Abstract: An audio session management method may involve: determining, by an audio session manager, one or more first media engine capabilities of a first media engine of a first smart audio device, the first media engine being configured for managing one or more audio media streams received by the first smart audio device and for performing first smart audio device signal processing for the one or more audio media streams according to a first media engine sample clock; receiving, by the audio session manager and via a first application communication link, first application control signals from the first application; and controlling the first smart audio device according to the first media engine capabilities, by the audio session manager, via first audio session management control signals transmitted to the first smart audio device via a first smart audio device communication link and without reference to the first media engine sample clock.

Abstract: Technologies are generally described for delivery vehicles and containers for en route food product preparation. Modular food product preparation systems that may receive food items and supplies and prepare food product(s) en route such that the food product(s) is prepared by the time the system reaches a delivery destination may include trucks, railway cars, watercraft, and similar vehicles. Food preparation process steps and timing may be determined based on travel information (e.g., delivery destination, routes, etc.), as well as, food item and food product information. An on-board controller may determine the process steps and timing(s) and control operations of robotic devices arranged modularly in a container or vehicle to execute steps of the food preparation process. Alternatively or additionally, the on-board controller may receive instructions from a remote controller. Travel parameters of the vehicle may also be adjusted based on the food preparation process and/or travel information.

Abstract: A hybrid electric vehicle charging station (EVCS) is provided. The EVCS includes a charging chassis that is configured to support a charging circuitry for providing a charge current to an electric vehicle and a multi-conductor cable that is attached to the charging chassis and that receives the charging current from the charging circuitry and that transmits the charging current to the electric vehicle. The EVCS further includes a user interface that is attached to the charging chassis and that is configured to provide digital content to a vehicle operator during a charging event of the electric vehicle. The charging chassis includes multiple user interface attachment structures that are each configured to support the user interface.

Abstract: A DDoS attack mitigation system includes a plurality of stateless network devices connected to a network. The system also includes one or more DPI devices connected to the plurality of stateless devices. The system further includes a controller connected to the plurality of stateless devices and connected to the DPI devices. The controller includes logic integrated with and/or executable by a processor. The controller is configured to receive a signal from a first DPI device and analyze the received signal. The controller is further configured to update a network traffic policy to redirect at least some of network traffic destined for the first DPI device to one or more DPI devices different from the first DPI device based on the analyzed signal and to send a signal indicative of the updated network policy to at least some of the plurality of stateless devices.

Abstract: A system to transport and unload bulk materials includes at least one rail car and a moving wall system. The moving wall system has a first end, a second end, and a trough. The trough is configured to contain a payload of the at least one rail car. The trough includes sidewalls that contact the payload when loaded and move with the payload to move the payload towards the second end. The trough may be formed of at least one conveyor belt that forms a hopper of the at least one rail car. The trough may span a plurality of rail cars. The system may include a take-up system connecting the sidewalls. Each of the rail cars may include a frame and a plurality of pulleys connected to the frame may support the trough.
