Abstract: A reconfigurable GPR device for acquiring radar data about a medium includes a radar antenna with a first polarization, a processor unit connected to the antenna, and a casing around the antenna and the processor unit. Further the device includes at least one of a wheel assembly and a direction-determining unit. If present, the wheel assembly includes a holder, a wheel and a wheel rotation sensor. The wheel rotation sensor is connected to the processor unit, and an axis of the wheel is pivotal relative to the first polarization. If present, the direction-determining unit is connected to the processor unit and adapted to determine directional information. The directional information is descriptive of an angle between a direction of movement of the device and the first polarization.

Abstract: A method of gluing a first metal part to a second part includes the steps of providing a first metal part such as a steel part, and the second part such as a second metal part, treating a surface portion of the first metal part intended for being glued to the second part with laser pulses so that a surface layer of the first metal part across the surface portion is removed, preferably by ablation, while applying laser pulses to the surface portion of the first metal part also applying a pressurized air or gas stream to the surface portion, applying an adhesive to at least the surface portion of the first metal part and/or to a surface of the second part, and gluing the first metal part and the second part together.
