Abstract: A device repeatedly measures a characteristic, such as electrical conductivity, of water in a water line. A plurality of the measurements are averaged to arrive at a water quality value. This value is displayed and another plurality of measurements are averaged to arrive at another value, which is then displayed in place of the previous value. The process continues at selected intervals in order to provide a continuous display of the condition of water in the line. Each new value is compared to a reference value representing a maximum acceptable level of contaminants. If the water quality value exceeds the reference value, an overvalue signal is produced, indicating an unacceptable level of contaminants in the water. The repeated measurements are obtained at selected intervals, and a new water quality value may be derived at the same intervals by discarding the oldest of the measurements from the previous plurality and including the most recent measurement to create a new plurality of measurements.

Abstract: A method and a device for signal separation. First, values of signals observed by M sensors are transformed into frequency domain values, and these frequency domain values are used to calculate relative values of the observed values between the sensors at each frequency. These relative values are clustered into N clusters, and the representative value of each cluster is calculated. Then, using these representative values, a mask is produced to extract the values of the signals emitted by V (1?V?M) signal sources from the frequency-domain signal values, and this mask is applied to the frequency-domain signal values. After that, if V=1 then the limited signal is output directly as a separated signal, while if V?2 then the separated values are obtained by separating this limited signal with separation techniques such as ICA.

A display unit produces a visual image on the surface of the tabletop surface and a position tracking system determines the current positions of each of said movable objects by transmitting timed acoustic signals to each movable object, sensing the timing of arrival of these signals using an acoustic pickup on each object, and estimating the location of the object by triangulation. An infrared communications network exchanges timing information, commands and data between the objects and a controller which provides an API to a personal computer which executes an application program that controls the display.

Abstract: Metrology data from a semiconductor treatment system is transformed using multivariate analysis. In particular, a set of metrology data measured or simulated for one or more substrates treated using the treatment system is obtained. One or more essential variables for the obtained set of metrology data is determined using multivariate analysis. A first metrology data measured or simulated for one or more substrates treated using the treatment system is obtained. The first obtained metrology data is not one of the metrology data in the set of metrology data earlier obtained. The first metrology data is transformed into a second metrology data using the one or more of the determined essential variables.

Abstract: A current synthetic UV index is developed and successfully verified against direct surface measurements of UV index values. The purpose of this invention is to distribute this current synthetic UV index through cell phones nationwide. This will inform cell phone users for the first time about the current UV index value when they carry their cell phones. The current UV index will be calculated using the geographical location of the cell phone, the time of the day, and the cloud cover conditions in that area. The algorithm will then use this information to calculate the solar elevation needed to determine the amount of UV radiation reaching the earth's surface at any given time. The total column ozone for that particular day will be taken into account for each calculation. This mechanism of dissemination of the actual/current UV index values will be an important achievement with the intention of raising the public's awareness of the harmful effects of the sun's ultraviolet rays.

Abstract: Precomputed databases of sensor responses are used to convert measurement data into properties of interest, for example, conductivity or lift-off. These databases of responses may be generated prior to data acquisition and provide sensor response values that span appropriate ranges for the property values. After data acquisition, estimates for the property values are obtained from measurement values by minimizing the difference between the database of responses and the measurement values. The minimization can take the form of a least-squares minimization. Alternatively, iterative techniques can be used to minimize the difference between the database and measurement values.

Abstract: An apparatus and method for displaying the weight or cost of an uncut selected segment of an item involves passing a position indicating member over the item lying on a support surface. The position indicating member carries one or more sensors which generate signals corresponding to succeeding cross sectional contours of the item as the member is traversed along the item from a reference position to a selected other position over this item, defining the selected segment of the item. At the same time, a motion detector arrangement preferably comprised of one or more microelectromechanical (MEMS) accelerometer devices generates signals corresponding to motion of the position indicator support member as it is moved along the item. These signals are processed in a signal processor to determine the volume of the uncut selected segment of the item lying between selected successive positions of the indication member.

Abstract: A method and a system are recited for obtaining a true azimuth heading for correcting a coarse azimuth heading measured from an observation position to a specific selected target by operating a data acquisition system disposed at the observation position. In principle, data is acquired and measurements are taken to allow calculation of a calculated target, including error area limits.

Once found, calculations of the true azimuth are performed, allowing the derivation of the true North. The method and a system are operative with a variety of maps, including digital terrain models and stellar maps.

Abstract: A digital power metering system reduces spectral leakage when determining the frequencies present in a power signal by a technique that includes sampling the signal and performing a transformation from the time domain to the frequency domain. The system initially measures the fundamental frequency of the power signal, and samples the power signal at a known sampling rate to produce digital sample values representing the power signal. The system then determines whether the known sampling rate is within a preselected range of a rate that is coherent with the measured fundamental frequency. If the answer is negative, then the system resamples the signal at a rate that is coherent with the measured fundamental frequency to produce resample values representing the signal, so that the frequencies present in the power signal can be determined from the resample values.
