Abstract: In general, techniques are described for filter media monitoring within a filtration system. The filter media monitoring techniques described herein include, for example, direct contact with the filter media, e.g., a sensor may be located inside a boundary defined by a surface of the filter media, or indirect contact with the filter media, e.g., a sensor may be located outside the boundary defined by the surface of the filter media such that the sensor does not make direct physical contact with the filter media being monitored.

Abstract: A fluid treatment cartridge includes a housing having a fluid inlet and a fluid outlet with a treatment media contained within the housing. The fluid treatment cartridge includes a detection member comprising at least one closed electrically conductive loop having at least two spatially separate sections. Each of the sections generates a magnetic response when at least one section is electromagnetically excited. The magnetic response of each section is predetermined by the physical shape of the section and comprises at least one of a predetermined magnetic phase response and a predetermined magnetic amplitude response. The predetermined magnetic response of at least one other section of the closed electrically conductive loop corresponds to at least a one digit code.

Abstract: A touch panel includes a touch sensor having a dielectric core layer disposed between first and second piezoelectric layers. Each piezoelectric layer comprises a poled piezoelectric polymer. The touch sensor further includes at least a first set of individually addressable electrodes disposed over the first piezoelectric layer and at least one second electrode disposed over the second piezoelectric layer. Circuitry is coupled to the first set of electrodes and the second electrode. The circuitry is configured to detect a change in an electrical signal of at least one electrode of the first set of electrodes referenced to the second electrode in response to a touch applied to the touch surface of the touch sensor.

Abstract: Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

Abstract: Systems and methods for authenticating material samples are provided. Characteristic features are measured for a batch of material samples that comprise substantially the same composition and are produced by substantially the same process. The measured characteristic features have respective variability that is analyzed to extract statistical parameters. In some cases, reference ranges are determined based on the extracted statistical parameters for the batch of material samples. The corresponding statistical parameters of a test material sample are compared to the reference ranges to verify whether the test material sample is authentic.
