Abstract: Disclosed herein are systems and methods for detection of a path break in a communication network by one network appliance of a plurality of network appliance. A communication path that is transitioning from active to idle state can be quickly determined by evaluating network data traffic within a predetermined time interval after the end of a data transmission. By strategically utilizing health probes at only a set predetermined time interval after a data transmission, a path break condition can be quickly determined without significant use of network bandwidth. Further, the path break condition can be determined unilaterally by one network appliance.

Abstract: An internal combustion engine includes a cam-actuated rocker arm assembly with a solenoid-actuated latch that provides for cylinder deactivation or variable valve actuation. The solenoid is in a position where its inductance varies significantly in relation to the position of a latch pin as it translates between latching and non-latching configurations. A sensor is positioned to monitor a current or a voltage in a circuit that includes the solenoid. The sensor data is analyzed to provide diagnostic information relating to the operation of the rocker arm assembly.

Abstract: Disclosed herein are systems and methods for the collection, aggregation, and processing of network traffic statistics for a plurality of network appliances in a wide area network. Select network traffic statistics can be collected and associated with a hierarchical string, and aggregated over time. In this way, only information that is likely to be relevant is gathered and maintained, allowing for the maintenance of select network traffic statistics for large-scale operations.

Abstract: A hydraulically-actuated device comprises a self-contained fluid reservoir comprising a tank for receiving a fluid, a reservoir port, and a flexible diaphragm. An actuation member comprises a hydraulically actuated piston in a cylinder. A pump case comprises an inlet port and an outlet port, the inlet port in fluid communication with the reservoir port, and the outlet port in fluid communication with the actuation member. A pump is within the pump case. The pump can be a reversible pump. The flexible diaphragm can flex in to the fluid reservoir when the pump transfers a fluid from the fluid reservoir to the actuation member and can flex away from the fluid reservoir when the pump transfers fluid from the actuation member to the fluid reservoir. The flexible diaphragm can hermetically seal a fluid within the fluid reservoir and have a second side in communication with atmospheric pressure.

Abstract: Disclosed herein are systems and methods for multi-level classification of data traffic flows based in part on information in a first data packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated to track data traffic flows by application names and data packet information or properties. Based in part on these keys, patterns can be discerned to infer data traffic information based on only the information in a first data packet. The determined patterns can be used to predict classifications of future traffic flows with similar key information. In this way, data traffic flows can be classified and steered in a network based on limited information available in a first data packet.

Abstract: A method of operating an internal combustion engine that includes a valvetrain having a rocker arm assembly including a rocker arm on which a latch pin is mounted. An actuator for the latch pin, including an electromagnet, is mounted separately from the rocker arm. Rocker arm position information is obtained by gathering and analyzing data relating to a current or voltage in an electrical circuit that is operative to power the electromagnet. The rocker arm position information is used to perform a diagnostic.

Abstract: Disclosed herein are systems and methods for forward packet recovery in a communication network with constrained network bandwidth overhead. In exemplary embodiments, a target byte protection ratio is determined. Error correcting frames are dynamically generated by a first processor such that error correcting information can be generated to approximate the target byte protection ratio. The data packets and error correcting information are then transmitted across one or more communication networks to a second processor. The second processor can use the error correcting information to regenerate or replace data packets missing or corrupted in transmission across one or more communication networks.
