摘要:
An alternating drive for wheeled vehicles comprises two opposite pedals which can move on a circular path about a pedal shaft secured on the cycle frame. The alternating drive is characterized in that it is equipped with two cranks (26, 27; 26a, 27a; 26b, 27b) which can be moved within a predetermined oscillating angle range about an auxiliary shaft (25) secured to the frame (10). Between the cranks (26, 27; 26a, 27a; 26b; 27b) and the pedals (21) is a driver connection which transforms the circular motion into an alternating oscillating motion with phases mutually offset by a half oscillation period. Disposed on each side of the axle (50) of the driven wheel (12) is a free-wheel mechanism (56, 57). The free-wheel mechanisms (56, 57) lock in opposite directions and are connected to the individual cranks (26, 27; 26a, 27a; 26b, 27b) by mutually independent traction elements (29; 82, 83).

摘要:
A method for storing run data of a vehicule in the memory of an electronic tachograph, in which data representing the velocity and distance taken by the vehicle are read in subsequent cells of an accident memory (31) which has a substantially smaller storage capacity than a data memory (32) storing the run data in a first rate substantially higher than a sampling rate associated with a prescribed accuracy, and the maximum and minimum values of the velocity and the value of said distance are determined during periods following each other with the sampling rate, and at least said minimum and maximum values of the velocity data and the distance value are entered in the data memory (32) in each sampling period, and the content of the accident memory (31) is shifted forward with said first rate and the content of the data memory (32) is shifted forward with said sampling rate, thus the accident memory (31) stores detailed data of the always last road section which can assist both in investigating the detailed run data of an accident and in generating the extreme values ot the velocity for efficient long-term storage in the data memory (32).
摘要:
Dans le procédé décrit, des données représentant la vitesse et la distance à parcourir par le véhicule sont enregistrées dans des cellules subséquentes d'une mémoire d'avaries (31) qui possède une capacité de stockage sensiblement inférieure à une mémoire de données (32) stockant les données de roulement à une première vitesse sensiblement supérieure à une vitesse d'échantillonnage associée à une précision prescrite. Les valeurs maximale et minimale de la vitesse et la valeur de ladite distance sont déterminées pendant des périodes successives à la vitesse d'échantillonnage, et au moins lesdites valeurs minimale et maximale des données de vitesse ainsi que la valeur de la distance sont introduites dans la mémoire de données (32) à chaque période d'échantillonnage. Le contenu de la mémoire d'avaries (31) est avancé à la première cadence et le contenu de la mémoire de données (32) est avancé à ladite cadence d'échantillonnage. Ainsi, la mémoire d'avaries (31) stocke des données détaillées du tout dernier tronçon routier parcouru, qui peuvent aider à la fois à rechercher toutes les données de roulement détaillées d'une avarie et à produire les valeurs extrêmes de la vitesse en vue d'un stockage efficace à long terme dans la mémoire de données (32).
