| 20110204236 | Super-Miniaturized NDIR Gas Sensor - Two detector elements are optically isolated by having them mounted (die-attached) on the same header so that the thermal tracking of the detectors respectively for the signal and reference channels is close to ideal. Furthermore, such an optical isolation technique or cross-interference suppression between the two detector elements mounted on the same header also allows the use of only one and the same narrow band pass interference filter covering both detectors. Thus the thermal tracking of the filters respectively for the signal and reference channels is also close to perfection as both channels share the same filter. | 08-25-2011 |
| 20110042570 | Absorption Biased NDIR Gas Sensing Methodology - An NDIR gas sensor and methodology use an absorption bias between signal and reference outputs to determine sample concentration of a gas being measured. The absorption bias is created by using a signal channel in a sample chamber with a signal path length that is greater than a reference path length of a reference channel in the sample chamber while both the signal and reference detectors have an identical narrow band pass filter with the same Center Wavelength (“CWL”), Full Width Half Maximum (FWHM) and transmittance efficiency at the CWL. Performance is improved when the reference detector and the signal detector share a common thermal platform that can also be shared by the sample chamber and the infrared source. | 02-24-2011 |
