Abstract: PROBLEM TO BE SOLVED: To integrate passengers, baggages, cargoes, and containers by a single communication base without necessitating manual intervention at the time of reading data by providing an interrogator for transmitting a down-lank signal, and receiving a up-link signal, and a tag for receiving the down-link signal, and transmitting the up-link signal. SOLUTION: This system is provided with a radio frequency identifying system using a modulating back scatter, and a tag for transmitting data a various data rates is used. For example, a cargo container 810 having a container tag 820 is loaded through a door 840 of a cargo bay on an airplane 860. The container tag 820 is fixed to the cargo container 810, and the cargo container 810 can be identified when it is allowed to pass through a cargo handling facility, and the entrance or exit of the air plane or the like. An interrogator 103 at the upper part of a crane 850 reads an airplane tag 830, and communicates identification information indication which baggage, cargo, and container is loaded on the airplane 860, and the identification information of the door 840 of the cargo bay to a handling system.

Abstract: In accordance with the present invention, a radio frequency identification system, using modulated backscatter radio communications, is disclosed which supports the automated reconciliation of passengers, baggage, an d cargo on a transport. A baggage tag is attached to each piece of checked baggage , where the baggage tag is a read-only tag with modulated backscatter radio capabi lity. Thus, each piece of checked baggage can be identified for sortation, and also identified to ascertain if it has been loaded onto a particular aircraft. Pieces of baggage can be either loaded directly onto an aircraft, or loaded onto a cargo container; where a cargo tag is attached to the cargo container, the cargo tag i s a read-write tag with modulated backscatter radio capability. The aircraft itself may be equipped with aircraft tags, which could be read-only or read-write tags with modulated backscatter radio capability. Aircraft tags allow a positive associati on between the identity of the baggage or cargo container being loaded, the aircraf t on which it is being loaded, and the cargo bay doorway through which it is being loaded. To identify passengers, several alternatives are disclosed. In one embodiment, a magnetic boarding pass can be used with a magnetic stripe containi ng information about this passenger. In this embodiment, the passenger is responsib le for inserting the magnetic boarding pass into a magnetic card reader as the pass enger boards the flight. In another embodiment, a radio boarding pass could be used. T he radio boarding pass resembles a conventional boarding pass, however it has readonly modulated backscatter radio capability, perhaps identical with the technology used for the baggage tag. The radio boarding pass can be read as the passenger boards the aircraft. In an alternate embodiment, the passenger can have a passen ger card, which is a read-write tag with modulated backscatter capability. The passe nger card can be read as the passenger boards the aircraft, to identify the passenger . Alternately, the passenger card can be used for a number of enhanced passenger service applications in a generalized transportation environment.

Abstract: In accordance with the present invention, a radio personal communications device is disclosed, which is capable to receiving modulated radi o signals, and capable of transmitting modulated radio signals using modulated backscatter technology. This device can operate in an Interrogation Mode, in whi ch a set of mandatory data is transmitted from the device; in a Location Mode, in w hich the approximate location of the device can be determined, and in a Messaging Mod e, in which data can be transmitted to and received from the device. The device is capable of transmitting information, using modulated backscatter, at more than o ne data rate. The device contains a display to display some or all of the data tran smitted to the device. Alternate embodiments of the invention allow the device to also support pushbuttons to allow data to be input to the device. Alternate embodimen ts support a variety of powering mechanisms for the device, including batteries, ch arge storage devices, solar cells, a coil or other energy transfer device, etc. A rec harging station is also disclosed in the event the power supply of the device requires recharging.
