  • Patent number: 9480426
    Abstract: A process is described for testing a biomedical property of an internal tissue of a patient. Optical energy emitted by an external source is transferred through a nail of the patient to an instrument device implanted beneath the nail. A portion of the transferred optical energy is converted to electrical power for driving components of the implanted instrument. Using the electrical power, a characteristic of the internal tissue associated with the measurement of the biomedical property is sensed and an optical signal based on the sensed characteristic is transmitted through the nail to an external data reader.

  • Publication number: 20160266035
    Abstract: MIR spectroscopy systems comprising hierarchical spectral dispersion that enables fine spectral resolution and high sensitivity spectroscopy are disclosed. Hierarchical spectral dispersion is derived by employing at least two diffractive lens arrays, located on either side of a test sample, each receiving input radiation having an input spectral range and distributing the input radiation into a plurality of output signals, each having a fraction of the spectral range of the input radiation. As a result, the signal multiplication factor of the two arrays is multiplied in a manner that mitigates the propagation of wavelength harmonics through the system. In some embodiments, an emitter array comprising a plurality of spectrally selective emitters provides the input MIR radiation to a spectroscopy system. In some embodiments, spectrally selective detectors are used to detect narrow spectral components in the radiation after they have passed through the test sample.

  • Patent number: 9401240
    Abstract: A magnetic apparatus having at least one magnetic shim situated between faces of two permanent magnets. The magnetic shim helps to make the magnetic field that is accessible between the two permanent magnets a more uniform field. The magnetic shim is constructed on a thinned semiconductor wafer, such as silicon, by photolithographically defining locations on the wafer where magnetic material, such as iron or iron-nickel materials, are deposited. The shim can additional have photolihographically defined coil regions, in which conductive material such as copper can be deposited. Current contacts are provided to allow currents to be passed through the coil regions. Protective layers can be deposited to protect the deposited metals from mechanical or environmental damage.

  • Patent number: 9365816
    Abstract: Apparatus and methods for mechanical cell lysis with single cell resolution which requires very low applied pressure. The device can be handheld, simple to operate, requires no external power except for hand-applied pressure via a syringe, and is applicable to all cell types including yeast and bacterial cells. The device is also capable of mechanically lysing a single cell. A single cell is selected from a biological sample of interest. The single cell is lysed by application of mechanical stress in a single cell lysing apparatus having a trap structure for deterministically capturing the cell and a stress raiser that cooperates with a source of mechanical stress so as to apply sufficient force to rupture a cell. The stress raiser can be a properly designed edge of the trap or it can be a lithographically produced structure such as a nanoblade or a nanopillar.

  • Patent number: 9316586
    Abstract: This invention provides a system for performing PCR, and real time PCR in particular, with great speed and specificity. The system employs a heat block containing a liquid composition to rapidly transfer heat to and from reaction vessels. The system makes use of the reflective properties of the liquid metal to reflect signal from the PCR into the vessel and out the top. In this way, the signal can be measured by an optical assembly in real time without removing the vessels from the heat block.
