  • Publication number: 20230276709
    Abstract: Material properties are manipulated using rapid pulse application of energy in combination with applied electric or magnetic fields. When sintering, annealing or crystallizing a target film, the pulse repetition cycle can be constrained to ensure material temperature rises above and falls below the Curie temperature before the next energy pulse. This process results in enhanced material properties as compared to traditional techniques having a single, slow temperature excursion and subsequent application of the applied external field.

  • Publication number: 20220218286
    Abstract: Apparatus, system and method for medical analysis of a seated individual, includes determining the aortic valve opening; the PTT; and calculating the PWV. Determining the aortic valve opening includes collecting BCG data while sitting on a seat and determining the timing of the aortic valve opening, taking into account posture. Measuring the aortic pulse wave transit time includes collecting BCG data while sitting on a seat capable of measuring changes in apparent weight; determining the timing of the aortic valve opening; detecting the arrival of the pulse wave at the end point; and measuring the relative timings of the two events. Calculating the PWV includes determining a length of the arterial segment through which a pulse wave is to be measured between a start point and an end point; and dividing the determined length of the arterial segment by the PTT.

  • Patent number: 11254156
    Abstract: An approach to printing a nickel precursor ink on a wide range of substrates for electronics and magnetic applications is disclosed. The nickel ink reduces to elemental nickel following heating. The ink was printed using an ultrasonic aerosol printing technique. By sintering the nickel precursor ink in the presence of a homogeneous magnetic field, the reduced nickel complex formed continuously aligned nickel nanofibers axially aligned with the direction of the magnetic field. The fabrication of aligned interlayered nanofiber films provides opportunities to produce structures with enhanced isotropic electrical and magnetic properties. The resistivity of the film was found to be as low as 0.56 m?·cm, and the saturation magnetization was measured to be 30 emu/g, which is comparable to bulk Ni. Magnetic anisotropy was induced with an easy axis along the direction of the applied magnetic field with soft magnetic properties.

  • Publication number: 20210219924
    Abstract: An integrated bioinstrumentation system, combining an accurate and robust quasi 1D computational model with experimental peripheral measurements, is designed to extract information on other quantities of interest, for which the direct measurements are not feasible. The system is able to quantify and visualize the distributions of a cardiac output (CO), aortic blood pressure (BP), flow, velocity, and aortic arterial compliance, based on a peripheral analysis of a pulse transit time (PTT) measured at the available peripheral sites. A preliminary calibration stage extracts the arterial properties from simultaneous measurements of a pulse transit time, and an upper arm blood pressure. Obtained transfer functions, linking noninvasive peripheral measurements to the aortic pressure, cardiac output, aortic compliance and others serve to quantify the indicators of cardiac morbidity and mortality.
