Abstract:
An alignment mechanism has a base with a front right quadrant, a front left quadrant, a rear right quadrant, and a rear left quadrant. The base further defines a yaw axis and a pitch axis. A ball and socket linkage is located on the base at either the front right quadrant or front left quadrant at the intersection of the yaw axis and the pitch axis. A pressure plate assembly is also on the bottom surface of the base at the other of the front right quadrant and front left quadrant. A spring is in contact with one of the rear right quadrant and rear left quadrant and kitty-comer with the ball and socket linkage, with a yaw alignment surface on the other of the rear right quadrant and rear left quadrant. A pitch alignment surface is also on one of the rear right quadrant and rear left quadrant.
Abstract:
The disclosure relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and extreme ranges at stationary and moving targets.
Abstract:
An apparatus includes one or more LEDs (304) configured to be coupled to a power supply (302) and to generate illumination, such as to generate a reticle (200) in an optical scope (104). The apparatus also includes a first switch (316) coupled in series with the one or more LEDs. The first switch is configured to selectively activate and deactivate the one or more LEDs based on whether the first switch is turned on or off. The apparatus further includes a low power detector (308) configured to sense a low power condition of the power supply and to repeatedly turn the first switch on and off in response to the low power condition to cause the one or more LEDs to blink. The low power detector is configured to turn the first switch on and off at a given rate, and the given rate increases as the power supply is depleted.
Abstract:
An adjustable zero-stop turret assembly for an optical firearm scope, the turret assembly defining an axis and including: a turret housing with a cavity to receive a head portion of a main turret screw and including a wall portion defining an opening; a rotatable zero-stop element carrier including a base portion, an upper portion and a first zero-stop element coupled to the base portion; an adjustable set screw adjacent the opening; a second zero-stop element receiving the screw, a first portion of the second zero-stop element positioned within the opening, and a second portion of the second zero-stop element projecting outside the opening and into the turret-housing cavity. The second zero-stop element travels axially along the screw from a first position to a second position. In the second position, portions of the first zero-stop element and the second zero-stop element reside in a common plane perpendicular to the axis.
Abstract:
In one embodiment, the disclosure relates to a reticle for an optical sighting device, such as a riflescope, has subtension markings of varying thicknesses and scales to accommodate both stationary and moving targeting. The optical sighting device includes an objective lens system having a center axis, an eyepiece lens, and an erector lens system forming an optical system having a first focal plane and a second focal plane, the first focal plane proximate the objective lens system, and the second focal plane proximate the eyepiece lens.
Abstract:
Laser sighting systems for firearms are disclosed. The laser sighting systems are configured to project a peripheral pattern on a target the area of which is substantially representative of the spread of projectile(s) fired from the firearm.
Abstract:
A combined reflex/telescopic sight that includes a telescopic optical element train and a view window, offset from the optical element train. A transition assembly is positioned to receive light from the optical element train and the view window and has an image display, a collimating lens-set positioned to transmit light to the image display and a luminous reticle. This assembly may be placed in a first mode wherein light from the optical train travels through the collimating lenses to the image display and light from the view window is blocked. In a second mode light from the optical train is blocked and light from the luminous reticle travels through the collimating lens set and is combined with light from the view window and a resulting combined image appears at the image display. Finally an actuation assembly is adapted to permit a user to switch the transition assembly between modes.
Abstract:
A device includes can be supported on a weapon, and has a range portion (156) that specifies a range to a target, a sensor portion (201) that provides sensor information representing an orientation of the device; and a sight (10) that facilitates weapon orientation in preparation to fire the munition. The device has an electronic control portion (216) responsive to sensor information from the sensor portion (201) and a range from the range portion (156) for calculating how to hit a target with a munition, and for causing the sight (40) to present a visual indication of how to orient the weapon so that the munition will hit the target, the electronic control portion (216) terminating the presentation of the visual indication by the sight (10) in response to a lack of user activity for a selected time interval during the presentation of the visual indication.
Abstract:
Certain aspects of a firearm sight system that can include a direct view image, an infrared (IR) video image, and/or an auxiliary video image comprising auxiliary information. The firearm scope may be used as s clip-on sight system that transmits the direct view image, the infrared (IR) video image, and the auxiliary video image to a primary firearm scope. The auxiliary video image may include a bore-sighted reticle image superimposed on the direct view image or the IR video image.
