A printhead integrated circuit that has an array of ink chambers, each having a nozzle and an actuator for ejecting ink through the nozzle. The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. The management information includes service level information for a transparent connection, for example, a Digital Subscriber Line connection carrying encapsulated frame relay packets between two networks, for example a wide area network and a local area network. The deployment tool may make use of the metadata when generating deployment classes for the undeployed enterprise java bean. In another embodiment, the wet etch includes a base that adjusts the pH of the etch to selectively remove certain extrusions relative to other substances in the wordline. The ultraviolet irradiation unit is supported by the X-axis driving mechanism on a rear side.
