This application: claims priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 60/528,334, filed on Dec. 9, 2003, entitled “Concept for Nested Visibility of Logistics Units, Including Handheld Nested Visibility,” by Stephen Lambright et al.; claims priority under 35 U.S.C. § 120 as a continuation-in-part of U.S. patent application Ser. No. 10/841,368, filed on May 6, 2004, entitled “Nested Visibility for a Container Hierarchy,” by Stephen Lambright et al., which claims priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 60/468,930, filed on May 7, 2003, entitled “Concepts for Smart Container,” by Stephen Lambright et al. and claims priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 60/468,929 filed on May 7, 2003, entitled “Concepts for Nested Visibility of Logistics Units,” by Stephen Lambright et al.; and is related to U.S. patent application Ser. No. ______ <attorney docket #21790-09682>, filed Dec. 9, 2004, entitled “Item-Level Visibility of Nested and Adjacent Containers,” by Stephen Lambright et al., the entire contents of each being herein incorporated by reference.
The present invention provides an integrated device for reading heterogeneous tag types. This allows disparate tag types, such as passive and active tags, to be read using a single device. A passive tag, as used herein, is any tag without a power source. An active tag, as used herein refers to a tag with a power source. In addition, the integrated device allows the device to establish the interrelationship between the heterogeneous tag types.
Thus, the present invention is advantageous over traditional readers that require separate readers for each tag type. Rather than using two separate devices, a single integrated reader may be used that is capable of reading both active and passive tags, at great savings of time, money, and equipment. The integrated reader device is configured to send and receive signals to and from both active and passive type identification devices.
The present invention also provides an integrated device for reading heterogeneous tag types. This allows disparate tag types, such as passive and active tags, to be read simultaneously using a single device. A passive tag, as used herein, is any tag without a power source. An active tag, as used herein refers to a tag with a power source.
The identification devices 220, 232, 236 although at different layers, are each capable of independent communicate with the integrated identification device 225. Thus, the identification devices 220, 232 need not daisy chain information up a ladder as the integrated identification device 225 can gather information from either source. In one embodiment, the identification devices 220, 232 automatically verify AMR (Automated Manifest Rule) information by downloading from the central system and comparing to visible items. As a result, the identification devices 220, 232 can verify AMR to a central security system, and inform an operator or agent as to whether correct goods are being loaded, unloaded, etc.
