Abstract: A reagent test paddle includes a contamination detection medium, a reference color bar, at least one chemical test medium, and a unique identifier. The contamination detection medium includes a reagent that changes color in the presence or when exposed to a hostile or inhospitable environment. Each chemical test medium includes a regent that is responsive to a respective analyte in a biological sample. The reference color bar includes reference color samples of different colors. The unique identifier, like a serial number, identifies the particular paddle and its chemical test medium so it can be uniquely and anonymously associated with a user.

Abstract: In accordance with one embodiment, a method for locally verifying the identification of a user with an electronic device is disclosed. The method includes regenerating a neuro-mechanical fingerprint (NFP) in response to a micro-motion signal sensed at a body part. In response to a plurality of authorized user calibration parameters, a match percentage of the neuro-mechanical fingerprint is determined. The match percentage is determined without the use of a calibration NFP that was previously used to generate the user calibration parameters. Access to the electronic device and its software applications is then controlled by the match percentage. If the match percentage is greater than or equal to an access match level, access to the electronic device is granted. If the match percentage is less than the access match level, access is denied. Subsequent access requires further regeneration of the NFP and a determination of its match percentage in response.
