Abstract: A cleaning article includes a cleaning article sheet comprising a fabric substrate, wherein the fabric substrate includes pores therein, and wherein the fabric substrate has a background moisture percentage by weight, and liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at moisture percentage by weight that is 5 to 150 percentage points higher than the background moisture percentage. The nonwoven substrate can include pores formed between and/or within the fibers and can have a background moisture percentage by weight. The substrate can include a treatment to increase the dielectric constant from the dielectric constant of the substrate without the treatment. The moisture of the article can be configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article with only background moisture.

Abstract: An absorbent article facilitating sensing the presence of a body exudate in the absorbent article includes an absorbent member; a sensor coil disposed on or in the article; and an electrical double-layer capacitor disposed on or in the article and in electrical communication with the sensor coil, wherein the capacitor is in fluid communication with the absorbent member. An absorbent article system also includes a detector circuit including an exciter coil configured for electromagnetic communication with the sensor coil, and sensor electronics configured to indicate the presence of a body exudate based on changes in the electromagnetic communication between the exciter coil and the sensor coil.

Abstract: A wetness monitoring system is provided for an absorbent article, the wetness monitoring system including a signaling device including an alarm to indicate that the absorbent article has reached an insult limit. The signaling device operates with a sensor array which is disposed on the outermost surface of the absorbent article outer cover. The signaling device includes a detection circuit which measures changes in inductance or capacitance. The wetness monitoring system does not make direct contact with the absorbent structure located within an outer cover of the absorbent article.

Abstract: A gyroscope comprises a piezoelectric substrate having a surface. Disposed on the surface are a resonator transducer, a pair of reflectors, a structure such as a metallic dot, and a sensor transducer. The resonator transducer creates a first surface acoustic wave on the surface. The pair of reflectors reflects the first surface acoustic wave to form a standing wave within a region of the surface between the pair of reflectors. The structure is disposed on the surface within the region, wherein a Coriolis force acting upon the structure creates a second surface acoustic wave. The sensor senses the second surface acoustic wave and provides an output indicative thereof.

Abstract: A class of antennas that comprise an electrically conductive fractal pattern disposed on a dielectric substrate and are capable of construction in a size measured in centimeters as compared to previous antennas of the same class that measured in meters. One antenna style has a ground plane that is perpendicular to the substrate and another style has a ground plane that is parallel to the substrate. The substrate has a dielectric constant of in the range of about 10 to 600 or more and may be a ferroelectric, such as barium strontium titanate. A bias voltage applied across the substrate can tune the antenna for operation in a particular frequency range. The antenna can be made especially wideband by placing an absorbing material behind the substrate. The fractal pattern may be any fractal pattern, such as Hilbert curve, Koch curve, Sierpinski gasket and Sierpinski carpet.
