Abstract: An autonomous RAID data storage device locking system includes first RAID data storage device(s) that store data included in a data stripe, and that are coupled to a second RAID data storage device. The second RAID data storage device receives a command to perform a data update operation on a subset of data included in the data stripe, and transmits a locking request to each first RAID data storage device. When the second RAID data storage device receives a locking confirmation that indicates that each first RAID data storage device is locked, it completes the data update operation on the subset of data included in the data stripe. The second RAID data storage device then transmits an unlocking request to each first RAID data storage device to cause them to unlock, and transmits a completion communication that indicates that the data update operation has been performed.

Abstract: A mixed reality image capture system performs actions to guide a user toward a predefined vantage point to ensure image capture from a consistent vantage point. The system includes a mixed reality frame alignment tool that controls projection optics to project a first virtual target and a second virtual target within a camera field-of view. The first virtual target is projected at a first location within the camera field-of-view that is fixed relative to an identified real-world anchor object and the second virtual target is projected at a second location within the camera field-of-view that is fixed relative to a position of the camera. As the user moves the camera relative to the real-world anchor object, the mixed reality frame alignment tool dynamically updates a position of the second virtual target to mirror movements of the camera.

Abstract: A blockchain-based configuration profile provisioning system includes a client device that generates and broadcasts a blockchain transaction that identifies the client device and is directed to a blockchain address that is included in a blockchain. A blockchain device receives the blockchain transaction broadcast by the client device, executes a smart contract associated with the blockchain address, and determines that the execution of the smart contract has provided an indication that the client device identified in the blockchain transaction is authorized to receive a configuration profile. In response, the blockchain device causes a configuration profile token to be generated and transmitted. A configuration profile system receives the configuration profile token and, in response, retrieves and transmits the configuration profile to the client device.

Abstract: A RAID storage multi-step command system includes a RAID storage system coupled to a RAID storage controller device. The RAID storage controller device identifies a RAID storage system configuration of the RAID storage system and, based on the RAID storage system configuration, generates a first multi-step command definition file for a first RAID storage device in the RAID storage system, and transmits it to the first RAID storage device.
