Abstract: A robot running axle for the displacement of a robot carriage has two parallel main supports, each of which is delimited on the outside by a metal profile in the form of a hollow profile or C-shaped profile, and each of which supports one guide rail. The main supports are connected to each other by a connection structure made of concrete, and the profiles of the main supports have an inner structure made of concrete. Alternatively, a polymer material or a metal foam can be used instead of concrete.

Abstract: Automation controller and method for operating the automation controller, wherein the automation controller includes Ethernet channels to which network interfaces can be assigned via a first register with a first register value and a second register with a second register value, where the assignments are made and these are examined for variances via test values.

Abstract: The present invention relates to a field effect transistor having heterostructure with a buffer layer or substrate. A channel is arranged on the buffer layer or on the substrate, and a capping layer is arranged on the channel. The channel consists of a piezopolar material and either the region around the boundary interface between the buffer layer or substrate and channel or the region around the boundary interface between the channel and capping layer is doped in a manner such that the piezocharges occurring at the respective boundary interface are compensated.

Abstract: The invention relates to a lighting unit that includes at least one light source and at least one rod-shaped optical waveguide following the light source, wherein each optical waveguide has at least one light emission surface. Each optical waveguide is flexible for this purpose. The present invention has developed a universally applicable, economical lighting unit for illuminating components.

Abstract: The invention relates to a heterostructure with a buffer layer or substrate, a channel arranged on the buffer layer or substrate and a capping layer arranged on the channel. Said channel is made from a piezopolar material and either the region around the boundary interface between the buffer layer or substrate and the channel, or the region around the boundary interface between the channel and the capping layer is doped in such a way that any piezo charging which occurs at the respective boundary interface is compensated.
