Abstract: A magnetic cogging parallel-elastic actuator (100) can include a motor (102) having an output shaft (104). The actuator (100) can further include a cogging-torque element (106). The cogging-torque element (106) can include a stator that is stationary relative to the motor (102) and a rotor that is rotatable relative to the stator and comprises an output shaft (104). A plurality of stator magnet elements can be disposed radially about the stator and a plurality of rotor magnet elements can be radially positioned about the rotor. The output shaft (108) of the rotor of the cogging-torque element (106) can be connected in parallel with the output shaft (104) of the motor (102) such that an output torque of the actuator (100) is a sum of a torque of the cogging-torque element (106) and a torque of the motor (102).

Abstract: A magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets fixed in relation to said body and a control unit supplying the current for the electromagnets. The electromagnets have soft magnetic cores and the current supplied by the control unit to each of the electromagnets is adapted to operate the electromagnetic coils of each of the electromagnets in their core's linear regions being delimited by the value of the flux density of each electromagnet being in an interval between the negative and positive saturation value of each electromagnet, the lower representation showing the deviation due to the use of soft magnetic cores in all electromagnets.

Abstract: A sensor for intraocular measurements moveable within at least one of an vitreous humor of an eye, an aqueous humor of an eye and an intraocular replacement medium. The sensor includes a magnetic body susceptible to magnetic fields and at least one sensor film.
