| 20090017551 | Method and device for the detection of hydrogen - The present invention relates to a device and a method for the detection of hydrogen in a gas volume by means of an exothermal catalytic recombination of hydrogen and oxygen present in the gas volume into water. The amount of energy that is released during such an exothermal catalytic recombination is measured in the form of a temperature difference and is compared with a stored limit value. When a corresponding limit value is exceeded an appropriate signal is output. | 01-15-2009 |

| 20120045844 | METHODS AND APPARATUS FOR MEASURING ANALYTES USING LARGE SCALE FET ARRAYS - Methods and apparatus relating to very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis. | 02-23-2012 |

The sensor assembly can include a light source; a first hydrogen detection section, the first hydrogen detection section being optically coupled to the light source for receiving light from the light source, wherein the first hydrogen detection section has a first hydrogen sensitive layer that changes an optical response with respect to the received light depending on whether an amount of hydrogen at the first hydrogen sensitive layer is above or below a first threshold; and a first output section optically coupled to the first hydrogen detection section for receiving light having interacted with the first hydrogen sensitive layer such that the received light depends on the optical response of the first hydrogen sensitive layer. | 09-18-2014 |
| 20140273262 | CATALYTIC COMBUSTION TYPED GAS SENSOR - Provided is a catalytic combustion typed gas sensor of detecting a combustible gas having a concentration equal to or more than a predetermined value based on a raised electric resistance. Herein, combustion heat generated when a combustible gas contacts to a catalytic metal (or detection element) heated by passing electric current therethrough raises a temperature and electric resistance of the catalytic metal. The electric current is made to pass through the catalytic metal such that the temperature of the catalytic metal becomes a standby temperature which is calculated by subtracting the raised temperature portion from a desorption temperature. The combustion heat is generated when the combustible gas contacts to the catalytic metal. Note the catalytic metal adsorbs a silicone compound via a silicon (Si) poisoning process and then desorbs the resulting adsorbed silicone compound at the desorption temperature. The desorption temperature is set in the range over 350° C. to 600° C. | 09-18-2014 |
