A position sensor for determining position information related to the position of a selected component of the flap assembly is associated with the flap assembly and movement commands for the drive arrangement are generated by the control arrangement based on the position information, to close the flap to an upright closed position during a motorized closing process and to open the flap to a horizontal open position during a motorized opening process. The pivoted open flap may be occupied by an object or a person. The position sensor detects the object or person based on at least one occupancy criterion and an occupancy reaction is triggered depending on the detected occupancy state.

Abstract: An objective system of a medical scope including an optical filter is disclosed. The optical filter includes a light incident side and a light exit side, a central region around an optical axis, and a peripheral region and is designed as an aperture with a single optical axis for white light and fluorescence light. The optical filter includes a first transmission zone for a transmittance of a first wavelength band and a second transmission zone for a transmittance of a second wavelength band at least partially different from the first wavelength band. At least one of the two transmission zones includes a filter coating. As a result, when both white light and fluorescence light pass the optical filter, a light beam cone of the fluorescence light has a larger diameter than a light beam cone of white light or vice versa. The invention also discloses a related endoscope.

Abstract: In a method for operating an energy converter that couples a first supply network to a second supply network by converting electrical energy via a switch element, the switch element is operated in a switching operation and a supply-network current for one of the supply networks is adjusted depending on a comparison of the supply-network current with a reference current. In a first operating mode for the switching operation, an electrical voltage of one of the supply networks is set by a PWM method on the basis of the comparison, and a second operating mode is provided, in which the switch element is switched when, during the comparison, a difference between the supply-network current and the reference current is greater than a first predefined relative switching value and/or is smaller than a second predefined relative switching value, wherein the first and second operating modes are alternated during the operation.

Abstract: In order to compensate for a drop in sensitivity at high rotational speeds, an acceleration sensor having an inductive measuring head (T) which cooperates with a moving Ferraris disk (F) essentially over a main magnetic field and which supplies an acceleration-dependent variable (Vdet; V?) is expanded by an additional DC magnetic field excitation circuit (13, 14, IK, RK) with a means for driving the latter with the effect that the additional DC magnetic field acts in a compensating fashion on an eddy-current DC field, starting from a relatively high rotational speed (?) of the Ferraris disk (F). This can be performed by amplifying the main magnetic field or by reducing the eddy-current DC field. A control signal (V?), dependent on rotational speed, which both can be generated outside the sensor via a characteristic curve, and can be derived in the form of a control loop from the sensor signal (V?), serves as a drive.
