Abstract: This patent discloses inventive methods and systems for automatically monitoring an electronic information stream for the occurrence of preconfigured trigger condition, such as the presence of keywords, images, and other identifiable stream content. Upon recognition of the preconfigured trigger condition, the inventive methods and systems automatically make a donation, send a counter-statement, or take some other preconfigured advocacy action related to the stream and trigger condition.

Abstract: The method according to the invention for riveting, or self-piercing, by means of a riveting or self-piercing device (8), having a male die (3) guided by a pick-up device (4), both of which in each case can be moved towards a female die (5) and/or a workpiece (6), wherein the female die (5) and riveting or self-piercing device (8) will be connected to one another via a counterforce structure (9). The relative movement between the pick-up device (4) and the counterforce structure (9) is measured by a first sensor (1), and the relative movement between counterforce structure (9) and male die (3) is measured by a second sensor (2). The depth of the riveting or piercing is adjusted with the aid of the two measured values.
