The embodiments of the present disclosure are generally directed to zero-duplicate direct-memory-access data buffer management in a data communication interface and are particularly directed to an efficient and collaborative buffer management for data transmission and synchronization between a plurality of data sources (data producers) and a data destination (data consumers) via the data communication interface. In one example, the disclosed buffer management approach combines zero-duplicate buffers, priority-based buffer allocation, priority-based data synchronization, and a collaborative communicated buffer holding time to manage the direct-memory-access and release of buffered data in a real-time and continuous dataflow producer-consumer system.

Efficient direct-access buffer management in a data communication

An optical system, a method and an apparatus for diagnosing the optical system are provided. The optical system includes a laser sensor, and a tubular sleeve surrounding the laser sensor and configured to move upwards or downwards relative to the laser sensor to cover or expose the laser sensor. The method includes: driving the tubular sleeve to cover the laser sensor to form an enclosed chamber; filling the enclosed chamber with fluid; controlling at least one of the one or more transmitters to emit an optical signal into the fluid; controlling at least one of the one or more receivers to detect a scattered signal of the optical signal; determining whether the at least one of the one or more transmitters or the at least one of the one or more receivers has a fault based on the scattered signal.

A mounting base for sensor is provided. The mounting base comprises: a body having a top surface; a mounting portion located on the top surface of the body, the mounting portion is configured for mounting a sensor; and at least one airflow generating component, the airflow generating component is configured for forming at least one airflow on a side of the sensor mounted on the mounting portion.

Mounting base for mounting sensors

An object identifying method is provided. The method comprises: acquiring detection data associated with a detection signal, wherein the detection data comprises a transmission time of the detection signal transmitted by a LiDAR device; acquiring reflection data associated with a reflection signal of the detection signal reflected by an object at an object distance from the LiDAR device, and the reflection data comprises a receipt time of the reflection signal and an intensity of the reflection signal; and determining whether the object is an interference by comparing the intensity of the reflection signal with a distance-dependent threshold intensity.

Method and device for identifying objects detected by a LiDAR device

This disclosure describes example methods and apparatus for automatic identification of performance degradation in a Light Detection and Ranging (LIDAR) device and for providing appropriate precautions in the forms of operation interventions, warnings/alerts, and initiation of maintenance procedures. The performance degradation is derived from various performance indicators obtained by analyzing echo measurement samples detected by the LIDAR device.
