  • Patent number: 12294963
    Abstract: A network includes an intermediate node to communicate with a child node via a wireless network protocol. An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

  • Patent number: 12261835
    Abstract: Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key.

  • Patent number: 12255783
    Abstract: An algorithm for the promotion of terminal nodes to switch nodes in a PLC network reduces overall network overhead and collisions, while ensuring the appropriate selection of a switch node and minimizing the number of levels in a PLC network. It also ensures that the terminal nodes with appropriate signal-to-noise ratios (SNRs) are promoted. It is desirable to have a network with fewer levels. The disclosed approach favors the nodes that are closer to the DC to promote them as switch nodes. This is achieved by waiting for a smaller number of PNPDUs for a node that is closer to the DC in comparison to a node that is farther away from the DC.

  • Patent number: 12226834
    Abstract: A method for laser-induced growth of nano-units to form oriented, chiral, and complex structures is provided. Through a laser-induced photochemical reaction, a metal precursor undergoes photolysis to produce inorganic nanoparticles, and these nanoparticles are orientally deposited on a substrate along a polarization direction in a linearly polarized laser to form fusiform nano-units. Through mixed polarized light generated by a vortex plate, the nano-units can grow rapidly and form a specific arrangement to obtain special three-dimensional (3D) nanostructures with chiral features and complex patterns. This method can be implemented in a room temperature environment, has the characteristics of simple operation, short reaction time, high repeatability, long storage time, low cost, and controllable orientations and sites, and shows promising application prospects in the fields of optical devices, chiral catalysis, sensing, integrated circuits, and the like.
