Abstract:
An apparatus, system and method of detecting contaminants, such as melamine, in at least one ingestible item. The apparatus, system and method may include a disposable notched probe having therein at least one send and one receive fiber optic, or electrical, or heat source, and a reactant associated with said disposable notched probe, wherein a reaction of the reactant with at least a portion of the ingestible item indicates, to the consumer user, a presence of a contaminant.
Abstract:
A system and method for verifying that a document is included in a document management system is disclosed. This system and method includes radio frequency scanning at least a portion of the document, generating document data dependently upon the radio frequency scanning, comparing the generated document data to stored document data, the stored document data generated dependently upon a prior radio frequency scanning of at least a portion of the document, and outputting an indication of the document being included in the document management system as determined by the comparing.
Abstract:
A label for tracking and tracing baggage in a baggage handling system is disclosed. The label includes resonators doped into the label. The resonators providing the label with a unique signature and are capable of being read from approximately 2 meters. A baggage handling system incorporating a resonator based label system is also disclosed. The system includes at least one piece of baggage, a label for tracking and tracing baggage in the baggage handling system, at least one reader for reading the label in order to properly direct the attached at least one piece of baggage, and at least one baggage mover suitable for moving the at least one piece of baggage within the baggage handling system. The label includes resonators doped into the label that provide the label with a unique signature, the label being attached to and referenced with said at least one piece of baggage.
Abstract:
A radio frequency automatic identification system detects targets which include solid resonators resonating at several frequencies, attributing information to the frequencies at which the target resonates. Preferred resonators are quartz crystals, which may be made by a process of heating quartz to soften it and cutting crystals to approximate size and resonant frequency. Resonators produced by such a process are measured to determine their actual resonant frequency, and preferably the crystals are sorted into predetermined frequency windows in accordance with their measured resonant frequency. A set of resonators having frequencies corresponding to predetermined data is selected from the sorted groups of resonators and incorporated into a target. The preferred target is an ink-like material having a plurality of resonators disposed in a matrix which is radio frequency transparent at the frequency of interest. Targets are preferably detected by repetitively sweeping the frequency of the interrogating signal through a range which includes the information-bearing range of the system.
