| 20080201100 | METHOD AND APPARATUS FOR LOCATING THE TRAJECTORY OF AN OBJECT IN MOTION - An object locating system detects the presence of an object as it passes through a planar fields of view. A pair of optical sensor arrays with multiple, directed, pixel detectors observe the object from two angles as the object passes through the field of view. The location of penetration of the field of view is calculated by triangulation. Using this data, the known location of the take-off point and/or the delay between the departure of an object from the known take-off point and the penetration of the field of view, the trajectory of the object in time and space is calculated. In an alternate embodiment, the take-off point is not known and a plurality of pairs of optical sensor arrays may measure the trajectory of an object as it travels between a launch location and a target location. Applications include projecting the range of a driven golf ball, measuring the respective arriving and departing velocities of a hit baseball, determining the trajectory of a baseball, and determining the trajectory and origin of an arriving projectile, as in the case of the threat to a military vehicle. | 08-21-2008 |

| 20100217559 | Pace Calculation Watch - A watch that advantageously allows an athlete, such as a runner, to conveniently and instantly calculate a pace at which a distance was traveled. The watch includes a chronographic process and a pace calculation process. In order to determine a pace, the athlete enters the travel distance into the pace calculation process. The athlete then initiates a count by the chronographic process when he or she starts traveling the designated distance. When the athlete finishes traveling the designated distance, he or she stops the count, so that the chronographic process measures the total elapsed time required to travel the designated distance. The pace calculation process then obtains the total elapsed time from the chronographic process, and divides the designated travel distance by the total elapsed time to calculate the pace at which the distance was traveled. | 08-26-2010 |
