Abstract: An optical arrangement for use in spectrometry uses a masking device which eliminates unwanted spectral regions prior to optically resolving the unmasked information. The optical arrangement comprises an entrance slit to select incidence spectral energy from an energized source and a concave grating of relatively low dispersion to image the spectrum of the entrance slit onto a stationary mask which simultaneously selects spectral regions of the dispersed incident spectral energy. The selected spectral regions are collimated and recombined and directed onto an Echelle grating to disperse with high resolution the selected spectral regions. A concave mirror focuses the dispersed selected spectral regions into a focal plane of highly resolved spectral energy which can be detected to determine the spectral information coming from the source. The optical arrangement is particularly well suited for use with narrow spectral bandwidth spectral information distributed over a large spectral range. In spectroscopy, desired information very often occupies a tiny fraction of the total spectral information presented to a spectrometer. With this optical arrangement, spectral information can be selected from a much broader band spectral information and collected with high resolution on a small curvilinear portion of the output focal plane. The arrangement is particularly useful for absorption, light scattering or emission spectroscopy. It provides a stable mechanical design making it less sensitive to vibration. Manufacturing mechanical tolerances are also less restrictive.

Abstract: Method for locating a fault on a power line and equipment for carrying out the method. The power line located between two stations (P,Q), the line being included in a multi-phase distribution or transmission system. The voltage distribution along the line, seen both from station P to station Q and from station Q to station P, is obtained with the aid of a device comprising a travelling wave model of the line located in measure stations (P,Q) at either end of the line. A voltage ΔU Op  is formed as the difference between the voltage in station P, calculated in the travelling wave model in station Q and the corresponding voltage one period/half-period earlier. A voltage ΔU Pp  is formed as the difference between the voltage in station P, calculated in the travelling wave model in station P and the corresponding voltage one period / half-period earlier. The corresponding voltage differences ΔU Pp  and ΔU Oq  are calculated for station α. The voltage difference AP is then formed as the difference between ΔU Op  and ΔU Pp , and the corresponding voltage difference ΔQ is formed as the difference between ΔU Pq  and ΔUOq. The fault distance PF is then obtained as PF = AP PQ/(ΔP + ΔQ), where PO is the distance between the stations.

Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes. Each sample can be taken to a selectable resolution. A watchdog circuit monitors the microprocessor to ensure that it is operating within a preselected time limit.

Abstract: A pulse measurement circuit for measuring timing parameters includes main and delayed trigger generators and a timer for measuring the time between generation of the two trigger signals. The circuit further includes an adjustable delay circuit that senses the main trigger signal and in response enables the delayed trigger generator for triggering after a selectable delay. To measure a timing parameter of a pulse, both trigger generators are first caused to trigger on the first parameter boundary and the time between generation of the two trigger signals is measured. The delayed trigger generator is then caused to trigger on the second parameter boundary while the main trigger generator again triggers on the first parameter boundary. The time difference between generation of the two trigger signals is again measured. The first time is subtracted from the second time to measure the time of the pulse parameter.
