摘要:
A method of controlling the spread of volatile substances is provided. The method comprises the steps of: a) impregnating a fragrance component comprising at least one PRM onto a plurality of surfaces of a sorbent to form a volatile substance-controlling composition; and b) disposing the volatile substance-controlling composition into an article wherein the fragrance component is released from the sorbent primarily in the presence of one or more volatile substances when the volatile substances are adsorbed by the sorbent.

A contactless programmable electrostatic Radio Frequency Identification (RFID) reader that also serves as an Electronic Article Surveillance (EAS) reader is described. The RFID/EAS reader contains a detector circuit for detecting the presence of a signal carrier frequency transmitted by the transponder in response to a signal from the reader. The detector circuit has a resonator circuit which is connected to a receiver electrode. The resonator comprises a piezoelectric element with a high quality factor ‘Q’ at the resonant frequency to enhance sensitivity. The alarm carrier signal is rectified and fed to either a peak detector or an envelope detector circuit. A voltage source generates a voltage threshold to allow for operating range adjustment. A comparator compares both voltages and generates an alarm signal if the voltage signal reaches the threshold voltage. The RFID/EAS further having the capability to read the RFID contents. Alternatively, an electrostatic EAS reader (without RFID capability) having a substantially similar detector circuit is also described.
