Abstract
An alarm system may be provided and may include a miniature coin size tag attached to doors and windows. The tag has electronic 3 axial accelerometer with wireless notification system to user's smart phone.
Claims20
A tag that comprises a three axial accelerometer, a controller, a transmitter and an attachment member for attaching the tag to an object;
- wherein the three axial accelerometer is configured to monitor accelerations of the object along three axes and generate acceleration values;
- wherein the controller is configured trigger an alert in response to (a) acceleration values obtained at a certain period and (b) an outcome of an auto learning algorithm applied on, at least, historical acceleration values obtained during a learning period that started before the certain period;
- wherein the controller is configured to determine at least one jiggling value that represents differences between acceleration values that (a) are obtained during the certain period and (b) are associated with at least one axis of the three axes;
- wherein each jiggling value represent a maximal difference between acceleration values associated with a certain axis of the three axes.

A method, comprising:
- monitoring, by a three axial accelerometer of a tag that is attached to an object, accelerations of the object along three axes and generating acceleration values;
- determining, by a controller of the tag, at least one jiggling value that represents differences between acceleration values that (a) are obtained during the certain period and (b) are associated with at least one axis of the three axes;
- wherein each jiggling value represent a maximal difference between acceleration values associated with a certain axis of the three axes;
- and
- triggering, by the controller of the tag, an alert in response to (a) acceleration values obtained at a certain period and (b) an outcome of an auto learning algorithm applied on, at least, historical acceleration values obtained during a learning period that started before the certain period.
