Time-sensitive article tracking device
DCFirst Claim
1. A method for determining whether an article tracking device is within a spatial zone, the method comprising the steps of:
- obtaining a current time and a current position of the device;
determining a spatial zone that corresponds to the current time;
determining whether the current position of the device is within the spatial zone; and
sending a request to a server for a subset of server database records in response to the determination of whether the current position of the device is within the spatial zone.

Abstract
An article tracking device that can be attached to or otherwise located with movable and non-moveable articles has a memory that stores a subset of spatial zones and corresponding time intervals during which the spatial zones are valid. The device is adapted to periodically read the current time and its current position from the position determination system and to determine whether a spatial zone corresponding to the current time exists. If a corresponding spatial zone exists, the device determines whether its current location is within the spatial zone and performs an action in response to this determination.

11. An article tracking device comprising:
-
a position determination receiver, the receiver for receiving signals that enable a determination of a current time and a current position of the device;
a memory communicatively coupled to the receiver, the memory for storing a plurality of database records, each database record comprising spatial zones and corresponding time intervals associated with the spatial zones; and
a processing module for obtaining the current time and the current position of the device from the receiver, determining a spatial zone that corresponds to the current time, determining whether the device is within the spatial zone, and sending a request to a server for a subset of database records held by the server in response to the determination of whether the device is within the spatial zone. - View Dependent Claims (12, 13, 14)

15. A server system for communicating with an article tracking device, the system comprising:
-
a spatial zones database for storing a plurality of records, each database record comprising time intervals and spatial zones associated with the time intervals; and
an action module for interfacing with the article tracking device, for receiving a request from the article tracking device for a subset of the records stored in the database, and for sending to the device at least the subset of the records stored in the database. - View Dependent Claims (16, 17, 18, 19, 20)
