Abstract: A computerized system and method of computerized bullet ballistic analysis is based on acquisition of depth profiles of the surface of a bullet under examination, estimation and compensation for coaxiality errors of the data acquired, and matching normalized data with reference data related to reference bullet(s) or a gun in question to determine whether the bullet under examination was fired from the gun in question. The computerized system includes a mechanism used for holding and rotating a bullet, a depth sensor measuring the depth profile of striations over part of the surface of the bullet, an analog to digital converter for receiving data from the sensor and sending digitized data to the computer where a computer program estimates and compensates the received digitized data for coaxiality errors and compares the normalized data of the bullet under examination with reference data.

Abstract: The present invention provides a computerized exercise system and method allowing exercising in both a gravity field and a gravity free environment. The exercise system includes one or more exercise modules positioned at specific locations and coupled to an exercise member through an extendable cable extending between each exercise module and one or more exercise members. A controlling structure controls tension forces in each of the cables for generating desired resistive forces in the exercise member at each point of its trajectory, simultaneously moving through a trajectory, defined by exercise parameters. When a user performs an exercise routine, he/she moves the exercise member and overcomes the resistive forces elevated by the exercise modules through the controlled tension forces in each cable.

Abstract: A multi-terrain amphibious vehicle adapted for travel across surfaces of various type and attributes is provided. The vehicle includes a chassis assembly (10) which extends in a longitudinal direction; a plurality of propulsion members rotatably coupled to that chassis assembly for propelling the vehicle across a given surface; and, a control mechanism for controlling the rotational velocities and phases of the propulsion members. The propulsion members each rotate about an axis that extends in a direction substantially normal to the longitudinal direction. Each propulsion member includes, for engaging the given surface, at least a first perimeter segment and a second perimeter segment coaxially disposed in angularly offset manner about its rotation axis. The first perimeter segment has an arcuate contour and extends radially farther from the rotation axis than does the second perimeter segment.

Abstract: An air lifted motion isolation system (100) includes a support structure or pod (110) for supporting equipment and/or personnel to be isolated from the motion of a waterborne craft (102). The support structure is coupled to the waterborne craft structure by a pivotal coupling assembly (120), permitting the support structure to be displaced both vertically and laterally. The motion of the support structure is stabilized by a lift producing body (130) disposed in the air above the waterborne craft and coupled to the support structure by a tether (112) for applying a substantially vertically directed force thereto. The pivotal coupling assembly (120) includes a plurality of pivotal coupling elements (122, 154) for buttressing the support structure above the structure of the waterborne craft. Each of the pivotal coupling elements (122, 154) may provide dampening to further stabilize and isolate the motion of the support structure from that of the waterborne craft.
