The system also includes the following elements: a data collector for monitoring certain portions of a user's computer activity and for logging into a log file those certain portions of a user's computer activity; a data analyzer for determining by following user-defined rules showing which portions of those certain portions of a user's computer activity constitutes continuous work activities, and how this work should be categorized by project and task with project; and an external interface for building the rules defining work. The data collector includes a resident module, such as a TSR (terminate-and-stay-resident) module, which extends the file system of the computer so that detailed records are kept of file activities.

Abstract: Line voltage and line current signals are sensed on a power line having at least one conducting path. The sensed line voltages and line currents are converted into a digital signal. A phase-to-neutral voltage signal and phase current signal are computed from the digital signal to thereby define a phase of the power line. An interval of orthogonality is determined from the sensed voltage and current signals, coinciding with passage of an integral number of cycles of a fundamental frequency reference signal which is computed from the computed phase-to-neutral voltage signal. A vector metering quantity is computed for the determined interval of orthogonality from the computed phase-to-neutral voltage signal and the computed phase current signal. The vector metering quantities to be computed may be identified and computed based upon an associated detent. The vector metering quantity is also computed based on an identified circuit topology.

Abstract: A method for measuring a fluid flow rate between two points of a fluid flow according to which a measurement of the respective propagation times of two acoustic signals transmitted in opposite directions is combined with a measurement of acoustic phase shifts respectively induced in each signal. Each received signal is sampled and digitized and the corresponding acoustic phase shift is determined by synchronous detection. During successive iterations, a programmable phase shift dependent on the value of the acoustic phase shift obtained by synchronous detection in the previous iteration is determined for each iteration, so that the result of the synchronous detection step in the current iteration is as close as possible to zero, and the acoustic phase shift is therefore substantially the same as the last programmable phase shift.

Abstract: One or more basis sets are applied to a spectroscopic signal during analysis to produce an accurate spectral representation from which analyte concentration may be accurately determined. A basis set includes all interfering components found in a sample, such as serum. With regard to an analyte, such as glucose, it is necessary to define those components of a sample that have a larger interference than that of glucose. A basis set may be generated, for example, that produces a transform for the red blood cells that interfere or scatter the light; and also for skin effects. Once the spectra of all these components is known, it is then necessary to determine how each of these components interact, e.g. taking serum data, extracting each of the components, and then comparing the spectra for the individual components with that of the components in solution.

Abstract: A weight measuring apparatus comprising a plurality of load sensors, together with an input network, a multiplexer, a reference, an analog to digital converter, and a processor, wherein the input network includes an analog summing network and direct sensor connections to the multiplexer. The multiplexer is arranged to permit measurement of the sum signal, a reference signal, and each direct load sensor signal in a prescribed sequence. The multiplexed signals are converted to digital and processed to derive a weight estimate based on the multiplexed measurements and a system error model. The prescribed measurement sequence permits measurement of the sum signal more frequently than each of the direct signals. A method is described for deriving correction factors for the error model comprising the placing of calibration weights primarily on each weight sensor and solving the system of simultaneous equations for the resulting correction factors.
