摘要： The present invention relates to a method of calibrating a humidity sensor device, comprising the steps determining a first dew point and a first relative humidity at a first temperature in an environment by the humidity sensor device using a first calibration offset; subsequently heating the humidity sensor device, in particular, by self-heating, thereby heating the environment to a second temperature higher than the first temperature; subsequently determining a second dew point at the second temperature by the humidity sensor device; subsequently determining whether the determined second dew point differs from the determined first dew point by more than a predetermined difference; and subsequently changing the first calibration offset of the humidity sensor device by a predetermined value to obtain a second calibration offset, if it is determined that the determined second dew point differs from the determined first dew point by more than the predetermined difference.

摘要： The present invention relates to a radiation sensor, in particular for use with a vehicle sunload sensor arrangement. Furthermore, the present invention also relates to such a vehicle sensor arrangement and to a method of assembling a vehicle sensor arrangement. A radiation sensor comprises at least one first and one second photodetector, and a radiation shaping element, wherein said radiation shaping element comprises radiation blocking means for forming at least one aperture through which the radiation has limited access to said first and second photodetectors, and wherein said first and second photodetectors are arranged on a substrate and are distanced apart from each other along a sensor axis, and wherein the radiation blocking means is formed by a radiation screen mounted on the substrate to encompass the first and second photodetectors.

摘要： A urea sensor protection assembly for protecting a fluid sensor of a urea sensor system comprises an inner cage supporting the fluid sensor and an outer cage. The inner cage has a first fixation element fixing the inner cage to a common holder. The outer cage has a filter capable of blocking a plurality of air bubbles and/or allowing a fluid to pass and a second fixation element fixing the outer cage to the common holder. The inner cage is at least partially arranged in an inner volume of the outer cage in an assembled state.

摘要： There is disclosed a capacitive sensor on a passivation layer of a semiconductor circuit such as an ASIC, and a method for manufacturing such sensor. The system and method may comprise: forming a bottom electrode layer and landing pad on a portion of the passivation layer located over active circuitry of the ASIC; forming a gas sensitive layer onto the bottom electrode layer and the landing pad; creating a via through the gas sensitive layer to expose a portion of the landing pad; forming a top electrode layer onto the gas sensitive layer, wherein the top electrode layer completely overlays a surface area of the bottom electrode layer, and wherein the forming process for the top electrode layer deposits a portion of the top electrode layer into the via hole, thereby forming an electrical connection between the top electrode layer and the landing pad.

摘要： The invention comprises a method and an analysing system for determining a quality of a hydrocarbon fluid. In an example, the electrical resistivity of the fluid is determined by means of a sensor device. The electrical resistivity is determined over time under predetermined conditions, and a change in the electrical resistivity is monitored over time. A change in fluid visocity may also be determined and monitored over time. The analysing system provides information about an absolute value of a difference of a total base number and a total acid number based on the monitored resistivity change that relates to the quality of the fluid for providing an indication of the remaining useful life of the fluid. In an example, the information about the fluid may correlate to oxidation and/or nitration of the fluid when a change in fluid visocity is below a predetermined threshold.

摘要： A method provides a diagnostic on a combined humidity and temperature sensing device including a humidity sensor having a humidity sensing element, a temperature sensor, and a heater. The method comprises obtaining a first temperature and a first relative humidity, heating the humidity sensing element with the heater, obtaining a second temperature and a second relative humidity after heating the humidity sensing element, and determining a difference between the first temperature and the second temperature and a difference between the first relative humidity and the second relative humidity. Diagnostic information representative of a possible malfunction of the humidity sensor is output when the difference between the first temperature and the second temperature is higher than a predetermined temperature difference threshold and the difference between the first relative humidity and the second relative humidity is lower than a predetermined humidity difference threshold.
