Abstract: Aspects of the invention relate to a semiconductor chip comprising a substrate and a stack arranged on the substrate. The stack comprises one or more insulating layers and one or more metal layers. The chip comprises a sensor device arranged in a sensor area (SA) of the semiconductor chip and processing circuitry arranged in a processing area (PA) of the semiconductor chip. The chip further comprises connection circuitry configured to provide an electrical connection between the sensor device and the processing circuitry. A first seal ring structure is arranged between an outer edge (ED) of the chip and an inner area (IA) of the chip. The inner area (IA) of the chip encompasses the sensor area (SA) and the processing area (PA). A second seal ring structure is arranged between the sensor area (SA) and the processing area (PA) and configured to constrain an infiltration of contaminants from the sensor area (SA) to the processing area (PA).

Abstract: A flow sensor arrangement for determining the flow of a fluid comprises a substrate. A heater is arranged in or on the substrate as well as at least one first thermocouple for generating a first signal proportional to a temperature difference between a location downstream from the heater and a first reference location, and at least one second thermocouple for generating a second signal proportional to a temperature difference between a location upstream from the heater and a second reference location which second reference location is different from the first reference location. In addition, at least one third thermocouple is arranged in or on the substrate for generating a third signal proportional to a temperature difference between the first reference location and the second reference location.

Abstract: A fiber-optic current sensor includes a measuring unit having a light source and a light detector, and a sensing head having a sensing fiber wound around a conductor and a retarder connected to the sensing fiber. The scale factor as a function of current of the fiber-optic current sensor is described by the product of two scaling functions fe? and fs? for the measuring unit and the sensing head, respectively. The data describing the scaling functions fe?, fs? is stored in a memory of the measuring unit, while the data describing the scaling function fs? is also stored in a memory of the sensing head. Providing two such memory devices allows to store the scaling functions fe? and fs? separately, thereby turning the control unit as well as the sensor head into easily replaceable modules.

Abstract: The present disclosure relates to the field of treating atmospheres that are laden with substances that are nauseating and/or detrimental to human or animal health, specifically to the field of deodorising, perfuming, and/or purifying air at industrial or private sites. For this purpose, there is disclosed a method for enriching, preferably saturating, ordinary atmospheric air with active substances present in the gas phase, to a device for implementing the method, and to the use of the method for the treatment of polluted atmospheres. The method is especially characterized in that it advantageously includes a step of reinjecting a portion of the enriched gaseous mixture (MG) into an enrichment or saturation chamber (7) in order to increase the enrichment rate of the gaseous mixture (MG) or to maintain the mixture at the maximum saturation level thereof.

Abstract: The invention relates to a method for deodonising large-scale plants, in which solid or liquid malodorous materials are stored, by means of treatment of the unpurified air above the surface of the malodorous materials with active agents which react with or mask malodorous substances in the air. The active agents are dispersed in a matrix of polymers comprising cross-linked hydrophilic groups and together with the above form a spongy mass from which the active agents are slowly released and vaporised. The spongy material is incorporated between two parallel plates (3), which are mounted above the surface of the malodorous materials or at the edge of the large-sized plant and an airflow runs between the plates (3) and releases the active agents.

Abstract: A measuring apparatus is provided with a stylus (30), including a column (12), a carriage (14) slidably mounted on the column (12) and a stylus carrier (32). The stylus carrier (32) carries the stylus (30) and is secured to the carriage (14). The stylus carrier (32) is provided with a bar (42) and a support (44). The support (44) is secured to one of the ends of the bar (42). The stylus (30) is secured to the support (44). The carriage (14) is provided with two supports (54, 56) arranged longitudinally on one of the sides of the slide (52), one at each of its ends. The two supports (54, 56) are in contact with one of the faces of the bar (42). A locking member (58) is formed of a lock (74) and cooperates with the other face of the bar (42). A spring (78) generates a blocking force (F) which applies the lock (74) against the bar (42). The force (F) is oriented along an axis passing between the two supports (54, 56).
