摘要:
A remote sensing device includes a sensor and reference circuit. A resonant circuit of the sensor has a resonant characteristic modifiable by exposure to an external condition. The sensor is configured to produce a sensor signal associated with the modifiable resonant characteristic. A reference circuit of the remote sensing device is configured to produce a reference signal suitable for use in conjunction with the sensor signal. The reference signal is used to account for variations of the sensor signal due to variations in the inductive coupling between the remote sensing device and a reader designed to detect the reference signal and the sensor signal.
摘要:
Patterned articles can be prepared by applying a release polymer to a substrate in a desired pattern, applying a substrate-adherent polymer over the pattern and substrate, and mechanically removing the substrate-adherent polymer from the pattern without requiring solvent. Suitable mechanical removal methods include applying adhesive tape to the substrate adherent polymer and peeling the tape and substrate-adherent polymer away from the pattern, and abrading the substrate-adherent polymer from the pattern using impact media.

摘要:
A patterned roll apparatus for casting a patterned surface onto an opaque web is disclosed. The patterned roll comprises a curing energy transparent cylinder (102) having an outer surface, the curing energy transparent cylinder (102) permitting at least 10 percent of curing light incident upon the cylinder to pass through the cylinder; a tie layer (104) disposed on the outer surface of the curing energy transparent cylinder (102); and a plurality of curing energy opaque features (106,108) disposed on the tie layer (104) to form a pattern, the curing energy opaque features blocking at least 95 percent of curing light incident upon the curing energy opaque features.
摘要:
An apparatus and a method for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll (18) , a second pattered roll (20) , and a means for rotating the first and second patterned rolls (18,20) such that their patterns are transferred to opposite sides of the web (12) while it is in continuous motion. During this process, their patterns are the first and second patterned rolls (18, 20) comprise a plurality of regions opaque to the curing energy maintained in continuous registration to within at least 100 micrometers.
