Abstract: A wireless mesh network system includes network nodes that operate in blink and canopy modes of operation. In operation, a network manager joins nodes operating in the canopy node to the network and allocates network bandwidth to the canopy nodes. The allocated bandwidth includes a first bandwidth allocated for transmitting and receiving data packets between canopy nodes that are joined to the network, and a second bandwidth allocation for receiving network joining messages from nodes that are not joined to the network. The second bandwidth allocation is also used for receiving data messages from nodes operating in the blink mode. Thus, in response to receiving a message that was transmitted from a blink node to a canopy node using the second bandwidth allocation, the network manager identifies the message as a data message and provides the data from the message to a host application.

Abstract: In one embodiment, a method includes receiving playback statuses from a first user computing device and a second user computing device that are in a synchronous presentation session. Content presented on the first and second user computing devices may be determined to be out of synchronization. User behavioral rules associated with the first user computing device may be accessed. The user behavioral rules may be learned based on past behavior of the first user in the synchronous presentation session. A synchronization message may be generated to send to the first user computing device based on the user behavioral rules. The synchronization message may include instructions for the first user computing device to perform an action to cause the content being presented by the first user computing device to be synchronized with the content being presented by the second user computing device.

Abstract: A battery system monitor includes cell measurement circuits (CMCs) that each measure a voltage at or current through a pair of terminals of a respective associated battery module from among a plurality of plurality of battery modules in a battery system. Wireless communication transceivers (WCTs), each associated with a different CMC, transmit voltage or current measurement information of the associated CMC across a wireless communication link. A controller receives the voltage or current measurement information from the wireless communication transceivers for monitoring the state of operation of the battery system. Battery system monitoring is improved through synchronization of clocks in different CMCs or WCTs to enable synchronous sampling of multiple battery modules, through systems for determining relative positions of battery modules in a series coupling of battery modules between terminals of the battery system, and through improvements to the reliability of wireless communication.

Abstract: In a wireless mesh network having multiple network managers, the network managers maintain network security through the use of encryption keys and packet counters. To ensure that each network manager can authenticate communications with any node of the network, the authentication data is replicated in a disjoint manner in all network managers. Advantageously, network reliability is assured by providing redundant managers that can seamlessly maintain network operation even if multiple network managers fail; newly joining managers can obtain full authentication data for the network upon joining; and network throughput is increased by ensuring that any of the multiple managers can authenticate the communications of any network node. The disjoint replication of the authentication data across all network managers is performed with low data-rate manager-to-manager packets propagated through the network.

Abstract: In one embodiment, a method includes connecting two or more user computing devices to provide a synchronous presentation session. Each user computing device may present digital content through an instance of a third-party application associated with a third-party content producer. If one or more of the user computing devices falls out of synchronization with one or more other devices, a synchronization message may be sent to the out of synch device(s), whereby the synchronization message may cause the presentation of digital content across all of the devices to be synchronized.

Abstract: The stability of a channel in a wireless network is evaluated at a node. Upon transmitting a packet from the node on a network channel, a first counter associated with the channel is incremented. Upon receiving an acknowledgment packet responsive to the transmitted packet, a second counter associated with the channel is incremented. A stability metric for the channel is computed based on values stored in the first and second counters. Additionally, interference on a channel of the network is measured at a node. Upon determining that no packet is received during a predetermined time-period on the channel, a received signal strength (RSS) is measured on the channel at an end of the predetermined time-period. Alternatively, upon determining that a packet is received during the predetermined time-period on the channel, the RSS is measured on the channel following completion of the transmission of the packet on the channel.

Abstract: A network manager of a wireless mesh network is configured to selectively enable or disable communication services provided between devices over the network. The selective enabling or disabling of services may be based on the monitoring and enforcement of license terms set according to license information embedded within the wireless network node(s) or access point(s) of the network. In operation, the network manager retrieves the license information from the node(s) and/or access point(s) of the network, and establishes license terms based on the retrieved license information. In turn, the network manager selectively enables or disables network services, such as by throttling communications relayed between the user application and the nodes, or between nodes, if the license terms are not respected.
