Abstract: A method and apparatus for non-invasively determining the blood oxygenation within a subject's tissue is provided that utilizes a near infrared spectrophotometric (NIRS) sensor capable of transmitting a light signal into the tissue of a subject and sensing the light signal once it has passed through the tissue via transmittance or reflectance.

Abstract: A method and apparatus for calibrating an NIRS system which includes a sensor portion and for evaluating an NIRS system for proper functioning is provided that includes an enclosure with at least two windows disposed in a wall of the enclosure. The windows allow the light source and one or more detectors of an NIRS system sensor to interface with the enclosure. One window is dedicated to the light source while each light detector has a window dedicated thereto. Thus, the enclosure includes a number of windows equal to the number of light detectors in the NIRS system sensor plus one. The inner surface of the wall(s) of the enclosure is of a light-absorbing color; e.g., black. A diffuse reflectance member of a light-reflecting color, e.g., white, is disposed in the enclosure spaced apart from the surface with the windows disposed therein.

Abstract: A method and apparatus for determining at least one characteristic of a fluid flowing within a pipe is provided. The fluid flow may include one or more liquid component bodies and one or more gas component bodies, which bodies occupy a substantial cross-sectional area of the pipe when passing a location in the pipe. The method includes, and the apparatus includes elements operable to perform, the steps of: 1) transmitting a signal into the fluid flow at the location within the pipe, and receiving the signal after it has traversed at least a portion of the fluid flow; 2) determining a time of flight of the signal traversing the fluid flow; 3) determining the presence of a liquid component body at the location in the pipe, using the determined time of flight; and 4) determining at least one characteristic of the fluid using fluid data generated if the liquid component body is present at the location.

Abstract: A method and system is provided for updating a sensor disposed within a mobile unit.
