Patent number: 7335116Abstract: An object locating system detects the presence of an object as it passes through two consecutive planar fields of view. Two pairs of optical sensor arrays with multiple, directed, pixel detectors observe the object from two angles as the object passes through each consecutive field of view. The locations of penetrations of the respective fields of view are calculated by triangulation. Using this data, the known location of the take-off point and/or the delay between penetrations, the trajectory of the object in time and space is calculated. Applications include projecting the range of a driven golf ball, measuring the respective arriving and departing velocities of a hit baseball, and determining the trajectory and origin of an arriving projectile, as in the case of the threat to a military vehicle.Type: GrantFiled: October 15, 2004Date of Patent: February 26, 2008Inventor: Dimitri Petrov

Patent number: 7156789Abstract: A mobile apparatus for assisting a person with limited mobility. The apparatus is also for developing a higher level of mobility in a person having low mobility. The person may be assisted by the apparatus when walking. The apparatus includes a seating surface resiliently mounted to provide partial body weight support to the person. A person using the mobility assist may grasp lateral handles disposed on the apparatus while walking or he/she may attempt to mobilize without the use of the lateral handles. Multiple elastic cords positioned to generate a lifting force that varies according to the number of elastic cords employed provide the degree of resilience in the seat. The degree of resilience may be adjusted in accordance with the relative collapse of the lower extremities of the person. As the walking ability of the person progresses, such lifting force may be reduced overtime by reducing the number of elastic cords employed.Type: GrantFiled: June 3, 2004Date of Patent: January 2, 2007Inventor: Avinoam Nativ
