摘要： An electronic pacemaker for implantation in a body of a living being including an electrode portion that is configured to be attached to a body portion; an electronics assembly connected with the electrode portion, configured to generate a voltage impulse emitted via the electrode portion to the body portion; a rechargeable accumulator to supply the electronics assembly with electrical energy; and a charging impulse generation portion electrically connected to the accumulator, configured to emit a charging impulse to the accumulator for the recharging of the accumulator. The charging impulse generation portion includes a magnetization portion with oriented magnetic domains which can be contactlessly influenced by an changing magnetic field so that, when a certain field strength is reached, a remagnetization wave, caused by the continuously reversing magnetic domains, occurs in the magnetization portion which runs across the magnetization portion and leads to the generation of the charging impulse.

摘要： The invention relates to a charging device (100, 200, 300) for contactlessly charging an energy storage of an implant (I) implanted in a body of a living being, comprising:



at least one self-supporting coil (110, 210) extending along a coil axis and configured to generate alternating magnetic field; wherein
during intended use of the charging device (100, 200, 300), the body is arranged relative to the coil (110, 210) so that the alternating magnetic field extending in the area inside the coil along the coil axis penetrates the body for charging the energy storage.

摘要： The invention relates to a magnetic linear or rotary encoder (1) for monitoring the motion of a body, comprising: an exciting unit (8), which reproduces said motion and has at least one pair of primary permanent magnets (16, 17), which are arranged opposite one another and are magnetically connected to one another by means of a ferromagnetic yoke body (9) and form a measurement field space therebetween; a fine-resolution sensor unit (29; 29′), which is used to determine a fine position value, is arranged in a stationary manner and has a plurality of magnetic field sensors (25, 26, 27, 28); and processing electronics, which evaluate the signals of the fine-resolution sensor unit and have a data memory. Said magnetic linear or rotary encoder is characterised in that a ferromagnetic deflecting body (18) is provided, which deflects at least some of the magnetic field lines of the magnetic field produced by the primary permanent magnets in a direction permanent to the magnetisation vector of the primary permanent magnets, that the fine-resolution sensor unit is designed and arranged in such a way that the individual magnetic field sensors of the fine-resolution sensor unit are penetrated by the magnetic field lines deflected by the deflecting body by means of a perpendicular component, that at least the yoke body is made of a thermally treated, ferromagnetic material, and that the fine-resolution sensor unit does not contain a ferromagnetic component.
