  • Publication number: 20230284730
    Abstract: A shoe can include a sock liner assembly configured to receive a reflectant panel and a midsole assembly configured to receive an optical sensor. The optical sensor can include an optical source configured to emit a beam directed to the reflectant panel and an optical detector configured to detect a portion of the beam reflected by the reflectant panel. The optical sensor can be configured to measure a relative displacement between the sock liner assembly and the midsole assembly based on a change of the detected portion of the beam caused by the relative displacement.

  • Publication number: 20230031122
    Abstract: Certain examples of the disclosure concern an apparatus including a microcarrier configured to receive and support attachment and growth of cells, and a magnetoelastic sensor enclosed by the microcarrier. The magnetoelastic sensor is configured to vibrate in response to an activation magnetic field, and the vibration can produce a return magnetic field having detectable field characteristics associated with the attachment or growth of the cells.

  • Patent number: 10736621
    Abstract: Systems and methods for monitoring a mechanical force applied to a wound site repairing structure are disclosed. In an embodiment, the systems include a wound site repairing structure, a magnetoelastic sensor coupled to the wound site repairing structure, and a detection system. The detection system includes an excitation coil configured to transmit a signal to the magnetoelastic sensor and a detection coil configured to detect a signal indicative of a mechanical force applied to the wound site repairing structure. The detection system also includes a detection unit configured to detect the signal indicative of the mechanical force applied to the wound repairing structure.

  • Patent number: 7912661
    Abstract: Circuitry and program code adapted for carrying out an associated technique for characterizing the response of one or more magnetoelastic sensor elements during exposure to an excitation field generated by an interrogation coil: including: (a) measuring a total sensor signal from the coil with the sensor element positioned within the excitation field within a spacing created by a winding of the coil; and (b) automatically determining: (i) a total measured impedance spectrum from said total sensor signal so measured, and (ii) a plurality of magnitude values representing the real part of a reconstructed impedance spectrum for the sensor element. The reconstructed impedance spectrum for the sensor element, having been calculated by subtracting an impedance generally attributable to the coil during the time an AC excitation signal is provided, from the total measured impedance.

  • Publication number: 20080261261
    Abstract: A system/analyzer-unit and method/platform—using information obtained from at least one, adapted for a plurality of, magnetoelastic sensor elements in contact with one or more samples comprising blood from a patient—for automatically quantifying one or more parameters of the patient's blood. Information obtained from emissions measured from each of the sensor elements is uniquely processed to determine a quantification about the patient's blood, such as, quantifying platelet aggregation to determine platelet contribution toward clot formation; quantifying fibrin network contribution toward clot formation; quantifying platelet-fibrin clot interactions; quantifying kinetics of thrombin clot generation; quantifying platelet-fibrin clot strength; and so on.

  • Patent number: 7319411
    Abstract: A network of remote sensing node assemblies, a first and second of which each has a sensor element, as well as associated technique and program code for transmitting information collected about a liquid environment. The network provides the capability of sensing the liquid to collect a wide variety of types of information/data about the liquid and any surrounding environments, and transmitting from the originating node assembly to a different node within acoustic transmission range, and then transmitting further to a third node assembly where the information may be processed and communicated to a user, or further transmitted by way of suitable medium, preferably as electromagnetic signals, to a host location for processing into a compilation of data. Each of at least two sensing node assemblies has at least one sensor element adapted for operation while immersed within the liquid, a source of power, and a transducer for receiving acoustic waves/signals transmitted from another node assembly.

  • Patent number: 6639402
    Abstract: A temperature sensing apparatus including a sensor element made of a magnetically soft material operatively arranged within a first and second time-varying interrogation magnetic field, the first time-varying magnetic field being generated at a frequency higher than that for the second magnetic field. A receiver, remote from the sensor element, is engaged to measure intensity of electromagnetic emissions from the sensor element to identify a relative maximum amplitude value for each of a plurality of higher-order harmonic frequency amplitudes so measured. A unit then determines a value for temperature (or other parameter of interst) using the relative maximum harmonic amplitude values identified. In other aspects of the invention, the focus is on an apparatus and technique for determining a value for of stress condition of a solid analyte and for determining a value for corrosion, using the relative maximum harmonic amplitude values identified.
