Abstract:

Various embodiments provide methods for controlling landings of a UAV in a landing zone including a plurality of landing bays. Various embodiments include a method implemented on a computing device for receiving continuous real-time sensor data from a transceiver and from sensors onboard the UAV, and detecting a target landing bay within the plurality of landing bays within the landing zone that is available for landing based on the continuous real-time sensor data. Orientation and position coordinates for landing in the target landing bay may be calculated based on the continuous real-time sensor data. Information regarding positions and flight vectors of a plurality of autonomous UAVs may be obtained, and a flight plan for landing in the target landing bay may be generated based on the orientation and the position coordinates, positions and flight vectors of the plurality of autonomous UAVs and a current orientation and position of the UAV.

Abstract:

Methods and devices of various embodiments provide enhanced location services by leveraging a system of beacon devices each broadcasting data that is useful in calculating locations and report of the trustworthiness of neighbor beacon devices. Various embodiments include a method performed by a beacon device that may include obtaining location data using a first functionality, evaluating sensor data to identify a breach of trust condition at the beacon device, generating authentication data that indicates any identified breach of trust condition, receiving one or more neighbor beacon broadcast messages using a second functionality, determining whether the one or more neighbor beacon broadcast messages include trustworthy location data, and broadcasting an outgoing broadcast message that includes the obtained location data, timing data, the generated authentication data, and data indicating whether the one or more neighbor beacon broadcast messages include trustworthy location data.

Abstract:

Methods, devices, systems, and non-transitory process-readable media for evaluating operating conditions of an autonomous aircraft before performing a mission by executing brief near-flight testing maneuvers at a low elevation. A processor of the autonomous aircraft may receive near-flight testing maneuver instructions that indicate a near-flight testing maneuver to be executed by the autonomous aircraft. The processor may control motors to cause the aircraft to execute a near-flight testing maneuver within a testing area, obtain data indicating stability and performance information while executing the near-flight testing maneuvers, and take an action in response to the obtained data. Actions may include adjusting a position of a payload, a weight or a portion of the aircraft based, and adjusting a flight plan. The near-flight testing maneuvers may include a sequence of moves for testing stability of the aircraft and payload executing a flight path under anticipated flying conditions.

Abstract:

Various embodiments for conducting proxy teaching for learning devices within a decentralized system, including an embodiment method with operations for obtaining, by a teacher signaling device, objectives data related to activities of one or more of the learning devices, generating, by the teacher signaling device, teaching routines based on the obtained objectives data, and broadcasting, by the teacher signaling device, teaching signals configured to teach one or more of the learning devices based on the generated teaching routines. Other embodiments may obtain objectives data by requesting reflex information from the learning devices or intercepting event report messages transmitted by the learning devices. Other embodiments may include broadcasting discovery signals to identify nearby learning devices and modifying teaching routines when objectives of the generated teaching routines cannot be achieved. Other embodiments may include transmitting an authorization request to a user device to determine whether to broadcast teaching signals.

Abstract:

Various embodiments for a learning device to improve the performance of learned behaviors by requesting information from proximate devices within a decentralized system including a learning device method for generating, by the learning device, a first pattern based upon one or more obtained events, determining whether the first pattern exactly matches a known second pattern, determining whether the first pattern matches the second pattern within a predefined threshold in response to determining that the first pattern does not exactly match the second pattern, identifying a missing event of the second pattern in response to determining that the first pattern matches the second pattern within the predefined threshold, and broadcasting, by the learning device, a message requesting data related to the identified missing event. Data received in response to request messages may be used to recognize that the known second pattern is matched.
