Abstract:
This invention provides a system and apparatus that is able to authenticate and prevent illegal manufacturing and unauthorized operation of disposable bioprocess components. This invention utilizes a ferro-electric random access memory chip (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written in sequence into the memory chip, so that the redundant information can remain in the chip when the RFID tag and disposable bioprocess component is gamma-sterilized. Also, this invention includes a method for authenticating the disposable bioprocess component that reduces liability in that a counterfeit poor quality disposable component is not used on the hardware so the user will not file an unjustified complaint.

Abstract:
Sensor devices are disclosed possessing substrates having enhanced resistance to solvents. The sensor device (10) has a sensor region (12) deposited on a substrate (14). In optional embodiments, a protecting layer (16) is applied over the sensor region. The substrates include polycarbonates combined with solvent resistance-imparting monomers that result in a copolycarbonate substrate immune to attack by organic solvents commonly used in sensor deposition and improve the quality of the deposited sensor regions.
Abstract:
The present invention related to devices and methods for using ferrite alignment keys in wireless remote sensor assemblies. In one aspect, the invention provides wireless resonant sensor assemblies comprising a pick-up coil, a ferrite alignment key positioned in and extending from the pick-up coil, and wireless resonant sensor having a receiving element wherein the pick-up coil and the wireless resonant sensor align upon insertion of the ferrite alignment key into the receiving element. The ferrite alignment key may also be part of a resonant sensor such that insertion of a pick-up coil into a receiving element of the alignment key results in a configuration where the alignment key is positioned in and extended from the pick-up coil. Methods of measuring one or more parameters of a monitoring system are also provided. The insertion of the ferrite alignment key aligns the pick-up coil and wireless resonant sensor thereby increasing sensing of the wireless resonant sensor by the pick-up coil.
