Abstract: A pathogen detection method. A sample that potentially contains a pathogen is collected. A triangle wave form output is produced. A signal associated with the triangle wave form is transmitted from a voltage-controlled oscillator over a plurality of frequencies. The signal is transmitted through the sample to cause the pathogen in the sample to vibrate at a frequency. The vibrations from the sample are detected. A resonance profile of a pathogen in the sample is calculated based upon the vibrations. A database that includes a resonance profile signature of at least one pathogens is provided. The calculated resonance profile is compared to the resonance profile signature database to determine if the sample includes the pathogen.

Abstract: A method of detecting threats. A threat detection system is provided that includes a controller, a millimeter wave radar with transceiver, a signature database, and a camera. The signature database or machine learning includes time and frequency domain characteristic data for a threat. A signal is emitted by the millimeter wave radar. A return signal is received when the signal bounces off an object. Time and frequency domain characteristic data of the return signal is compared to the signature database, or the machine learned characteristics to determine the threat, anomaly, foreign object, material characteristics, and threat speech recognition.

Abstract: In one embodiment, a power system for a plurality of dispensers comprises an AC transformer to receive a line voltage and generate an output voltage of about 2 volts AC to about 50 volts AC; a plurality of dispensers, each housing at least one electrical component operatively configured to dispense product through a dispensing aperture, each of the dispensers comprising a battery compartment; and a plurality of power converters adapted to be at least partially disposed within the battery compartments such that at least one power converter is associated with each dispenser, the converters disposed in communication with the AC transformer such that the power converters receive the output voltage and provide a DC voltage to one or more electrical components housed within the dispensers.

Abstract: An electronic dispenser for dispensing sheet products includes an infrared proximity sensor operative to detect a presence of a user's hand at a predetermined location near the dispenser and a feed mechanism configured to engage a sheet product roll to cause a quantity of sheet product to be dispensed therethrough. The infrared proximity sensor is configured to have an adjustable sensitivity to vary a detection range of the infrared proximity sensor. The feed mechanism has a motor operative in response to the infrared proximity sensor to engage the feed mechanism.
