A sensor device for placement on a rail track and a method for placing the sensor device. The sensor device includes one or more permanent magnets positioned such that the sensor device is mountable on the lateral side of the rail track by magnetic attraction. A housing includes a base side, a mounting side, and a top side opposite the base side, where the mounting side includes first, second and third contact edge regions configured to be in contact with the rail track. The second contact edge region is positioned outwardly from a first plane through both the first contact edge region and the third contact edge region, and the second contact edge region is positioned between a second plane parallel to the top side and through the first contact edge region and a third plane parallel to the second plane and through the third contact edge region.

The invention relates to a switch cabinet with a switch cabinet door which closes the switch cabinet and has a door lock which can be actuated via a door handle, the switch cabinet door having a door status sensor which has a magnetic field sensor being adapted to distinguish an open state of the switch cabinet door from a closed state of the switch cabinet door by means of a detected magnetic field change, characterized in that at least the magnetic field sensor of the door status sensor is accommodated within the door handle in a region of the door handle which is magnetically permeable to the environment of the switch cabinet.

Disclosed are a multi-line source ground-borehole transient electromagnetic detection method and a multi-line source ground-borehole transient electromagnetic detection device. The method includes following steps: S1, constructing a multi-line source ground-borehole transient electromagnetic forward model; S2, obtaining multi-line source ground-borehole transient electromagnetic responses of an underground target layer by the multi-line source ground-borehole transient electromagnetic forward model; and S3, recognizing the underground target layer according to electromagnetic diffusion characteristics of the multi-line source ground-borehole transient electromagnetic responses. A resolution and a detection capability of the underground target by a ground-borehole transient electromagnetic method is greatly improved by adopting technical schemes.

A method for locating an object of interest using offset. The object may be a mobile platform, or portion of same, associated with a vehicle, or a pavement segment or feature of or on a pavement segment on which the mobile platform is located. The vehicle includes first and second fixed points having a known offset from each other. An image sensor whose field of view includes the second fixed point and a portion of the mobile platform provides image data which is used with the known offset to calculate the precise location of the object of interest.

Methods and apparatus for evaluating an earth formation for generating a numerical model comprising an expression equating a representation for the effective conductivity under Archie's law with respect to direct current with a function for the effective conductivity representative of the mixing model with respect to direct current; and solving a system of equations to obtain values for the Archie parameters including at least i) the expression; ii) a second expression equating a first order variation of the representation with a first order variation of the function with respect to water saturation of the formation (Sw); and iii) a third expression equating a first order variation of the representation with a first order variation of the function with respect to porosity of the formation (φ). The second and third expressions may equate derivatives of the representation with derivatives of the function.
