  • Patent number: 10680899
    Abstract: A wireless network can perform a topological mapping through its gateway, which sends a multicast message over the wireless network to every node of a network. Each of the nodes on the network, on receipt of the multicast message, can transmit a one-hop multicast message containing a topological ping to its neighboring nodes. A neighboring node receiving a topological ping will store information relating to the link quality between the sender and neighboring nodes. After network traffic related to the topology discovery has quieted, the neighboring nodes sends the stored information to the gateway, without any processing by the node which sent the topological ping. All nodes may also implement a randomized delay both before sending the topological ping, and/or before sending the stored information to the gateway, to minimize the opportunity for data collision of messages relating to topological discovery.

  • Patent number: 10192373
    Abstract: In a tag identification system, active tags are configured to emulate at least one passive tag so that existing passive identifications systems, such as passive radio-frequency (RFID) systems or near field communication (NFC) systems, can be retrofitted to operate with the active tag without having to make expensive hardware updates to the readers within the system. The active tag permits continuous monitoring of its movement or status, as may be desired, regardless of its proximity relative to the readers thereby allowing a system to capture more data regarding the tag's location and use. In addition, the active tag may be compatible with different passive identification systems thereby permitting it to operate with disparate passive identification systems and obviating the need of the user to carry multiple passive tags.

  • Patent number: 9763062
    Abstract: In a system and method for upgrading software in a wireless mesh network, a first node in the network sends a first multicast request to a plurality of other nodes in the network that are in radio range of the first node. The first multicast request queries whether the other nodes are running a software version older than the software version and device type currently running in the first node. The first node then selects a node to upgrade and sends a request asking if any other nodes have already claimed that node. The first node then updates the nodes only if they have not been claimed for update by another node. In upgrading the claimed nodes, the first node copies to the claimed nodes the software it is currently executing in its internal flash memory thereby creating a clone, and does not store any additional copies of the updated software.

  • Patent number: 9654933
    Abstract: A wireless network has a plurality of nodes that are configured to communicate electrical signals via a backhaul channel in which messages hop from node-to-node through the network. The nodes have optical transmitters for communicating with tags via an optical channel that is time division multiplexed (TDM) among the nodes of the network. The nodes are configured to transmit an electrical synchronization signal via the backhaul channel and to synchronize transmissions for the optical channel based on the electrical synchronization signal. Thus, use of the backhaul channel to communicate the synchronization signal leverages the existing framework of the network in order to synchronize the optical transmitters without requiring specialized synchronization circuitry, and a robust TDM algorithm can be implemented for the optical channel with relatively low complexity and costs.
