Abstract: A hydraulic valve for a cam phaser, the hydraulic valve including a bushing element, including a longitudinal channel, a pressure medium connection that is arranged at an end of the longitudinal channel, three hydraulic connections that originate from the longitudinal channel, and a pressure balanced hollow piston that is arranged axially moveable within the longitudinal channel, characterized in that the hydraulic valve includes a check valve at the pressure medium connection and a cam phaser including a stator and a rotor that is rotatable relative to the stator between a first end position and a second end position for adjusting a cam shaft of an internal combustion engine and a hydraulic valve for controlling a rotation of the rotor.

Abstract: Systems, methods, and apparatus for identifying and tracking UAVs including a plurality of sensors operatively connected over a network to a configuration of software and/or hardware. Generally, the plurality of sensors monitors a particular environment and transmits the sensor data to the configuration of software and/or hardware. The data from each individual sensor can be directed towards a process configured to best determine if a UAV is present or approaching the monitored environment. The system generally allows for a detected UAV to be tracked, which may allow for the system or a user of the system to predict how the UAV will continue to behave over time. The sensor information as well as the results generated from the systems and methods may be stored in one or more databases in order to improve the continued identifying and tracking of UAVs.
