Abstract: Linear drive with a gear housing extending along a longitudinal axis, in which a spindle is rotatably mounted with a worm wheel connected to it in a rotationally fixed manner, a spindle nut running on the spindle, which is adjustable on the spindle between a retracted position and an extended position and which acts on a lifting tube. The spindle nut is arranged in the retracted position guide tube and retracted in the region of a rear end of the guide tube, and thus the lifting tube is also retracted into the guide tube. The spindle nut is arranged at a front end of the guide tube in the extended position. An electric motor drives the screw, which extends along a transverse axis extending transversely to the longitudinal axis, wherein the electric motor is accommodated in a motor housing which is connected to the gear housing. Furthermore, a control system is arranged in a control housing.

Abstract: A linear drive having a transmission housing and an electric motor which is accommodated in the transmission housing and drives a shaft with a worm. The shaft meshes with a worm gear which is non-rotatably connectable to a clutch to a spindle holder non-rotatably connected to a spindle. The clutch is biased by a spring and is adjustable by a clutch actuation. The clutch actuation includes a slide element which bears against the clutch and which is arranged non-rotatably but axially displaceably. A rotary element which is axially fixed but rotatable about an axis of rotation engages the slide element at an outside that faces away from the clutch. Run-on bevels of complementary configuration are provided between the slide element and the rotary element. The rotary element is actuable by a pulling element, and the slide element is axially displaceably in relation to the rotary element.

Abstract: An imprint template configured to imprint an imprintable medium by an imprint lithography process is disclosed, the imprint template having a pattern with a pattern density corresponding to a volume of imprintable medium used to substantially fill pattern features per unit area of a contact face of the imprint template, wherein adjacent regions of the pattern on the imprint template contact face, each of which will provide different functionality once imprinted onto a substrate, have substantially the same pattern density, have differences in pattern density which are minimized, or differences in pattern density which are maintained below a maximum.

Abstract: A visual prosthesis implant (1) is provided which comprises an SIMD-based processor array (6) adapted for receiving image signals from an image sensor (5) and outputting processed signals, and a bio-compatible electrode implant (7) receiving the processed signals and adapted for coupling to neurons. Using the SIMD-based processor array (6) provides high performance at small power dissipation and small chip area such that a fully implantable is visual prosthesis is achieved.

Abstract: Method for manufacturing a crossbar circuit on a substrate (1), the crossbar circuit comprising a first grid of first wires (10) and a second grid of second wires (17), the first wires extending in a first direction, the second wires extending in a second direction, the first direction and the second direction being arranged relative to each other to form a single two-dimensional wire grid, each first wire being separated from each second wire by an intermediate layer (14) located at a location where the first and second wires overlap; the method comprising: depositing an unprintable layer (2) on the substrate, imprinting a two-dimensional grid mask (5) into the unprintable layer by a mould (3); directionally depositing a first material (8) in the first direction on the grid mask; and directionally depositing a second material (15) in the second direction on the grid mask, the grid mask acting as a shadow mask during the directional deposition of the first and second material.
