Abstract: A method includes acquiring, at a node server, blockchain data for a blockchain address on a blockchain network. The blockchain data includes a plurality of transactions for the blockchain address. The method includes generating a local node trust score for the blockchain address based on the blockchain data. The local node trust score indicates a likelihood that the blockchain address is involved in fraudulent activity. The method includes receiving, from a plurality of remote servers, a plurality of additional local trust scores for the blockchain address. The method includes determining a consensus trust score based on the local node trust score and the plurality of additional local trust scores. Additionally, the method includes monitoring a ledger on the blockchain network for a contract trust request that specifies the blockchain address and sending, to the blockchain network, the consensus trust score for the blockchain address specified in the contract trust request.

Abstract: A heat assisted magnetic recording (HAMR) assembly includes a slider, a laser diode and solder connections between the laser diode and the slider. The solder connections mechanically and electrically attach the laser diode to the slider. Each solder connection has a total volume per unit area (i.e., height) of less than or equal to about 15 ?m. The solder connections have a first intermetallic zone adjacent to the laser diode, a second intermetallic zone adjacent to the slider, and a eutectic zone of eutectic material between the first and second intermetallic zones. The eutectic zone occupies greater than or equal to about 35% of the total volume per unit area of the solder connection.

Abstract: A method of powering an obstruction detector. Power is provided to an obstruction detector when a motor is executing a first movement and is suppressed to the obstruction detector when the motor is idle and when the motor is executing a second movement. The first movement moves a movable barrier towards a closed position, and the second movement moves the barrier towards an open position.

Abstract: A cleaning device for cleaning an object includes an inner vessel configured to contain a first liquid and the object. The cleaning device also includes an external vessel configured to contain a second liquid and the inner vessel. The second liquid is acoustically coupled to the first liquid. At least one transducer is acoustically coupled to the external vessel and configured to generate acoustical energy which is transferred to the object through the external vessel, a second liquid, the inner vessel and the first liquid. The first liquid has a dissolved gas concentration of a first gas and the second liquid has a dissolved gas concentration of a second gas.
