Abstract: A method for privacy-preserving identity verification includes, at a computing node, receiving, over a computer network, a unique user identifier for a user within an online community, and a community identifier for the online community. An identity profile identifier is computer-generated based at least in part on the unique user identifier, the community identifier, and a nonce identification value. A network-accessible identity profile for the user is computer-generated, the identity profile including one or more verified identity claims for the user, and the identity profile indexed by the identity profile identifier.

Abstract: A computing system comprises a plurality of network computing devices, each maintaining an instance of a blockchain. The blockchain includes an ordered set of blocks, each block including one or more transaction entries and a cryptographic hash of an immediately preceding block. The blockchain further includes new participant introduction logic configured to add a transaction entry to a block of the blockchain. The transaction entry includes a blockchain account and a verifiable unique digital identity including a public cryptographic key.

Abstract: An integrated switching regulator device has a switching mode regulator comprising an input voltage source and a switching circuit coupled to the input voltage source configured to generate a pulsed voltage from the input voltage. A low pass filter is coupled to the switching regulator and is configured to filter the pulsed voltage to provide a regulated voltage to a load. The low pass filter comprises at least two LC stages, wherein the first LC stage comprises an air cored inductor and each subsequent LC stage comprises a non-air cored inductor. The switching circuit comprises two or more switching elements configurable to operate at a switching frequency of several megahertz.

Abstract: A system for credentialing a miner for a blockchain system is provided. The system interacts with a Trusted Witness to obtain a witness statement attesting to the identity of the miner. The witness statement includes a miner public key of the miner and a signed miner public key signed using the corresponding miner private key. The system provides to a notary the witness statement and signed bylaws signed using the miner public key. The system receives from the notary a digital identity signed by the notary that includes an identification of the notary, the witness statement, and the signed bylaws. The miner uses the digital identity when participating in mining for the blockchain system.

Abstract: A switched mode power supply converter comprises a circuit pulse matching circuit configured to negate output voltage disturbance or noise during switching operation of a power conversion. The current pulse matching circuit input is driven by, or from, a power converter switch node of the switched mode power supply converter. The current pulse matching circuit comprises a rate-of-voltage change detection circuit driven by the power converter switch node.

Abstract: A handler for drill rods, a drill rod support thereof, a method of operation for the handler, and a drill rig employing the handler and the drill rod support is provided. The drill rod support includes a socket configured to receive a portion of a length of a drill rod, and a clamping device disposed within the socket and movable between clamping and release positions with respect to the drill rod.

Abstract: A distributed database management system balances the load on query boundaries and to achieve a more evenly balanced load. The system includes two or more query processors with a common data source. A database client manages a transaction including two or more queries. A transaction analyzer checks if a transaction can be processed by more than one query processor. A query processor optimizer locates the optimum query processor for each query in the transaction based on workload of each query processor, while a workload balancer directs each query to the optimum query processor if the transaction can be processed by more than one query processor. This approach is particularly well suited to a clustered database environment that includes query processor nodes that work off a shared disk to provide database access to clients that connect to the node.

Abstract: A system comprising a processor and a compression module coupled to the processor. The compression module is adapted to perform motion estimation on video data using an algorithm, the motion estimation performed at a rate. If the processor determines a difference between the rate and a target rate, the processor adjusts a precision level of the algorithm such that the difference is decreased.
