Abstract: A fastening device (1) for a wearable article, the fastening device including four hook elements (2, 3, 4, 5) a central adjustment unit (6) and fastening cord (7). Furthermore, a wearable article with one or two fastening devices is disclosed.

Abstract: An adjustment unit (1) with a main body and an adjustment unit hook element (3) protruding from the main body which can be used in an adjustment device (1), as well as a wearable article with such a fastening device (100).

Abstract: The invention relates to a WIM sensor for detecting loads of vehicles on a roadway segment when a wheel of a vehicle crosses the WIM sensor arranged flush with the roadway surface in the roadway segment. The WIM sensor is formed as an elongated profile along a longitudinal axis and defines a space therein. A force sensor configured to generate a force sensor signal corresponding to a dynamic ground reaction force when the wheel crosses the force sensor is arranged in the space. An electro-acoustic transducer is arranged in the space and configured to measure sound waves and accordingly generate a transducer signal.

Abstract: The invention relates to an optical device (1) (e.g. for enhancing the resolution of an image), comprising: a transparent plate member (55) configured for refracting a light beam (L) passing through the plate member (55), which light beam (L) projects an image comprised of rows and columns of pixels (40), and a carrier (30) to which said transparent plate member (55) is rigidly mounted, wherein the carrier (30) is configured to be moved between a first and a second state, whereby said projected image (30) is shifted by a fraction (?P) of a pixel, particularly by a half of a pixel, along a first direction (x). According to the invention, the carrier (30) is configured to be multistable (e.g. bistable or tristable), wherein said first and said second state are stable states of the multistable (e.g.

Abstract: The invention relates to an optical device for reducing speckle noise of laser light having a first optical element extending along an extension plane, and an actuator designed for moving the first optical element along the extension plane. The actuator is formed as a reluctance actuator that is designed to exert a reluctance force on the first optical element to move the first optical element along the extension plane.
