Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A taximeter comprising: processing means for calculating a taxi fare; random access memory means having first and second memory areas for storing tariff information; date input means operable under the control of the processing means for loading the first memory area with said tariff information relating to a first tariff and for loading the second memory area with said tariff information relating to a second tariff; coupling means for coupling the first memory area with the processing means so as to enable the processing means to calculate a taxi fare in accordance with the first tariff; and changeover means operable in response to a predetermined command signal for coupling the processing means with the second memory area so as to enable the processing means to calculate thereafter a further taxi fare in accordance with the second tariff.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
A taximeter as claimed in claim 1, wherein the changeover means enables the processing means in accordance with time and date information stored in the storage means.
Claim 4
Dependent Claim
37 words
A taximeter as claimed in claim 2, wherein the changeover means enables the processing means the first time the taximeter is set to a `FOR HIRE` mode following the elapse of the stored time and date information.
Claim 5
Dependent Claim
43 words
A taximeter as claimed in claim 1, wherein the changeover means enables the processing means after the elapse of a specified time measured from the time when the proposed tariff structure information is entered in the storage means by the data input means.
Claim 6
Dependent Claim
22 words
A taximeter as claimed in claim 1, wherein the changeover means enables the processing means in accordance with a received radio signal.
Claim 7
Dependent Claim

A taximeter as claimed in claim 5, wherein the received radio signal includes an enabling code.
Claim 8
Dependent Claim
17 words
A taximeter as claimed in claim 6, wherein the enabling code is stored in the storage means.
Claim 9
Dependent Claim
25 words
A taximeter as claimed in claim 1, wherein the changeover means enables the processing means in accordance with a command signal keyed into the taximeter.
Claim 10
Dependent Claim
22 words
A taximeter as claimed in claim 8, wherein the command signal is keyed into the taximeter using a control of said taximeter.
Claim 11
Dependent Claim
20 words
