The invention provides an AGV-based intelligent reflective cone dynamic laying and recycling system, and relates to the technical field of reflective cone dynamic laying, and the system comprises an AGV transportation platform and a cloud decision system. The width d, the road speed limit vmax and the real-time traffic flow rho of the target road section are obtained; determining a basic layout included angle theta and a layout interval delta d corresponding to the combination of d, vmax and rho; generating a comprehensive feature vector XL; inputting the XL into a preset layout included angle weight and layout spacing weight prediction model to obtain a layout included angle weight lambda1 corresponding to theta and a layout spacing weight lambda2 corresponding to delta d; determining a target laying included angle theta'according to the delta d and the lambda 2, determining a target laying spacing delta d 'according to the delta d and the lambda 2, and sending the theta'and the delta d' to the AGV transportation platform so as to lay the reflective heap according to the theta 'and the delta d' through the AGV transportation platform. The method can enable a laying strategy to continuously approach to an optimal solution, and improves the reliability and the economical efficiency of a protection system for a long time.

A system and method for autonomous distress tracking of an aircraft. An automatic dependent surveillance-broadcast transceiver is configured to transmit an automatic distress transmission. A system controller comprises a distress identifier that is configured to determine when the aircraft is in a distress condition. The system controller is configured to control the automatic dependent surveillance-broadcast transceiver to transmit the automatic distress transmission in response to a determination that the aircraft is in the distress condition. The automatic dependent surveillance-broadcast transceiver and the system controller are contained within a housing attached to the aircraft on an outside of the aircraft.

The present disclosure in one aspect provides technologies for light systems used for roadside emergencies for preventing injuries by providing motor vehicle operators with time to react to emergency situations. In various aspect, technologies provide herein may include structural and electrical components useful in light systems that may serve as visual cues to drivers that a corrective action needs to be taken to avoid further accident and injury. In various aspects, light system technologies are specifically adapted to provide enough warning to oncoming traffic using structural and electrical configurations optimized such that corrective action may be taken in a timely manner.

A warning device that combines a radar module with electronic control technology can accurately detect the velocity and the distance of an object around the warning device and provide dynamic warning (e.g., flashing or buzzing). The radar module, installed in an electronic component box, maintains a given distance from the ground to avoid echo interference from the ground, thereby reducing the noise of the collected point-cloud data. A controller extracts the relative velocity and the location of the object from the point-cloud data, selects dynamically approaching points to determine the relative distance and the direction of the object, and dynamically adjusts the flashing frequency of a warning lamp or turns on a buzzer based on the distance of the object relative to the radar module.

A method for safeguarding a self-driving, damaged vehicle includes independently detecting damage of the damaged vehicle by the damaged vehicle and sending information concerning the damage to a central computing unit, connected with the damaged vehicle, of an operator of the damaged vehicle by the damaged vehicle. Information concerning the damage of the vehicle is sent to a superior authority by the central computing unit. A further central computing unit of an operator of a self-driving further vehicle located near the damaged vehicle is informed about the damaged vehicle by the superior authority. When the further vehicle is moving towards the damaged vehicle, the further vehicle is put into a safeguarding mode by the further central computing unit.
