Abstract: An insertion system for inserting a bushing assembly defining first and second end configurations into a housing opening defined by a structural member comprises a brace assembly, an actuator assembly, and a drive plate. The brace assembly comprises a brace rod, an anchor member defining an anchor edge surface and a spacing portion, and a brace nut. The actuator assembly comprises an actuator housing and a drive member. Displacement of the drive member causes displacement of the bushing assembly through the drive plate such that the anchor edge surface acts on the structural member and the drive plate displaces the bushing assembly into the housing opening towards the anchor member. The spacing portion of the anchor member is configured to engage the second end configuration of the bushing assembly to prevent further displacement of the bushing assembly when the bushing assembly is in a desired position.

Abstract: A system having components coupled to an aircraft in operation processes sensor-derived data, performs a localization cross-checking procedure, and dynamically generates updated analyses of the position and orientation of the aircraft. Based on the updated analyses, the system can generate instructions for flight control of the aircraft and can update flight control instructions as new data is received and processed. The system functions to reduce the “worst-case” bounds on a localization estimate for the aircraft to a low enough level that is appropriate for completing a flight operation.

Abstract: Described herein are techniques to ensure a user using an external device is authorized to connect and connecting to a correct implantable medical device using a wireless communication protocol. A request for authorization is sent to the external device from the implantable medical device, and the authorization can be provided by an authorization pulse sent using the implantable medical device charger over the inductive link between the charging device and the implanted device. The authorization pulse can be trusted because the inductive link is short range, ensuring the patient is aware of the connection to the implanted device. Once the implanted device receives the authorization pulse, it may finalize the pairing over the first connection.
