Aspects of the present disclosure involve systems, methods, and devices for fault detection in a Lidar system. A fault detection system obtains incoming Lidar data output by a Lidar system during operation of an AV system. The incoming Lidar data includes one or more data points corresponding to a fault detection target on an exterior of a vehicle of the AV system. The fault detection system accesses historical Lidar data that is based on data previously output by the Lidar system. The historical Lidar data corresponds to the fault detection target. The fault detection system performs a comparison of the incoming Lidar data with the historical Lidar data to identify any differences between the two sets of data. The fault detection system detects a fault condition occurring at the Lidar system based on the comparison.

Methods, systems, and apparatuses are described that are configured for determining a path of an apparatus, engaging a motor to cause the apparatus to proceed along the path, receiving one or more of LIDAR data, ultrasonic data, or optical flow data, determining, based on one or more of the LIDAR data, the ultrasonic data, or the optical flow data, one or more objects in the path of the apparatus, and engaging the motor to cause the apparatus to avoid the one or more objects.

A light receiving element includes: a first tap; a second tap; a first photoelectric conversion unit configured to detect a charge generated by photoelectric conversion according to a light amount of incident light in accordance with a voltage applied to the first tap; a second photoelectric conversion unit configured to detect a charge generated by photoelectric conversion according to a light amount of the incident light in accordance with a voltage applied to the second tap; a plurality of accumulation units configured to accumulate the charges generated by the first photoelectric conversion unit and the second photoelectric conversion unit; a plurality of transmission units configured to transmit the charges generated by the first photoelectric conversion unit and the second photoelectric conversion unit to the plurality of accumulation units; and a calculation unit configured to execute calculation based on the charges accumulated in the plurality of accumulation units.

A management system includes a monitoring device and at least one detection device. The monitoring device projects detection light for detecting a monitoring target, and identifies the monitoring target based on a detection pattern of reflected light of the detection light. The detection device is installed on the monitoring target. The detection device receives the detection light projected by the monitoring device, and reflects the detection light at a timing set to the detection device in a predetermined period starting from a timing at which the detection light is received.

A receiving arrangement for receiving light signals and a method for receiving light signals are proposed, wherein a light receiver is provided, which serves for receiving the light signals and converting them into electrical signals. Furthermore, an evaluation circuit is provided, which, depending on the electrical signals and a start signal for the emission of the light signals, determines a distance between the receiving arrangement and an object at which the light signals are reflected. A characterizing feature is that the light receiver has a first group of light-receiving elements, which has a higher sensitivity for receiving the light signals than at least one further group of light-receiving elements, wherein the first and the further groups are ready for reception at different times.
