Abstract: Disclosed are techniques that use devices with corresponding identity wallet applications that execute on an electronic processor device of the devices, and which identity wallets store identity information and encrypt the stored identity information. A distributed ledger system, and a broker system that interfaces to the wallet and the distributed ledger are used for various information exchange cases pertaining to access to facilities. In particular, disclosed is a registration process to register an identity wallet with a facility.

Abstract: The present disclosure is directed to a lift system for a rotor blade of a wind turbine. The lift system includes a lifting device having at least one cradle. The cradle has a profile that corresponds to at least one of the exterior surfaces of the rotor blade so as to support at least a portion of the rotor blade. Further, the lift system includes a positioning assembly having at least one distance sensor mounted to the hub and at least one visual sensor mounted to the lifting device. Thus, the distance sensor is configured to identify a distance from the hub to the lifting device and the visual sensor is configured to identify a position of the rotor blade in the cradle.

Abstract: A power supply system and method include multiple power conversion units (PCUs) with independent power generation control and a PCU-to-PCU regulation of power, handoff control system to transfer control of power regulation to a load among the PCUs. The multiple PCUs maintain independent power generation control to collectively provide power to the load and handoff regulation of the power to the load from one PCU to another PCU. The term “handoff” refers to communication between PCUs that affects a transfer and acceptance of regulation of power control. The independent PCU power generation control with singularly located but transferable control of the regulation of power provides a flexible dynamic power supply.

Abstract: Disclosed are techniques that use user devices and a server system to process employee generated requests to allow guest access registration. A server system receives a request for guest registration and the server system sends in response to the request a message to a guest user device with the message including a request for user credentials. The user credentials are supplied from a user's PII wallet carried by the user. The server system receives from an employee user device a verification of the guest registration, produces an access policy for the guest user device and causes the produced policy and guest credentials to be stored in a distributed ledger system.
