Abstract
Abstract A single taxi is provided with an electronic taximeter which includes fare computing circuitry operative for separately computing the fares of a plurality of passengers whose respective trips overlap. A fare display device is operative for displaying the computed fares associated with the respective passengers. A coordinating arrangement is activatable for initiating computation of the fare associated with a respective passenger when such passenger enters the taxi and is furthermore activatable for terminating the computation of the respective fare when the respective passenger leaves the taxi.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
In a single taxi, an electronic taximeter comprising, in combination, fare computing means for separately computing the fares of a plurality of passengers whose respective trips overlap, said fare computing means including coordinating means activatable for initiating computation of the fare associated with a respective passenger when such passenger enters the taxi and activatable for terminating the computation of the respective fare when the respective passenger leaves the taxi; and fare display means connected to said fare computing means for displaying the computed fares associated with the respective passengers.
Claim 2
Dependent Claim
89 words
In a single taxi, an electronic taximeter comprising, in combination, fare computing means for separately computing the fares of a plurality of passengers whose respective trips overlap, said fare computing means including coordinating means activatable for initiating computation of the fare associated with a respective passenger when such passenger enters the taxi and activatable for terminating the computation of the respective fare when the respective passenger leaves the taxi; and fare display means connected to said fare computing means for displaying the computed fares associated with the respective passengers.
Claim 3
Dependent Claim
41 words
A taximeter as defined in claim 1, wherein said fare display means comprises a plurality of fare display devices and means for causing said plurality of fare display devices to simultaneously display the respective computed fares for said plurality of passengers.
Claim 4
Dependent Claim
77 words
A taximeter as defined in claim 1, wherein said fare display means comprises a single display device capable of displaying at any one time the fare for only one of said plurality of passengers, and selecting means connected both to said fare computing means and to said single display device and manually activatable by the taxi driver for causing said single display device to display the computed fare for any selected one of said plurality of passengers.
Claim 5
Dependent Claim
75 words
A taximeter as defined in claim 1, wherein said fare display means comprises a single display device capable of displaying at any one time the fare for only one of said plurality of passengers, and selecting means connected both to said fare computing means and to said single display device and for automatically causing said single display device to display in cyclical order successive ones of the fares being computed by said fare computing means.
Claim 6
Dependent Claim
102 words
A taximeter as defined in claim 1, and further including fare subtotal computing means for computing the total fare collected from a plurality of passengers during one trip and cumulative total fare computing means for computing the cumulative total of fares collected during a plurality of trips, and selector means connected to said fare subtotal computing means and to said cumulative total fare computing means and to said fare display means and for selectably causing said fare display means to display either the value computed by said fare subtotal computing means or the value computed by said cumulative total fare computing means.
Claim 7
Dependent Claim
93 words
A taximeter as defined in claim 1, wherein said fare computing means comprises means for determining the number of passengers riding concurrently at any time, and means for computing the fare for each passenger during each portion of the trip of such passenger at a first rate when such passenger rides alone during such portion, at a lower second rate when such passenger shares the taxi with one additional passenger during such portion, and at a third still lower rate when such passenger shares the taxi with two additional passengers during such portion.
Claim 8
Dependent Claim
76 words
A taximeter as defined in claim 1, wherein said fare computing means comprises means for determining the number of passengers riding concurrently at any time, and means for automatically computing the fare for each passenger during each portion of the trip of such passenger at a first rate when such passenger rides alone during such portion and at a lower rate when such passenger shares the taxi with one or more additional passengers during such portion.
Claim 9
Dependent Claim
66 words
A taximeter as defined in claim 1, wherein said fare computing means comprises means for determining the number of passengers riding concurrently at any time, and means for automatically changing the rate at which the fare for each passenger is computed during each portion of the trip of such passenger in dependence upon the number of passengers concurrently riding during each such portion of the trip.
Claim 10
Dependent Claim
56 words
A taximeter as defined in claim 8, wherein said fare computing means further includes means manually activatable to effect additional changes in the rate at which the fare for each passenger is computed, to permit the taxi driver or owner to employ different fare computation rates for day rides, night rides, holiday rides, and the like.
Claim 11
Dependent Claim
93 words
A taximeter as defined in claim 1, wherein said coordinating means comprises a plurality of coordination keys insertable into and withdrawable from respective keyholes in said taximeter and respectively corresponding to different passengers, and means for initiating the computation of the fare associated with a respective passenger when a respective one of said keys is withdrawn from the respective keyhole when the respective passenger enters the taxi and for terminating the computation of the respective fare when the respective key is reinserted into the respective keyhole when the respective passenger leaves the taxi.
Claim 12
Dependent Claim
43 words
A taximeter as defined in claim 10, wherein said coordination keys and said respective keyholes are complementarily configurated and wherein each coordination key has a different configuration, thereby preventing insertion of any one of said coordination keys into any but one associated keyhole.
Claim 13
Dependent Claim
61 words
A taximeter as defined in claim 10, wherein said fare computing means comprises a plurality of storage locations, and wherein said coordinating means further includes switch means controlled by said coordinating keys and encoding means connected to and controlled by said switch means and for addressing different ones of said storage locations in dependence upon the setting of said switch means.
