Abstract: Generating a request for reprocessing of a replaceable supply component may include sending to a non-volatile memory of a replaceable supply component, a request for information about the replaceable supply component. The method may include receiving from the replaceable supply component, the supply component information, wherein the supply component information includes data to be decrypted by an exchange service. The method may further include generating a request blob including the supply component information, and cryptographically signing the request blob for sending to the exchange service for reprocessing of the replaceable supply component.

Abstract: A hybrid magnet motor that utilizes two reciprocating magnet head pistons that are 180 (degrees) out of sync., in which acts against a rotating dual polarity magnet wheel (5) which causes a repulsion for the first 180 (degrees) of rotation, then an attraction for the second 180 (degrees) of rotation, when the magnet head piston reaches about 67.5 (degrees) Before-top-dead-center. A timing disk (15) triggers on the appropriate sensor, in which activates or energizes that particular electromagnetic coil, and causes the magnet head piston in question to rotate past the pistons stall out point, which is when the magnet head piston is at its Top-dead-center, or its magnet head piston is closest to the magnet wheel (5). This is the cylinders closest and strongest point of attraction. As the magnet head piston is caused to rotate further After-top-dead-center to about 22.
