Abstract: The invention relates to an activation of temperature time monitors (1), particularly for perishable products, such as medications, vaccines, stored blood, or food products, wherein the monitor (1) contains at least one electrical circuit (4-6), which is mechanically activateable/changeable, characterized in that the monitor (1) is activatable by means of an irreversible mechanical interruption of an electrically conductive connection (8) of the at least one electrical circuit (4-6), or that the monitor (10) is activatable by means of an irreversible mechanical removal of an electrically conductive area (15) of the at least one electrical circuit (16, 17). The invention is based on the object of improving an activation of temperature time monitors in such a way what it is particularly cost effective and reliable, and that an automated activation is possible.

Abstract: A current source circuit degeneratively feeds back a control signal to a current mirror circuit via a single stage amplifier in order to reduce instabilities resulting from use of more than one stage.
