Abstract: An optical device has a housing and an adjustment ring rotatably disposed about the housing. The adjustment ring defines a channel. A lever selectively engages with the channel and may be used to rotate the adjustment ring.

Abstract: An optical device housing has a post rotatably extending therefrom and a sleeve fixedly extending therefrom. The sleeve is disposed around the post. A knob is connected to the post. A clutch mechanism includes: a friction element movably engaged with the sleeve; a friction surface; and an adjustment element engaged with the friction element and rotatable relative to the optical device housing and the knob housing. Rotation of the adjustment element selectively engages the friction surface with the interior surface.

Abstract: An optical device housing has a post rotatably extending therefrom and a sleeve fixedly extending therefrom. The sleeve is disposed about the post and a knob is connected to the post. A nut rotatably engages with the sleeve and is configured to rotate with the knob. An adjustment screw is threadably engaged with the nut and engages with the knob so as to rotate with the knob. Rotation of the adjustment screw about a screw axis increases a frictional resistance between the nut and the sleeve.

Abstract: A method of sighting a target includes receiving an initial condition of an optical device. The initial condition includes a size of a ranging element and a range associated with the size of the ranging element. The method further includes receiving a ballistic information and receiving an image from an imaging sensor. At least a portion of the image is displayed on a display. The ranging element is overlaid on the displayed portion of the image. A first zoom input is received to set a first zoom value that corresponds to a first distance from the optical device. The method also includes determining a first projectile position based on the first distance and the ballistic information.

Abstract: An apparatus includes a mounting ring and a collar. The mounting ring includes an upper ring portion and a lower ring portion secured to the upper ring portion. Each of the upper ring portion and the lower ring portion has an inner ring surface defined by a plurality of radii. The collar is disposed in the mounting ring and includes a substantially cylindrical outer collar surface. The substantially cylindrical outer collar surface is disposed proximate the inner ring surface.

Abstract: An optical device includes a housing containing a plurality of lenses. At least one of those lenses includes a reticle. An optical device and a processor are also located in the housing. A wind speed sensor is mounted to the housing and configured to send a wind speed signal corresponding to a wind speed to the processor. The processor calculates a wind speed based at least in part on the wind speed signal, and wherein the processor sends an output signal corresponding to the calculated wind speed to the output device.

Abstract: Embodiments of the present invention relate to a mounting assembly for mounting a reticle type sight on a long gun. The mounting assembly includes a mounting plate for securing the mounting assembly to a rearward portion of a long gun, and a mounting block coupled to a top portion of the mounting plate. The mounting plate has one or more connection elements to enable a reticle type sight to be coupled to the mounting block.

Abstract: A synthetic erector lens mount for use in a rifle scope or similar optical instrument incorporating glides, or rails, which ride on the inner surface of the guide tube. Biasing fingers, or tabs, incorporate raised bulges, or angle radially outward from the body of the mount, or both, so that they push outward on the walls of the guide tube, pushing the mount against the glides. Preferably the mount incorporates a recess on the inner wall of the mount for capturing a nut or other fastener, a hole through the wall of the mount, and a flattened area of the outer surface of the mount, parallel to the recess and aligned with the hole, for removably attaching a guide sleeve which engages the slots in the guide tube and cam tube for adjustment of the erector lens.
