Abstract: Disclosed is a system and method for enterprise authentication. An enterprise cluster includes one or more enterprise appliances employing virtual machines managed by at least one hypervisor. Each virtual machine is associated with a respective virtual Trusted Platform Module (vTPM) secured by the hypervisor. An enterprise key (EK) is provided to the appliances of the enterprise cluster and imported into a vTPM associated with each appliance. When a user authentication request is received by a first appliance, the first appliance obtains a user encrypted key which was previously encrypted by a different vTPM on a different appliance with the same EK. The vTPM then signs a challenge based on decrypting the user encrypted key with the EK, completing the user authentication request.

Abstract: Devices and systems for implementing decentralized custodial wallets are described. The described embodiments advantageously provide private key management, decentralization, and privacy. Embodiments of the disclosed technology further provide an example method that includes receiving, from a user, an input indicative of an instruction that creates a decentralized identifier (DID) associated with a public/private key pair of the user that includes a user public key and a user private key. The method further includes transmitting, to a data registry on a blockchain, public information associated with the user and the user public key, generating (a) a verifiable credential (VC) data structure comprising the DID, a plurality of attributes, and a first plurality of proofs, and (b) a verifiable presentation (VP) data structure comprising the VC data structure and a second proof.

Abstract: Disclosed herein is a power generating apparatus for extracting energy from flowing water. The apparatus comprises a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel which comprises a turbine rotor mounted to a nacelle, and a support structure. The turbine assembly is pivotally moveable between a first position and a second position. When the power generating apparatus is floating on a body of water, in the first position the nacelle is fully submerged below the water surface; and in the second position at least a part of the nacelle projects above the water surface. Movement of the turbine assembly from the first position to the second position is buoyancy assisted, for example by providing the turbine assembly with positive buoyancy or selectively increasing its buoyancy.

Abstract: Apparatus and methods are provided for enabling a sensor device to receive and transmit updates effectively via one or more rules applied to a plurality of event records for transmission by an event management server. In one exemplary embodiment, the event management server manages the plurality of event records (such as records of deletions or updates to a user's profile or goals), via an event suppression application. The event suppression application ensures that event records are not redundantly provided to the sensor device and/or irrelevant records (such as those which no longer contain the most up-to-date information) are not provided to the sensor device. Hence, only the most relevant event records are provided and that those which are not relevant are ignored (not transmitted). In this manner, the sensor device may operate more efficiently to receive only the most relevant transmissions.

Abstract: A method, a false start detection system, and a false start detection sensor for determining whether an athlete has performed a false start in an event. Force data is received representing the force exerted by at least one upper appendage of the athlete on a surface when in a starting position (S701). The force data is processed to determine an athlete start time (S702), and the athlete start time is compared to an event start time to determine whether a false start has occurred (S703).
