摘要： A system and method for monitoring the contact of tool bits of a lathe with surfaces of a brake disk being machined employs a vibration sensor coupled to the lathe. Signals from the vibration sensor are processed as time-averaged segments that can be grouped within time intervals; a microprocessor employs a qualifying routine to compare the signal level to a background noise threshold value and indicates as “failed” those time periods where the average signal level is not above the background noise threshold. An accumulator records the indications over a number of intervals and compares the result to a standard to make a determination of whether the lathe is likely actively cutting the disk surfaces. To isolate intermittent, high-intensity noises, a consistency routine can check further to see whether individual segments within an interval fall within a range based on the average signal level for that interval.

摘要： The invention discloses several computation and control techniques which use historic information as well as other cues in order to enhance the accuracy of a radio position fix. These computational techniques include neural networks, mapped grid coefficients as input to a set of simultaneous or differential equations, and table lookup of correction coefficients for known low accuracy positions. The invention further discloses techniques for receiver array synchronization so that all system elements in a particular coverage area obtain a time reference appropriate for time of flight radio location measurements. The invention further teaches techniques to enhance the accuracy of a position fix by use of both fixed references, which are located in a coverage area, as well as a mobile reference carried by a search team. The invention also discloses techniques to provide information appropriate to guide a search team to an unknown positioned transmitter that is located within a building or structure. The invention discloses techniques to train a central computing unit, by using actuarial data, so that multi-path errors resulting from fixed or mobile obstacles may be reduced.

摘要： Three fixed reference stations having known positions comprise Omega receivers. Phase measurements made at all three stations are assembled at a master station, utilizing landlines or radio links and, using the known positions of the stations, a central processing unit calculates not merely the offset of the master station as measured from the true position but also the errors in the azimuths of the propagation directions of the received signals. The position measurement of a vehicle with an Omega receiver is corrected on the basis of the offset and also the errors in the said azimuths. Sufficient accuracy is achieved for finding the position of land based vehicles whose position may be calculated subject to the corrections in the master station on the basis of raw data transmitted to the master station over a link. Alternatively the azimuth corrections may be transmitted to the vehicle over the link. Two fixed stations suffice if they can measure absolute phase.
