Abstract: The following relates generally to creating a backup of data and/or settings of a smart device. In some embodiments, one or more processors receive the data and/or settings of the smart device. The one or more processors may then mint a non-fungible token (NFT) that references a link to a data storage area. The data storage area may store: (i) an identification of the smart device, and/or (ii) the received data and/or settings of the smart device. The following also relates generally to providing a warranty of an item. In some embodiments, one or more processors detect an indication of a sale. The one or more processors may then mint a warranty non-fungible token (NFT) that: (a) is owned by the owner of the item, (b) identifies the item, and (c) identifies warranty information of the item.

Abstract: A method of retrieving a directory listing includes steps of storing a plurality of directory listings, each listing searchable by a plurality of keys, each of the keys comprising a plurality of symbols selected from a subset of an alphabet; receiving a sequence of inputs each designating a plurality of the symbols; identifying a number of the directory listings having at least one of the keys consistent with the sequence of inputs; displaying candidate ones of the directory listing having the at least one of the keys consistent with the sequence of inputs; and selecting one of the candidate directory listings to be contacted.

Abstract: A system for interconnecting a printhead cartridge and a cradle unit for supporting the printhead cartridge is provided. The system has a first printed circuit having print control circuitry of the cradle unit, and a second printed circuit board having connections for connecting the printhead cartridge with a power supply which is remote from the second printhead circuit board and the print control circuitry of the first printed circuit board. The first and second printed circuit boards have complementary connectors which cooperate to provide the connection of the printhead cartridge to the print control circuitry. The complementary connectors being arranged so that the first printed circuit board is able to pivot with respect to the second printed circuit board.
