Method and apparatus to provide precision aiming assistance to a shooter
First Claim
1. An aiming system to provide aiming assistance to a shooter comprising:
- a wind-reading scope to determine a wind speed;
a windage compensation table to provide a windage variable, wherein the windage table is based on ballistic coefficients compensated for at least one of an ambient temperature and an ambient pressure; and
a processing module comprising;
an interface circuit to receive the windage variable; and
a processor circuit programmed to compute a hold-off value for the wind-reading scope based on at least the wind speed and the windage variable.

Abstract
An aiming system provides precision aiming assistance to a user based on the availability of a windage variable that is used in the computation of a windage hold-off. In an exemplary embodiment, the aiming system comprises a processing module, a wind-reading scope, and a windage compensation table comprising tabulated windage variables. In one or more other embodiments, the aiming system further comprises a security module, which may be used to store the windage compensation table in electronic form, store an authorization code, or otherwise serve as an enabling device for operation of the aiming system. Regardless, unless a valid windage variable as obtained from the windage compensation table is made available to the processing module, the aiming system does not compute a precision hold-off. If the windage variable is available, along with any other needed parameter, such as target range and wind speed, the processing module computes the hold-off value.
