Abstract: A computer system having a graphical user interface that includes a display and a user interface selection device. The computer system includes a method of displaying and navigating calendar events. The method includes selecting an initial calendar time period for display; selecting initial time units; displaying a band looped around an axis from a point of view located on the axis wherein the band depicts the time units and the calendar events on the side facing the axis in chronological order; and using the user interface selection device to receive navigation commands moving the view point along the axis and/or rotating the band around the axis.

Abstract: The invention relates to devices and methods and arrays for detecting and avoiding stress cracks. One embodiment relates to a device for detecting a crack formation in a component as a result of hardening of the component under heat treatment, such as inductive hardening or flame hardening, for example, and/or resulting from straightening the component, comprising a sound sensor that can be coupled with the component to register structure-borne sound. The device is configured for the frequency-based and/or time-based evaluation of sound signals registered by the sound sensor during the hardening and/or during the straightening process.
