  • Patent number: 11964991
    Abstract: In a ruthenium complex compound according to the present invention, an NHC ligand has an excellent electron-donating ability to stabilize methylidene species due to the steric interaction between substituents having relatively different sizes. The ruthenium complex compound can improve selectivity when used as a catalyst due to having an asymmetric structure, and the activity of the ruthenium complex compound can be improved by adjusting substituents and additives. Accordingly, the ruthenium complex compound can be used as a catalyst in cross metathesis reactions including ethenolysis to produce desired compounds such as linear ?-olefins at high yield, even under relatively mild conditions.

  • Patent number: 11870399
    Abstract: A receiver for cancelling common mode offset and crosstalk that amplifies a voltage difference between an input signal and a reference voltage to generate first and second output signals and an internal signal, that generates the same third and fourth output signals as the first and second output signals, generates average voltage levels of the third and fourth output signals by using first and second switching elements and low pass filters to output the average voltage levels as first and second feedback signals, and cancels a common mode offset between the first output signal and the second output signal based on a voltage difference between the first feedback signal and the second feedback signal, and that generates a control signal to cancel crosstalk of the internal signal by turning on/off the first and second switching elements connected to the low pass filters.

  • Patent number: 11791791
    Abstract: A receiver includes an amplifier that receives a transmission signal and amplifies a first voltage difference between the transmission signal and a reference signal to generate a first output signal and a second output signal at a first node and a second node. An equalizer is provided, which is connected to the first node and the second node and receives the transmission signal. The equalizer compensates a common-mode offset between the first output signal and the second output signal based on a second voltage difference between an average voltage level of the transmission signal and the reference signal.

  • Publication number: 20100180042
    Abstract: Simulcast flow-controlled data streams is described. In embodiment(s), multicast data streams each communicate data to client devices at a different data rate. A high data rate of a first data stream can be reduced to accommodate a receive data rate of a client device that receives the data slower than the high data rate of the first data stream. A flow control service can monitor the high data rate of the first data stream to determine when the high data rate is reduced to a low trigger data rate, initiate a data stream probe at a probe data rate to determine slow client devices that receive the data slower than the probe data rate, and then demote the slow client devices for communication with a second data stream that communicates the data at a low data rate.
