Abstract: DRS:VS           PULSE ECHO TECHNIQUE FOR DETECTING FLUID FLOW            Abstract of the Disclosure A method and apparatus for detecting fluid flow behind an acousti-cally reflective structure using pulse echo technique which do not depend upon measurement of a Doppler effect. A transducer is provided for gener-ating a high frequency beam of acoustical energy in the form of pulses.          The transducer is placed proximate, preferably adjacent, the reflective structure such that the acoustic beam is directed toward such structure. A transducer is also provided for detecting the acoustic reflections of the pulses, proximate the position from which the pulses originated, and gener-ating corresponding electrical signal.  An electric circuit is provided for subtracting a pair of acoustic reflection signals separated by a short interval of time to produce a difference signal from which the presence or absence of fluid flow behind the acoustically reflective surface can be determined. In the preferred embodiment, a preselected number of the difference signals are "stacked" by adding the absolute values of such signal to produce a "stacked" signal trace which is more susceptible to evaluation, especially for determination of relative flow velocities.

Title: Configuration fiber-optic blood gas sensor bundle and method of making
Inventor: YIM JEFFREY B
IPC: A61B5/145
Filed: 1991-05-16
Abstract: IMPROVED CONFIGURATION FIBER-OPTIC BLOOD GAS     SENSOR BUNDLE AND METHOD OF MAKING        Abstract of the Disclosure A bundle of fiber-optic sensors that resist breakage, for use in measuring pH, CO2, and O2 concentration, and a method of making the same. Three optical fibers are enclosed in a common polyimide sheath and extend parallel to one another toward a distal end of the sensor, where they are bonded together in a mutually supportive array. At the distal end of one of these optical fibers is disposed a pellet comprising a CO2 analyte indicator molecule codissolved withina polymer matrix. A thin reflective surface of gold foil is provided on the pellet such that incident light transmitted through the optical fiber and polymer matrix is reflected back into the optical fiber. The CO2 polymer matrix absorbs light of a given wavelength to an extent dependent upon the level of CO2 present. Similarly, on the distal end of a second optical fiber is disposed a pH pellet comprising a pH analyte indicator matrix with a thin reflective gold foil attached for reflecting light that has passed through the pH analyte indicator matrix back into the optical fiber. The pH analyte indicator matrix absorbs light of a givenwavelength to an extent dependent upon the hydrogen ion concentration (pH level)of a surrounding fluid. The third optical fiber is used for measuring oxygen concentration. An O2 indicator matrix covers the distal ends of at least two of the three optical fibers; however, at least a portion of the pH optical fiber and the pH pellet are free of the O2 indicator matrix, which is hydrophobic. The oxygen indicator matrix phosphoresces for an interval of time that decreases in proportion to the surrounding oxygen gas concentration. The phosphorescent and reflected light signals are transmitted to light detectors through the optical fibers for comparison to reference signals, so that the analyte concentrations can be determined.

Abstract: OUTPUT PULSE COMPENSATION FOR           THERAPEUTIC-TYPE ELECTRONIC DEVICES          Abstract of the Disclosure Pulse compensation is disclosed for electronic devices capable of producing a pulse output signal suitable for therapeutic purposes with pulse compensation being automatically provided upon sensing of a change in the conditions being monitored.  The electronic device, which preferably includes a micro-computer, has externally accessible pulse width and intensity controls for determining the width and amplitude of pulses then being delivered.  Upon each sensing of a change in a monitored condition capable of causing user discomfort or possible injury, the intensity of the pulses then being delivered is quickly reduced and then gradually increased toward the full intensity requested by the intensity control.  Pulse compensation is also provided when the pulse width is varied by the pulse width control to thereby automatically cause a corresponding change in the range of intensities of the pulses then delivered, based upon a nerve fiber strength-duration curve of the pulses, to thereby maintain the stimulation capability of the pulses substantially constant at a percentage of intensity as determined by the intensity control.
