Abstract
Abstract A system for allowing an automatic guided vehicle (AGV) to move from a first guided area to a second guided area across an unguided span that separates them. A first guidance structure such as a buried cable is displaced from a second guidance structure. A communications and traffic controller is connected to each of the first and second guidance structures. Also connected to the communications and traffic controller is a transponder for signalling when an AGV is leaving the first guided area.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
222 words
A system for allowing an automatic guided vehicle (AGV) to move from a first guided area to a second guided area across an unguided span therebetween, comprising: (a) a first guidance means associated with a first guided area; (b) a second guidance means associated with a second guided area, said second guidance means being displaced a predetermined distance from said first guidance means, said predetermined distance defining an unguided span; (c) at least one communications and traffic control means including a high speed communications processor means operatively connected to each of said first and second guidance means for facilitating communications between said first and second guidance means in accordance with a predetermined protocol; (d) means operatively connected to said communications and traffic control means for signalling when an AGV is leaving said first guided area; (e) means operatively connected to said communications and traffic control means for signalling when an AGV is entering said second guided area; (f) master control means operatively connected to at least one of said communications and traffic control means for facilitating communications between a plurality of communications and traffic control means; and (g) a local area controller operatively connected to said master control means, said master control means facilitating communications between said local area controller and said at least one of said communications and traffic control means.
Claim 2
Independent Claim
222 words
A system for allowing an automatic guided vehicle (AGV) to move from a first guided area to a second guided area across an unguided span therebetween, comprising: (a) a first guidance means associated with a first guided area; (b) a second guidance means associated with a second guided area, said second guidance means being displaced a predetermined distance from said first guidance means, said predetermined distance defining an unguided span; (c) at least one communications and traffic control means including a high speed communications processor means operatively connected to each of said first and second guidance means for facilitating communications between said first and second guidance means in accordance with a predetermined protocol; (d) means operatively connected to said communications and traffic control means for signalling when an AGV is leaving said first guided area; (e) means operatively connected to said communications and traffic control means for signalling when an AGV is entering said second guided area; (f) master control means operatively connected to at least one of said communications and traffic control means for facilitating communications between a plurality of communications and traffic control means; and (g) a local area controller operatively connected to said master control means, said master control means facilitating communications between said local area controller and said at least one of said communications and traffic control means.
