Definitions

  • the invention relates to compass heading displays and, more particularly, to a method of displaying compass headings using a spectrum of colors.
  • the compass display method of the invention assigns a specific color emitted by an inexpensive tri -colored LED, coded by flashes for differentiation, to each point of the compass.
  • the invention relates to a method of displaying compass directions/headings to an observer.
  • the method of the present invention includes the steps of: assigning specific colors to at least the four primary directional points North, East, South and West of a compass; and emitting the assigned colors from a single light source (e.g., a tri-colored LED) to visually indicate a current compass heading of a person, object, vehicle or craft (e.g., boat, airplane, helicopter or drone).
  • the method may further include assigning specific colors to eight directional points of a compass, sixteen directional points of a compass, and so on.
  • the specific colors assigned to the four or more directional points of the compass may be according to a specific sequence such as decreasing wavelength or the rainbow spectrum ROYGBIV (red, orange, yellow, green, blue, indigo and violet).
  • the method may further include the step(s) of flashing the tri-colored LED sequentially between adjacent colors to reduce the number of assigned colors, thereby allowing for easier memorization of assigned compass point colors by the user.
  • the method of the present invention provides for the assignment of an emitted colored light to represent each specific compass point.
  • 8 points of a compass N, NE, E, SE, S, SW, W, NW
  • 8 points of a compass can be represented by 8 different color emissions, 16 points with 16 colors, and so on.
  • One technique to help memorize the sequence is to use the decreasing wavelength or rainbow spectrum ROYGBIV (red, orange, yellow, green, blue, indigo, violet).
  • ROYGBIV red, orange, yellow, green, blue, indigo, violet.
  • the accuracy or resolution of the system is limited by one’s ability to differentiate between the adjacent colors.
  • Another method to help reduce the memorization of many colors is to flash the LED sequentially between the adjacent colors. For example, for an 8-colored compass where N is red, NE is orange, and E is yellow, a certain system is designed to flash its directional color 1 second on and 1 second off. When pointing N, the LED would flash red on for 1 second, then off for the next 1 second. The on/off flashing cycle of red (North) and off remains until the direction changes. Similarly for other colors/directions. To represent NNW, the LED would flash red for a half second, followed by a half second violet flash, then 1 second off; thus, sequential dual color flash. ENE would be orange for a half second, yellow for a half second, and then off for one second. The user now would only need to memorize 8 color positions while having codes to understand the 16 points of the compass.
  • a tri-colored LED is a single packaged LED which contains three individual primary colored LEDs (one red, one green, one blue).
  • the intensity of each LED can be independently modulated and mixed to create (i.e., emit) any color our eyes see. With all colors at maximum intensity, the color will be white.
  • individual RGB LEDs mounted closely on a panel can been used.
  • the application of the compass display method of the present invention can also be used to supplement the anti-collision or navigation light system used in aviation, marine, and off-road vehicles. This would allow a distant observer to see an incoming object’s trajectory. This additional visual data can help to determine the path of the vehicle/object for collision avoidance.
  • the compass colored light can be flashed or strobed at different rates to differentiate itself from existing navigation lights. For example, on a boat or plane, there are basically three navigation lights: red for left (port) side, green for right (starboard) side, and white for the stem or aft light.
  • the colored compass light can be designed to replace or compliment the stern/aft light.
  • the RGB LEDs can be all-on (to represent white spectrum) as the white stem light. Perhaps every few seconds, the device would strobe in a specific color for the direction of travel of the vehicle/craft and then turn back to white. This will allow other pilots in the area to easily and quickly determine the direction of travel of another vehicle/craft.
  • the compass display method of the present invention can also be incorporated on helicopters, UAVs (unmanned aerial vehicle), or drones. Due to the omnidirectional nature of some drones, traditional aviation navigation lights (left, right, front, and aft) are not applicable. An RGB LED may be the optimal navigation light for drones due to its size and shape. Accelerometers and gyroscopes can be used in conjunction with the compass to signal the direction of travel instead of pointing direction.
  • the application of the compass display method of the present invention can be applied to portable navigation devices.
  • the simplistic display method can provide significant cost, size, and reliability advantage.
  • a product may have only an optical light window port while the active electronics of the compass can be fully sealed from the harsh environment, such as water and dust.
  • the device’s external -facing lens can transmit light to other locations by ways of reflective mirrors, fiber optics, acrylic light rod/pipe, optical gel/glue, or plexi-glass materials.
  • the directional compass display method of the present invention is ideal for swimming googles, scuba diving masks, virtual/augmented reality head-mounted displays, binoculars, smart-glasses, pens, pointers, and also vehicle dashboard displays.
  • the compass colored light can be displayed as a point source from the LED lens or as background lighting.
  • the optical display can be a part of the product casing itself, such as optically clear plexi glass/plastic, or clear silicone rubber casing.
  • the compass display method of the present invention can be employed in dashboard applications for any moving vehicles. It can help to de-clutter dashboard of graphics, texts, and numbers by using a glowing colored background to represent the direction of travel.
  • the directional compass display method of the present invention can also be incorporated in a standalone product such as a “compass puck,” a rounded product with a dome top for the optical LED and a sticky or magnetic bottom.
  • the compass puck (or similar standalone device) is a portable battery-powered electronic compass which you can mount anywhere to give you direction of travel or heading. Its useful applications are open to the creativity of the users. For example, placing several units at various locations on the deck of a sailboat will help the crew to confirm the captain’s maneuvering intentions. It can also be mounted on off road vehicles, mountain bicycles, kayaks, etc.

Abstract

Un procédé d'affichage de caps au compas comprend les étapes consistant : à attribuer des couleurs spécifiques au moins aux quatre points cardinaux nord, est, sud et ouest d'un compas ; et à émettre les couleurs attribuées à partir d'une source lumineuse unique (par ex. d'une DEL tricolore) pour indiquer visuellement un cap actuel au compas ou une orientation actuelle d'une personne, d'un objet, d'un véhicule ou d'un engin (par ex. d'un bateau, d'un avion, d'un hélicoptère ou d'un drone). Le procédé peut en outre consister à utiliser des flashs codés d'une ou de plusieurs couleurs pour indiquer des aires de vent avec limitation du nombre de couleurs attribuées, pour faciliter la mémorisation.
