An emitter ID ambiguity reduction system includes a Mission Data File Ambiguity Resolution matrix that contains both a) the INTEL-based emitter parameters data necessary to break emitter-by-emitter ambiguities, and b) the action(s) the Electronic Warfare (EW) system is to take to collect that data. Control software is triggered via either external command or per Mission Data File information (such as that contained in the Ambiguity Resolution Matrix). The emitter ID ambiguity reduction system includes Data collection hardware and firmware and Data Analysis OFP software algorithm(s).

Various methods enable a processor of a robotic vehicle to determine when the robotic vehicle has been stolen so that a self-recovery operation may be performed. Determining whether the robotic vehicle has been stolen may include evaluating, by a processor of the robotic vehicle, unauthorized use indicia, and determining that the robotic vehicle is stolen in response to determining that unauthorized use indicia exceed a threshold. Evaluating unauthorized use indicia may include determining whether an Integrated Circuit Card Identifier of a Subscriber Identify Module matches a stored value, determining whether a paired controller is different from a usual controller, determining whether the operator's skill has changed, and evaluating one or more trust factors that are observable features of normal operation.

A method for controlling an unmanned aerial vehicle (“UAV”) includes receiving locking instruction information from a user terminal for locking the UAV. The method also includes transmitting a locking command to a remote control device of the UAV based on the locking instruction information, to instruct the remote control device to lock the UAV based on the locking command.

The present subject matter is related to a safety mechanism that comprises method and system for automatically performing safety operations to prevent crash of an airborne vehicle. When there is a deviation of current airborne vehicle path from predefined airborne vehicle path, the airborne vehicle safety system sends a notification to receive authentication of all aircraft operators in the airborne vehicle, as a safety measure. If the authentication is provided, then the airborne vehicle proceeds along the current path, otherwise control of the airborne vehicle is switched from manual control to automatic control that proceeds along the predefined path. Therefore, the airborne vehicle safety system prevents intentional crash or deviation from the current path. Further, the airborne vehicle safety system unlocks cockpit door of the airborne vehicle when authentication is not received from the aircraft operator in cockpit so that necessary measures can be taken to prevent the crash.

A system for controlling an unmanned aerial vehicle may include a GNSS receiver, a transponder, one or more flight controls, a UAV operation module, a UAV mission module, and a UAV chassis. The system may include an operating area defined within an airspace and an airspace controller, and a transponder key issued to the UAV by the airspace controller. The airspace controller and the UAV may communicate to unlock UAV access of the operating area, including transmitting a transponder ID code for verification to the airspace controller; receiving a read certificate from the airspace controller; transmitting a mission plan to the airspace controller; receiving a mission key from the airspace controller; verifying the mission key via read back transmission to the airspace controller; and receiving a mission plan from the airspace controller in the form of the transponder key, the mission plan unlocking access to the operating area.

In an example, method for locking/unlocking a structure is described. The method includes attaching a first end of a pawl to a support assembly, wherein the pawl comprises a shape memory alloy (SMA) element configured to transition between a first configuration and a second configuration, and wherein the pawl is attached to the support assembly such that a second end of the pawl is movable between a locked position that prevents a rotatable shaft from rotating and an unlocked position that allows the rotatable shaft to rotate, activating the SMA element, thereby causing the SMA element to take on the first configuration and move the second end of the pawl to the locked position, and deactivating the SMA element, thereby causing the SMA element to take on the second configuration and move the second end of the pawl from the locked position to the unlocked position.

An unmanned aerial vehicle (UAV) including a detection device configured to detect that a disassembly operation has been performed on the UAV and a controller configured to determine whether the disassembly operation is an unauthorized disassembly operation, and prohibit the UAV from moving in response to the disassembly operation being the unauthorized disassembly operation, where the detection device is communicatively connected to the controller.

A removable barrier and an aircraft including such a removable barrier. The barrier including a panel configured to block at least partly an opening delimited by a frame, a plurality of straps each connected to the panel and each having first and second ends, for each strap, a first connection configured to connect the first end of the strap and a first edge of the frame at least temporarily, a second connection configured to connect the second end of the strap and a second edge of the frame at least temporarily, at least one folded overlength at the level of at least one of the first and second ends of the strap, at least one breakable connection keeping the overlength folded.

There is provided a system for securing a cockpit from a cabin. A lavatory door has a locking mechanism provided thereon. A latching mechanism is provided on an adjacent structure across an aisle from the lavatory. The locking mechanism is compatible with the latching mechanism to secure the lavatory door in an open position, thereby forming a secure area for entering from the cockpit.

A method for controlling an unmanned aerial vehicle (UAV) includes receiving locking instruction information for locking the UAV; remotely controlling, based on the locking instruction information, a remote control device of the UAV to lock the UAV; and remotely controlling, after controlling the remote control device to lock the UAV, the remote control device to unlock the UAV.
