Abstract: A solar power panel failure search and detect system to search and detect malfunctioning or failed sites of a solar power panel. A search unit is installed in a remotely controllable aerial vehicle. The search unit maintains a constant distance between a solar panel and a failure detector, and maintains the failure detector at an optimum angle. A control unit controls a flight path and a flight angle of the aerial vehicle and controls/regulates an angle of the failure detector, a receiver, a processor, and the search unit. The search unit has an angle sensor, the failure detector, an angle adjuster and an imaging device. The control unit has a transmitter to transmit the search result data.

Abstract: An impact mitigation system for an aircraft and method of deploying the impact mitigation system is disclosed. A state parameter of the aircraft is obtained. The state parameter is used with an aircraft performance model to determine an acceleration capability of the aircraft. A trajectory of the aircraft is predicted using the state parameter of the aircraft and the acceleration capability of the aircraft. A location of an object with respect to the aircraft is determined and the impact mitigation system is deployed when the predicted trajectory indicates a contact with the object at a predicted contact velocity higher than a threshold velocity at a future time.

Abstract: Active airbag vent systems and associated systems and methods are described herein. An airbag system having an active vent configured in accordance with an embodiment of the present technology can include, for example, a first inflator operably coupled to a first hose for inflating an airbag in response to a rapid deceleration event. The airbag system can further include a second inflator operably coupled to a second hose configured to release a vent or seam on the airbag to rapidly deflate the airbag after initial deployment of the airbag.

Abstract: A system and method that reduces the descent velocity of an aerial vehicle, the system including a control system, an inflation device, and a deployable, inflatable cage. The control system detects a descent condition, such as an uncontrolled descent and activates the inflation device to inflate the cage to at least partially encase the aerial vehicle and protect the vehicle during descent and landing. The inflatable cage includes a main fill tube, a perimeter tube, and support tubes. The support tubes are connected between the main fill tube and the perimeter tube, and enable gas to flow from the inflation device through the support and perimeter tubes and into the perimeter tube. A drag inducing material enclosure is connected to the inflatable cage and structured to induce drag to reduce a descent speed of the aerial vehicle.

Abstract: A system for deploying an airbag when an unmanned aerial vehicle (UAV) has failed or is no longer able to sustain flight, comprising a triggering means which releases compressed air into a bag or bags which are configured to expand around the UAV for the purpose of reducing the deceleration forces of the UAV on impact. UAV's are provided that are configured with a system that includes a triggering mechanism that deploys one or more bags when there is a failure or when flight is no longer sustainable.

Abstract: A method of making a flame resistant airbag suitable for use in aviation applications is discussed. A flame resistant fabric for the use in the construction of aviation airbags is woven from a high tenacity continuous polyester fiber substrate. A polyurethane coating is applied to the woven fabric, which has been treated with a flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The resulting fabric complies with Federal Aviation Requirement 25.853 as well as exhibits sufficient high pressure permeability resistance which is measured as a pressure of not less than about 198 kPa after five seconds from an initial inflation and pressurization to about 200 kPa, such as may be encountered in and during an inflation of aviation airbag assemblies.

Abstract: A multicopter (100) having a plurality of propellers (1) is configured to be electrically operated. The multicopter (100) is provided with electric motors (2), at least one main battery (3), a generator (4), an engine (5), and a battery condition detecting section (71). The electric motors (2) drive the propellers (1). The main battery (3) is a first electric power source that supplies the electric power to the electric motors (2). The generator (4) is a second electric power source that supplies the electric power to the electric motors (2). The engine (5) drives the generator (4). The battery condition detecting section (71) detects abnormality of the main battery (3). When the battery condition detecting section (71) detects the abnormality of the main battery (3), the generator (4) supplies the electric power that has been converted from motive power from the engine (5) directly to the electric motors (2).

Abstract: An impact protection apparatus is provided, comprising a gas container configured to hold a compressed gas and an inflatable member configured to be inflated by the gas and function as an airbag of a movable object, such as an aerial vehicle. A valve controls flow of gas from the container to the inflatable member in response to a signal from a valve controller. The valve and valve controller are powered by an independent power source than one or more other systems of the movable object. A safety mechanism may also be provided that, unless deactivated, prevents inflation of the inflatable member.

Abstract: The present invention provides an unmanned aerial vehicle (UAV) such as a rotorcraft and a method of improving the performance thereof. The UAV is equipped with an inflated bag to prevent or alleviate property damage and personal injury caused by a collision between the UAV and a foreign object (e.g. a human being and a pet). The inflated bag in the proximity of a propeller's tip can also disrupt the tip vortex of the propeller generated in UAV operation state. The invention exhibits numerous technical merits such as enhanced operational safety, UAV drag reduction, higher propulsive efficiency, and reduction of UAV vibration level, among others.
