Abstract:
A biomedical sensor system is disclosed that includes a high impedance conductive electrode having an electrode impedance of at least about 20 kΩ/sq-mil, and a dielectric material on a first side of the electrode for receiving a discharge of an electrical signal from the dielectric material responsive to the presence of a time varying signal adjacent a second side of the dielectric material that is opposite the first side.
Abstract:
A multilayer composite comprises a printable facestock with a carrier sheet separably laminated directly to its top surface. The facestock is a dimensionally unstable and/or low flexural stiffness transparent film having a thickness not greater than about 4.0 mils. In subsequent processing, graphics are printed on the bottom surface of the facestock followed by the application of pressure sensitive adhesive and a release liner. The liner is removable, allowing the composite to be adhered to a substrate, with the graphics remaining beneath and protected by the facestock. The carrier sheet is separable from the top surface of the facestock, either before or following removal of the release liner.
Abstract:
A multilayer composite for applying printed graphics to a receptive substrate, comprising: a carrier sheet; a transparent breakcoat having an upper surface releasably bonded to the carrier sheet, and a lower print receptive surface on which graphics are permanently printed; and a layer of pressure sensitive adhesive having an upper surface permanently adhered to the thus printed graphics, and a lower surface releasably adhered to a protective liner. The protective liner is separable from the adhesive without disrupting the bond between the carrier sheet and the breakcoat, and the adhesive, and the adhesive is removably bondable to the substrate during a wet out period, after which the carrier sheet is separable from the breakcoat, allowing the breakcoat/graphics/adhesive residue to remain firmly bonded to the substrate.
Abstract:
A composite is disclosed for use in electro-luminescent devices. The composite includes polymeric material having a first surface energy, and phosphorescent material dispersed within said polymeric material. The phosphorescent material has a second surface energy, said first and second surface energies are each between about 32 dynes/cm and 46 about dynes/cm. The polymeric material has a moisture vapor transmission rate of a at least one gram/100 sq. inches for a 24 hour period at 100 °F for a one mil thick barrier.
Abstract:
A water vapor permeable composite is disclosed for use in electroluminescent devices. The composite includes polymeric material having a first surface energy, a phosphorescent material dispersed within at least a portion of said polymeric material; and an electrically conductive material on at least one side of said polymeric material. The conductive material has a second surface energy, said the first and second surface energies are each between about 32 dynes/cm and 46 about dynes/cm. The polymeric material has a moisture vapor transmission rate of at least one gram/100 sq. inches for a 24 hour period at 100° F. for a one mil thick barrier.
Abstract:
A frangible label which includes a plurality of integrally joined layers deposited successively on a removable carrier film. One or more of the layers are electrically conductive and configured to define an electrical circuit. The label is transferrable from the carrier film onto a receiving surface and is otherwise inseparable from the carrier film without attendant disruption of the circuit. In an alternative embodiment, the label includes an adhesive layer for applying the label to a substrate, such that the plurality of integrally joined layers including the electrical circuit are transferrable to the receiving surface and are otherwise inseparable from the carrier film without destruction of the electrical circuit.
Abstract:
An optical device (10) receives incident light (28) having a minimum wavelength, and produces resultant light containing an optical image (32). The device (10) includes a first material (20) having a first index of refraction and a surface (18) embossed with an optical interference pattern (16) and a second material (22) having a second index of refraction deposited onto the embossed surface (18) of the first material (20). The depth of deposition is at least equal to three quarters of the minimum wavelength component of the incident light within the second material.
