摘要： In order to ensure particularly good protection of individuals in an electromagnetic transport system, a safety area is provided in a transport area. Furthermore, a safety function is provided which, in accordance with a predetermined safety requirement level, ensures that the transport unit reaches the safety area at a speed less than or equal to a safety speed and/or with a transport unit force less than or equal to a safety force and/or a transport unit energy less than or equal to a safety energy, or prevents the transport unit from reaching the safety area.

摘要： In order to specify a flexible transport arrangement for a long stator linear motor which can be used more flexibly for the transport of products, a transport arrangement includes a transport unit and a product carrier. The transport unit and the product carrier each have at least one guide element arranged in the direction of movement and transport unit has drive magnets arranged in a direction of movement for driving the transport unit. The product carrier has no drive and is couplable to the transport unit via a coupling point and is drivable by the transport unit via the coupling point.

摘要： Method for time synchronization in a network comprising masters and at least one slave. The slave receives synchronization messages from the masters via the network for time synchronization of a first clock and a second clock of the slave. A first master sends a first synchronization message having a first time stamp to the slave for time synchronization of the first clock. The slave calculates a clock rate and a time difference between the first clock and the first master and aligns the first clock with a synchronized time. A second master sends a second synchronization message having a second time stamp to the slave for the time synchronization of the second clock. The clock rate of the second clock is set to the first clock rate. A time difference between the second clock and the second master is calculated and the second clock is aligned with the synchronized time.

摘要： For a kinematic modelled in a kinematics coordinate system by hingedly interconnected single axles, a method calculates a braking region possibly covered by at least one of the single axles connected to an origin of the kinematics coordinate system and at least one of the single axles moving relative to the origin. In the event of a braking process, for a point that is coupled to a single axle, at least one virtual end position of the point is determined from an initial position of the point, a vectorial speed of at least one single axle, and a minimum deceleration of at least one single axle. The braking region of the point is determined using an envelope of the initial position and the at least one virtual end position, the extent of the envelope being calculated from the initial position and the at least one virtual end position.

摘要： For an easily implementable method for position determination using an inductive position sensor with increased precision of the position information, the position sensor generates a measurement signal from which a frequency functional dependent on the excitation frequency is formed, which represents a measure of the noise signal and the excitation frequency of the excitation signal is changed so that the frequency functional is minimized or maximized and the excitation frequency that minimizes or maximizes the frequency functional is used for the excitation signal.

摘要： A a more efficient power supply system comprises a rectifier, a low voltage inverter, and a low voltage actuator, the rectifier converting a mains AC voltage into a low input DC voltage, the low voltage inverter connected to the rectifier and converting the low input DC voltage into a low supply AC voltage, and the low voltage inverter connected to the low voltage actuator to supply the low voltage actuator with power via the low supply AC voltage. A DC-DC converter connected to the rectifier converts the low input DC voltage into an extra-low DC voltage. An extra-low voltage inverter connected to the DC-DC converter converts the extra-low DC voltage into an extra-low supply AC voltage. The extra-low voltage inverter connected to an extra-low voltage actuator supplies the extra-low voltage actuator with power via the extra-low supply AC voltage.

摘要： Apparatus for the detection of print marks with a sensor arrangement which has at least one contrast sensor, which for generation of a cyclical sensor signal is disposed above the area of printed material containing the print mark which is passed below the contrast sensor, said apparatus also having a signal conditioning unit. The signal conditioning unit has at least one filter unit with a first filter for determination of the first derivation of the sensor signal, and on the basis of an evaluation of at least the first derivation of the sensor signal the filter unit generates at least one output value which is representative of print marks.

摘要： For a long stator linear motor comprising a switch and secure guidance of the transport vehicles in the direction of movement along the transport track, it is provided that the transport vehicle (Tn) is force-guided, at least in sections, in the direction of movement (x) outside the switch (W), and at least one one-sided track section (2d) is provided on the transport track (2), along which a vehicle guide element (7) only on one side of the transport track (2) interacts with the track guide element (6) on the assigned side of the transport track (2) for the mechanical forced guidance in the direction of movement (x), and the forced guidance in the direction of movement (x) in the transverse direction (y) is canceled in the region of the switch (W).
