Abstract: An electrode for attachment to a patient comprises a flexible planar member, an electrically conductive member embedded in said flexible member and adapted for contact with the patient, a layer of electrically conductive adhesive applied to the conductive member and the flexible planar member on a side of the flexible planar member facing the patient. Through holes extend completely through the electrode and, optionally, may also extend through the layer of adhesive. Alternatively, a permeable electrode having a permeable member which allows a solvent to pass through to the adhesive may be used to eliminate the need for through holes in the electrode. The permeable electrode may also be coated with sodium chloride or potassium chloride and used in conjunction with an applicator containing an alcohol gel which liquefies upon contact with the sodium chloride or potassium chloride.

Abstract: A scraping apparatus or scraper for contacting an adhesive device and skin to which the adhesive device is attached, at an interface between the adhesive device and the skin, to remove the adhesive device from the skin. In one configuration, the scraping apparatus includes a fluid for reducing the adhesion of the adhesive; an element for holding the fluid; and a scraping component. The scraping component is connected to and in fluid communication with the fluid holding element and has at least one first opening distal to the fluid holding element. The scraping apparatus also includes a structure for closing the first opening. In another configuration, the scraping apparatus further includes an element for propelling the fluid to the scraping component. The propelling element may be a compressed gas.

Abstract: Optical apparatus which compares the transmittance of radiation through a coated product with the transmittance of radiation through only the base material of the coated product to measure the coating weight of the coating on the coated product. A dichroic filter or similar device is included to minimize or even eliminate radiation losses, due to reflections from the coated product, which affect the accuracy of the apparatus. The apparatus can be modified to measure selected characteristics of the base material instead of the coating.
