Abstract: A method to measure compliance with a pharmaceutical regimen, by the steps of: (a) ingesting a dose of a medication (10) into the gastrointestinal tract of a person, the dose of medication (10) comprising a drug formulation (13) and a permanent magnet (14); (b) as a result of the ingestion of step (a), detecting passage of the permanent magnet (14) past at least two magnetic field sensors (20) positioned apart from each other and adjacent to the gastrointestinal tract; and (c) measuring compliance with the pharmaceutical regimen by way of the detection of step (b).

Abstract: A device useful for oral drug delivery device consisting of: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet, a ferromagnetic object, a ferrite object and an electromagnetic shielding object positioned within, over or adjacent the antenna of the RFID tag to alter the antenna characteristics of the RFID tag so that if the RFID tag is interrogated before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tag is sufficiently altered or attenuated to determine that the capsule, tablet or pill has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the capsule, tablet or pill has dispersed in the gastrointestinal system, the object separates from the RFID tag so that the response of the RFID tag is sufficiently detectable to determine that t

Abstract: Disclosed is a process for making a two or more component foam composite obtained by adhesion of a polyurethane foam onto a substrate comprising the steps of frothing an aqueous polyurethane formulation; applying the froth to a substrate and drying the froth into a foam wherein the foam has a dry density of 35 kg/m3 to 160 kg/m3 (2.2-10 lbs/cft). The process allows the production of foam backed textiles without the need for a flame lamination step or the need for an adhesive layer between the textile and the foam layer and is optionally optimized for superior handling properties for covering polyurethane molded foam cushions.
