  • Patent number: 11835305
    Abstract: The present invention discloses an openable and closeable condensing apparatus, which is particularly applied in a two-phase liquid immersion cooling system. When servers start to operate, a large amount of heat will be dissipated from servers. The coolant is vaporized into a rising coolant vapor by absorbing heat dissipated from servers. Upon contact with a condenser, the coolant vapor is condensed back into a cooling liquid that is returned to the coolant-containing tank. By the heat exchange cycle in which heat dissipated from serves is absorbed by the coolant, servers can be maintained at a normal working temperature. However, in the process of condensation, the rising coolant vapor tends to scatter in all directions resulting in a failure to condense all of the coolant vapor. Therefore, the uncondensed coolant vapor will cause the pressure in the system to gradually rise, which eventually leads to an ineffective cooling of servers.

    Abstract: In one instance, a multistage microchannel condenser is provided for use as an aspect of a heating, ventilating, and air conditioning (HVAC) system. The multistage microchannel condenser includes at least two pluralities of flat tubes having microchannels, each associated with a different refrigeration circuit, that are interspersed so that when only one refrigeration circuit is operational, the multistage microchannel condenser still does not have any substantial thermal dead spots. Manifolds are used on each end of the multistage microchannel condenser to fluidly couple members of the at least two pluralities of flat tubes such that the refrigerant in each refrigeration circuit remains separated while still using a majority of the area of the face of the multistage microchannel condenser. Other aspects are presented.

  • Patent number: 11595230
    Abstract: Embodiments relate to including information in a data packet transmitted by a transmitting integrated circuit (e.g., SOC) to account for a time delay associated with an unsuccessful arbitration attempt to send the data packet over a multi-drop bus. The unsuccessful arbitration attempt by the integrated circuit may delay the transmission of the data packet until the multi-drop bus becomes available for the integrated circuit to send the data packet. The data packet includes a data field to include time delay information caused by the unsuccessful arbitration attempt. A receiving integrated circuit may determine the time that the data packet would have been sent out from the transmitting integrated circuit absent the unsuccessful arbitration attempt based on the delay information. Embodiments also relate to a synchronization generator circuit in an integrated circuit that generates timing signals indicating times at which periodic events occur at another integrated circuit.

  • Patent number: 11481851
    Abstract: A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a time-based token based on a time duration specified for a meter. The time-based token indicates the time duration for the meter. The time-based token is further generated based on an identifier of the meter. The headend system transmits the time-based token to the meter via at least a mesh network. After receiving the time-based token, the meter validates the time-based token to determine that the time-based token is generated for the meter based on information related to the identifier of the meter. If the meter determines that the time-based token is valid, the meter connects premises associated with the meter to a resource distribution network for at least the time duration specified in the time-based token.
