Abstract: A system including a LiDAR system of an autonomous vehicle. The LiDAR system includes at least one light emitter and at least one light detector to generate analog output signals based on reflected pulses of light. A comparator receives the analog output signals from the light detector and generates digital output signals based on the analog output signals and a threshold. A controller receives a first digital output signal of the digital output signals from the comparator based on the threshold, adjusts the threshold, receives at least one further digital output signal of the digital output signals from the comparator based on the threshold as adjusted, and/or determines at least one aggregation based on the first digital output signal and the further digital output signal(s).

Abstract: A system including a first unit configured to: receive a LiDAR output signal, compare a time-delayed LiDAR output signal to the LiDAR output signal, and provide a digital output signal, and a second unit configured to generate LiDAR data including a distance and an amplitude based on the digital output signal.

Abstract: Systems, methods, and computer-program products for a dynamic detection threshold for a sensor of an autonomous vehicle are disclosed. A system may include a LIDAR system of an autonomous vehicle. The LiDAR system may include at least one light emitter and at least one light detector to generate analog output signals based on reflected pulses of light. A comparator may receive the analog output signals from the light detector and generate digital output signals based on the analog output signals and a threshold. A controller may receive a first digital output signal of the digital output signals from the comparator based on the threshold, adjust the threshold, receive at least one further digital output signal of the digital output signals from the comparator based on the threshold as adjusted, and/or determine at least one aggregation based on the first digital output signal and the further digital output signal(s).

Abstract: A signal delay component may be configured to receive a LiDAR output signal including an analog waveform from a LiDAR system, and provide a time-delayed LiDAR output signal including a time-delayed analog waveform. A differential comparator may be configured to receive the LiDAR output signal including the analog waveform and the time-delayed LiDAR output signal including the time-delayed analog waveform, and to provide a digital output signal. A processor may be configured to generate LiDAR data including a distance associated with the LiDAR output signal and an amplitude associated with the LiDAR output signal, the distance being based on a first time associated with a rising edge of the digital output signal, and the amplitude being based on a time difference between the first time associated with the rising edge of the digital output signal and a second time associated with a falling edge of the digital output signal.

Abstract: A system and method for transmitting data using an autonomous vehicle's LIDAR system. The autonomous vehicle may transmit the data by disengaging the LIDAR system's transmitters and receivers from operating to detect external objects. The autonomous vehicle may also rotate the LIDAR system to locate one of a plurality of receivers external to the autonomous vehicle. Data stored within the autonomous vehicle may then be transmitted to an external system using a light-based communication path established between at least one of the LIDAR system's transmitters and an external receiver. The LIDAR system's transmitters and receivers may then be re-engaged so as to be operable to detect external objects.
