Abstract: A process for modifying the surface of a polymeric substrate is disclosed, wherein said process is comprised of contacting a surface of a polymeric substrate with a protic liquid or fluid containing a diazonium composition under such conditions that will effectively allow the reaction of the diazonium composition with the surface, resulting in the attachment of aromatic groups to the polymeric surface. The polymeric substrate contains aliphatic carbon-hydrogen bonds, while the protic composition is comprised of a diazonium complex formed by diazotizing an amino compound comprised of at least one amino group bonded to an aromatic group. Also disclosed are the products generated using the aforementioned surface modifications.

Abstract: The in-situ robotic testing system uses a robotic probe positioning apparatus, attached to the system under test, to position the probe head and its associated probe tip at a selected location on the printed circuit board under test. Access to the printed circuit board under test is facilitated by the removal of the printed circuit board in the adjacent slot in the card cage. The robotic probe positioning apparatus comprise motors and associated control software. The control software can process user input and direct the motors to place the probe tip. The control software also directs the probe to perform the testing and provides the test results to the user. X-axis, Y-axis and Z-axis motors are used to control the linear movement of the probe head and two rotational motors control the position and orientation of the probe tip relative to the circuitry and engage the probe tip with the particular circuit trace on the printed circuit board.

Abstract: A military range scoring system with a plurality of imagers capable of viewing reference points and impact points for ordinance aimed at the reference points, imager position controllers, and data processors and video monitors for processing and viewing data received from said imagers; and communication links between the components. The imagers are preferably infrared or near-infrared, and the system manually and/or automatically scores impacts by digital signal processing of imager data.

Abstract: The invention is a system and method for calibrating a robotics system. The invention measures the actual performance of the robotics system when positioning objects at several calibration positions within an operational area. The invention then determines corrective factors based on the performance measurements. The robotics system uses the corrective factors to overcome positioning errors and operate in the field with extreme precision. The calibration system comprises a control system, a laser projection device, a plate, and a laser detection device. The robotics system positions the laser projection device to project a laser beam through a hole in the plate and onto a laser detection area on the laser detection device. The control system then directs the robotics system to move the laser projection device to a plurality of calibration positions.

Abstract: The printed circuit board fault injector circuit uses an automated fixture to enable a robot arm mechanism to position a probe at a designated test node on the printed circuit board under test and apply a fault signal thereto. The test apparatus ensures that the designated node is in contact with the fault injector probe and controllably applies a voltage and/or current signal of selected magnitude to the test node to typically create a stuck-at-one or a stuck-at-zero fault or any other definable condition. The fault injector probe produces a stuck-at-zero fault that is not subject to spurious high frequency harmonics by extending the dynamic range of the fault injector circuit to apply a negative voltage to the test node to rob the output stage of the logic circuit that drives the test node of all drive current, thereby forcing a solid stuck-at-zero condition.

Abstract: A piston-cylinder combination having a piston arranged for reciprocating movement within a cylinder under fluid pressure, the fluid pressure being ultimately delivered to the sides of the piston with a connector rod from the piston controlling the movement of valves for the delivery of fluid to the piston. The fluid valves are alternatively exposed to fluid under pressure to insure proper opening and closure thereof. The valving combination from the alternate sides of the piston eliminates chattering or floating of the piston, particularly when the piston is under a "no load" condition.

Abstract: A fluid pressure servo detent mechanism for controlling movement of a piston within a cylinder including one-way inlet and outlet valves for controlling the fluid pressure within the cylinder with linkage means interconnecting the inlet and outlet valves and the moveable piston for simultaneously actuation thereof. A control or sensing rod is carried by the piston for movement therewith to provide a control element for articles to be controlled or to sense the position of the piston and the flow of fluid or receipt of pressure to the outlet may be utilized to determine the position of the piston and as a signal to additional equipment.
