Abstract: A document used to assert a personal right has a randomized unique pattern of normally invisible but mechanically detectable material (e.g., finely divided ferromagnetic material) in a zone overlapping any visible indicia identifying the owner. The document is presented to a mechanical reader which scans the pattern along predetermined lines and records resultant output signals, along with an identifying record. Upon subsequent presentation, it is similarly scanned, for comparison with the recording to confirm its authenticity. Methods of producing appropriate patterns are disclosed.

Abstract: In a hydraulic forming tool of the diaphragm type, the punch and the work holder or die member are rigidly mounted on separate pistons that move in communicated cylinders, so that downward movement of one effects upward movement of the other by reason of displacement of fluid from the bottom of one of said cylinders to the bottom of the other. Adequate forming force is assured by metering outflow of fluid from the upper portion of the cylinder having the upgoing piston.

Abstract: A container with powder therein has its interior continuously communicated with a pressure gas source. An outlet from the container is controlled by a valve having a remotely controllable actuator that is isolated from its valve element, to prevent the actuator from being fouled by powder.

Abstract: The present disclosure relates to an antenna array including an integral antenna element structure mounted on a substrate. The integral antenna element structure includes a first set of antenna elements and a second set of antenna elements. Each antenna element including a first body and an adjacent second body. The second body is branched into a first leg and a second leg, wherein a transition pin forms an integral part with said first leg. The first set, and second sets of antenna elements are arranged such that the first body and the second body of each adjacent antenna element form a common tapered structure.

Abstract: A method for excitation of an array antenna across a specified bandwidth is disclosed. The specified bandwidth comprises M sample points, M being a positive integer >1, and the array antenna comprises N antenna elements, N being a positive integer ≥2. The method comprises forming a first matrix B(ω) defining an allowed frequency variation for an excitation coefficient for each antenna element, and forming a second matrix defining far field data for each antenna element at each sample point. Further the method comprises optimizing each excitation coefficient based on the formed first matrix and the formed second matrix, and controlling an excitation of the N antenna elements based on the optimized excitation coefficients. Hereby presenting a method for wideband optimization of the excitation coefficients for an array antenna.
