Abstract: A method for dynamically generating at least one contextual user interface element within a user interface and establishing a connection between a first computing device associated with a user of the user interface and a second computing device associated with a contact center agent includes analyzing, by a user interface display component executing on a first computing device, a uniform resource locator of a web page while a user views the web page on a second computing device. The user interface display component identifies a plurality of support topics, accesses profile data associated with the user, and determines whether the profile data identifies an existing travel reservation. The user interface display component generates a first subset of the plurality of support topics and modifies a user interface displayed by the web page to include a user interface element associated with a support topic in the first subset.

Abstract: A conveyor for medium distances has a track with at least two entry/exit points (1), by which cars (4-8) that can be run are run or moved continuously and rest snugly against one another as a footprint that is designed as a sector of a circle or a ring segment. The entry/exit points (1) are connected in two travel directions with one track that is usually designed from rails (2, 3), along which the cars (4-8) can be moved in an individually controlled manner by a drive. The running speed along the track is independent of that when moving through the entry/exit points (1). The conveyor therefore combines the advantages of continuously running conveyor belts with those of rapid transport tracks.

Abstract: A transport installation has at least one rail, on which transport carriages are able to be transported by at least one trolley, and on at least one side has a guide arrangement which stabilizes the state and position of the transport carriage above the rail. A drive unit with several runners is provided in the trolleys of the transport carriages, which drive unit is able to be swivelled about the axis of the rail with respect to the trolley. The rail bifurcates into two rail branches. In the region of the bifurcation, grooves can be formed on the upper surface of the rails and rail branches. The pivoting angle and angle coverage of the drive unit and depth of the grooves are greatly reduced.

Abstract: A transport system has at least one track, preferably hung on supports or hanging from cables, on which transport cars may travel, by at east one trolley. Several running wheels are provided in the trolley and the trolley may be actively rotated about the axis of the track relative to the transport car. Branchings are provided in the track, in which the track divides into two track branches. In the vicinity of the branching lies an intersection of the outer surfaces of the track branches, such that on each of the upper side and the lower side there are two grooves due to the intersection, which meet in the vicinity of the gusset, between the two track branches. Between the grooves, on both the upper and lower side, is a tapering web, the surfaces of which are part of the surface area of the track branches.

Abstract: A circuit configuration includes a symmetrically constructed sample and hold amplifier. A first switchable level shifter has an input in the form of a first signal input terminal for receiving a given signal, and an output being connected to the sample and hold amplifier for supplying a differential output signal. A second switchable level shifter has an input in the form of a second signal input terminal for receiving a signal complementary to the given signal, and an output being connected to the sample and hold amplifier for supplying a differential output signal. The input and output signals of each of the switchable level shifters having a different constant direct voltage difference as a function of the switching state of the level shifters.

Abstract: A sample and hold circuit configuration for differential signals with reduced holding capacity includes an amplifier in which the same current ratios prevail in the collector circuit and in the emitter circuit. The base currents are discharged through additional transistors and therefore the same currents flow and equal voltage ratios prevail in the collector and emitter resistors, and an additional diode is connected in each collector circuit.

Abstract: In a method and device for limiting the starting current of a DC converter, at least one buffer capacitor is initially charged through a load resistor. The current going through the load resistor is measured with a monitor. The monitor switches on a DC converter and bridges the load resistor once a switching threshold is reached. A predetermined minimum current is used as the switching threshold.
