Abstract: A method is disclosed for detecting a target substance comprises sensing one or more physical properties that affect a Nuclear Magnetic Resonance (NMR) frequency of a substance, calculating an output frequency by using the one or more physical properties and an NMR frequency associated with the target substance, generating and sending an electrical signal to a detection module, the electrical signal having the calculated output frequency; receiving an indication of the location of the target substance at the detection module.

Abstract: Systems and methods for gathering and updating inventory data within a database through use of a hand-held technology. The method includes the step of collecting a plurality of parameters of data having a first data structure responsive to a user input via the hand-held technology. The plurality of data parameters are gathered and stored on the hand-held technology during inventory counting or replenishment stocking and, once inventory counting or replenishment stocking is completed, the data is prepared for delivery to the database. As such, the computer-executed method and computer program product further entails manipulating the plurality of parameters of data having the first data structure into a second data structure capable of being transceived by a database management system of the database. Once this occurs, the computer-executed method and associated computer program product requires delivery of the data in the second data structure to the database for updating of the data therein.
