Patent number: 4389563Abstract: This anti-fraud system includes a process and devices for avoiding fraud on the price indicated by an electronic taximeter. The taximeter apparatus, which includes a luminous display unit and a computing unit, is supplied with d.c. voltage V by the vehicle battery. One particular fraud, made more difficult by this system, involves voluntary cut-off of the voltage supply to the meter. To execute this fraudulent maneuver the cabdriver firstly starts the meter, and records a price on the fare meter, with no passenger in the taxi. Secondly, before a customer is picked up, the operator cuts off the current supply to the meter, which extinguishes the fare display. Thus, as the customer enters the cab, it is not apparent that the meter has already been run-up to a non-zero value. To preclude this maneuver, the anti-fraud system has a first comparator which compares the voltage V with a reference voltage Vr and emits a constant voltage Vc if V<Vr and a zero voltage if V>Vr.Type: GrantFiled: October 6, 1980Date of Patent: June 21, 1983Inventor: Claude F. Ricard

Patent number: 4056709Abstract: A digital taximeter provides a visual read out of a first and a second multi-digit number. Instead of a plurality of discrete one-digit illuminated-digit display units arranged together to be capable of displaying multi-digit numbers, use is made of a single multi-digit illuminated-digit display unit having a row of equal-size digit zones. One or more of the middle ones of the digit zones are blocked from view to form a first and a second group of digit zones respectively adapted for the display of the first and the second multi-digit numbers and located to either side of the digit zones which are blocked from view. Although the digit zones are actually all of the same size, those of the first group are made to appear larger than those of the second group, in correspondence to the greater importance of the fare indication compared to the extra-charge indication.Type: GrantFiled: June 13, 1975Date of Patent: November 1, 1977Assignee: Kienzle Apparate GmbHInventors: Hans-Peter Scholl, Alfons Heimburger, Ulrich Warkentin, Manfred Saufferer

Patent number: 3937933Abstract: The taxi meter receives a sequence of pulses each representing a determined distance travelled by the taxi. The repetition rate of the input pulses is to be reduced by a ratio T so that each pulse having the reduced repetition rate signifies a determined fare increment. An adder or counter has a determined capacity and furnishes a carry signal whenever the sum signal created therein exceeds that capacity. An addend equal to K/T where K is the capacity of the adder is applied to the input of the adder for addition therein in response to each of the input pulses. The carry signals furnished by the adder constitute the desired signals each signifying the correct fare increment. The repetition rate of pulses each signifying a unit of waiting time can be similarly reduced and the resulting carry pulse sequences be applied to a selection circuit which selects the one having the highest repetition rate to constitute the tariff signal, namely the signals for advancing the taxi meter by one fare increment.Type: GrantFiled: December 3, 1974Date of Patent: February 10, 1976Assignee: Kienzle Apparate GmbHInventor: Ulrich Warkentin
