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 begins at the starting time (tr) and ends at a nominal alert time (tn), on the occurrence of the nominal alert time (tn) the timer (11) controls the alerting means (13) so that they deliver an alert signal, and on receipt of a starting signal from a starting command element (12) of the command means the timer (11) restarts with the current time (t) as the starting time (tr). On receipt of the starting signal the timer (11) determines a time window (Tw) which contains the nominal alert time (tn). The timer (11) controls the alerting means (13) so that they deliver the alert signal during the window (Tw).

Claims

1. 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_w), in the time window (T_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_w), characterized in that the reset time in a window (T_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.

2. Timer apparatus (10) according to claim 1, characterized in that for each reset time (tr (=t)) the timer (11) determines a difference time (tn−

t) of the nominal alert time (tn) minus the reset time (tr), the timer determines the sum (Tmtot) of the difference times of a number of successive windows (Tw) and, if the sum exceeds a predetermined threshold value (Tmmax), the timer (11) shortens a window part (Tm) preceding the nominal alert time (tn) of a subsequent window (Tw) by the time by which the threshold value has been exceeded (Tmmax−

(Tmtot+Tmf)).

3. Timer apparatus (10) according to claim 1, characterized in that for each reset time (tr (=t)) the timer (11) determines a difference time (t−

tn) of the reset time (tr) minus the nominal alert time (tn), the timer determines the sum (Tptot) of the difference times of a number of successive windows (Tw) and, if the sum exceeds a predetermined threshold value (Tpmax), the timer (11) shortens the window part (Tp) succeeding the nominal alert time (tn) of a subsequent window (Tw) by the time by which the threshold value has been exceeded (Tpmax−

(Tptot+Tpf)).

4. Timer apparatus (10) according to claim 2, characterized in that the threshold value (Tmmax;

Tpmax) is twelve hours.

5. Timer apparatus (10) according to claim 1, characterized in that if a last-determined window (Q) follows a predetermined number (nmax) of windows (Tw), and provided that the timer (11) receives a continuation signal from the command means (15), the timer (11) determines (75, 107) a subsequent window (R) at the end of a second nominal alert interval (74, 75;

106, 107).

6. Timer apparatus (10) according to claim 5, characterized in that the timer (11) makes the time window (R) at the end of the second nominal alert time interval twelve hours on each side of the nominal alert time (tn) of the window (R).

7. Timer apparatus (10) according to claim 1, characterized in that the form of the alert signal depends on the occurrence or absence of the starting time (tr) relative to one or more earlier determined windows (Tw).

8. Timer apparatus (10) according to claim 1, characterized in that during a window (Tw) the alert signal comprises an audible signal, the obtrusiveness of which increases with time (t).

9. Timer apparatus (10) according to claim 1, characterized in that during a window (Tw) the alert signal comprises an audible signal, and following receipt of a mute signal from a mute command element (14) of the command means the timer (11) suppresses the audible signal for a predetermined third interval (Ts).

10. Timer apparatus according to claim 1, characterized in that the command means have a command element in order to ensure that a subsequent nominal alert time (tn) is not made later than 24 hours from the last nominal alert time (tn).

11. Timer apparatus (10, 17) according to claim 1 characterized in that the timer apparatus (10) is integral with a medicine dispensing device (17) which comprises blocking means (18), in which after the starting time (tm) of a window (Tw) the timer (11) delivers a blocking removal signal to the blocking means (18), in order to remove a block on the dispensing of a medicine, and the medicine dispensing device (17) comprises a command element (12) which is connected to the timer (11), and which delivers the reset signal (tr) after a medicine has been dispensed.

12. Timer apparatus (10) according to claim 11, characterized in that the medicine dispensing device (17) comprises an enable command element (19) of the command means which is connected to the timer (11), and the timer (11) delivers the blocking removal signal only on receipt of an enabling signal from the enable command element (19).
