Abstract

An activity based monitoring system is disclosed, the activity based monitoring system being configured to monitor a plurality of badges associated with a plurality of assets within a healthcare facility.

Claims

1. A method for monitoring an asset to determine if the asset has been dropped or has fallen, the method comprising the steps of:

providing a badge adapted to be coupled to the asset, the badge having an accelerometer configured to monitor a vertical acceleration of the asset and a transmitter;

monitoring the vertical component of the acceleration of the badge;

transmitting information regarding the vertical acceleration of the badge;

determining if the vertical acceleration of the badge has exceeded a threshold value;

identifying the asset as having been dropped or as having fallen based on the vertical acceleration exceeding the threshold value.

2. The method of claim 1, wherein the step of determining if the vertical acceleration of the badge has exceeded a threshold value is performed by a processor remote from the badge.

3. The method of claim 1, wherein the step of determining if the vertical acceleration of the badge has exceeded a threshold value is performed by a processor of the badge.

4. The method of claim 1, wherein the vertical acceleration component is used to determine a speed associated with the asset.

5. The method of claim 1, further comprising the step of initiating an alarm based on a determination that the asset has fallen or has been dropped.

6. The method of claim 1, further comprising the step of providing an indication to a caregiver associated with the asset that the asset has fallen or has been dropped.

7. The method of claim 1, further comprising the step of flagging the asset as requiring recertification based on a determination that the asset has fallen or been dropped.

8. A system for monitoring an asset to determine if the asset has been dropped or has fallen, the system comprising:

a badge adapted to be coupled to the asset, the badge having an accelerometer configured to sense a vertical acceleration of the asset and a transmitter; and

a processor operable to execute software to monitor the vertical component of the acceleration of the badge which is transmitted from the badge, to determine if the vertical acceleration of the badge has exceeded a threshold value, and to identify the asset as having been dropped or as having fallen based on the vertical acceleration exceeding a threshold value.

9. The system of claim 8, wherein the processor is located remotely from the badge.

10. The system of claim 8, wherein the processor is carried by the badge.

11. The system of claim 8, wherein the vertical acceleration component is used to determine a speed associated with the asset.

12. The system of claim 8, wherein the processor is operable to activate an alarm based on a determination that the asset has fallen or has been dropped.

13. The system of claim 8, wherein the processor is operable to initiate a notification to a caregiver associated with the asset that the asset has fallen or has been dropped.

14. The system of claim 8, wherein the processor is operable to flag the asset as requiring recertification based on a determination that the asset has fallen or been dropped.
