Latest Patents

One of his latest patents is titled "Multi-modal cognitive mechanism for road section recognition." In this invention, a processor receives an audio signal from a road test. The processor processes the audio signal to generate an acoustic spectrum density distribution map to identify at least one road section switching point in a first mode. Additionally, the processor processes a spectrogram of the audio signal to identify the respective road section switching point in a second mode. Furthermore, a machine learning model is employed to predict an expected sound at each frame of the audio signal, calculating the similarity between the expected sound and the actual sound. The identification of the road switching point occurs when the similarity is lower than a pre-set threshold in a third mode. The results from these three modes are combined to obtain a final set of road section switching points.

Another significant patent is "Signal detection and monitoring." This invention provides a method, system, and computer program product for detecting and monitoring a signal. The method includes detecting an alignment point for a periodic signal segment generated by an apparatus being monitored for standard functionality. In response, the apparatus is activated from a period prior to the alignment point to the end point of the periodic signal segment, and a first point of the periodic signal segment is located. Similarly, a second point of an additional periodic signal segment is located. The periodic signal is then normalized based on the results of locating these points.
