Abstract: The present disclosure provides tracking systems and methods. One such method comprises generating a continuous wave signal over a frequency range; applying the continuous wave signal to a reading coil element that is electromagnetically coupled to a sensor array, wherein the sensor array comprises a plurality of sensing resonators tuned at different resonance frequencies, where an output frequency response of the sensor array varies as a function of a location of a target object or a shape of the target object within a coverage area of the sensor array; acquiring frequency spectrum data showing changes in the output frequency response of the sensor array from the reading coil element; and predicting, by a control unit device using machine learning, a location of the target object within the coverage area or a behavior of the target object based on the acquired frequency spectrum data. Other methods and systems are also provided.

Abstract: A power surface or chamber having nearly constant electromagnetic field distribution in 3D comprising at least one primary coil and one primary resonance array made of several coils connected in parallel for generating the electromagnetic field distribution; a single power driver circuit for activating the coils; and a secondary coil and an optional secondary resonance coil to recover the generated electromagnetic field and power up an electric device.

Abstract: A homecage system for facilitating an experiment using an animal includes a cage unit configured to hold the animal therein. A misalignment insensitive transmitting resonant wireless power transfer unit encompasses the cage unit. The transmitting resonant wireless power transfer unit is configured to be driven by an external power signal so as to generate a radio frequency wireless power transfer signal. A headstage unit is configured to be physically coupled to the animal and is responsive to the wireless power transfer signal. The headstage unit transmits data wirelessly from a sensor associated with the animal. A control unit is in data communication with the headstage unit and controls the external power signal. A remote unit is in data communication with the control unit. The remote unit transmits control information thereto and that communicates data via a local area network.
