Abstract: Disclosed are techniques for determining an aiming adjustment amount, in terms of both vertical and horizontal aiming adjustments, to shoot a target at a target range by iteratively solving for the projectile trajectory (e.g., projectile drop or path and deflection) such that the iteratively calculated projectile trajectory is determined to pass through the target location within a predetermined threshold amount (e.g., at a projectile path calculation of about zero). Also disclosed are techniques for indicating whether a projectile has supersonic, transonic, or subsonic speed at a given range.

Abstract: A sighting device, such as a riflescope, a reflex sight, or a spotting scope, having a display device including an addressable, emissive collection of micro display elements for generating a finely pixelated, high-resolution aiming mark. The sighting device includes a controller coupled to the display device to selectively power one or more of the display elements to generate the aiming mark. The micro display elements may be inorganic light-emitting diodes (LEDs) having a pixel size of 25 ?m or less, and the display elements may be arranged at a pixel pitch of 30 ?m or less.

Abstract: A method for shooting a projectile weapon involves determining the inclination of a line of sight from a vantage point to a target and a line-of-sight range to the target, then predicting a trajectory parameter at the line-of-sight range, for a preselected projectile. Using the trajectory parameter, an equivalent horizontal range may then be determined, wherein the equivalent horizontal range is the range at which the trajectory parameter would be expected to occur if the projectile were shot from the vantage point toward a theoretical target located in a horizontal plane intersecting the vantage point. The equivalent horizontal range may be utilized to compensate for ballistic drop when shooting the projectile weapon. The method may be embodied in a handheld laser rangefinder including a memory for storing ballistic data. Systems for automatic hold over adjustment in a weapon aiming device are also disclosed.

Abstract: A reticle system for a variable optical power sighting device includes front and rear reticles proximate respective front and rear focal planes of the device. Range-compensating features are provided, such as a scale and a pair of bracketing marks formed in the rear reticle which cooperate with an indicator mark formed in the front reticle. The indicator mark is radially offset from the optical axis it appears to move in the field of view along the scale in response to adjustment of the optical power to thereby indicate a measurement corresponding to a size of a distant target subtended in the field of view by the bracketing marks. A two-part electronic reticle system is also disclosed utilizing similar principles of operation. The rear reticle and scale may be electroformed to reduce cost and improve light transmission relative to a glass reticle.

Abstract: A method for aiming a projectile weapon may utilize an aiming device having a primary aiming mark adapted to be sighted-in at a first selected range and one or more secondary aiming marks spaced below the primary aiming mark, and includes identifying, from at least two different groups of projectiles, a projectile group corresponding to a selected projectile. An aiming adjustment for the projectile weapon is determined and effected based on the range to the target and the nominal ballistic characteristics of the identified projectile group corresponding to the selected projectile. Other methods of aiming include identifying one projectile group from two or more predetermined projectile groups based on a selected projectile. Each predetermined projectile group preferably includes two or more different projectiles, preferably of different calibers, and a projectile having ballistic characteristics that are approximately median for each such projectile group.

Abstract: Measuring the size of a distant object using a gauge sized according to a range to the object is provided. A user may select an initial target scale size and use an aiming mark to align a rangefinder with the object before determining the range. Indicia may be associated with the gauge, both of which could be displayed in a field of view of an optical sighting device, such as a rangefinder, riflescope, or spotting scope. In addition, the gauge or the indicia, or both may be alterable in response to the determined range. While looking through an eyepiece of the optical sighting device, the user may align the gauge with the object and estimate its size by visually comparing the gauge and object with reference to the indicia. The gauge may be geometrically shaped and may contain a series of spaced apart measuring marks having a logarithmic spacing.
