Abstract:
Timer apparatus (10) comprising a timer (11) and command means (12, 14, 15, 19) and alerting means (13) connected to the timer, in which at a starting time (tr) the timer (11) determines a first nominal alert interval (Tn) which starts at the starting time (tr) and which ends at a nominal alert time (tn) in a time window (T.sub.w), in the time window (T.sub.w) the timer (11) controls the alerting means (13) so that they deliver an alert signal until receipt of a reset signal at a reset time, and the command means then starts subsequent nominal alert intervals (Tn) with associated time windows (Tw) at a starting time in a present time window (T.sub.w), characterized in that the reset time in a window (T.sub.w) is made the starting time (tr) for a subsequent nominal alert interval (Tn), and the duration of a next window is made depended from a time difference between a starting time (tr) in a window and a nominal alert time (tn) of a preceding window.
