Abstract: An intravaginal and intrauterine sensor for transillumination of a blood-perfused portion of fetal tissue to measure light extinction. The sensor comprises at least one light source (21, 23) and at least one photo-sensor (20, 22) with a shielding (30). The sensor may be mounted onto a paddle-shaped probe provided with signal connections (25, 26) contained in an insulated cable (27) leading to a measurement device. Alternatively, the sensor may include an opaque suction cup or other attaching apparatus for disposition on a protruding portion of the fetus. Most preferably, the sensor includes a housing.

Abstract: A graphics coprocessor adapter with hardware support for horizontal scrolling is disclosed. A graphics processor provides both a row address with a RAS signal and a column address with a CAS signal to two banks of video RAMs. Both banks are provided with the same scrolling column address signal. Translating logic intercepts the column address signal for the static plane RAM bank and translates it into a fixed value. Thus, a single column address signal can control both the scrolling and static planes.

Abstract: A method and apparatus for improving the calculation of oxygen saturation and other blood constituents by non-invasive pulse oximeters. The method and apparatus permit more accurate determina­tion of blood flow by collecting time-measures of the absorption signal at two or more wavelengths and processing the collected time-measure to obtain composite pulsatile flow data from which artifacts have been filtered. The processing occurs in the frequency domain. The time-measure is Fourier trans­formed into its spectral components to form the composite information.

Abstract: The oximeter for cooperation with an oximeter probe comprises decoding means responsive to encoded signals for selecting appropriate calibration coefficients for use in calculating oxygen saturation based upon the known wavelength of first and/or second light emitting means (10, 132 and 20, 130, resp.) in the probe.
A probe comprises a pair of light emitting means preferably diodes (10, 20, 130, 132) which emit light of narrow wavebands having known characteristic wavelengths through part of a patient onto a photosensor (30, 38). A coding means comprising resistor (40) of coded known resistance or else an eight bit connector (52′) is used to enable the oximeter to calculate the coefficient of extinction of the wavelengths of the LEDs. The resistor, LEDs and photosensor are mounted on self-attaching hook and eye tape (50) for mounting the probe onto the appendage of the patient. The probe is detachably wired to the oximeter, rendering the probe completely disposable. The oximeter is programmed at the factory to calculate the co-efficients of extinction of any LEDS which may be encountered in a series of disposable probes. From the co-efficients of extinction, the pulse rate and degree of arterial oxygen saturation is computed and displayed by the oximeter.
