Abstract: In an arrangement of a traffic infrastructure and an optic sensor system (10, 20), the traffic infrastructure has a traffic carrying surface (51) for providing support of conveyance elements (92) of a vehicle (90), therewith allowing movements of the vehicle over the traffic carrying surface. The optic sensor system (10, 20) comprising an interrogator (10) and at least one fiber optic sensor (20) arranged below the traffic carrying surface that is coupled to the interrogator. The at least one fiber optic sensor (20) comprising an optic fiber (21) with a plurality of optic strain-sensor elements (22) distributed over its length. The plurality of optic strain-sensor elements (22) have mutually different optical characteristics, e.g. a mutually different characteristic wavelength. The interrogator (10) is configured to transmit an optical interrogation signal into the at least one fiber optic sensor, to receive a response optical signal modulated by said fiber optic sensor, and to identify changes in the optical characteristics of the response optical signal resulting from strains induced in said optic strain-sensor elements as a result of a conveyance element (92) of a vehicle (90) moving over the traffic carrying surface (51) across said at least one fiber optic sensor. wherein the at least one fiber optic sensor (20) extends at least substantially according to a straight line in a direction at least substantially parallel to the traffic carrying surface.

Abstract: The present document relates to a piston corer for acquiring a soil sample. The piston corer comprises a sample reception cylinder for taking in and retaining the soil sample, and which comprises a piston. The piston is moveable over a piston stroke inside the sample reception cylinder. An intake opening at a first end of the sample reception cylinder allows to receive the soil sample upon penetration of the ground, and the piston is configured to move in a direction away from the intake opening during taking in of the soil sample towards an end position of the piston stroke. The piston corer further comprises an activator cooperating with a valve arranged for closing of the intake opening upon activation. The activator is configured for activating a closing action of the valve in response to the piston reaching the end position of the piston stroke. The document further relates to a method of acquiring a soil sample using such a piston corer.

Abstract: The invention relates to an optical sensor device comprising a reference body, an optical fiber including an intrinsic fiber optic sensor, and a hydraulic transmission system. The hydraulic transmission system is connected to the reference body such that an input portion and an output portion are movable with respect to the reference body. The optical fiber is connected with a first connecting portion to the output portion of the hydraulic transmission system and with a second connecting portion to an element exterior to the hydraulic transmission system. The intrinsic sensor is positioned between the first and second connecting portion. The input portion is arranged for receiving an input action and the hydraulic transmission system is arranged for converting the input action to a sensing action applied to the optical fiber by the output portion such as to modify strain in the optical fiber dependent on said input action.

Abstract: The present document relates to a pressure sensor comprising a structural element, the structural element comprising a first and second structural part. The sensor further comprises a first cavity being in fluid connection with an exterior of the sensor for establishing a first pressure which is dependent on an external pressure in the first cavity and a second cavity configured to be at a second pressure in use. A deformable structure is deformable dependent on a pressure difference between the first pressure and the second pressure. The sensor comprises a fiber including an intrinsic fiber optic sensor fixed to the structural element and to the deformable structure for providing an optical sensor signal dependent on said pressure difference.
