Abstract

A sensor package is disclosed that includes a compass and/or an accelerometer. The compass may be activated by a microcontroller in response to an indication of movement detected by an accelerometer. The compass's data may be utilized to determine an orientation for the object such as a door on which the sensor package is situated. The orientation data may indicate that the door is ajar and/or that a second magnetic field is present, suggesting tampering. A notice may be dispatched to a controller for the home security system, a client device, a remote system, etc.

First claim

1 . A computer-implemented method, comprising:
receiving an indication of movement from an accelerometer associated with a sensor package further comprising a compass, the sensor package associated with an object having an orientation; sending an activation signal to the compass; receiving an orientation signal from the compass; and determining a change in the orientation of the object based at least upon the orientation signal from the compass.

2 . The method of claim 1 , wherein the object is selected from the group consisting of: a door, a garage door, a refrigerator door, a cabinet door.

3 . The method of claim 1 , wherein the object has a first surface and a second surface and wherein the accelerometer is situated on the first surface and the compass is situated on the second surface.

4 . The method of claim 3 , wherein the first surface is the same as the second surface.

5 . The method of claim 4 , wherein the accelerometer and compass are integrated into a single sensor package.

6 . The method of claim 1 , further comprising generating a notice in response to the change in the orientation of the object.

7 . The method of claim 6 , wherein the notice is selected form the group consisting of: a door open alert, a door close alert, an alarm, and a reset alert.

8 . The method of claim 6 , further comprising receiving, from a client device associated with an authorized occupant, a reset signal in response to the notice.

9 . The method of claim 6 , further comprising:
authenticating a user; and receiving from the authenticating user a reset signal in response to the notice.

10 . The method of claim 1 , further comprising:
generating a security breach message; and sending the security breach message to a third party, wherein the notice indicates a security breach.

11 . The method of claim 10 , wherein the security breach message includes at least one from the group of: an address, a security status, an authorized occupancy status, a telephone number, an image, and a video.

12 . The method of claim 1 , further comprising receiving, by the sensor package, power from a common power source.

13 . A computer-implemented method, comprising:
receiving input from an accelerometer; receiving input from a compass; wherein the accelerometer and the compass are associated with a given object; comparing the accelerometer input and the compass input to a motion profile for the given object; based on the comparison, determining that at least one of the accelerometer input and the compass input are inconsistent with the motion profile; and generating a notice in response to the determined inconsistency.

14 . The method of claim 13 , wherein the given object is a door attached to a wall with at least one hinge mechanism, wherein the inconsistency comprises accelerometer input that indicates a displacement greater than a maximum displacement of the door about the at least one hinge mechanism.

15 . The method of claim 13 , wherein the given object comprises a door, further comprising:
determining a first orientation change based on the accelerometer input; and determining a second orientation change based on the compass input, wherein the second orientation differs from the first orientation.

16 . The method of claim 15 , wherein the first orientation change is less than the second orientation change.

17 . The method of claim 13 , wherein the notice is selected from the group consisting of: a tamper alert, a door open alert, a door close alert, an alarm, and a reset alert.

18 . A system, comprising:
a computer-readable storage medium, configured to store data generated by a sensor package comprising at least one of an accelerometer and a compass, the sensor package associated with an object having an orientation; a processor communicatively coupled to the storage medium, the processor configured to:
receive an indication of movement from the accelerometer;
send an activation signal to the compass;
receive an orientation signal from the compass;
determine a change in the orientation of the object based at least upon the orientation signal from the compass.

19 . The system of claim 18 , wherein the object is selected from the group consisting of: a door, a garage door, a refrigerator door, a cabinet door.

20 . The system of claim 18 , wherein the object has a first surface and a second surface and wherein the accelerometer is situated on the first surface and the compass is situated on the second surface.

21 . The system of claim 20 , wherein the first surface is the same as the second surface.

22 . The system of claim 21 , wherein the accelerometer and compass are integrated into a single sensor package.

23 . The system of claim 18 , the processor further configured to generate a notice in response to the change in the orientation of the object.

24 . The system of claim 23 , wherein the notice is selected form the group consisting of: a door open alert, a door close alert, an alarm, and a reset alert.

25 . The system of claim 23 , the processor further configured to receive, from a client device associated with an authorized occupant, a reset signal in response to the notice.

26 . The system of claim 23 , the processor further configured to:
authenticate a user; and receive from the authenticating user a reset signal in response to the notice.

27 . The system of claim 18 , the processor further configured to:
generate a security breach message; and send the security breach message to a third party, wherein the notice indicates a security breach.

28 . The system of claim 27 , wherein the security breach message includes at least one from the group of: an address, a security status, an authorized occupancy status, a telephone number, an image, and a video.

29 . The system of claim 18 , wherein the sensor package is configured to receive power from a common power source.
