  • Patent number: 10900747
    Abstract: Elevation turrets are used in rifles copes to adjust the point of aim of in the vertical direction. In tactical riflescopes used for precise shooting at long distance, the shooter often adjusts the elevation turret via very small movements or ‘clicks’. Each click indicates a fine adjustment step, often ½ MOA or ¼ MOA (Minute of Arc). At night or under stressful field conditions, it is difficult for the shooter to see the click markings or remember whether the turret has been turned once or twice. The present invention discloses an elevation turret that features a moving pin. The pin protrudes from the top of the turret if the turret is turned more than once. This can provide tactile feedback to the shooter and help him re-adjust his point of aim in the dark or when wearing gloves.

  • Patent number: 10809377
    Abstract: The invention relates to a calibrating system for calibrating at least one distance-measuring device. In particular, the calibrating system is suitable for almost simultaneous calibration of a plurality of filling-level measuring devices. It is characterized in that a mirror arrangement is provided, by means of which a laser tracker can determine a least one distance to at least one reflector and at least one reference distance to the at least one distance-measuring device. The calibrating system according to the invention allows both the distance to the reflector and the reference distance to be determined by a single measuring device, without the at least one reflector having to be collapsible for this purpose or the calibration having to be interrupted. The calibrating system accordingly permits more precise calibration, the calibrating system further being operable with a high degree of automation.

  • Patent number: 10802271
    Abstract: There is provided a lens device that prevents dust from entering a space in which a movable lens is moved. A movable lens is moved in the direction of an optical axis. A holding member, which extends in the direction of the optical axis, is formed at an end portion of the movable lens. A magnet is fixed to an end portion of the holding member. A hall IC is disposed in a closed storage space at a position facing the magnet. A signal, which corresponds to the position of the magnet in the direction of the optical axis, is output from the hall IC. Since the hall IC is disposed in the storage space closed by a storage box, the entry of dust, which is caused by the hall IC, into a space in which the movable lens is moved is prevented.

  • Patent number: 8928878
    Abstract: An adjusting device adjusts a reticle unit of a telescopic sight and has a rotatable setting cap and a transmission unit for converting the turning movement of the setting cap into an adjusting movement of the reticle. The turning range of the setting cap is two revolutions and arranged on the adjusting device there are two sets of scale values assigned to at least one line scale. A first set of scale values indicate adjustment values that belong to the first revolution of the setting cap and a second set of scale values indicate adjustment values that belong to the second revolution. An index ring that bears the scale values and can be turned with the setting cap or a diaphragm ring that partially covers at least one index ring is adjustable in height during the transition from the first revolution to the second revolution of the setting cap.

  • Patent number: 8879175
    Abstract: A digital camera for wild game animals includes a camera having automatic flash, focus, aperture and shutter speed and film advance functions. The camera is mounted within a camera housing adapted for outdoor installation and protection from adverse weather conditions. An electronic control circuit mounted within the camera housing is operably connected to the camera and includes a memory device and a microprocessor for storing and performing a set of programmable functions. The camera is activated by a passive infrared sensor detecting body heat of the animal or group of animals. An electromechanical device mounted within the camera housing selectively inserts an optical lens filter, such as day optical filter and a night optical filter, into an optical path of the camera in accordance with light intensity and/or a signal from a user or timer.
