Abstract:
A method of manufacturing a micro-electromechanical fluid ejecting device includes the step of forming a plurality of nozzle chambers on a wafer substrate. Sacrificial layers are deposited on the wafer substrate. A plurality of fluid ejecting mechanisms is formed on the sacrificial layers to be operatively positioned with respect to the nozzle chambers. The sacrificial layers are etched to free the fluid ejecting mechanisms. The fluid ejecting mechanisms are formed so that they are capable of ejecting fluid through both of a pair of fluid ejection ports defined in a roof of each nozzle chamber on one cycle of operation of the fluid ejecting mechanism.
Abstract:
This invention concerns a consumable authentication protocol for validating the existence of an untrusted authentication chip, as well as ensuring that the Authentication Chip lasts only as long as the consumable. In a further aspect it concerns a consumable authentication system for the protocol. In this invention we are concerned not only with validating that an authentication chip is present, but writes and reads of the authentication chip's memory space must be authenticated as well. A random number and an encrypted version of it are produced in a trusted authentication chip and passed to an untrusted authentication chip. The untrusted chip encrypts the random number to determine whether it gets the same result as the trusted chip. If so then it re-encrypts the random number together with a data message using a second key and sends it back with the data message. The trusted chip then encrypts the data message and random number with the second key for comparison.
