  • Patent number: 10797883
    Abstract: Methods and apparatus for storing trackable actions in a ledger are provided. A computing device acting as a node can receive a notification of a trackable action. The trackable action can relate to a printer-related transaction and/or an entry-or-exit transaction. The node can generate a block hash value using a hash function operating on data that includes at least part of the notification. The node can add a new block to a ledger, the new block including: the block hash value, a reference to a previous-block hash value of a previous block in the ledger, and the data that includes at least part of the notification of the trackable action. The node can receive a query related to the ledger. In response to the query, the node can provide an output that includes information about the trackable action.

  • Publication number: 20170143091
    Abstract: Provided is a method for treating keratinous fibers comprising: applying steam to the keratinous fibers at a rate of less than 5 g/min; and shaping the keratinous fibers at a temperature of greater than 50° C., wherein the application of the steam and the shaping of the keratinous fibers do not occur simultaneously. The method disclosed herein may make it possible for example to obtain rapid shaping of the keratinous fibers while improving their cosmetic properties and the comfort of the user.
