Abstract: A method for manufacturing substantially moisture resistant closures for flexible packages, the method comprising providing a roll of material, printing a design on the roll, heating the roll, forming a three-dimensional shape in the roll substantially proximate to the design and cutting the roll substantially proximate to the three-dimensional shape and the design.

Abstract: A system that includes a synchronized network of three search and track radars and associated processing means and communication channels. The radars are configured to detect and track the target. In response to detected target, an interceptor is launched towards the target. The radars are configured to measure and track the target and the interceptor. The target and interceptor ranges are accurately measured by the radars in the synchronized network, giving rise to synchronized accurate range measurements that are combined by range triangulation to provide accurate target and interceptor position measurements irrespective of the angular measurement accuracy of each radar. The processing means are configured to utilize the measurements to calculate interceptor maneuvers required to overcome errors and bring the interceptor close to a target. The maneuver commands are transmitted to the interceptor using the communication channel.

Abstract: A control system for controlling an airborne vehicle at a time of low aerodynamic moment is provided. The control system includes combined aerodynamic and thrust vector control actuators, a quaternion generator which determines a quaternion error value defining the error between the quaternion of the vehicle and the commanded quaternion; and a controller which controls the actuators based on the quaternion error value, an aerodynamic control gain and a thrust vector control gain.
