Claim 8

An article tracking system according to claim 3 or 4, wherein said passive radio frequency transmitter comprises an identification tag carrying data representing a particular physical location and an antenna operatively connected to said identification tag for defining the physical location represented by said identification tag.

Claim 9

An article tracking system according to claim 1, and including display means on said vehicle for displaying physical location information to the vehicle operator in order for the vehicle operator to confirm that the article has been taken to the correct physical location associated with that particular article.

Claim 10

An article tracking system according to claim 1, and including central display means associated with said computing means for permitting supervisory personnel to monitor the location of vehicles and thereby determine that articles carried by the vehicle have been delivered to the correct location.

Claim 11

An article tracking system comprising: (a) delivery zone transmitting means associated with at least one physical article delivery location for transmitting data identifying that physical location; (b) zone detecting means carried by at least one manually operated article delivery vehicle for detecting the physical proximity of the vehicle to the delivery zone; and (c) signal means operatively associated with said zone detecting means for outputting a signal indicating the physical proximity of the vehicle to the delivery zone; (d) article identification means for identifying an article and associating the identity of the article with said at least one article delivery location, wherein said article identification means associates the identity of the article with at least one article pick-up location; whereby an operator of the vehicle is informed that the vehicle is in the proper delivery zone for delivery of the article.

Claim 12

An article tracking system comprising: (a) delivery zone transmitting means associated with at least one physical article delivery location for transmitting data identifying that physical location; (b) zone detecting means carried by at least one manually operated article delivery vehicle for detecting the physical proximity of the vehicle to the delivery zone; and (c) signal means operatively associated with said zone detecting means for outputting a signal indicating the physical proximity of the vehicle to the delivery zone; (d) article identification means for identifying an article and associating the identity of the article with said at least one article delivery location, wherein said article identification means associates the identity of the article with at least one article pick-up location; whereby an operator of the vehicle is informed that the vehicle is in the proper delivery zone for delivery of the article.

Claim 13

An article tracking system according to claim 10, and including computing means, wherein said signal means includes signal relay means for relaying from said computing means to said vehicle the identity of the delivery zone where the article is to be delivered, and for relaying from the vehicle to the computing means the signal indicating the physical proximity of the vehicle to the delivery zone.

Claim 14

An article tracking system according to claim 11, wherein said computing means includes alarm means for sending an alarm signal to the vehicle if the vehicle enters an improper delivery zone and an alarm on said vehicle for generating an alarm to the vehicle operator.

Claim 17

A method according to claim 13, and including the steps of: (a) providing computing means; (b) providing signal relay means; (c) relaying from said computing means to said vehicle the identity of the delivery zone where the article is to be delivered; and (d) relaying from the vehicle to the computing means the signal indicating the physical proximity of the vehicle to the delivery zone.

Claim 18

A method according to claim 13 or 14, and including the steps of: (a) providing physical identification means for identifying an article; and (b) associating the identity of the article with said at least one article delivery location.

Claim 19

A method according to claim 15, and including the step of associating the identity of the article with at least one article pick-up location.

Claim 20

A method according to claim 14, wherein said computing means includes alarm means for sending an alarm signal to the vehicle if the vehicle enters an improper delivery zone and an alarm on said vehicle for generating an alarm to the vehicle operator.

Claim 21

A method according to claim 13, and including the step of: (a) providing an article pick-up zone transmitting means associated with at least one physical article pick-up location for transmitting data identifying that physical location.

Claim 22

A method according to claim 18, wherein said pick-up zone transmitting means comprises a passive radio frequency transmitter and a zone detecting means comprises a radio frequency interrogator/detector for generating a detection signal for the pick-up zone transmitting means to transmit in response thereto.

Claim 23

A method according to claim 13, wherein said delivery zone transmitting means comprises a passive radio frequency transmitter and said delivery zone detecting means comprises a radio frequency interrogator/detector for generating a detection signal for the delivery zone transmitting means to transmit in response thereto.
