Abstract: The present disclosure generally relates to an electronic circuit and method of operating thereof to back up write cache data on DDR memory in data storage devices during an emergency power off (EPO). The method involves using a power management integrated circuit (PMIC), a combo driver and one MOSFET for regulator output. The method involves detecting a voltage value that is below a predetermined threshold value, retracting a write head away from a hard disk drive (HDD), backing up data, and then resetting the HDD after the backup is complete. The backing up and retraction may occur in parallel or in sequence. The method utilizes the spindle back-electromotive force (BEMF) power to have sufficient power to make the backup. If the power from the spindle BEMF is too low, then the retraction is suspended and a high impedance is present to lighten the load until the BEMF recovers before the power on reset. As such, the back-up data is not reset and volatized by a lack of power.

Abstract: Methods, systems, and devices for leaving evidence of a contract on a blockchain with a simple method while having agreements made among the involved parties, maintaining the mode of one electronic signature per transaction, and maintaining credibility. Transactions of an issuing-party terminal, an agreeing-party terminal, and an agreeing-party terminal involved in contract agreement are linked as a chain, and the agreeing-party terminal at the end generates a transaction directed to the issuing-party terminal who has issued the contract. Each of these terminals previously generates a key pair for encryption of the contract and transmits the encryption key to a terminal which is its transaction sender. Then, this sender terminal encrypts a contract to be included in a transaction of the user of the sender terminal using the encryption key of the receiver of the transaction.
