Abstract: Under the present invention, a method and apparatus are provided for compensating for the effect temperature variations have on the wavelength of light emitted by the oximeter sensor light sources (40, 42). In pulse oximetry, LEDs (40, 42) are typically employed to expose tissue to light at two different wavelengths. The light illuminating the tissue is received by a detector (38) where signals proportional to the intensity of light are produced. These signals are then processed by the oximeter circuitry to produce an indication of oxygen saturation. Because current oximetry techniques are dependent upon the wavelengths of light emitted by the LEDs (40, 42), the wavelengths must be known. Even when predetermined combinations of LEDs (40, 42) having relatively precise wavelengths are employed, variations in the wavelength of light emitted may result. Because the sensor (12) may be exposed to a significant range of temperatures while in use, the effect of temperature on the wavelengths may be significant. To compensate for this effect, a temperature sensor (50) is included in the sensor (12) to produce a signal indicative of sensor temperature. This signal is interpreted by t he oximeter circuitry including, for example, a microcomputer (16), where the effect of temperature on wavelength is compensated for. In a preferred arrangement, this compensation takes the form of a computation of an alternative calibration curve from which the oxygen saturation is indicated, given a particular processing of signals from the detector (38).

Abstract: A circuit is disclosed which combines the functions of a cyclic redundancy check code (CRCC) generator and a pseudo-random number generator in such a way that common elements are shared rather than duplicated. A 16-stage shift register and two linear feedback paths are included for the CRCC and pseudo-random number generators. A control section of the circuit controls the mode of operation of the circuit according to the state of a mode control signal. A signal on a clear line resets the shift register or initializes it with a selected value depending on the state of the mode control signal. The mode control signal also controls the input of data on a data line and the output of generated CRC and pseudo-random access codes on output lines.

Abstract: This invention concerns, in brief, means of and devices for measuring the flow rate of liquids, as well as equipment for controlling the spray patterns of farm sprayers in which measurements of flow rate according to the invention are included. The liquid to be measured is led into a measuring cylinder (8) whereby the level of the liquid in the measuring cylinder provides a measure of the flow rate. By keeping the level (9) constant by means of level sensors (10) and a control unit (12), together with a pump (12) governed by the control unit, the liquid is pumped through a flow meter (14) which, without losses, gives a rapid and reliable measurement of the flow rate. This method of measuring the flow rate is utilized in equipment consisting of a trolley, which runs on a track and which collects in a collection channel the spray emitted from nozzles. The part of the spray liquid which is caught by the collection channel is measured with regard to flow rate and these measurements are done either stepwise or continuously along the nozzle boom, whereby a total picture of the sprayer's condition is obtained.
