Abstract: An inspecting method is capable of efficiently inspecting a wafer. According to the inspecting method, the chip area of a wafer is inspected for defects, and based on the results, a defect density D0p of each of peripheral-zone chips in the chip area which are located closely to the peripheral area of the wafer is calculated. A peripheral-zone chip with a high defect density D0p is selected, and an area in the peripheral area which is outward of the selected peripheral-zone chip is inspected for defects. Since only the area in the peripheral area which is located outward of the peripheral-zone chip selected based on the defect density D0p is inspected for defects, the wafer is inspected efficiently.

Abstract: A method and system for identifying a defect or contamination on a surface of a sample. The system operates by detecting changes in work function across a surface via both vCPD and nvCPD. It utilizes a non-vibrating contact potential difference (nvCPD) sensor for imaging work function variations over an entire sample. The data is differential in that it represents changes in the work function (or geometry or surface voltage) across the surface of a sample. A vCPD probe is used to determine absolute CPD data for specific points on the surface of the sample. The combination of vibrating and non-vibrating CPD measurement modes allows the rapid imaging of whole-sample uniformity, and the ability to detect the absolute work function at one or more points.

Abstract: The present invention relates to a vibration data collection method and apparatus. The invention includes processes of receiving electrical vibration signals from at least one vibration sensor, digitizing the electrical vibration signals to obtain digitized vibration signals, calculating the average of the digitized vibration signals over a predetermined period, and storing the average in a storage device. The processes above are repeated to provide a history of averages. When vibration data recording is requested, the invention proceeds to check the history of averages to determine if the averages within a time period are substantially equal to one another within a tolerance. If the averages are within the tolerance, the digitized vibration signals are recorded.

Abstract: A method and apparatus are provided for calibrating a flow meter having an array of sensors arranged in relation to a pipe that measures a flow rate of a fluid flowing in the pipe. The method features the step of calibrating the flow rate using a calibration correction function based on one or more parameters that characterize either the array of sensors, the pipe, the fluid flowing in the pipe, or some combination thereof. The calibration correction function depends on either a ratio t/D of the pipe wall thickness (t) and the pipe inner diameter (D); a ratio t/? of the pipe wall thickness (t) and the eddie wavelength (?) of the fluid; a Reynolds number (?UD/?) that characterizes the fluid flow in the pipe; a ratio ?x/D of the sensor spacing (?x) and the pipe inner diameter (D); a ratio f?x/Umeas of usable frequencies in relation to the sensor spacing (?x) and the raw flow rate (Umeas); or some combination thereof.

Abstract: A method is disclosed wherewith a person skilled in the art of statistical quality control may determine whether a process, goods, or service is statistically equivalent to another of known quality, or to a desired target quality. The method may also be used to determine whether multiplicities of goods, processes, or services are statistically equivalent to one another and of a desired quality. The method makes the determination based on an equivalency index that is derived from integration of the probability distribution of data of measurement taken from products associated with the process, goods or services.

Abstract: A tire monitor and a tire pressure gauge for reading the data from the tire monitor are disclosed. The tire monitor includes an in-tire controller that stores a target inflation pressure representing the pressure to which the tire should be inflated when the tire is at a standard temperature. The tire monitor transmits the target inflation pressure to the external processor when the external processor is connected to the in-tire monitor over a communication link. A sensor array in the tire monitor can provide pressure and temperature readings that are stored in the monitor and used to provide a temperature-compensated fill pressure for the tire. The tire pressure gauge provides the user with a fill pressure to be used in inflating the tire. The tire pressure gauge communicates with the tire monitor and obtains pressure and temperature readings stored in the tire monitor. These reading are used to provide the temperature-compensated fill pressure.

A signal may be generated that is indicative of signal consistency based, at least in part, on the determination of phase difference between the respective sub-signals. An output module may, for example, effect such a signal generation.

Abstract: Systems and methods for identifying populations of events in a multi-dimensional data set are described. The populations may, for example, be sets or clusters of data representing different white blood cell components in sample processed by a flow cytometer. The methods use a library consisting of one or more one finite mixture models, each model representing multi-dimensional Gaussian probability distributions with a density function for each population of events expected in the data set. The methods further use an expert knowledge set including one or more data transformations and one or more logical statements. The transformations and logical statements encode a priori expectations as to the populations of events in the data set. The methods further use program code by which a computer may operate on the data, a finite mixture model selected from the library, and the expert knowledge set to thereby identify populations of events in the data set.
