  • Patent number: 10791275
    Abstract: Systems and methods for measuring the distance to a target object and acquiring three-dimensional coordinates, scale information, and point-to-point distance information for that target object in an environment using a remotely operated cable-suspended platform. The system uses on-board sensors and processing techniques to provide discrete or continuous measurements of the distances between points on a target object or the scale of the target object. The addition of on-board three-dimensional measurement capabilities to cable-suspended platforms enables these systems to acquire three-dimensional position data defined in the coordinate system of the environment, determine distances between objects or between points on the same object. The system can also be used to determine the scale factors of items in images captured by a camera carried by the cable-suspended platform, in the course of performing metrology-related tasks.

  • Patent number: 10042154
    Abstract: A system and method for introducing a display image into an afocal optics device through an objective lens and without using a beamsplitter. A display device emits the image in a first direction, a focusing lens focuses the image, and a first reflector redirects the image in a second direction. A second reflector redirects the image through a periphery of the lens so that both the image and gathered light received from a target appears on the same focal plane such that the image appears to a user to be located between the lens and the target. The periphery of the objective lens may be a distance which is no more than 30% of a diameter of the lens from an edge of the lens. If the optics device is a rifle scope, the image may communicate such relevant information as range, inclination, wind direction or velocity, or temperature.

  • Publication number: 20140160475
    Abstract: A weapon sighting system for gathering ambient or generated light and projecting a fixed or adjustable ballistic reticule image for targeting. The system includes a partially reflective, zero parallax, optical lens assembly, an illuminating reticule projection component, and an adjustable bracket fixed to the weapon being sighted. The bracket supports the lens assembly at one end and the projection component at an opposing end. The projection component is aligned to project a light image onto the lens assembly to be reflected back into the target sightline. The projection component gathers ambient (or generated) light through polymer acrylic solid materials and/or fiber optics, and directs the light through a fixed or adjustable mask. The movement of the weapon effects a corresponding movement in the angle of reflection through the optics of the sighting system. An adjustable mask allows the projected image to change to accommodate near and distant targets.

  • Patent number: 6516551
    Abstract: An optical sight for a photocamera viewfinder or for an aiming device of a firearm comprises a combination of a light emitting diode (LED) with a plurality of reticle patterns applied onto the surface of the LED and selectively illuminated by connecting various portions of the reticle patterns to the source of electric power supply. The switching from one reticle pattern to another is carried out electrically without the use of moving parts of the reticles or reticle images. This ensures high accuracy in positioning of reticle elements with regard to each other, e.g., with regard to the front sight center of the partially transparent mirror, and hence, with regard to the ballistic trajectory of the bullet.

  • Patent number: 5594584
    Abstract: A dot sighting device comprises a lens-shaped transparent objective element with convex and concave surfaces, the convex surface extending outwardly toward a target and the concave surface extending toward a user's eye. The concave surface has a first center of curvature lying on a baseline parallel to an optical axis of the element extending from a center of the element to the user's eye. The concave surface has a first radius from the first center of curvature to a center of the concave surface. The baseline and the first radius subtends an angle .theta. with each other. The convex surface has a second center of curvature positioned eccentrically from the first center of curvature located in a plane containing the baseline and the first radius. The convex surface has a second radius extending from the second center of curvature to a center of the convex surface. A light source is disposed behind the element and directed toward the center of the concave surface such that a light flux makes an angle .theta.

  • Patent number: 5577326
    Abstract: A red dot optical sight apparatus for a firearm having an optical element and a light emitting diode disposed at the focal point of the optical element, in which at least the optical element is pivotal between a lowered, inoperative position and a raised, operative position. The apparatus further includes spring biasing to assure that the optical element is in a precisely defined position when pivoted to the raised, operative position.

  • Patent number: 5493450
    Abstract: An electronic light dot reticle sight (10) for a firearm has a concave surface lens (22) in a tubular lens housing (11) and an external LED (25) connected via a fiber optic (26) to generate a light point image viewable ahead of the concave surface. A tubular circuitry housing (32) joins lens housing (11) at right angles and has a light adjustment knob (58) which turns a printed circuit disk (42) against a contact (54) on an internal shoulder (39) to select a resistor connection (38, 46) to a spring-loaded common battery contact (49). A spring-loaded pin (73), passing through a recoil bar (70) having an arcuate projection (93) that fits within an arcuate recess (94), provides a shock-resistant connection between lens housing (11) and the firearm. Adjustment screws (31, 94) act at one end of bar (70) to set windage and elevation about the pivot.

  • Patent number: 5440387
    Abstract: A parallax free sight has an optical element, preferably arranged at one end of an elongated light channel. A concave side thereof is parabolically shaped and provided with a partially reflecting layer, in the focal point of which is arranged a light emitting means. The element is moulded in one piece of a plastic material, preferably polycarbonate, and an opposite, convex side is elliptically or hyperbolically shaped, such that any light beam hitting it from the outside continues straight through it with minimal deviation.
