Abstract: A method for controlling a lift installation having a plurality of cabins that can each stop at a number of floors may involve assigning calls placed outside the cabins to the cabins by way of a lift controller based on at least one assignment criterion. The method may involve considering a current traffic situation of the lift installation during the assignment. The method may further involve generating and considering a forecast of a future traffic situation of the lift installation during the assignment. The forecast may account for personal information of at least one of a person who is in a predetermined environment of the lift installation, a person who is in a section of the lift installation, a person who enters a predetermined environment of the lift installation, or a person who leaves a predetermined environment of the lift installation.

Abstract: A wine dispenser is disclosed that protects unpoured wine from oxidation due to exposure to air within the dispenser. The dispenser includes a dispenser body having a weighted piston disposed within, the weighted piston being configured to move toward the dispensing end of the dispenser body when the dispenser is tilted downward, causing wine to be dispensed via a dispensing assembly. The dispensing assembly includes a lid having a wine flow channel that provides a path for wine to flow out of the dispenser body, and a unidirectional flow valve that is biased in a closed air-tight state to prevent air from entering the dispenser body via the wine flow channel, unless the unidirectional flow valve is forced into an open state, thereby allowing wine to flow out from the dispenser body via the wine flow channel, and then out of the dispenser via a pouring neck.

Abstract: A wine dispenser is disclosed that preserves wine by reducing oxidation when partially filled with wine. The dispenser includes: a bottle body having a uniform cross section; a piston disposed within the bottle body for pushing the wine therethrough; a drive member capable of pushing the piston along the bottle body; and a dispensing assembly attached to the dispensing end. The dispensing assembly includes: a shoulder having a wine flow channel, the wine being able to flow out only via the wine flow channel; a neck in sealable and rotatable relationship with the shoulder, the neck having a pouring end and a flow regulation end, the flow regulation end having at least one opening that can be rotated so as to permit wine to flow in from the wine flow channel, through the at least one opening, and out through the pouring end, when pressure is applied to the piston.

Abstract: A control system for an elevator system may comprise elevator cars and an elevator control for assigning elevator cars to destination calls. In a first mode of operation, the elevator control may be adapted to determine and assign an elevator car to transport a passenger based on at least one elevator car determination criterion. The elevator control may wait to provide information identifying the elevator car assigned to the passenger until the assigned elevator car approaches or arrives at a floor on which the passenger is located. Waiting to provide such information permits the elevator control to modify which elevator car ultimately transports the passenger based on intervening factors such as a door being held on an elevator car that was initially assigned to transport the passenger. In a second mode of operation, the passenger may be provided with the information that identifies the assigned elevator car immediately after the destination call is placed.

Abstract: A method operates an x-ray system for examining an object. In order to optimize the operation of an x-ray system, in particular the dose regulation and/or the image processing, the following method steps are performed. Radiation is passed through the object to be examined and a number of fluoroscopic images of the object are generated. A relevant image region of a fluoroscopic image is selected by a user of the x-ray system. An image-based dose regulation of the radiation dose used for passing radiation through the object is carried out using the selected image region and/or image processing is carried out using the selected image region.

An asymmetry between the first branch and the second branch depends on the input signal. A value indicative of the input signal is determined based on received output signals of a plurality of readout events.

Abstract: An electric fan has a drive motor having a fan rotor, an apparatus for generating a rotation speed signal (n_i), an apparatus for generating a power level signal (P_i) that represents power consumed; a first regulator (n_RGL) for regulating the rotation speed signal (n_i) to a predefined target value (n_s); a second regulator (P_RGL) for regulating the power level signal (P_i) to a predefined power level signal target value (P_s) that corresponds to a predefined minimum consumed power level (P_min), where the first regulator (n_RGL) and the second regulator (P_RGL) apply at least one control output signal (SW) to the drive motor and interact in such a way that, during operation, the at least one control value (SW) in a first state is determined by the first regulator (n_RGL), and in a second state is determined by the second regulator (n_RGL).

Abstract: A rivet stud has a rivet body with an elongated shank, a flange, and an axial bore in which is located a tension mandrel, which has a mandrel shank with a drawing end projecting out of a head end of the rivet body that is separable from the mandrel shank at a predetermined breaking point and which has a mandrel head that is supported on a foot end of the rivet body.
