Abstract: A missile system wherein a missile carrier delivers a plurality of submissiles over a target area. A passive or active scanner on the missile carrier repeatedly scans the target area as the missile carrier descends by drag brake over the target area. Submissile assignment to identified targets is performed at a selected altitude. A data processor controls the launching of the submissiles and actively guides the submissiles for substantial portions of their flights via optical fiber or wire links separately connecting each submissile to the missile carrier. Each submissile includes either passive or active identification devices enabling the data processor to track the submissiles individually. A missile assignment table stores a correspondence between identified targets and submissiles assigned thereto. Submissile assignment is effected on the basis of the strength of target signature.

Abstract: A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bays. An air seal is formed at the periphery of each opening by resiliently flexible side seals and a top seal to form a highly airtight interface between the pallet assembly and the adjacent airflow opening. When a pressure differential is developed between the chamber and the pallet bay, air is efficiently drawn substantially exclusively through the pallet assemblies with minimal leakage. The flexible sealing arrangement accommodates pallet assemblies with unevenly stacked rows of cases without significant loss of system efficiency.

Abstract: An operator ride enhancement system that is coupleable to the frame of a vehicle includes a counterweight platform moveably coupled to the frame, and a resilient member engaged with the frame and the counterweight platform. The mass of the counterweight platform is configured to be approximately at least equal to a total mass supported by the counterweight platform during operation of the vehicle. The operator ride enhancement system attenuates and/or inhibits movement of the counterweight platform during operation of the vehicle.

Abstract: An EGR apparatus includes an EGR passage to allow part of exhaust gas discharged from an engine to an exhaust passage to flow as EGR gas into an intake passage; an EGR valve to regulate an EGR flow rate in the EGR passage; various sensors for detecting an engine running state; and an ECU to control the EGR valve based on the detected running state to diagnose abnormality in the EGR valve. The ECU calculates a reference intake pressure according the detected engine rotation speed and load by reference to a reference intake pressure map showing a relationship of the reference intake pressure to engine rotation speed, and engine load, and determine whether or not the EGR valve has abnormality in opening/closing by comparing the reference intake pressure with the detected intake pressure.

Abstract: Various embodiments are directed to a docking station for the mechanical alignment of an autonomous robotic platform. A correlator may receive the wheels of a moving autonomous robotic platform. A first set of rollers in the correlator may align the wheels, in a substantially linear direction, into a space created by a second set of rollers attached to a frame of a backstop. The second set of rollers may continue to align the wheels of the moving autonomous robotic platform until the wheels come in contact with a stopping roller coupled to the backstop. The stopping roller may be vertically oriented at a height above a wheel radius of the autonomous robotic platform. The stopping roller provides a force to prevent further forward travel. Upon being stopped by the stopping roller, the autonomous robotic platform is positioned for mating with charging contacts in the docking station.
