Abstract: An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.

Abstract: An automatic dispensing device for dispensing a volatile substance, the device comprising: a fan configured to generate airflow and dispense the volatile substance from the device; a drive apparatus having at least one electromagnetic coil connectable to a drive circuit; wherein the fan comprises at least one magnet located along an arc of the fan and the electromagnetic coil is configured to attract or repel the at least one magnet; wherein the drive circuit is configured to switch the current direction in the electromagnetic coil to sequentially attract and then repel the at least one magnet as the fan rotates.
