Abstract: A backend communications system can manage communications, using transmission control protocol (TCP), between a fleet of AVs in a given region and a backend system that manages transportation for the fleet of AVs. For each of the fleet of AVs, the backend communications system can select a designated one of a plurality of communication channels to transmit and receive transmission acknowledgments (ACKs). The backend communications system can transmit data packets to the fleet of AVs using any number of communication channels and receive ACKs from each of the fleet of AVs over the designated communication channel.

Abstract: An automated vehicle (AV) can be managed by a backend system and include an acceleration, braking, and steering system, an AV control system to maneuver the AV through road traffic throughout a given region, a memory to store a network resource map indicating locations of base stations and available network types providing coverage from the base stations throughout the given region, a communications array to transmit and receive communications from the backend system, and a communications system. The communications system can utilize the network resource map to dynamically select optimal network types from proximate base stations to communicate data with the backend system, and dynamically configure the communications array to connect with the optimal network types to transmit and receive data with the backend system.

Abstract: An autonomous vehicle (AV) tracking and updating system tracks locations of AVs traveling throughout a given region. Using a stored network resource map, the system identifies a number of network-limited areas in the given region, and determines when respective AVs will enter one of the network-limited areas. In response, the system transmits a set of configuration commands to a number of proximate AVs to establish a mesh network with the respective AVs.

Abstract: A system for managing network connections for AVs can store a spectrum heat map that indicates network coverage strength for networks throughout a given region. The system can identify a travel route for a selected AV. Using the spectrum heat map, the system can determine a connection schedule for the selected AV. The connection schedule can indicate location points along the travel route at which the selected AV is to switch from previous network connections to succeeding network connections. The system may then transmit the connection schedule to the selected AV to enable the selected AV to switch network connections at the location points along the travel route.

Abstract: An autonomous vehicle (AV) can include a communication system to communicate with a backend system, a sensor system to collect sensor data representing an operational environment of the AV, and a control system that can processes the sensor data to (i) perform a localization operation to determine a location and an orientation of the AV within a given region, and (ii) autonomously operate the AV's acceleration, braking, and steering system throughout the given region. Based on the localization operation, the AV can implement a set of configuration commands to configure the communication system to transmit and receive data with the backend system using a number of specified network nodes.

Abstract: Embodiments include articles, authentication methods and apparatus, and article manufacturing methods. An article includes a substrate with a first luminescent taggant, and an extrinsic feature with a second luminescent taggant, which is positioned proximate a portion of the article surface. The first and second taggants produce emissions in overlapping emission bands as a result of exposure to excitation energy. Above the extrinsic feature, the substrate and extrinsic feature emissions combine in the overlapping emission band to produce “confounded” emissions that are distinguishable from the substrate emissions taken alone. An authentication system determines whether, in a region corresponding to a “substrate-only” region of an authentic article, emissions having first emission characteristics are detected in the overlapping emission band.

Abstract: Elliptical exercise machines with a footskate on a reciprocating rail that provides for the ability to alter the horizontal stride of the user utilizing the machine, without significantly altering their vertical stride height on the machine. This is generally performed by altering the angle through which any point on the rail can, and does, move. Such adjustment may be performed by having the rail attached to a swing arm, where the arc of rotation of the swing arm relative to the frame is altered.

Abstract: Embodiments are directed towards network address based flood attack mitigation methods. A PTMD disposed between one or more computers may monitor several network flows and generate metrics associated with malicious network activity, such as, flood attacks. If flood attacks are determined to be occurring, the PTMD may determine the network addresses targeted by the flood attack. Further, the PTMD may activate flood attack mitigation procedures for the targeted network addresses such that other network addresses associated with the monitored network flows are excluded from the flood attack mitigation procedure. The PTMD may monitor the network traffic subsequently communicated to the targeted network addresses. Accordingly, the PTMD may determine if the flood attack has ceased based on characteristics of the monitored network traffic. If the flood attack has ceased, the flood attack mitigation procedures for the targeted network addresses may be deactivated.

For example, the determination of whether an autonomous vehicle is to be provided can be based at least in part on the destination specified with the transport request.

From the sensor information, a road condition is detected on a road segment, where the road condition has a sufficiently high likelihood of impairing autonomous vehicles in safely navigating through the one or more road segments. Information about the one or more road segments is communicated to the one or more autonomous vehicles.
