  • Patent number: 12270952
    Abstract: A distance measurement system includes a light transmitter to generate a modulated light signal, a light sensor to generate measurement signals from reflected light among four quad phase angles with respect to a phase of the generated light signal, and a controller. The controller selects a first set of quad phase angles, and generates first measurement signals at the quad phase angles of the first set. Based on the first measurement signals, the controller computes a first phase angle between the generated light signal and the reflected light signal, generates a second set of quad phase angles based on the first phase angle, and generates second measurement signals at the quad phase angles of the second set. Further, based on the second measurement signals, the controller computes a second phase angle between the generated light signal and the reflected light signal and calculates a distance using the second phase angle.

  • Patent number: 12273351
    Abstract: According to some implementations, context-based information is provided. The method can establish a first context for a user to start a process of correlation of information from multiple sources. The method can then authorize the user to access information from one or more sources of information. The method can request the first information from the one or more sources of information based on the first context. Based on the first information received from the one or more sources of information, the method can revise the first context to generate a second context. The method can use the second context to correlate second information from the one or more sources of information. The method can filter the second information for the user to determine a relevant subset of information. Eventually, the method can send the relevant subset of information to a client device associated with the user.
