Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path. The metadata TLV field may identify a service action to be performed by a downstream SFC entity. For example, the metadata TLV field may instruct the downstream SFC entity to drop the packet, to redirect the packet (or a traffic flow associated with the packet), to mirror a traffic flow, to terminate a communication connection, to start or stop a packet accounting, and/or to apply a higher grade of service. Alternatively, the metadata TLV field specifies an OAM service action list that identifies service actions that have been performed on the packet.

Abstract: The disclosure relates to a fuel injection valve that includes a valve needle, a closing spring applying a spring force to the valve needle, which spring force loads the valve needle in the direction of a closing position, and an actuator assembly. A coil of the actuator assembly produces a magnetic force on a magnet armature of the actuator assembly such that, as the magnet armature travels toward a pole piece of the actuator assembly, the magnet armature covers an idle stroke to a stop element of the valve needle and then carries the valve needle toward the pole piece. A spring constant of the closing spring and the magnetic force are matched such that the magnitude of the resultant force of the spring force and the magnetic force decreases with increasing distance of the valve needle from the closing position and remains the same with increasing the distance.

Abstract: Operation of an autonomous vehicle is modified based on the driving style preferences of a passenger. A machine learning module for a motion planner of the autonomous vehicle accepts input relating to driving style of the autonomous vehicle including data representing autonomous vehicle speed, acceleration, braking, or steering during operation. The passenger also provides feedback relating to the vehicle's driving style during operation, and the passenger feedback is used to train the machine learning module to create a personal driving style decision-making model for the passenger that controls operation of the autonomous vehicle. A personal driving style preference profile for the passenger also may be obtained by collecting motion sensor data relating to driving habits of the passenger when the passenger is a driver. The driving style preference profile is used by the motion planner to modify operation of the autonomous vehicle in accordance with the driving style preference profile.

Abstract: The present disclosure provides a method and device for in-vehicle payment. A face image of an in-vehicle user and a geographic location of the in-vehicle user are received at a point of a ride route traveled by a vehicle occupied by the in-vehicle user.

The image set includes face images of a plurality of users. The face image of the in-vehicle user is compared with face images in the image set to determine an identity of the in-vehicle user. A fare deduction account corresponding to the in-vehicle user is identified using the identity of the in-vehicle user. A fare corresponding to the ride route is deducted from the fare deduction account.

Abstract: Processes and compositions are described for preparing new, colloidally stable, coated nanomagnetic particles useful for both in-vitro and in-vivo biomedical applications, including cell targeting and capturing cells, microorganisms, and cellular organelles or entities such as exosomes. These nanomagnetic particles can also be used as imaging contrast agents due to their small size and high magnetic moment. The nanomagnetic particles include a series of sequentially added, stabilizing surface coatings rendered onto nano-sized magnetic crystal clusters (e.g., magnetite particles) to impart colloidal stability in complex biological samples with minimal leaching of the coating materials, high binding capacity, and low non-specific binding. Another benefit of this invention is the ability to utilize both external and internal magnetic field-generating separation devices to effect separation of the magnetic nanoparticles.
