Abstract: The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

Abstract: A photographic still camera for receiving an elongated filmstrip having a cross-film curvature and having a substantially transparent magnetic layer deposited on the film surface and for recording or reproducing information on or from the magnetic layer in relation to the exposure of image frames of the filmstrip. The filmstrip is transported from supply to takeup chambers between film rails and a backing plate past a camera image frame exposure aperture with the magnetic layer facing the backing plate and having a concave cross-film curvature across the image frame area. A magnetic recording multi-head array formed of a plurality of recording heads mounted on flexure elements of a flexure support is positioned to extend across and contact the magnetic layer in the image frame area at the side of the exposure aperture.

Abstract: A photographic still camera for receiving an elongated filmstrip having a cross-film curvature and having a substantially transparent magnetic layer deposited on the film surface and recording or reproducing information on or from the magnetic layer in the image frame areas of the filmstrip. The filmstrip is transported from supply to takeup chambers between film rails and a backing plate past a camera image frame exposure aperture with the magnetic layer facing the backing plate and having a concave cross-film curvature near one side of the exposure aperture. A plurality of inverted gull wing shaped, spring flexure elements are positioned to extend across the magnetic layer at the side of the exposure aperture. Each flexure element has a fixed mounting plate attached to the backing plate coupled through an angled fixed leg to a mounting platform which in turn is coupled through a further angled leg back to a further plate such that the mounting plate is suspended toward the filmstrip magnetic layer.

Abstract: A magnetic assembly for detection and authentication of magnetic documents. The magnetic assembly includes a permanent magnet (PM), first and second magnetically soft high permeability pole pieces shaped to form a tapered, variable gap size magnetic circuit with the permanent magnet. The PM is located at a first gap between the first and second pole pieces. A magnetoresistive (MR) sensing element is located at or near the center of a second gap between said first and second pole pieces. The second gap and MR sensing element are proximate a magnetic document to be sensed.

Abstract: Magnetic recording and/or reproducing heads particularly for use for recording and reading information on a magnetics-on-film (MOF) layer in the image area of photographic filmstrips exhibiting a cross-film curvature in cameras or other filmstrip handling apparatus. A magnetic record/reproduce multi-head array is formed of a plurality of magnetic head elements mounted to extend across the width of the filmstrip and across the filmstrip image frame area, each head element contacting the magnetic layer at a predetermined cross-film position in a film transport path. The surfaces of the head elements aligned to contact the filmstrip magnetic layer are burnished or lapped by an abrasive tape lapping of the head as a final contouring operation on the head to remove all edges that can scrape or scratch the magnetic surface of the filmstrip. An elongated, compliant backing support, e.g.

Abstract: A photographic still camera for receiving an elongated filmstrip having a cross-curvature in the cross film direction across said filmstrip and having a substantially transparent magnetic layer deposited on the film surface and for recording or reproducing information on or from the magnetic layer in the image area in and relation to the exposure of image frames of the filmstrip. A magnetic head is formed of a plurality of frustums including inner frustums supporting a plurality of active head gaps in an interior region and at least one further outer frustum on each side of the inner frustums in the cross film direction.

Abstract: A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye to a transfer temperature for transfer to a receiver to form images of selective pixel size thereon. The head has a row of electrodes with end faces and an electrically non-conductive substrate with an end face, the end faces lying in a contact plane for contact with the ribbon. A groove in the substrate end face separates such end face from the electrode end faces. The width of the groove is sufficient to inhibit heat transfer at the groove from the ribbon to the substrate for controlling the dye amount heated to transfer temperature adjacent the groove during the relative movement and in turn the image pixel size.
