Abstract: A fine-adjustable charged particle lens comprises a magnetic circuit assembly including permanent magnets and a yoke body, surrounding a beam passage extending along the longitudinal axis. The permanent magnet is arranged between an inner yoke component and an outer yoke component so as to form a magnetic circuit having at least two gaps, generating a magnetic field reaching inwards into the beam passage, into which a sleeve insert having electrostatic electrodes can be inserted, which may also generate an electric field spatially overlapping said magnetic field. In order to modify the magnetic flux and thus the magnetic field in the gaps, a thermal control element located in the yoke body introduces or extracts heat to or from components of the of the magnetic circuit assembly so as to thermally control or modulate the magnetic behavior of said components.

Abstract: A fine-adjustable charged particle lens comprises a magnetic circuit assembly including permanent magnets, a yoke body, and a shunting device comprising a shunting component, and this assembly surrounds a beam passage extending along the longitudinal axis (cx). The shunting device is placed in the yoke body besides the permanent magnets and may be composed of several sector components, comprising different high magnetically permeable materials. The permanent magnet and the yoke body form a magnetic circuit having at least two gaps, in order to generate a magnetic field reaching inwards into the beam passage, into which a sleeve insert having electrostatic electrodes can be inserted, which may also generate an electric field spatially overlapping said magnetic field. The shunting device partially bypasses the magnetic flux of said circuit assembly and thus reduces the magnetic field to a desired value.

Abstract: An actuatable prosthesis device, comprising at least one drive, an electronic data processing device, and at least one sensor assembly for arranging on a body part of a prosthesis wearer. The at least one sensor assembly is designed to detect body signal patterns, and the electronic data processing device is designed to actuate the at least one drive on the basis of a detected body signal pattern such that the prosthesis devicecarries out a prosthesis movement assigned to the body signal pattern wherein at least two sets of body signal patterns and prosthesis movements assigned to each body signal pattern are stored on the electronic data processing device, and at least one trigger signal which switches over between the sets is assigned to the sets.
