Abstract
Abstract An electronic taximeter comprises a time reference pulse source, a distance travelled pulse source, a time measuring circuit, a level detector, a gate circuit and a fare indicator. When the vehicle is stopped or is running below a selected speed pulses are supplied by the time reference pulse source to actuate the fare indicator while any pulses from the distance travelled pulse source are blocked by the gate. When the vehicle is running at a speed higher than the selected speed, as determined by the time measuring circuit and level detector, the gate is opened so that pulses from the distance travelled pulse source are admitted to the fare indicator and the time reference pulse source is disabled.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
Taximeter arrangement in which time and distance information in the form of electric impulses is used for forward stepping of a fare indicator 13, said arrangement comprising, on the one hand, two impulse sources 1, 10, 11 one of which 10, 11 produces time reference impulses where the other one 1 produces distance impulses, and on the other hand, an impulse handling member 9 controlling said fare indicator 13, said taximeter arrangement being adapted to a time-depending rate below a certain predetermined speed and to a distance-depending rate above said speed, characterized by a speed meter 6, 7 which dependent on the speed of the vehicle during transition through the predetermined speed from a lower to a higher speed, on the one hand, opens a gate 8 for the distance impulses to supply these impulses to the impulse handling member 9 and, on the other hand, stops the impulse source 10, 11 also connected to the fare indicator 13 and producing time reference impulses which then cease to feed the fare indicator 13, and vice versa, in order to bring about independently of the mutual frequency relation of the time and distance impulses the change between the time rate and the distance rate.

Claim 3
Dependent Claim
26 words
Arrangement as claimed in claim 1, characterized in that the impulse source 10, 11 comprises a frequency divider 11 which is adjustable for various time rates.
