An environmental tracking system provides facilities for modeling the processes of an organization that have an impact on the environment. The environmental tracking system allows each process to be modeled by its input substances and its resulting output substances. The environmental tracking system allows links to be established between the processes, such as indicating a source process and a destination process for a substance. Each process performs a conversion of input substances to output substances in accordance with conversion parameters specified for the process. Once the model of the processes of an organization is established, the environmental tracking system can track the flow of substances through the organization based on the model.

Measurement Of Device Materials Using Non-Faradaic Electrochemical Impedance Spectroscopy
- Northridge CA, US David Probst - Chandler AZ, US Mohsen Askarinya - Chandler AZ, US Akhil Srinivasan - Pacific Palisades CA, US Melissa Tsang - Sherman Oaks CA, US Michael E. Miller - Culver City CA, US Parisa Kamgar - Los Angeles CA, US
The invention includes method and materials designed to measure the material properties (e.g. thickness) of layers of material in a sensor using non-Faradaic EIS (Electrochemical Impedance Spectroscopy) methods. The methods are non-destructive, very sensitive and rapid. Typically in these methods, an AC voltage is applied to the desired material layer while the output current and therefore impedance is measured. This voltage can be applied in multiple frequencies in sweep mode in order to detect both the material and, for example, the thickness of the target material. In this way, EIS allows the characterization of properties of various layers of material disposed in devices such as electrochemical glucose sensors.
