  • Method to determine state of a cell exchanging metabolites with a fluid medium by analyzing the metabolites in the fluid medium
    Patent number: 8486690
    Abstract: The present invention relates to a method for determining the ideal time for and outcome of reproductive health procedures including in vitro fertilization by establishing a correlation between the successful outcome of said procedure and the spectra of a body fluid obtained using a chosen analytical modality for a population of patients, acquiring for a patient a spectrum of the body fluid of the patient using said chosen modality.

  • ULTRASONIC MEASUREMENT OF pH IN FLUIDS
    Publication number: 20110178402
    Abstract: The present invention pertains to new methods and apparatuses for the determination of pH of a fluid. Applicants have discovered that ultrasonic spectrophonometry (the study and measurement of acoustic spectra) can be used to distinguish conformational changes of albumin and red blood cells in response to pH. In accordance with the present invention, there is provided a method of determining the pH of a fluid based on a pH-dependent conformation of at least one fluid constituent comprising subjecting the fluid to an ultrasonic pulse; detecting ultrasonic spectral data of the fluid constituent resulting from the ultrasonic pulse; wherein the spectral data varies with pH; and then calculating pH from the spectral data.

  • Diagnosis of edema
    Patent number: 6332091
    Abstract: Pulmonary edema in the lung is detected by exposing a lung under investigation to infrared radiation, especially near-infrared radiation; measuring the reflected radiation scattered by the lung as a spectral response to the presence of water in the lung; comparing the reflected radiation with calibrated values and evaluating occurrence of pulmonary edema from the comparison.
