Patent ID: 8408460

Claim:
A method of indicating the expected location of a projectile relative to a target object with an optical sight, the method comprising the steps of: supporting an optical sight on a projectile launcher, the optical sight including a window; coupling an identification device of the window to a controller; identifying electronically an optical sight type parameter of the window device based on sensing and matching an electronic identifier from said window and matching said identifier with a profile stored in a library of profiles, wherein the library of profiles includes parameters of the optical sight, projectile launching device identification information, ranging system information, and ballistic identification information, said library of profiles further includes a plurality of projectile launcher operator identification information comprising a plurality of operator identifiers and operator calibration information associated with each of the operator identifiers, said operator calibration information is determined based on storage into said library of profiles of previous sight adjustments by a projectile launcher operator associated with the projectile launcher operator identification information; providing a user interface adapted to permit selection of one of the plurality of projectile launcher operator information; selecting one of the operator identifier information in said library of profiles using the user interface; determining a range to the target object; providing an alignment marker within the window of the optical sight; calibrating a position of the alignment marker based on said profile including the parameter of the window and said projectile operator information which is used to perform operator unique position calibration of the alignment marker; altering the position of the alignment marker within the window of the optical sight based at least on the range to the target object, a selected said profile stored in said library of profiles, said selected one of the operator identifier information, wherein the step of altering a position of the alignment marker includes the steps of: providing on a moveable base a first optical source which produces the alignment marker; and moving the movable base so that the alignment marker is in the altered position; providing a target acquired indicator viewable with the window of the optical sight, wherein the alignment marker is further adapted to alter to display a first and second state, wherein said alignment marker changing from said first state to said second state when the target has been acquired, said target acquired state further indicates the movable base has completed movement so that the alignment marker is in the altered position; wherein the optical sight includes a mount supporting the window, and the parameter of the window includes at least one of the maximum distance of the window from the optical source and the orientation of the window relative to the projectile launching device.
