Abstract

A system includes at least three accelerometers disposed in different locations of an area to capture respective vibration data corresponding to an event and a processing system to receive the vibration data from each accelerometer and generate a notification based on the event and a location of the event identified from the vibration data.

Claims

1. A system comprising:

at least three accelerometers disposed in different locations of an area to capture respective vibration data corresponding to an event; and

a processing system to receive the vibration data from each accelerometer and generate a notification based on the event and on a location of the event identified from the vibration data.

2. The system of claim 1 wherein the processing system is to generate the notification in response to comparing the event and the location to a set of patterns and locations captured by the accelerometers prior to the event.

3. The system of claim 1 wherein the processing system is to include an indication of the location in the notification.

4. The system of claim 1 wherein the processing system is to associate the event with a device at the location.

5. The system of claim 1 wherein the processing system is to store the event in an event log.

6. The system of claim 1 wherein the processing system is to identify the location of the event using triangulation.

7. The system of claim 1 wherein the accelerometers each include a proof mass with a first electrode array suspended above a second electrode array disposed on a wafer.

8. The system of claim 1 wherein the accelerometers each include three-phase sensing and actuation.

9. The system of claim 1 wherein the accelerometers each detect changes in capacitances between a first electrode arrays disposed on a proof mass and a second electrode array disposed on a wafer.

10. A method performed by a processing system, the method comprising:

receiving current vibration data corresponding to an event from at least three accelerometers disposed in different locations of an area;

identifying the event and a location of the event by comparing the current vibration data to previous vibration data captured prior to the event; and

providing a notification based on the comparison.

11. The method of claim 10 further comprising:

including an indication of the location in the notification

12. The method of claim 10 further comprising:

associating the event with a device at the location.

13. The method of claim 10 further comprising:

identifying the location by triangulating the vibration data.

14. A computer-readable storage medium storing instructions that, when executed by a processing system, perform a method comprising:

receiving first vibration data captured by at least three accelerometers disposed in different locations of an area during a first event; and

storing a first notification corresponding to a first device in the area based on the first event and a first location of the first event identified from the first vibration data.

15. The computer-readable storage medium of claim 14, the method further comprising:

receiving second vibration data captured by the at least three accelerometers during a second event; and

storing a second notification corresponding to a second device in the area based on the second event and a second location of the second event identified from the second vibration data, the second location differing from the first location and the first device differing from the second device.
