  • Patent number: 12363522
    Abstract: A discovery and provisioning method. The method includes: A first device in an unprovisioned state sends a first message through a first antenna, where the first message is used by a second device to discover the first device, and the first message includes a device identifier of the first device; when a distance between the second device and the first device is less than or equal to a preset distance, the second device receives the device identifier sent by the first device; and after being discovered by the second device, the first device performs provisioning by using a second antenna.

  • Publication number: 20230283994
    Abstract: An electronic device includes: a processor; a memory; an antenna, wherein a transmitting distance of the antenna at a first transmit power is a first distance; a transmitting distance of the antenna at a second transmit power lower than the first transmit power is a second distance; wherein the first distance is greater than a preset safety distance, while the second distance is less than that. The electronic device is enabled to perform sending a first message based on a first periodicity by the antenna at the first transmit power, the first message is an encrypted ciphertext; receiving a first response message of a mobile device; sending a second message based on a second periodicity by the antenna at the second transmit power, the second message is an uncrypted plaintext; receiving a second response message of the mobile device; and executing all or a part of a specific function.

  • Publication number: 20220276671
    Abstract: The invention discloses clock management of chips, in particular to the clock domain system of interconnected dies and its management methods. The clock domain systems of the interconnected dies, comprising: global clock domains used to manage interior networks on die of the interconnected dies, standard protocol interface clock domains used to manage standard protocol conversion modules and interface source synchronous clock domains used to manage expansion synchronization controllers across dies. The clock domain systems of the interconnected dies provided by the invention modularize complicated clock networks by isolating each module from the perspective of clocks and simultaneously initiate clock synchronization among all clock domains, which is easy for interconnected network setups.

  • Patent number: 11032122
    Abstract: A multicast delay diagnosis method is provided, where the method includes sending, by a terminal device, a first domain name resolution request to a network node; receiving a first multicast test address returned by the network node; sending a first multicast test join request to the network node by using the first multicast test address, and recording a time point for sending the first multicast test join request; receiving a first packet returned by the network node, and recording a time point for receiving the first packet; calculating, according to the time point for sending the first multicast test join request and the time point for receiving the first packet, a first delay caused when the terminal device joins a multicast test group of the network node; and determining multicast network quality according to the first delay.
