Abstract: A hybrid swing drive system (1) of a hydraulic construction machine includes a variable displacement hydraulic swing pump (3) operable by a prime mover (2); a hydraulic swing motor (16) for performing a swing function of the machine; an accumulator (10); a controller (244); a swing control valve assembly (15) disposed in a first hydraulic path extending from the swing pump to the swing motor, the swing control valve assembly having a first position fluidly connecting the swing pump to a first side of the swing motor and a second position fluidly connecting the swing pump to a second side of the swing motor; and an accumulator control valve (12) having an open position fluidly connecting the accumulator to the first hydraulic path at an accumulator control valve connection point and a closed position fluidly isolating the accumulator from the first hydraulic path.

Abstract: A steering device for an aircraft landing gear leg including a main fitting has a steering collar for rotatably mounting on the outside of the main fitting; an actuator having an actuator body; and an actuator arm arranged to move between an extended position and retracted position with respect to the actuator body. The actuator arm is pivoted to the main fitting, and a bracket is pivoted to the main fitting; a second pivot location pivoted to the actuator body; and a third pivot location pivotally connected to one end of a steering arm. The steering arm is pivoted at its other end to the steering collar. Also, an aircraft landing gear with the steering device and aircraft having the landing gear.

Abstract: An interactive vehicle information map system is disclosed in which, in various embodiments, geographical, geospatial, vehicle, and other types of data, geodata, objects, features, and/or metadata are efficiently presented to a user on an interactive map interface. In an embodiment, the user may search vehicle-related data via the interactive map by providing search criteria including, for example, information regarding a geographic area, a time period, a vehicle, a vehicle owner, and/or a license plate number, among other items. The map system may provide search results including a list of vehicles that match the search criteria, vehicle information, and/or points on the interactive map that indicate license-plate recognition read locations, among other information. In an embodiment, the user may view detailed information associated with particular vehicles including, for example, captured images, vehicle-owner data, event history, and the like. Further, the user may export data and/or create search alerts.
