at a predetermined angle to a predetermined length, thereby defining an angled collar of the first rigid sheet member sized and configured to redirect light waves emanating from a light source, and a luminescent layer. It is envisioned that an embodiment of the present invention might also include a means for retrofitting existing nautical navigation aids with a photoluminescent element and a light wave re-directing means for improved photoluminescent qualities.

  • Publication number: 20120001406
    Abstract: Methods for illuminating (backlighting) an emblem on a steering wheel cover or other indicia within a vehicle include the use of a material that is self-illuminated without electricity. This can involve using self-luminous microspheres or phosphorescent additive materials. Such materials will not be illuminated during the daylight, but when night falls (or other periods of relative darkness), they will illuminate the emblem or other indicia. These materials may be added directly to the plastic that is used to make the emblem.

  • Publication number: 20110298604
    Abstract: A protective advertisement cover for barriers is disclosed. The cover functions as both a protective cover and as an advertising substrate. The cover provides damage control and protection to anything coming into proximal contact with the bather while an advertisement component makes the barrier more noticeable and therefore more avoidable to customers, pedestrians, workers, trespassers and the like. The disclosed cover includes a shock absorbing component layer configured to absorb shock and substantially return to its original form after impact from a third object. The cover also includes an advertisement component layer that may be disparate from the underlayment shock absorbing layer or imprinted directly thereon. Additionally, the disclosed protective advertisement cover includes a transparent and deformable component layer which may shield the advertisement from weather and graffiti and contribute to protecting motor vehicle doors and body parts from damage by a bather.

  • Publication number: 20110209367
    Abstract: A light emitting sign comprising a plurality of blue LEDs operable to generate blue excitation light and a light emitting display surface comprising a light transmissive substrate and at least one phosphor overlaying at least a portion of one face of the substrate. The phosphor is configured to absorb at least a portion of the blue light generated by the LEDs and, in response, to emit light of a selected color other than blue. Regions of the display surface intended to generate blue light do not include the phosphor.

  • Publication number: 20110167689
    Abstract: An identification patch adapted to be attached to an object for its identification and method. The patch comprises a first area of material radiating within a first infrared band detectable by a first device operating in said first infrared band and a second area of material radiating within a second infrared band detectable by a second device operating in said second infrared band. The combination of the first and second areas of material forms a discernable pattern detectable when using a selected one of said devices yet covert to the naked eye. A covert identification patch for a vehicle having a roof and method. The patch comprises a frame having a first surface and a second surface the frame dimensioned and having an external characteristic to approximate that of a sunroof, a first material on the first surface wherein the first material radiates electromagnetic radiation within a first band undetectable to the naked eye, and an adhesive for attaching the frame to the roof.

  • Patent number: 7937865
    Abstract: A light emitting sign comprising a light emitting display surface including at least one phosphor, and at least one radiation source configured to irradiate the display surface with excitation energy such that the phosphor emits light of a selected color. The sign further comprises a filter which is substantially transparent to light emitted by the display surface, filtering other colors of light. The display surface may be configured into a shape of a character, a symbol, or a device. Alternatively, a mask having at least one window substantially transparent to the emitted light and/or at least one light blocking region may be provided in which the window and/or light blocking region define a character, a symbol, or a device.
