Abstract: A method may include receiving a first transaction inserting a record into a database and a second transaction deleting the record from the database. A validity period for the record may be determined based on a first commit time at which the first transaction is committed and a second commit time at which the second transaction is committed. A current table and/or a history table of a system versioned table may be updated to include the record based on the validity period of the record. One or more temporal operations may be performed based on the system versioned table. For example, a time travel operation may be performed to retrieve, based on the system versioned table, one or more records that are valid at a given point in time. Related systems and computer program products are also provided.

Abstract: A device (219) includes a housing (301) and a link (320) displaceably arranged in the housing (301) and having an input port (323) configured to receive an input force (269) oriented along a first axis (91), a first output port (321) configured to provide a first output force (261) based on the input force (259, 269), and a second output port (322) configured to provide a second output force (262) based on the input force (259, 269). The link (320) is configured to move the first output port (321) from a start position (291) to a stop position along the first axis (91) by a first distance in response to receiving the input force (269) and to move the second output port (322) from the start position (291) to the stop position (294) along the first axis (91) by a second distance (422) in response to receiving the input force (259, 269). The first distance is smaller than the second distance.

Abstract: A method controls a working platform having at least one distance sensor assigned to a wheel of the working platform. A time of flight of a measuring beam, which represents a beam emitted obliquely onto a track of the working platform by the distance sensor, is determined. The time of flight determined in this manner is compared with a reference time of flight in order to determine a change in the inclination angle of the working platform. A control signal for controlling the working platform is output on the basis of the inclination angle change. As a result, a change in the gradient of a track in front of each wheel is individually determined before the particular wheel travels on the track section with the inclination change.

Abstract: A method for producing a three-dimensional object (2) by layer-by-layer application and selective solidification of a build-up material (13) comprises the steps: applying a layer of the build-up material (13) on a construction field by means of a coater (14) moving above the construction field, selectively solidifying the applied layer at points which correspond to a cross section of the object (2) to be produced, and repeating the steps of application and selective solidification until the object (2) is finished. In this case, firstly a support structure (30) is formed on a construction platform (9) and then the object (2) is formed on the support structure (30) by the above steps, wherein the support structure (30) has a weakened region (30b), which is arranged on average closer to the construction platform (9) than to the object (2) and which is more easily severable than the regions (30a) of the support structure adjacent in height.

Abstract: A wobble joint fitting for a vehicle seat has a first joint arm, which carries an internal gear and forms a first bearing surface, which are central to a main axis, and a second joint arm to which an eccentric gear is allocated, which comprises an externally toothed pinion and a second bearing surface. The pinion and the second bearing surface are central to an eccentric axis. An eccentric driving part is disposed in the area between the first bearing surface and the second bearing surface. Clamping parts, in a clamping state, displace the eccentric axis relative to the main axis. The eccentric driving part defines the eccentric. The rotary drive of the eccentric driving part causes a rotation of the pinion relative to the internal gear even without the clamping parts being present, wherein only play compensation is not obtained without the presence of the clamping parts.
