Abstract

An weapon sight system includes a weapon sight having body with an optical element that is configured to superimpose a reticle that is visible through the optical element. The weapon sight includes a controller in electronic communication with and configured to control a light source. The light source may include an LED for generating a reticle image on the optical element at a plurality of different brightness conditions. The light source may include an array of LEDs for generating multiple different reticle images on the optical element. The weapon sight includes a Hall effect sensor in electronic communication with the controller to adjust user-selectable settings including reticle brightness or reticle image. The weapon sight system includes a magnetic input device for providing an input to the Hall effect sensor of the weapon sight.

Claims (42)

1 . A weapon sight comprising:

a body;

a controller enclosed within the body;

a power source in electronic communication with the controller and enclosed within the body;

a light source in electronic communication with and controlled by the controller, the light source disposed within the body and operable to generate a reticle image;

a frame extending from the body;

an optical element, the optical element supported within the frame and arranged to visually display the reticle image and being one of reflective or holographic; and

a Hall effect sensor in electronic communication with the controller, the Hall effect sensor arranged to generate an input signal in response to a magnet of an input tool coming into proximity to the Hall effect sensor;

wherein the controller is operable to adjust a user-selectable setting associated with the reticle image in response to receiving the input signal generated by the Hall effect sensor, wherein the user-selectable setting is one of: a brightness profile setting, a reticle design setting, an azimuth adjustment setting, an elevation adjustment setting, or combinations thereof; and

wherein the input tool is separate from the weapon sight.

2 . The weapon sight of claim 1 , further comprising an ambient light sensor in electronic communication with the controller and arranged to generate a brightness signal representative of an ambient light condition, wherein the controller is arranged to control a brightness of the light source based on the brightness signal generated by the ambient light sensor.

3 . The weapon sight of claim 2 , wherein the user-selectable setting is the brightness profile setting, wherein the controller comprises a memory device storing a plurality of user-selectable brightness profiles; the controller being operable to adjust among the plurality of user-selectable brightness profiles based on the input signal; and wherein the reticle image is based on a combination of a one of the user-selectable brightness profiles and the brightness signal.

4 . The weapon sight of claim 3 , wherein the plurality of user-selectable brightness profiles comprises a first brightness profile for use under natural sunlight, a second brightness profile for use indoors, and a third brightness profile for use in low-light conditions.

5 . The weapon sight of claim 1 , wherein the user-selectable setting comprises the reticle design setting.

6 . The weapon sight of claim 5 , wherein the controller comprises a memory device storing a plurality of user-selectable reticle designs, the plurality of user-selectable reticle designs comprises a dot, a starburst, a crosshair with center dot, and a circle with center dot.

7 . The weapon sight of claim 1 , wherein the Hall effect sensor is disposed adjacent an internal surface of a side wall of the body.

8 . The weapon sight of claim 1 , wherein the Hall effect sensor is disposed on a side of the frame.

9 . A weapon sight system comprising:

a weapon sight comprising

a body;

a controller enclosed within the body;

a light source enclosed within the body and in electronic communication with the controller, the controller being arranged to control the light source to generate a reticle image; and

a Hall effect sensor disposed within the weapon sight and in electronic communication with the controller;

wherein the weapon sight comprises a recess formed proximate the Hall effect sensor; and

a magnetic input tool, the magnetic input tool including a tip shaped to correspond to the recess, the tip including a magnet;

wherein the Hall effect sensor is arranged to generate an input signal when the tip of the magnetic input tool is received in the recess; and

wherein the controller is operable to adjust a user-selectable setting associated with the reticle image in response to receiving the input signal generated by the Hall effect sensor.

10 . The weapon sight system of claim 9 , further comprising an ambient light sensor in electronic communication with the controller and arranged to generate a brightness signal representative of an ambient light condition, wherein the controller is arranged to control a brightness of the light source based on the brightness signal generated by the ambient light sensor.

11 . The weapon sight system of claim 10 , wherein the controller comprises a memory device storing a plurality of user-selectable brightness profiles; the controller being operable to adjust among the plurality of user-selectable brightness profiles based on the input signal; and wherein the reticle image is based on a combination of a one of the user-selectable brightness profiles and the brightness signal.

12 . The weapon sight system of claim 9 , wherein the user-selectable setting comprises a reticle design.

13 . The weapon sight system of claim 12 , wherein the controller comprises a memory device storing a plurality of user-selectable reticle designs, the plurality of user-selectable reticle designs comprises a dot, a starburst, a crosshair with center dot, and a circle with center dot.

14 . The weapon sight system of claim 9 , wherein the magnetic input tool comprises a stylus, wherein the tip is a first tip, the magnet is a first magnet at a first orientation, and the input signal is a first input signal, wherein the stylus further comprises a second tip, the second tip comprising a second magnet at a second orientation different from the first orientation.

15 . The weapon sight system of claim 14 , wherein the weapon sight comprises a second Hall sensor, the weapon sight further comprising a second recess proximate the second Hall effect sensor, the second tip shaped to correspond to the second recess, wherein the second Hall effect sensor is arranged to generate a second input signal when the second tip of the magnetic input tool is received in the second recess; and wherein the controller is operable to adjust the user-selectable setting associated with the reticle image in response to receiving the second input signal generated by the second Hall effect sensor, different from the first input signal.

16 . A method for controlling a weapon sight having a Hall effect sensor, the method comprising:

generating, by a controller in electronic communication with a light source, a first reticle image at an optical element, the first reticle image having a first reticle design, a first brightness profile, a first azimuth setting and a second elevation setting;

receiving, by the controller, an input signal generated by the Hall effect sensor, the input signal representing a user input presenting a magnet in proximity to the Hall effect sensor, the magnet being of an input tool that is separate from the weapon sight;

adjusting, by the controller, a user-selectable setting in response receiving the input signal generated by the Hall effect sensor, wherein the user-selectable setting is one of: a brightness profile setting, a reticle design setting, an azimuth adjustment setting, an elevation adjustment setting, or combinations thereof; and

generating, by the controller, a second reticle image, different from the first reticle image by the adjusted user-selectable setting.

17 . The method of claim 16 , further comprising receiving, by the controller, a mode signal to toggle an adjustment mode for adjusting the user-selectable setting.

18 . The method of claim 17 , wherein the input signal is based on a first swipe type and the mode signal is based on a second swipe type.
