摘要： This invention permits rapid determination of a three-dimensional contour of an object. The apparatus directs a laser beam onto a point on an object, and the scattered light is received by a position sensitive detector (PSD). The location at which scattered light is received can be related to the displacement of the point on the object, using basic trigonometry. The laser beam is deflected non-mechanically, by passing it through a crystal whose index of refraction is varied in a controlled manner. By proper control of the index of refraction, one can scan the beam across a desired area of the object, without using any moving parts, and can therefore obtain complete information about the contour of the object. The device operates without making any conventional images, and is therefore much faster than comparable devices of the prior art. Also, the laser and beam deflector can be housed in a small optical head which enables the device to reach normally inaccessible areas. The device can compare the test object with a reference object, or it can compare two objects for differences.

摘要： A calibration assembly for a spectrometer is provided. The assembly includes a spectrometer having n detector elements, where each detector element is assigned a predetermined wavelength value. A first source emitting first radiation is used to calibrate the spectrometer. A device is placed in the path of the first radiation to split the first radiation into a first beam and a second beam. The assembly is configured so that one of the first and second beams travels a path-difference distance longer than the other of the first and second beams. An output signal is generated by the spectrometer when the first and second beams enter the spectrometer. The assembly includes a controller operable for processing the output signal and adapted to calculate correction factors for the respective predetermined wavelength values assigned to each detector element.

摘要： An inductive position sensor uses three inductors. First and second inductors are separated by a fixed distance with the first inductor's axial core and second inductor's axial core maintained parallel to one another. A third inductor is disposed between the first and second inductors with the third inductor's axial core being maintained parallel to those of the first and second inductors. The combination of the first and second inductors are configured for relative movement with the third inductor's axial core remaining parallel to those of the first and second inductors as distance changes from the third inductor to each of the first inductor and second inductor. In operation, a source supplies an oscillating current to at least one of the three inductors, while another device measures voltage induced in at least one of the three inductors not supplied with the oscillating current. The voltage so-induced is indicative of an amount of the relative movement between the third inductor and the combination of the first and second inductors.

摘要： A metering data preservation and storage methodology, including steps for protecting data during periods in which power is lost to the meter, is provided. In particular, a methodology for using non-volatile flash memory structures is used in association with various volatile memory structures for the storage and preservation of metering data acquired from a solid-state utility meter. The methodology includes the use of the volatile memory structures for the temporary storage and alteration of the measured and calculated metering data so as to avoid an effective reduction in the lifespan of the non-volatile memory structure which can only be written, erased and rewritten to a finite number of times. Further, such usage reduces costs associated with the maintenance and incorporation of such memory types in the meter. The methodology further includes the use of the non-volatile flash memory as a permanent storage medium for the acquired metering data during power loss to the meter.
