Abstract: A method of arranging an overhead sectional door (SD) in a doorframe (10; 20) that defines a door opening, the overhead sectional door (SD) comprising a plurality of door panel sections (100; 200; 300; 400; 500). The method disclosed herein involves: a) fitting a first door panel section (100) in the doorframe (10; 20), b) fitting a second door panel section (200) in the doorframe (10; 20), and c) actuating an electric motor (M) to cause the first door panel section (100) to push the section door panel section (200) a distance in an upward direction.

Abstract: A method for determining a distance Dsensor between an image sensor and a target area of a driver of a vehicle, comprising arranging a light source at a known geometric relationship with respect to the image sensor, such that a structure in the vehicle at least occasionally casts a shadow in the target area, determining a distance Dlight source between the light source and the target area based on an image acquired be the image sensor of the target area including the shadow and a geometric relationship (e.g. distance) between the light source and the structure, and determining the distance Dsensor based on the distance Dlight source and the geometric relationship between the light source and the image sensor. With this approach, a reliable determination of the distance to the target area may be provided using only one single image sensor.

Abstract: A vehicle coupler including a coupling head and a dampening device attached thereto. A beam is provided and configured to attach to the vehicle. A housing assembly is connected to the beam and configured to receive a portion of the dampening device. A first release mechanism in the form of a shear ring is arranged within the housing assembly and is configured to provide a releasable connection between the dampening device and the housing assembly. A second release device in the form of a plurality of shear elements provides a releasable connection between the beam and the housing assembly. A preload mechanism may also be provided for applying an initial shearing force on the plurality of shear elements.

Abstract: A method for purifying raw methanol containing sulfur compounds, wherein the method comprises the step of washing raw methanol with a non-polar organic solvent.
