The present invention relates to an on-board emergency remote assistance and data retrievable system configured to download and retrieve image, audio and video information from the inside and outside of a manned aerial vehicle (MAV) using an on-board unmanned aerial vehicle (UAV), while the MAV is either in the air or crashed. The UAV system comprising at least one drone in coordination with a remote station to automatically locate a distressed MAV while in operation, to track it and provide assistance when possible, wherein the drone being integrated into the MAV. The system of the present invention conclusively prevents the lost or disappearance, and crash of the manned aerial vehicle without a trace.

A protective system to make drones and unmanned aerial vehicles retrievable in an event of a crash. The protective system also reduces damage from impact during a crash. The protective system will deploy automatically or manually in an event of a crash to reduce the physical impact and provide floatation on the surface of a water body. Several onboard location indicating devices for indicating the location of crashed drone or unmanned aerial vehicle are also part of the protective system.

Devices and methods for aiding a large area search for objects. A searcher transmits interrogation signals of long range relative to the return range to be received by a device at the target object. The target device responds with a ping signal modified to be more easily found by means of information contained in the interrogation signal. The information may be in the nature of the received signal or data encoded and embedded. The target device may use a microprocessor to do complex operations using the information from the interrogation signal and other information. Detection of a weak ping is facilitated by such means as being beamed in the direction of the interrogation, arriving at a predictable time, or having parameters adapted to values requested by the searcher. The object is then intercepted with help of the ping or other signals from the device.

An on-board emergency response system for a vehicle include a drone being integrated with a vehicle to become separated only when the vehicle is in trouble or experiencing difficulties. Activation of the drone may be from inside the vehicle or remotely via a communication link. The drone is automatically ejected or activated when abnormal conditions inside or outside the vehicle are detected. The drone may provide a backup communication when needed. Once the drone is ejected from the plane, it then follows the vehicle from above at a predetermined distance. It also sends its location, video and images taken inside and outside the vehicle to the command center. If a disaster is inevitable, the drone then tracks the vehicle all the way to its destination. Since the vehicle's actual location is immediately known to the central command, the rescue team can take off in no time, skipping the search altogether.

A data recording apparatus, data recording system and an orientation determination method thereof is disclosed. The data recording apparatus may include a housing, a wireless communication interface, one or more memories that store executable code; and one or more processors configured to execute the executable code, which causes the one or more processors to: control the communication interface to obtain data from Flight Data Acquisition Unit (FDAU) and store the obtained data in the one or more memories. The obtained data may include one or more of flight data, cockpit data (e.g., cockpit voice data), or cabin data (e.g., cabin voice data). The data recording apparatus may include a detachable attachment means for allowing the data recording apparatus to separate from the airplane in the event of a crash via a passive detachment means.
