Systems and methods for alerting personnel (e.g., workers, emergency responders, pedestrians, observers, etc.) that a vehicle (e.g., car, truck, watercraft, etc.) has entered into, or crossed a boundary of, a protected area or zone.

Systems, methods, apparatuses, and technologies for deploying and operating a drone to present one or more alerts and / or capture sensor data in connection with a vehicle. Drones herein can be deployed and operated to present visual alerts, audible alerts, and / or to deploy one or more alert indicators at different locations. The presentation and / or deployment of alerts by the drone can be used to increase visibility for a vehicle that is at least partially disabled. In addition, sensor feedback from the drone can be used to select a position for the drone to present alerts and / or to facilitate operation of the associated vehicle that is at least partially disabled. Drones can also be deployed and operated to obtain sensor feedback in response to particular conditions being encountered by a vehicle.

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.

The invention relates to a method for operating a signal luminaire (1) for traffic areas, wherein a position sensor (2) is used to capture position data (3) at predefined time intervals and an illumination pattern selection device (4) applies an illumination pattern (6) to an illumination device (5) depending on the position data (3). In order to configure a method and a signal luminaire of the type described in the introduction so as to increase weather resistance and mechanical loading capacity and at the same time simplify glare-free illumination pattern selection for emergency services personnel with protective equipment, the invention proposes that the position data (3) are processed by a gesture detection device (7) to form gesture data (8) and by a transport detection device (9) to form transport pattern data (10), wherein depending on the gesture data (8) and the transport pattern data (10), an illumination pattern (6) is selected from an illumination pattern memory (11) in order to be applied to the illumination device (5).

The present invention relates to the field of artificial intelligence technology, and in particular to an abnormal activity monitoring method and device based on artificial intelligence. The method comprises: generating a first association mapping diagram for projecting a monitoring field corresponding to each monitoring device based on campus building and road planning parameters combined with the setting position of a monitoring device; obtaining abnormal moving targets captured by multiple monitoring devices during night patrols, and updating the position information of the abnormal moving targets in real time based on the first association mapping diagram; sending an early warning execution instruction to a drone so that the drone calling device performs a call attendance task; the application first constructs a monitoring area mapping diagram based on an existing monitoring device to achieve real-time tracking of abnormal targets across cameras, and then dispatches a corresponding calling drone for remote calling, which greatly reduces the number of related security personnel and reduces personnel costs. At the same time, intelligent automatic monitoring can also effectively avoid monitoring omissions caused by human negligence.
