An electrical assembly including a plurality of electrical modules, each of the plurality of electrical modules being sequentially electrically connected to at least one other of the plurality of electrical modules. The protocols present a range of levels of error control and sequence order control. A second embodiment of the invention includes a self laminating wristband similar in construction to other embodiments and comprised of a layer of face stock and a laminate, with the laminating portion having its overlapping half adjoined at the end of the first lamination portion instead of at its side. The plate is disposed adjacent to an end portion of the recording medium and in an arbitrary position between a surface lying substantially on the same plane as the surface of the recording medium and the ink discharge surface of the ink jet head. A portable computer can be coupled to the docking connector so that the computer extends substantially parallel to the base. The applicator and sheet material may be provided together in a kit.
