US12429684 - Riflescope adjustment systems

An adjustment assembly having a rotary encoder, riflescopes incorporating the same, and related methods are provided. In one example, an adjustment assembly includes a first rotational component configured to rotate about an axis, a first gear coupled with the first rotational component and a second gear coupled with the first rotational component. The assembly further includes an encoder. The encoder includes a position gear engaged with the first gear, the first gear and the position gear having a 1:1 gear ratio, and a revolution gear engaged with the second gear, the second gear and the revolution gear having a gear ratio other than 1:1, wherein the gear ratio of the second gear and the revolution gear independent of a ratio of the respective diameters of the second gear and the revolution gear. Sensors may determine the rotational positions of the position sensor and the revolution sensors.

Claim 1

A riflescope, comprising: a main tube; an objective system coupled to a first end of the main tube; an ocular system coupled to a second end of the main tube; an optical element disposed in the main tube; an adjustment assembly operable to alter a position of the optical element relative to the main tube, the adjustment assembly comprising: a rotational component configured to rotate about an axis; a gear comprising gear teeth engageable with the rotational component; a magnetized component integrally coupled to the gear at a gear location within a perimeter of the gear defined by the gear teeth; and a sensor to sense a rotational position of the magnetized component, the rotational position of the magnetized component correlating to an angular displacement of the rotational component about the axis relative to a zero point. a main tube; an objective system coupled to a first end of the main tube; an ocular system coupled to a second end of the main tube; an optical element disposed in the main tube; an adjustment assembly operable to alter a position of the optical element relative to the main tube, the adjustment assembly comprising: a rotational component configured to rotate about an axis; a gear comprising gear teeth engageable with the rotational component; a magnetized component integrally coupled to the gear at a gear location within a perimeter of the gear defined by the gear teeth; and a sensor to sense a rotational position of the magnetized component, the rotational position of the magnetized component correlating to an angular displacement of the rotational component about the axis relative to a zero point. a rotational component configured to rotate about an axis; a gear comprising gear teeth engageable with the rotational component; a magnetized component integrally coupled to the gear at a gear location within a perimeter of the gear defined by the gear teeth; and a sensor to sense a rotational position of the magnetized component, the rotational position of the magnetized component correlating to an angular displacement of the rotational component about the axis relative to a zero point.
