摘要:
The packaged medical article can comprise the medical article and a protective layer capable of inhibiting exposure of the medical article to a color change activator prior to use of the medical article. The medical article comprises a plastic portion and an active color changing specie, wherein the color changing specie is capable of changing color after exposure to a color change activator. The method for producing a medical article can comprise: combining thermoplastic resin with a blocked color changing specie to form a resin mixture and manufacture processing the resin mixture to form a packaged medical article. This manufacturing processing comprises forming the resin mixture into the medical article and packaging the medical article to form a packaged medical article. The color changing specie will not affect the structural integrity of the medical article when it changes color.

An apparatus for monitoring the performance of a distributed system is provided. The distributed system comprises a plurality of cooperating units disposed in a communications network. The apparatus comprises a plurality of diagnostic components wherein each unit of the system comprises at least one of the diagnostic components. Each diagnostic component comprises a sensor, a data reduction module, a transceiver and a data analysis module. The sensors sense unit performance characteristics and represent the characteristics as raw data. The data reduction module receives and processes the raw data produced by the sensors to generate reduced data. The transceiver receives the reduced data from the data reduction module and transmits and receives the reduced data to and from the units using the network. The data analysis module accepts and analyzes the reduced data from the transceiver to produce performance data related to the distributed system.

An authentication system may comprise: a first light source, a second light source, and at least three optically filtered light sensing devices. The first light source can have a first light source spectral distribution and can be capable of providing sufficient excitation to produce a photoluminescent emission from a medium comprising a luminescent tag and a color. The second light source can have a visible multi-wavelength spectral distribution and can be capable of providing sufficient visible multi-wavelength illumination of the medium to generate a second analog response. Each light sensing device can have a different device spectral sensitivity range.

A method for imparting tags to a media article, comprising: modifying predetermined locations on the article to change a surface energy of the predetermined locations, applying the tags to a surface of the article, and retaining the tags in the modified predetermined locations while the tags are removed from unmodified regions.
摘要:
A portable system and method for measuring the concentration of multiple chemical or biological substances where an onsite analysis of such substances is needed. The new and original handheld sensor system uses a disposable optical test element and a spectroscopic detector that measures the test element response to specific analytes through a change in light absorbance, luminescence, and other forms of light-based response. In this way, reflection light intensities indicative of the test element response can be used to measure the concentration of the target analytes. The sensor system is also capable of being interfaced to an information processing unit or computer so that analytical data can be manipulated or stored electronically.
