摘要:
There is provided a hook fastener capable of engaging a suitable loop fabric comprising a base, where at least one surface has a multiplicity of engaging projections having a top surface and an attached end that are arranged in a region to form one or more shapes.A method for forming the above fastener comprises providing a polymer particles and a base. Dispersing onto a contact release surface a multiplicity of polymers particles in at least one discrete area forming a predetermined shape and forming preform projections. The front surface of the base is fixed to the terminal ends of at least some of the preform projections then removed from the contact release surface in the form of the predetermined shape. The alternatively the preform projections can be provided uniformly on the contact release surface and selectively transferred to the base in the predetermined shape by masks or selective adhesion or the like.In a preferred method polymer particles are dispersed onto a contact release surface using electrostatic attraction to impact the particles onto the contact release surface.

Negative-acting flexographic printing plates display enhanced performance when backside irradiated with ionizing radiation instead of longer wavelength ultraviolet radiation. A better defined floor and more readily controlled floor is produced on the final printing plate.
摘要:
A wetness sensor includes a substrate that carries a tuned RF circuit. The circuit includes a conductive pattern applied to the substrate, a capacitor, and a jumper all disposed on a same side of the substrate. The conductive pattern includes an inductive coil, and an inner and outer terminus. The jumper electrically couples the inner terminus to the outer terminus. The jumper also includes a frangible link which, when contacted by a target fluid, produces a drastic change in the operation of the RF circuit. The drastic change can be interpreted by a remote reader as a “wet” condition. Contact of the frangible link by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or more, and/or may cause the frangible link to disintegrate to produce an open circuit, and/or may substantially render the RF circuit inoperative.
摘要:
A wetness sensor includes a self-supporting substrate and an electrically conductive trace carried by the substrate. The trace is patterned to provide at least a portion of a tuned RF circuit, which may be disposed on only one side of the substrate and characterized by an impedance or resistance. The trace is not self-supporting. The substrate is adapted to dissolve, swell, or otherwise degrade when contacted by a target fluid. Such degradation produces a drastic change in the operation of the RF circuit, which can be interpreted by a remote reader as a “wet” condition. Contact of the substrate by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or 1000, and/or may cause the trace to disintegrate so as to provide the RF circuit with an open circuit, and/or may substantially render the RF circuit inoperative.

摘要:
A method for forming a fasteners is disclosed comprising providing a multiplicity of suitable polymer particles, providing a base with a front surface, and dispersing the particles onto at least one discrete area of the contact release surface, forming a predetermined shape. The dispersed particles are provided in a semiliquid state of a suitable viscosity, at least some of the particles in the discrete areas being in contact with the contact release surface for a time sufficient to transform into preform projections. The method further comprises conducting and fixing the front surface of the base with the terminal ends of at least some of the preform projections and removing the base from the contact release surface to separate the preform projections fixed thereto and form engaging projections projecting from the front surface of the base in the form of a predetermined shape.
