  • Patent number: 12332386
    Abstract: A system comprises a photosensor and a controller. A first photoemitter transmits light onto objects at first height, a second photoemitter onto objects at second, lower height, and a third photoemitter onto objects at third, lowest height. The controller causes one of the photoemitters to transmit modulated light and the photosensor to receive reflections from a scene. The controller determines a depth map for the corresponding height based on phase differences between the transmitted and reflected light. In some examples, the system is included in an autonomous robot's navigation system. The navigation system identifies overhanging objects at the robot's top from the depth map at the first height, obstacles in the navigation route from a second depth map at the second height, and cliffs and drop-offs in the ground surface in front of the robot from the third depth map at the third height.

    Abstract: A circuit includes an interference frequency tracking circuit, a PLI synthesizer circuit, and a summing circuit. The interference frequency tracking circuit is configured to track a frequency of an interference signal derived from a target signal, and provide a frequency selection value representing the frequency of the interference signal. The PLI synthesizer circuit is configured to generate, based on the frequency selection value, a correction signal at the frequency of the interference signal, adjust a phase of the correction signal to match a phase of the interference signal in the target signal, and adjust an amplitude of the correction signal to match an amplitude of the interference signal in the target signal. The summing circuit is configured to subtract the correction signal from the target signal.
