摘要:
Methods, devices, and systems are presented for calibrating or otherwise correcting the pointing accuracy of a gimbal. Measurements of the actual planes of rotation of each of a gimbal's rotatable elements is made using an off-board measurement device, such as a coordinate measuring machine (CMM). The measurements from the off-board device can be combined with those from native, on-board gimbal sensors of the rotation angles at which the planes are tilted/pitched with respect to their nominal planes of rotation. Information representing the error vectors between the nominal and actual planes of rotation is stored and used for correcting the pointing accuracy of the gimbal. The corrected pointing vector of the gimbal can be combined with measurements from an inertial measurement unit (INU) and rangefinder in order to accurately determine a geographic target position to which the gimbal points.

Multiple independently gimbaled devices, such as an electro-optical sensor and machine gun, are mounted to a rotating platform on a vehicle. The platform can rotate to prevent one device from blocking the other while aiming at an off-board location. A control system can harmonize the rotation of the device gimbals and rotating platform so that they remain pointed at the same location. The platform can be rotated to place a firing weapon downwind of a sensor or otherwise compensate for effects of one on the other.

Methods, devices, and systems are presented for compensating for gyroscopic drift in a stabilized gimbal system mounted on a vehicle. When the vehicle is parked and the gimbal is not being commanded to move by an operator, encoders or resolvers of the gimbal stabilized system are read and periodically read thereafter. When the vehicle begins to move or the gimbal is commanded to move, the last periodic reading of the resolvers is used to determine the amount that the gimbal has moved during the rest period. A gyroscopic drift rate is computed by dividing the amount of angular movement by the time period between the readings, and the gyroscopic drift rate is used for corrections while the vehicle is moving or gimbal is commanded to move. Each time the vehicle stops, the gyroscopic drift rate is re-computed and updated. The gyroscope can be heated until the drift rate is constant with respect to temperature, further helping the calibration.

High-bit depth sensors often capture more information then can be displayed on a commercially available display. Due to this, image processing systems and methods are disclosed to ensure that as much information as possible is presented to a user in a meaningful and statistically significant manner. The image processing systems and methods disclosed herein allow a user to view and process data that would otherwise be invisible to the user.
摘要:
A coupler that generates and emits a simulated missile signature for assessing the operational capability of a missile approach warning system. The coupler may be directly attached to the system by an adapter. Couplers may be used in multiplicity, simultaneously or sequentially. The simulated signature may be digitally stored, as may be the results of the assessment. Simulated signatures may also be generated from freeform. The coupler also performs sensitivity testing.

A system for reforming diesel fuel into hydrogen including feeds for water and diesel fuel, a supercritical water (SCW) reactor in fluid communication with the water feed and the diesel fuel, at least one pre-heater in thermal communication with the water feed, the diesel fuel feed that is configured to heat water from the water feed and diesel fuel from the diesel fuel feed to a predetermined temperature equal to or greater than the critical temperature of water before the water and the diesel fuel are mixed, a water-gas shift (WGS) reactor, and a hydrogen capturing system, where the SCW reactor reforms the diesel fuel into a synthesis gas comprising a mixture of hydrogen and carbon monoxide and outputs the synthesis gas, the synthesis gas output by the SCW reactor is fed into the WGS reactor which converts the carbon monoxide into carbon dioxide and hydrogen and outputs an output gas including a higher percentage of hydrogen to carbon monoxide compared to the synthesis gas, and the hydrogen in the output gas is captured by the hydrogen capturing system.
摘要:
A hand controller for controlling an electro-optic sensor of a weapons system may include a first cam/spring mechanism configured to provide non-linear displacement to an operator applying a torque to rotate the hand controller in a first direction. A second cam/spring mechanism may be configured to provide non-linear displacement to an operator applying a torque to rotate the hand controller in a second direction. A first sensor may be configured to sense torque being applied in the first direction and to generate a command signal to control rotation of the electro-optic sensor in the first direction. A second sensor may be configured to sense torque being applied in the second direction and to generate a command signal to control rotation of the electro-optic sensor in the second direction. The command signals may be substantially mathematically proportional rate command signals with respect to applied torque.
摘要:
A digital pressure controller that utilizes a microprocessor provides for control of the speed of a fluid pump engine for the purpose of maintaining specified pressures at both the inlet and outlet of the pump. Based upon pressure sensor output, and computations based on multiple calibrations between pump speed and pressure, and between output voltage and pump speed, a pump drive mechanism speed is determined by the control logic of the microprocessor, which speed maintains at least one of the inlet and outlet pressures within a specified range. The microprocessor may determine the specific weight of the fluid being pumped in order to select the pump drive mechanism speed.

A telescoping mast for supporting and raising a load may be telescopically extended by a zipper-action chain extension system further comprising a system for the management of one or more cables, such as power or communication cables traversing the length of the mast, and is capable of being locked into a rigid formation along a range of telescopic lengths.
