Abstract

A mobile alarm apparatus includes a detection apparatus for detecting positional changes of the alarm apparatus; an output apparatus for the output of alarm signals; and a control apparatus for controlling the output apparatus in dependence on detected positional changes. The control apparatus is operable in a monitoring mode and in an alarm mode. In the monitoring mode, the control apparatus is configured to control the output apparatus to output a pre-alarm and to change into the alarm mode when a detected positional change is within a first range of significance. In the alarm mode, the control apparatus is configured to change into the monitoring mode when a predefined time period has elapsed since the last output of an alarm signal and otherwise, when a detected positional change is within a second range of significance, to control the output apparatus to output a main alarm different from the pre-alarm.

First claim

1 . A mobile alarm apparatus for releasable fastening to a movable object, comprising:
a detection apparatus that detects positional changes of the alarm apparatus; an output apparatus that outputs an alarm signals; and a control apparatus that controls the output apparatus in dependence on detected positional changes, the control apparatus is operable in a monitoring mode and in an alarm mode, wherein in the monitoring mode the control apparatus is configured:
to control the output apparatus to output a pre-alarm and to change into the alarm mode when a detected positional change is within a first range of significance; and
wherein in the alarm mode the control apparatus is configured:
to change into the monitoring mode when a predefined time period has elapsed since a last output of an alarm signal;
and otherwise to control the output apparatus to output a main alarm different from the pre-alarm when a detected positional change is within a second range of significance.

2 . The mobile alarm apparatus in accordance with claim 1 , wherein the main alarm has a different volume, pitch and/or modulation frequency than the pre-alarm.

3 . The mobile alarm apparatus in accordance with claim 1 , wherein the main alarm has a larger duration, volume, pitch and/or modulation frequency than the pre-alarm.

4 . The mobile alarm apparatus in accordance with claim 1 , wherein the detected positional change is considered to be within the first range of significance when a measured value corresponding to the detected positional change is larger than or no smaller than a minimal value of the first range of significance, and the detected positional change is considered to be within the second range of significance when a measured value corresponding to the detected positional change is larger than or no smaller than a minimal value of the second range of significance.

5 . The mobile alarm apparatus in accordance with claim 4 , wherein the measured value is an angular value.

6 . The mobile alarm apparatus in accordance with claim 4 , wherein the minimal value of the first range of significance is smaller than the minimal value of the second range of significance.

7 . The mobile alarm apparatus in accordance with claim 4 , wherein the first range of significance and the second range of significance mutually overlap.

8 . The mobile alarm apparatus in accordance with claim 5 , wherein the minimal value of the first range of significance amounts to at least 2° and to at most 10°; and/or wherein the minimal value of the second range of significance amounts to at least 12° and to at most 20°.

9 . The mobile alarm apparatus in accordance with claim 1 , wherein the detected positional change is considered to be within the first range of significance when a measured value corresponding to the detected positional change is larger than or no smaller than a minimal value of the first range of significance and is smaller than or no larger than a maximum value of the first range of significance, and/or the detected positional change is considered to be within the second range of significance when a measured value corresponding to the detected positional change is larger than or no smaller than a minimal value of the second range of significance and is smaller than or no larger than a maximum value of the second range of significance.

10 . The mobile alarm apparatus in accordance with claim 9 , wherein the maximum value of the first range of significance corresponds to the minimal value of the second range of significance.

11 . The mobile alarm apparatus in accordance with claim 1 , wherein the predefined time period after whose elapse the control apparatus changes from the alarm mode into the monitoring mode amounts to 3 seconds or to 5 seconds.

12 . The mobile alarm apparatus in accordance with claim 1 , wherein the predefined time period after whose elapse the control apparatus changes from the alarm mode into the monitoring mode is dependent on what kind of alarm signal was last output.

13 . The mobile alarm apparatus in accordance with claim 1 , wherein in the monitoring mode the control apparatus is furthermore configured:
to control the output apparatus to output the main alarm and to change into the alarm mode when a detected positional change is not within the first range of significance, but is within the second range of significance.

14 . The mobile alarm apparatus in accordance with claim 1 , wherein in the alarm mode the control apparatus is furthermore configured:
to control the output apparatus to output a pre-alarm when the predefined time period since the last output of an alarm signal has not yet elapsed and a detected positional change is within the first range of significance, but not within the second range of significance.

15 . The mobile alarm apparatus in accordance with claim 1 , wherein the control apparatus is configured to start the monitoring mode subsequent to an activation of the alarm apparatus or subsequent to an activation of the alarm apparatus after an elapse of a predefined waiting time.

16 . The mobile alarm apparatus in accordance with claim 15 , wherein the predefined waiting time is dependent on a charge state of an energy source of the alarm apparatus.

17 . The mobile alarm apparatus in accordance with claim 1 , wherein the alarm apparatus further comprises:
a closable fastener that fastens the alarm apparatus to the movable object; and wherein the control apparatus is configured to start the monitoring mode automatically subsequent to a closing of the closable fastener or subsequent to the closing of the closable fastener after an elapse of a predefined waiting time.

18 . The mobile alarm apparatus in accordance with claim 17 , wherein the predefined waiting time is dependent on a charge state of an energy source of the alarm apparatus.

19 . The mobile alarm apparatus in accordance with claim 1 , wherein the control apparatus is furthermore configured to control the output apparatus to output a start signal on the start of the monitoring mode.

20 . The mobile alarm apparatus in accordance with claim 1 , wherein the movable object is a two-wheeler or a tool.
