Abstract: Harvesting head to be installed on a traveling carrier and configured to straddle a row of fruit-bearing plants, during operation, so as to harvest berries or small fruit such as, for example, grapes, black currants, gooseberries, raspberries, olives is the present invention. The harvesting head is dependent on one or more a device imparting movements during operation, the movements on either side being in relation to the median vertical plane of a straddling carrier on which the harvesting head is mounted. The device is controlled by at least one control system and capable of centering at least the lower part of the harvesting head in relation to the plants in rows.

Abstract: The method for analysing the structure of cultured hedges, equally applicable by day or by night, for a mobile, continuously-moving machine in tied or staked plantations such as vineyards, includes a system using an artificial vision system, working by transmission, which permits a detection of the shadowing of the light between one or more transmitters and one or more detectors to one side and the other of the hedge. The information generated by said shadows of light are processed by an electronic analysis system, programmed or embodied to examine the elements of the structure of the hedge.

Abstract: An electronic anti-skid device for motor vehicles with hydrostatic transmission has at least one sensor for the transmission of data pertaining to the output of the hydrostatic transmission, a steering angle detector and an electronic computer. The electronic computer uses data from the sensor to calculate theoretical power output of the hydraulic motors of the driver wheels of the vehicles and, thus, the theoretical speed of the wheels. The electronic computer is programmed to scan the detectors at very rapid intervals, and to adjust, on each scan, hydraulic output from output regulators. The output regulators have electrical controllers and are coupled to each hydraulic motor of a driven wheel way as to limit the power from each regulator to a value marginally above the theoretical output for the motor of the wheel to which the power regulator is connected.
