Abstract: A system and method for detecting space debris which is based on measurements of broadband non-thermal radiation and/or light emitted by either sparks or the expansion of the plasma-fragments cloud generated during high-speed collisions of solid materials. The method is based on the concept that broadband nonthermal radiation and/or light can be used to detect the formation of new debris and for tracking debris clouds. The emission of broadband nonthermal radiation and/or light is based on theoretical and observational evidence that the collision of particles of solid materials with each other transfer enough charge to create electric fields large enough to produce small electric discharges or sparks and that the expansion of the plasma-fragments cloud generated by collisions at orbital velocities produce thermal and non-thermal electromagnetic signals.

Abstract: Proximity sensors, e.g., Bluetooth® sensors, are installed in a vehicle. Each sensor determines/estimates approximate distance from itself to a user mobile device. In response to the distance increasing above a predetermined distance departure limit, as the sensors communicate to a vehicle control system (VCS) through Bluetooth® or similar links, the VCS causes predetermined departure actions to be performed, such as locking the doors, turning off headlights, activating the vehicle's security system, and/or others. In response to the distance decreasing below a predetermined distance arrival limit, as the sensors communicate to the VCS through the link(s), the VCS causes predetermined arrival actions to be performed, such as unlocking the doors, flashing the headlights, beeping the horn, deactivating the security system, and/or others. Hysteresis may be applied to the decisions whether to perform the departure/arrival actions.

Abstract: Techniques are described for controlling an autonomous vehicle (AV) using objective-based inputs. The underlying functionality of an autonomous navigation system can be is exposed via an application programming interface (API) or similar methodology allowing the UAV to be controlled through specifying a behavioral objective, for example, using a call to the API to set parameters for the behavioral objective. The autonomous navigation system can then incorporate perception inputs such as sensor data from sensors mounted to the UAV and the set parameters using a multi-objective motion planning process to generate a proposed trajectory that most closely satisfies the behavioral objective in view of certain constraints. Developers can utilize the API to build customized applications for the AV. Such applications, also referred to as “skills,” can be developed, shared, and executed to control behavior of an autonomous AV.
