Wireless tracking and monitoring electronic seal
First Claim
1. An electronic seal, comprising:
- a security mechanism configured for attaching to a physical asset;
a battery fuel gauge configured to monitor a capacity of a battery of the electronic seal;
a navigation system configured to determine a location fix for the electronic seal according to a time interval;
a processor coupled to the battery fuel gauge and the navigation system, the processor configured to determine if the batter capacity detected by the battery fuel gauge is below a threshold value and to adjust the location fix time interval when the battery capacity is below the threshold value andthe processor having a security interface coupled to the security mechanism, the processor configured for detecting a security event associated with the electronic seal or the physical asset, and for generating a security status in response to the detecting.

Abstract
An electronic security seal (e-Seal) is disclosed. The e-Seal monitors security of shipments including intermodal containers, reports tampers in real-time, monitors environmental status of goods and reports exceptions in real-time, and reports the location of the shipment with high frequency. The security monitoring complies with the ISO 17712 standard, adding electronic real-time reporting of tamper time and location and LED tamper indication. The e-Seal can be manufactured and operated at low cost due to diagnostic and logistic features. The e-Seal supports low cost upgrades due to a modular architecture allowing a plug-in update of separate functions. The e-Seal allows flexible usage across supply chain tradelanes, due to highly programmable operation including over-the-air remote programming via wireless communications. The e-Seal provides low power operation to save battery usage and lower costs.
