Abstract: An orthodontic elastic band which is dyed with a semi-persistent food-based dye such that the distinction between unused and used elastic bands is evident upon inspection is used in conjunction with a compartmented container, such as a weekly pill box. The compartmented container is used to store used orthodontic elastic bands as they are removed and replaced, before and after meals, respectively, throughout the day. Verification of the rigor with which a predefined orthodontic regimen involving replaceable elastic bands is determined based upon the inspection and count of the number of used elastic bands which have been stored in the compartment associated with each day. Missing, used elastic bands are indicative in a lapse in the prescribed elastic band regimen.

Abstract: The invention, which is an embodiment of what the inventor calls, “Active behavior Fingerprint Authentication” is one which employs a sequential reading of fingerprints of various fingers, in a way that may or may not be time constrained, as a means to improve authentication security. Authentication security is strengthened based upon the reduced likelihood that a potential intruder would 1.) Know what the correct sequence of fingerprints were associated with the control authentication template; 2.) Know the correct timing characteristics associated with successive fingerprint readings; 3.) Be able to successfully “hack” the authentication server in order to gain access to minutia or image information, and finger sequence information, and timing information, which would be required in order to fully compromise the authentication system. The technique embodied by the invention represents an overlay of a known, ordered sequence, which may or may not be timed, over the fingerprint authentication process itself.

Abstract: The invention, which is an embodiment of what the inventor calls, “Active Behavior Enhanced Iris Recognition Authentication”, employs a sequential iris imaging process where the authenticating party directs his or her gaze in specific directions, or closes their eyes for each image, so that an “eye state order” can be used to improve authentication security. Authentication security is strengthened based upon the reduced likelihood that a potential intruder would 1.) know what the correct sequence of eye states (i.e. up, down, left, right, camera view and closed) were associated with the control authentication template; 2.) be able to successfully “hack” the authentication server in order to gain access to the iris image information and also the eye state order information which would be required in order to fully compromise the authentication system. The technique embodied by the invention represents an overlay of a known, ordered sequence, over the iris recognition authentication process itself.

Abstract: A time domain password protection system comprises a password of various letters that must be entered at specific clock times to have the password recognized as valid.
