Abstract: To enable analysis of the performance of a customer contact center handling interactions across multiple types of communication channels, a system is provided that collects and analyzes data across the multiple channels and allows a user, such as an analyst, to analyze customer journeys that comprise multiple interactions, or contacts, across multiple communication channel types. That analysis can be used to identify journeys with similar, perhaps problematic, characteristics and provide the analyst user with the ability to examine the collected data for each identified journey individually. Once a journey is selected, the system displays the collected data in a coordinated display of journey timeline, text history, and sequence of automatically detected significant events.

Abstract: A muffler for an exhaust system of a vehicle comprises an outer housing in an interior of which a Helmholtz chamber is formed. A feed body has an opening fluidically connected to the Helmholtz chamber. At least two exhaust pipes extend at least in sections within the outer housing, are spaced apart from each other, and form a flow path for an exhaust gas through the outer housing. The exhaust pipes each have at least two exhaust pipe sections which are entirely spaced apart from each other by a gap in one flow direction of the exhaust gas. The feed body surrounds the exhaust pipes over an entire circumference in a region of the gaps and fluidically connects the exhaust pipes to the Helmholtz chamber.

Abstract: A clamping device is adjustable and capable of transmitting high torques, with little material and cost outlay. A clamping sleeve has an outer contour which can be adjusted, with an elastic change in shape, by radially adjustable rolling bodies disposed in the interior of the clamping sleeve. The outer contour has a nominal shape in an expanded state of the clamping sleeve.
