Abstract: A capacitive imaging glove includes electrodes implemented throughout the capacitive imaging glove and drive-sense circuits (DSCs) such that a DSC receives a reference signal generates a signal based thereon. The DSC provides the signal to a first electrode via a single line and simultaneously senses it. Note the signal is coupled from the first electrode to the second electrode via a gap therebetween. The DSC generates a digital signal representative of the electrical characteristic of the first electrode. Processing module(s), when enabled, is/are configured to execute operational instructions (e.g., stored in and/or retrieved from memory) to generate the reference signal, process the digital signal to determine the electrical characteristic of the first electrode, and process the electrical characteristic of the first electrode to determine a distance between the first electrode and the second electrode, and generate capacitive image data representative of a shape of the capacitive imaging glove.

Abstract: A ferromagnetic resonance (FMR) measurement method is disclosed wherein a magnetic film or stack of layers is patterned into elongated structures having a length along a long axis. A magnetic field (H) is applied in two different orientations with respect to the long axis (in-plane parallel and perpendicular to the long axis) or one orientation may be perpendicular-to-plane. In another embodiment, H is applied parallel to a first set of elongated structures with a long axis in the x-axis direction, and perpendicular to a second set of elongated structures with a long axis in the y-axis direction. From the difference in measured resonance frequency (?fr) (for a fixed magnetic field and sweeping through a range of frequencies) or the difference in measured resonance field (?Hr) (for a fixed microwave frequency and sweeping through a range of magnetic field amplitudes), magnetic saturation Ms is determined using formulas of demagnetizing factors.

Abstract: A diaper wetness detection system includes a diaper, a wetness sensor, an RFID unit, and a transceiver unit. The RFID unit is a battery-less device that receives an interrogation signal transmitted by the transceiver unit. The RFID unit or the transceiver unit are configured to determine if a measurable characteristic, as sensed by the wetness sensor, indicates if the diaper is wet. The measurable characteristic can be a voltage or current indicative of a resistance, capacitance, or impedance at an area sensed by the wetness sensor. The value of the measurable characteristic is different when the diaper is wet versus dry. Comparing the measurable characteristic value to a threshold value or to one or more previously sensed measurable characteristic values enables a determination to be made as to whether or not the diaper is wet. The RFID unit can be detachably coupled to the diaper for simple attachment and removal.
