A system and method for obtaining an estimate of the concentration of an odor in an air sample from data obtained by evaluating the sample with a sensor-array type electronic nose. Principal components analysis is applied to a set of air sample data including sensor-array data obtained from evaluating the air sample with the sensor-array type electronic nose and measurements of the humidity of the air sample and clean reference air used by the electronic nose to obtain a predetermined number of ...

A method for setting the measuring states of a haemadynamometer comprises the steps of: actuating the power of the haemadynamometer; measuring blood pressure and displaying the measuring value; selecting the setting or unsetting various states according to the condition of the measurer, and displaying the state values; and finally, accessing the measuring values and the data of state values. Thereby, by the electronic haemadynamometer, the states of the user can be recorded. Then data can be loo...

A system for treating goods, in particular for coating optical substrates, under a vacuum, within a gas-tight sealable, evacuatable vacuum chamber (receiver) that can be provided with an inert gas atmosphere, includes a device for calibrating the gas pressure in the receiver for a respective operating cycle. The calibrating device has a calibration pressure vessel (2) having a volume (v) lower than the volume (V) of the receiver (1) and is connected in terms of flow with an inert gas source and ...

The invention provides a tool and method for monitoring and evaluating any industrial or commercial process, activity or system or the personnel carrying out that process, activity or system against a set of Performance Drivers for the process, activity or system; and for assessing the efficiency, capability or sustainability of that process, activity or system as a result of the monitoring. By utilizing both a weighting between each of the different statements and questions used to derive perfo...

There is provided a method and apparatus for performing an eye scan. Said apparatus comprises: a receiver for receiving input signals; an equaliser for processing said input signals; a data sampler for sampling said processed input signals at certain sampling points to produce a data output, said data sampler being controlled by a clock signal; an edge sampler for detecting the edges of the processed input signal; an early/late voter for deciding whether a current sampling point needs to be adva...

A method and apparatus for statistical compilation is presented. A statistic component portion for each statistic is stored in each a plurality of banks in a multi-location memory. At least one statistical update stream is received. Each statistical update stream includes a plurality of statistical updates, where each statistical update includes a statistic identifier and an update operand. Received statistical updates are scheduled to produce a scheduled update stream. A control block executes ...

Methods and apparatus are provided for receiving, detecting and transmitting geophysical data from a plurality of electrodes placed in the soil utilizing a dynamically reconfigurable wireless control unit that is located on each electrode. Data from the control units is transmitted by a wireless signal to a centralized data processor for analysis. Control data is provided from a central control processor to the control unit by wireless transmission. The control unit, which is positioned, include...

An analog-to-digital converter (ADC) exhibiting an uncorrected non-linear transfer function receives measured analog voltage amplitudes and outputs uncorrected digital values. A calibration circuit receives each uncorrected digital value and outputs a corrected digital value. The measured analog voltage amplitudes received by the ADC and the corresponding corrected digital values output by the calibration circuit define points approximating an ideal linear transfer function of the ADC. The calib...

A technique for estimating and improving the test coverage for large machines, while accumulating minimum information of past test cases (i.e., minimum feedback) is provided. The technique is scalable in the sense that the number of machine instructions needed to measure the test coverage can range from a few instructions to all the instructions. The technique is easily integrated into existing test generation systems and is applicable to both uni- and multi-processing systems.

A test system with multiple instruments. Some instruments act as controller instruments and others act as controlled instruments. Each instrument includes a clock generator that synthesizes one or more local clocks from a reference clock. The reference clock is a relatively low frequency clock that can be inexpensively but accurately generated and distributed to all of the instruments. A communication link between instruments is provided. Timing circuits within instruments that are to exchange t...
