  • Publication number: 20240154617
    Abstract: Clock generation circuit generating multiple divided signals satisfying respective desired offsets. A phase locked loop (PLL) is used to generate a PLL output having a frequency which is a desired multiple of that of a reference clock. The circuit divides the PLL output by a corresponding divisor to generate a corresponding divided signal, wherein each divided signal is offset from a common reference by at least an associated desired time offset. The common reference is timed with respect to the reference clock when the reference clock is available and with respect to a time reference signal otherwise. This arrangement is extended to use the internal time reference signal even for the cases where the reference clock is present by blocking the reference clock while the output systems across PLLs are aligned using the internal time reference signal to ensure desired offsets across different PLLs with a small uncertainty.

  • Patent number: 11671504
    Abstract: Collecting and distributing information related to recent content publication activity of an instant messaging (IM) user provides other users in a network with timely, relevant information about people known to the user or within the same social network. A user participating in a social network can quickly and efficiently perceive new information related to other users (referred to as co-users) in a social network by reviewing the co-users' recent content publication activity. A user may be made able to do so without requiring the co-user to send a communication directly to the user regarding the new facts or new content, and also without requiring the user to actively browse or request information about the co-user.

  • Patent number: 11267768
    Abstract: A process for producing olefins by cracking paraffins in the presence of methane. In the conventional steam cracking processes for olefin production, steam is used as a diluent in the feed mixture to the thermal cracker. In the processes provided herein, methane replaces steam as a diluent in the feed mixture to the thermal cracker. Replacing steam with methane as a diluent has a potential for cost savings in the construction and operation of a thermal cracking plant for olefin production. In addition, it leads to a much simpler cracking process compared to the conventional steam cracking technology as in the state of the art.
