Abstract: In this method for producing capacitive alumina-ceramic absolute pressure sensors sorted in high-precision zero-point long-term stability defect classes referred to a measured-value span csp, the sensors are firstly produced conventionally: a substrate is provided with an annular first electrode and, at the center, a circular second electrode insulated from the first; a diaphragm is provided with a third electrode, and the substrate and diaphragm are joined tightly together in a vacuum by the mutually facing electrodes, at an outer edge through the interposition of an active brazing ring with the formation of a chamber, with the result that a pressure-dependent capacitance Cp and a pressure-independent capacitance Cr are produced. Then, using the equation c = (Cp-Cr)/Cp = k1(p-p0)+k0, at room temperature and under a vacuum (= p --> 0 ) a first zero value cn2 = -k1p0+k0 is determined by means of a capacitance zero-point measuring device having the zero-point measuring error Fn. A second zero value cn2 = -k1p0 ' +k0 is determined f or each sensor by means of the same measuring device after the sensors have been stored in a gas during a period t in such a way that the pressure and/or temperature of the gas was raised, or its molecular weight was lowered, with respect to normal atmospheric conditions. Then the difference .delta.cn between the first and second zero values .delta.cn = cn1 - cn2 k1.delta.p0 is formed, and the value .delta.cn/csp is compared with the value Fn/csp. It is also possible to make use analogously of the zero-point temperature coefficient.

Title: Methods to fabricate dense wavelength division multiplexers
Inventor: YIP LAP SUM
IPC: G02B6/36
Filed: 1997-03-14
Granted: 2002-08-13
Abstract: Methods for the fabrication of dense wavelength division multiplexers (DWDM) are disclosed. In one embodi-ment, an array of micro membranes and an array of cavities for optical fibers are etched in a substrate. The distance between major surfaces of adjacent micro membranes is con-trolled during the etching step. Multilayer narrow bandpass filters are then deposited on all micro membranes simultaneously by vacuum deposition methods. Due to the controlled separation between adjacent micro membranes, the central wavelength of transmission either increases or decreases from one membrane to another. In another embodi-ment, a micro machined structure containing a plurality of cavities and a slot for a variable narrow band pass filter is fabricated. The variable narrow band pass filter is aligned with respect to the optical fibers to obtain a WDM.

Granted: 2007-03-20
Abstract: Apparatus and method for detecting patient sample quality, and/or analytes, in the tip used to aspirate the patient sample liquid and then dispense it onto a slide test element. Spectrophotometric analysis is done on the liquid while still in the tip, by scanning the tip for transmittance in a light-tight enclosure, using NIR and adjacent visible radiation, and detecting the absorbence spectra of the liquid. Thereafter, or prior thereto, the liquid is dispensed onto a dried slide test element for assaying analytes that are not assayed spectrophotometrically, thus enhancing throughput. Much smaller liquid volumes, and no through-the-label detection, are required, compared to doing the scanning of the liquid in a primary patient collection container.

Abstract: A zirconium oxide shell forms a chamber of fixed volume, and a controller monitors voltage across the shell indicative of the difference between inside and outside oxygen levels, applying a signal to pump oxygen. Integrated pump current yields a measure of the oxygen added to or removed from the chamber. The sensor material is a mixture of about 91% zirconium oxide and 9% yitrium oxide, with porous electrodes on each surface. The controller may apply a sequence of current pulses, checking the Nernst cell output indicative of .DELTA.P across the wall, until .DELTA..P=0. Positive and negative pulses may be tallied in a running sum to determine the present reading. The processor adds the present differential as a correction to the last stored reading to provide the oxygen level as an immediate output.
