A fastening device for fastening at least one sensor to a railway rail includes at least one clamping bow and at least two mutually opposite clamping regions connected to the clamping bow. The at least one sensor and at least part of the railway rail can be disposed between the clamping regions. At least one clamping device is connected to the clamping bow for applying the clamping force between the clamping regions for fastening the at least one sensor to the railway rail. A sensor arrangement including the fastening device and a method for fastening at least one sensor to a railway rail are also provided.

A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.

A solar paving module (200) is described. The module (200) comprises: a frame (234); a power generating element (216) comprising at least one photovoltaic element (216) supported in the frame (234); a light transmitting surface screen (218) covering the electrical power generating element (216) and having a planar upper surface; and an electrical connector connected electrically to the power generating element (216). The solar paving module (200) comprises a heat sink (260) in thermal connectivity with the power generating element (216), the heat sink comprising a heat sink plate (262) and one or more ground plates (280) connected to the heat sink plate (262) and forming a heat sink anchor.

A transport facility includes a guide rail which is disposed along a travel path extending in a travel direction through an opening of a wall and which is configured to guide traveling of a transport vehicle, and a fire door configured to open and close the opening. The fire door is configured to, in closing the opening, move toward a first side in an arrangement direction from an open position to a closed position. The fire door includes a notch penetrating the fire door in the travel direction and open on the first side to prevent the fire door from coming into contact with the first rail body and the second rail body while the fire door is moving from the open position to the closed position.

A kinetic energy harvesting device implementing a half-wave mechanical motion rectification (HMMR) mechanism is described. The energy harvesting device may include an energy harvesting railroad tie, where the tie includes a tie housing configured to be coupled to at least one rail. The tie housing includes at least one spring and at least one energy harvester. The at least one energy harvester includes a generator having an output shaft, a gearhead, a ball screw or other motion transmission, and a one-way clutch. Under a force of a passing wheel on the at least one rail, the at least one energy harvester is compressed, which causes a rotation of the ball screw or other motion transmission, a rotation of the output shaft, and a transmission of torque to a shaft of the gearhead, driving the generator in a unidirectional rotation to generate electrical power via the one-way clutch.
