Abstract: In a first participant in a network—such as an ad hoc wireless network—a facility performs peer regulation of the network. The facility monitors behavior of a second participant in the network that has appointed itself a routing participant for the network. Among the monitored behavior, the facility identifies behavior of the second participant that is inconsistent with its routing participant status. In response to this identifying, the facility sends a message to participants of the network including a third participant indicating that the second participant is no longer a routing participant.

Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

Abstract: A facility for operating a communication device is described. The facility joins a network to which one or more other communication devices are connected, and identifies a type of network service not being provided in the network. In response, the facility determines to provide the identified type of network service in the network, and proceeds to provide the identified type of network service in the network.

Abstract: A facility for operating a first node in a mesh network having other nodes is described. The first node directly receives signals each encoding an identifier of one of the other nodes, at least a portion of the signals also encoding an indication that the node having the identifier has appointed itself a routing node. The facility determines a first value equal to the number of unique node identifiers encoded in signals received during a first period of time, and a second value equal to the number of unique node identifiers encoded by signals received during the first period of time that also encode the indication. The facility determines a routing score for the first node based at least upon the first value and the second value that reflects the first node's suitability as a routing node in the mesh network.

Abstract: An Augmented Reality (AR) wayfinder tracks the current location of a user within an indoor location relative to a path defined through the indoor location for the user. The path is broken into segments, each segment is a straight line between two nodes, and each node represents either a starting point in the path, a turn along the path, or an ending point in the path. As the user traverses the path, a remaining distance between the user device and the next node in the path is calculated. An AR object with attributes that correlate to the remaining distance to the next node is blended into and superimposed into a video that the user is viewing through the user device of the physical environment as the user travels along the path.

Abstract: Seamless connectivity utilizing multi-domain security by storing a global key on each participant computing devices. When a participant computing device tries to connect to a network, the network sends encryption keys for that network in response to that participant computing device providing the global key and not being blacklisted. The participant computing device can then connect to the network using that network's encryption key. A meta-message container is generated for the message based on a next participant in a route from the transmitting participant to the destination participant. One or more series of one or more line items are generated for the message, with each line item being tagged tag with network information. The line items are encrypted based on the network information. The meta-message container and the encrypted series of line items are then transmitted to the next participant.

Abstract: A facility that controls participants in an ad hoc peer wireless network to use transmission power level settings and routing paths that best serve individual participants in the network and the network as a whole is described. Variously, the facility modulates transmission power levels to extend participant battery life and reduce the likelihood of radio interference in the network; establishes routing paths that contribute to the effectiveness and continuing operation of the network; and monitors for and responds to the occurrence of interference in the network's communications.

Abstract: Embodiments described herein are directed to tracking objects using a cognitive heterogeneous ad hoc mesh network. A first participant receives a notification signal from a second participant. The first participant determines first positioning information from the notification signal and second positioning information from characteristics of the received signal. If the difference between the first and second positioning information is below a first threshold, then the second participant is within line-of-sight of the first participant. If the difference is above the first threshold and below a second threshold, then the second participant may have a malfunctioning sensor. But if the difference is above the second threshold, then the second participant is not within line-of-sight of the first participant and the received signal was reflected off another object. The positioning information can then be refined or transmitted to other participants.

Abstract: Techniques for providing a contextual voice user interface that enables a user to query a speech processing system with respect to the decisions made to answer the user's command are described. The speech processing system may store speech processing pipeline data used to process a command. At some point after the system outputs content deemed responsive to the command, a user may speak an utterance corresponding to an inquiry with respect to the processing performed to respond to the command. For example, the user may state “why did you tell me that?” In response thereto, the speech processing system may determine the stored speech processing pipeline data used to respond to the command, and may generate output audio data that describes the data and computing decisions involved in determining the content deemed responsive to the command.

Abstract: Improved techniques for recovering from an error condition without requiring a re-transmittal of data across a high-speed data link and for improved power usage are disclosed herein. A data stream is initiated. This stream includes different types of packets. Error correcting code (ECC) is selectively imposed on a control data type packet. A transmitter node and a receiver node are connected via a hard link that has multiple virtual channels. Each virtual channel is associated with a corresponding power-consuming node. When the receiver node receives the control data type packet, error correction is performed if needed without re-transmittal. When a final data type packet is transmitted for each virtual channel, the transmitter node transmits an end condition type packet. A corresponding power-consuming node that corresponds to the respective virtual channel transitions from an active state to a low power state.
