    摘要: A field portable mass spectrometer system comprising a sample collector and a sample transporter. The sample transporter interfaces with the sample collector to receive sample deposits thereon. The system further comprises a time of flight (TOF) mass spectrometer. The time of flight mass spectrometer has a sealable opening that receives the sample transported via the sample transporter in an extraction region of the mass spectrometer. The system further comprises a control unit that processes a time series output by the mass spectrometer for a received sample and identifies one or more agents contained in the sample.

    摘要: An apparatus and method for non-invasive sensing of bone healing is disclosed. The apparatus and method uses an electromagnetic field to measure impedance changes at and about the bone fracture site during the healing process. The impedance change at the fracture site is a direct indication of the mechanical strength of the fracture site. A multi-coil sensor array is taught, which may be sutured to the patient's skin or mounted onto a plug that is inserted through a window in the cast.

    摘要: An apparatus and method for non-invasively sensing physiological changes in the brain is disclosed. The apparatus and method uses an electromagnetic field to measure localized impedance changes in brain matter and fluid. Various spatial and temporal techniques are used to localize impedance changes in the brain. The apparatus and method has particular application in locating and providing time-trend measurements of the process of brain edema or the process of hydrocephalus.

    摘要: A noninvasive glucose monitoring device includes a drive-and-sense coil and an electronic oscillator with multiple circuits electrically connected to the coil. The drive-and-sense coil may be embedded in either a finger clip or a finger push button. The device measures bioimpedance with a magnetic field coil outside a user's finger. The coil measures blood and glucose electrical conductivity without penetrating the finger. No blood extraction is required. A noninvasive method of measuring glucose in-vivo includes placing the drive-and-sense coil next to a subject's finger and inducing magnetic fields in blood in the subject's finger. A change in mutual impedance between the drive-and-sense coil and the blood is measured at predetermined frequencies and glucose content is calculated from the change in mutual impedance according to a predetermined correlation for each frequency.
