  • Publication number: 20210051114
    Abstract: Systems and methods of network packet switching use a table representation of a trie data structure to identify a timestamp (TS) range (or time range) for a received packet based on the packet timestamp (TS). The trie data structure is programmed with a plurality of predetermined time ranges. Each node in the trie data structure corresponds to a TS prefix and is associated with a corresponding predetermined time range. A search engine in the network switch can use the packet TS as a key to traverse the trie data structure and thereby matching the packet TS to a predetermined time range according to a Longest Prefix Match (LPM) process. Provided with the TS ranges of the incoming packets, various applications and logic engines in the network switch can accordingly process the packets, such as determining a new destination IP address and performing channel switch accordingly.

  • Patent number: 10749369
    Abstract: An electronic lock structure using a wireless charging device contains a power supply unit and an electronic lock unit. The power supply unit includes a variable-frequency drive and an AC/DC transformer. The electronic lock unit includes a battery and a rectification circuit, wherein the rectification circuit electrically outputs power of alternative current by way of a power receiving coil. When the power receiving coil is close to the power output coil, the power supply outputs the power to the electronic lock unit by using magnetic flux and to supply the power to the battery, thus charging the battery. When the power receiving coil is away from the power output coil, the power output coil does not conduct the power to the power receiving coil.

  • Publication number: 20200166200
    Abstract: Disclosed is a modular housing for drivers used for LED lamps. The housing includes connectors for AC in from a power source, DC out to the lamps, and also has connectors allowing for control lines to be received from a control box. The housing includes an arrangement for creating two opposite stacks of drivers. The fronts of the drivers are cooled by circulating air through the space between the stacks, and heat is also dissipated through the side walls of the housing, which acts as a heat sink. The number and specifications of the drivers in the housing are configured such that every module is able to serve a number of LED lamps.

  • Patent number: 10554515
    Abstract: A customer premises network access device includes a housing and a network interface unit at least partially disposed therein, for communicating with a data network and providing access to the data network to a user. The customer premises network access device also includes a processing unit disposed in the housing and connected to the network interface unit. The processing unit is configured to determine an aggregate amount of data associated with the network interface unit over a predetermined time period, and to determine a data value based on the determined aggregate amount of data. An exterior-facing display viewable to the user from outside the housing receives the data value from the processing unit, and displays an indicium based on the display value to the user.
