Abstract: The present disclosure relates to compact hearing aids, components thereof, and support systems therefor, as well as methods of insertion and removal thereof. The compact hearing aids generally include a sensor, such as a microphone, an actuation mass, an energy source for providing power to the compact hearing aid, a processor, and an actuator enclosed in a housing that is designed to be inserted through the tympanic membrane during a minimally-invasive outpatient procedure.

A processor then modifies the electrical signals and provides the electrical signals to the actuator. The actuator converts the electrical signals into mechanical motion, which actuates the actuation mass to modulate the velocity or the position of the tympanic membrane.

Abstract: A table device for an interior of a vehicle includes a table element that is positionable from a non-use position into a use position. The table element, secured to a pivot arm in the non-use position, forms a trim element of a center console of the vehicle. The pivot arm is secured to a frame element and the frame element is guided by a guide element through a predefined movement path. The frame element is liftable by a first drive unit through the predefined movement path such that the table element pivots out in part, through a predefined angle, from a housing formed by the center console. The table element is liftable by a second drive unit into the use position.
