A method of processing a lens is disclosed. A lens blank and a lens block are each provided with a structured surface having a plurality of tapered elements. The lens blank is releasably attached to the lens block by pressing the structured surface of the lens blank against the structured surface of the lens block, followed by subjecting the mounted lens blank to lens processing operations.

A biomedical electrode is disclosed which generally comprises an insulator construction and a conductor member. The conductor member is preferably a thin flat, flexible member having a pad portion and a tab portion. The insulator construction is arranged such that the conductor member pad portion is positioned on one side of the insulator construction and the tab portion is generally positioned on an opposite side. Three general embodiments are disclosed which achieve this: a first comprising two overlapping sections of insulator material, with the tab portion of the conductor member extending outwardly from therebetween; a second in which two sections of insulator construction material are oriented in a substantially coplanar relationship to define a seam therebetween, through which a portion of the conductor member extends; and, a third in which the insulator construction includes a single sheet of material having a slot therein, through which a portion of the conductor member extends. For any of those three embodiments, a substantially flat arrangement results, with advantages associated therewith. Preferred arrangements having a field of conductive adhesive, associated with the pad portion of the conductor member, completely surrounded by a border of insulator construction and skin adhesive, are described.

Films coated with a primer and an adhered layer of metal, metal oxide, metal salt, semiconductor material are shown. The primer is comprised of binder and powder particles and is coated to a dry thickness between 1 micron and 100 microns. The powder particles have a median effective spherical diameter between 0.5 microns and 100 microns.

Coated films

A biomedical electrode comprised of an electrical terminal member, an ionically conductive layer, a retainer sheet, a medical tape, first and second release liners, and a protective sheet is provided. The base of the electrical terminal member is disposed between the retainer sheet and the ionically conductive layer so that the retainer sheet prevents dislodging of the terminal upon connection and disconnection of a lead-wire. Also disclosed is an economical high speed method of manufacturing electrodes.
