  • Publication number: 20170227452
    Abstract: Some aspects of the present disclosure feature a system for sensing a change in environment comprising a MMR sensor and a reader. The MMR sensor is configured to be disposed in the environment. The MMR sensor comprises a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The reader is configured to measure a frequency characteristic of the MMR sensor after the environmental variable changes and the change to the environmental variable is evaluated based on the frequency characteristic.

  • Patent number: 9707502
    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.

  • Publication number: 20160291729
    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.

  • Publication number: 20160076945
    Abstract: A system for monitoring temperature of an electrical conductor (31) enclosed in at least a (semi)conductive layer (13) comprising: a passive inductive unit (20), and a transceiver unit (40) and a control unit (50). The passive inductive unit (20) includes at least one temperature sensitive component and is configured to have a resonance frequency and/or Q value that vary with temperature of the electrical conductor (31). The transceiver unit (40) is configured to be electromagnetically coupled to the passive inductive unit (20) and to send out a signal representing the resonance frequency and/or Q value of the passive inductive unit (20). The transceiver unit (40) is further configured to communicate with the control unit (50) which ascertains the signal representing one or both of the resonance frequency and Q value, and which determines a value of the temperature of the electrical conductor (31) based on the ascertained signal representing one or both of the resonance frequency and Q value.

  • Patent number: 8697562
    Abstract: Metal contact formation for molecular device junctions by surface-diffusion-mediated deposition (SDMD) is described. In an example, a method of fabricating a molecular device junction by surface-diffusion-mediated deposition (SDMD) includes forming a molecular layer above a first region of a substrate. A region of metal atoms is formed above a second region of the substrate proximate to, but separate from, the first region of the substrate. A metal contact is then formed by migrating metal atoms from the region of metal atoms onto the molecular layer.

  • Patent number: 7790796
    Abstract: A spackling compound is provided that is easy to apply smoothly, can be applied in thicker layers than known spackling without cracking upon drying, and can be modified after drying without pitting, flaking, or crumbling, particularly at the edges of the applied spackling patch. The composition includes polyaramid fibers that act as structural strengtheners to provide the dried composition with exceptional strength and resistance to cracking. In a second embodiment, the composition further includes low aspect ratio (about equal to 1) ceramic microparticles that fill voids in the mixture to produce a smoother, more dense composition. Upon drying, the ceramic microparticles produce a very smooth surface that can be sanded without flaking or crumbling. Additionally, the invention provides methods of preparing and using the compositions to produce smooth repair patches with no cracks, are easy to sand without pitting or flaking, and to provide improved structural integrity to the repaired area.

  • Patent number: 7504447
    Abstract: In broadest terms, a wood filler composition of the present invention comprises: from about 11.50 to about 17.50 weight percent water; from about 14.40 to about 21.60 weight percent ceramic microspheres; from about 2.48 to about 3.72 weight percent wood flour; from about 0.32 to about 0.48 weight percent thickener; from about 0.80 to about 1.20 weight percent glass bubbles; from about 12.24 to about 18.36 weight percent acrylic latex emulsion; optionally from about 0.05 to about 0.20 weight percent of an adhesion promoter; and from about 36.06 to about 54.10 weight percent calcium carbonate. The composition preferably has a pH in the range of from about 8.4 to about 8.8. Further the composition preferably has a viscosity of between about 200,000 to 300,000 cps as measured on a BROOKFIELD RV viscometer (helipath on) with a T/E spindle at 20 rpm and 25° C.
