Patent AU-7716887-A (AU)
Title: Method and apparatus for the automatic calibration of signals employed in oximetry
Inventor: CHEUNG PETER WING-POON
IPC: A61B5/00
Filed: 1987-08-18
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).

Title: Update marker system for navigation of an automatic guided vehicle
Inventor: BLOOMFIELD BRYAN ALEXANDER
IPC: G05D1/02
Filed: 1991-10-07
Abstract: An improved accuracy position and direction updating system for use with an automatic guided vehicle that navigates by dead reckoning. Permanent magnets providing detectable position indicators are mounted in the floor and may be at widely spaced locations such as fifty feet apart along the route of the vehicle. A row of Hall sensors is transversely mounted on the vehicle. The sensors detect the lateral location of each floor magnet relative to the vehicle as the vehicle passes over the magnet. Sensors are precalibrated, correcting for errors in sensor null voltage readings due to changes in sensor characteristics due to causes comprising aging and temperature. Data from five sensors that are closest to the magnet are correlated with a stored pattern of magnetic field and their position data are averaged to determined a first estimate of the lateral or first dimensional position of the vehicle. A running average is calculated from sequentially acquired estimates to improve the results. Such precalibration and averaging provides an improved accuracy of the lateral or first dimensional position measurement between the array of Hall sensors and the magnet. A high frequency measurement of the time at which the signals from the row of sensors reaches a peak value, which is the time that the row of sensors arrives at the magnet, provides an improved second dimensional position measurement. More than one magnet is read concurrently to provide position and bearing information during one processing cycle.
Patent AU-9112791-A (AU)
Title: Downward compatible agv system and methods
Inventor: YARDLEY JAMES V
IPC: G05D1/02
Filed: 1991-11-25
Abstract: An automated guided vehicle (AGV) control system which is downward compatible with existing guidewire systems providing both guidewire navigation and communication and autonomous navigation and guidance and wireless communication between a central controller and each vehicle. Vehicle steering and control includes autonomous guidance and navigation of the vehicle over paths marked by update markers which may be spaced well apart, such as fifty feet. The control system employs high frequency two-way data transmission and reception capability over the guidewires and via wireless communications. The same data rates and message formats are used in both guidewire and wireless communications systems. Substantially the same communications electronics are used for the central controller and each vehicle. Novel navigation and guidance algorithms are used to select and calculate a non-linear path to each next vehicle waypoint when the vehicle is operating in the autonomous mode. The non-linear path orginates with an initial direction equal to the heading of the vehicle as it enters the path and a waypoint heading defined as part of the message received from the central control system which plans and controls travel of each vehicle in the system.

Date Jul. 9, 1992When a video signal including a component modulated onto a subcarrier (such as a PAL signal) is subjected to a non-linear pre-emphasis known for MAC signals, with the object of reducing the effects of noise encountered in transmitting the composite signal through an f.m. channel, problems of noise and differential gain remain. These problems are overcome by subjecting the composite signal to a filtering step, before application of the non-linear processing, so as to filter out the subcarrier, the chrominance subcarrier in a PAL signal, and to compand the chrominance sidebands. Preferably a notch filter is used which has a notch shaped as a Gaussian curve.
Patent AU-9467398-A (AU)
Title: A method of purifying waste gases, and a gas burner
Inventor: LINDSKOG NILS
IPC: F01N13/02
Filed: 1998-09-29
Abstract: A method of cleansing nitrogen oxide (NOx), hydrocarbon (HC) and carbon monoxide (CO) from waste gases, such as the waste gases or exhaust gases originating from burners and internal combustion engines. The waste gases, or exhaust gases, are passed through a catalyst for catalytic cleansing of the gases. The air-fuel ratio, or the lambda value (L), is reduced to a level below L=1. The gases are passed through a first catalyst and then through a second catalyst, to bring the CO-content of the gas in the first catalyst to a sufficiently high level and to reduce NOx to N2 to an extent such as to bring the NOx content down to a predetermined level. Sufficient oxygen (O2) is delivered to the gases at a point between the first and second catalysts to oxidize both CO and HC to CO2 and H2O to such an extent as to reduce the CO-content of the gas to a predetermined level. A gas burner to carry out the method is also disclosed.
