20090200376 | BALLISTIC RANGING METHODS AND SYSTEMS FOR INCLINED SHOOTING - 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. | 08-13-2009 |
20100282845 | RANGEFINDERS AND AIMING METHODS USING PROJECTILE GROUPING - A method for aiming a projectile weapon involves identifying a projectile group corresponding to a selected projectile and its nominal initial velocity from at least two different predetermined groups of projectiles, determining a range to a target, and automatically determining an aiming adjustment for aiming the projectile weapon based on the range to the target and a nominal ballistic characteristic of the projectile group. The nominal ballistic characteristic of the projectile group may be characteristic of a ballistic coefficient of the selected projectile and the nominal initial velocity of the selected projectile. Also disclosed are systems and methods for determining hold over aiming data and equivalent horizontal range data, for aiming projectile weapons at inclined targets. | 11-11-2010 |
20110021293 | CONFIGURABLE RANGEFINDING DEVICES AND METHODS - Systems and methods are provided to selectively measure one or more conditions, such as temperature, wind speed, and angle of inclination, that may assist a golfer in making a play. If it is not permissible to present to the golfer additional information (e.g., an adjusted distance, temperature, wind speed, or a suggested club) that may assist a golfer in making a play, only a line-of-sight distance to a target on a golf course may be displayed. Modular rangefinders are also provided in which a dongle is coupled to a rangefinder to provide unique functionality. For example, a TGR™ dongle may provide golf specific functionality, such as calculating an adjusted distance that the golfer may use to play an inclined shot and a TBR® dongle may provide hunting specific functionality, such as calculating an equivalent horizontal distance that a hunter may use for precise shooting on an incline. | 01-27-2011 |
20110296733 | MULTI-COLOR RETICLE FOR BALLISTIC AIMING - According an embodiment, a projectile weapon aiming system includes a computer-controllable reticle with crosshairs or other aiming marks having a color and/or illumination that can be selectively changed to provide feedback to a shooter to indicate when the projectile weapon aiming system (and hence the projectile weapon itself) is accurately aimed to compensate for a particular range, inclination, crosswind, and/or other ballistic conditions. | 12-08-2011 |
20120246992 | RANGEFINDERS AND AIMING METHODS USING PROJECTILE GROUPING - 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.

Systems for automatic hold over adjustment in a weapon aiming device are also disclosed. | 10-04-2012 |
20130170027 | OPTICAL RANGEFINDER AND RETICLE SYSTEM FOR VARIABLE OPTICAL POWER SIGHTING DEVICES - 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. | 07-04-2013 |
20140274499 | VIBRATING PROJECTILE - A projectile that includes a vibrating function is presented. The vibrating projectile, such as an arrow, is structured to penetrate flesh of an animal more easily than a standard projectile. After the arrow has reached its target, a switch turns on a vibrating mechanism that causes the arrowhead, such as a broadhead to vibrate as it is traveling into the animal. This deeper penetration causes more injury to the animal and reduces the time between arrow penetration and animal expiration. | 09-18-2014 |
20140274500 | PROJECTILE PRODUCING ELECTRICAL SHOCK - A projectile that includes a shocking function is presented. The projectile, such as an arrow, is structured to shock an animal as the arrow strikes its target. A capacitor may be used to store energy to generate the shock, or a shocking circuit may be self-contained. The shocking mechanism may be controlled by switch. In other embodiments electrically isolated electrodes could be present on the arrow, including the broadhead, that automatically cause the shocking system to discharge when the arrow has reached its target. The shocking function may be combined with a vibrating function for an even more lethal strike. | 09-18-2014 |
20150013206 | RANGING METHODS FOR INCLINED SHOOTING OF PROJECTILE WEAPONS - 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.
