  • Patent number: 12052336
    Abstract: A circuit and a method for removing spread spectrum are provided. The circuit includes a data clock recovery module and a clock extraction module that are connected. The data clock recovery module performs clock recovery on an input signal carrying spread spectrum information to obtain a parallel clock signal and a first signal, where the parallel clock signal includes frequency information and phase information, and the first signal includes the frequency information. The clock extraction module divides a frequency of the parallel clock signal to obtain a reference clock signal; acquires a feedback clock signal based on the first signal; acquires a de-spread clock signal based on the reference clock signal and the feedback clock signal, where the de-spread clock signal includes the phase information and does not include the frequency information; and divides a frequency of the de-spread clock signal to obtain an output clock signal.

  • Patent number: 11463764
    Abstract: A method and a system for automatically adjusting intensity of a signal outputted by an HDMI transmitter are provided. With the method, a length of an HDMI transmission line between the HDMI transmitter and an HDMI receiver is determined. A swing amplitude and a pre-emphasis intensity of the signal outputted by the HDMI transmitter are determined based on the length of the HDMI transmission line and a frequency of the signal outputted by the HDMI transmitter. An HDMI output drive circuit is configured based on the swing amplitude and the pre-emphasis intensity.

  • Publication number: 20210164797
    Abstract: A method, for detecting a position change of a lane marker, includes: determining, based on a first measurement data of a distance between the lane marker and a reference marker on a road that is obtained from a first road data collected via a high-precision device at a first time point, a first set of changed regions between the lane marker and the reference marker in which the distance has changed; determining a second set of changed regions between the lane marker and the reference marker in which the distance has changed based on a second measurement data of the distance that is obtained from a second road data collected via a low-precision device at a second time point after the first time point; and detecting the position change of the lane marker between the first time point and the second time point.

  • Patent number: 10484506
    Abstract: Existing program code, which is executable on one or more computers forming part of a distributed computer system, is analyzed. The analysis identifies log output instructions present in the program code. Log output instructions are those statements or other code that generate log messages related to service requests processed by the program code. A log model is generated using the analysis. The log model is representative of causal relationships among service requests defined by the program code. The log model can then be applied to logs containing log messages generated by execution of the program code, during its normal operation, to group log messages for improved analysis, including visualization, of the performance and behaviour of the distributed computer system.
