METHOD AND APPARATUS FOR DISABLING ACTIVE MODE OPERATION OF A DATA TAG DEVICE
First Claim
Patent Images
1. A method of triggering self-expiration of a data tag device, comprising:
- operating the data tag device in an active mode wherein the data tag device occasionally transmits a beacon and provides access to tag data;
detecting an occurrence of an expiration event while operating in the active mode; and
disabling a power source of the data tag device upon detecting the expiration, event thereby preventing subsequent operation in the active mode.

Abstract
The present invention discloses a data tag device (100) which initially operates in an active mode where the tag occasionally transmits an unsolicited beacon (412). While operating, an expiration event occurs (512, 514) which causes the tag to disable a battery (110), preventing subsequent operation in an active mode, but may continue operating in a passive mode.

12. A data tag device, comprising:
-
tag circuitry including; a machine readable memory having tag data stored therein; a communication interface configured to facilitate communication of the tag data; a controller operably coupled to the communication interface and the machine readable memory; a battery operably coupled to the tag circuitry and configured to provide power to the tag circuitry when the data tag device is operated in an active mode, wherein in the active mode the data tag device occasionally transmits a beacon via the communication interface, the beacon including the tag data; and a battery disabling circuit coupled to the battery and responsive to an expiration event, the battery disabling circuit configured to disable the battery upon occurrence of the expiration event thereby changing the battery from an enabled state to a disabled state; wherein the controller is configured to operate in the active mode while the battery is in the enabled state, and ceases operation in the active mode when the battery is in the disabled state. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer program product having machine readable code stored thereon, the machine readable code causing a data tag device to:
-
operate the data tag device in an active mode wherein the data tag device occasionally transmits a beacon and provides access to tag data; detect an occurrence of an expiration event while operating the data tag device in the active mode; and disable a power source of the data tag device upon detecting the expiration, event thereby preventing subsequent operation of the data tag device in the active mode. - View Dependent Claims (20)
