Abstract: Berry, such as grape, harvesting machine includes a plurality of superimposed shakers formed by flexible bars, and attached through their ends to two vertical shafts. At least one shaft is an oscillating actuation shaft controlled by a mechatronic shaking control permitting an oscillating movement. The mechatronic shaking control includes an eccentric system connected to the actuating shaft through a connecting rod, and the rotation axis of the eccentric system is mounted with an orientation adjustable in a plane parallel to the median plane of the machine so that any modification of this orientation permits to modify the amplitude of the oscillating movement of the actuating shaft, and, consequently the amplitude of the shaking movement of the shakers.

Abstract: Shaker with adjustable stiffness for harvesting machines, especially grape harvesters, includes two berry detaching assemblies, facing each other. Each assembly includes a plurality of vertically spaced out flexible shakers, having the general shape of a hairpin and two branches connected through a curved portion. The end of one of these branches, the activation branch, connects to an actuation system while the end of the other branches connects to a fixed support. The activation branch is equipped with a mechanism to modify the degree of stiffness or flexibility of the branches over at least a portion of length, and thereby, to adjust the degree of stiffness or flexibility of the shaker assembly.

Abstract: Sorting table with sorter rolls eliminates foreign matter remaining mixed in with the products of the harvest of small fruit. The present invention features a sorting system constituted by a succession of rotating rolls of cylindrical shape arranged in parallel so as to form a mobile sorting plane, and a locomotion device, allowing the rotating drive of the rolls in the same direction, so as to allow transporting the grapes dumped on the upstream part of this sorting plane, in a direction that is perpendicular to the axis of the rotating cylindrical rolls and over the entire length of the sorting plane. The rotating cylindrical rolls are laid out so as to allow the passage and drop-off of only the small fruit to be sorted, whereas the foreign matter of a size larger than that of the latter remains on the surface of the mobile sorting plane and is evacuated at the downstream end of it.

Abstract: An equilibrated charging method for n cells of a lithium-ion or lithium-polymer battery, connected in series.

Abstract: The invention relates to vibrating tongs, including two opposing jaws in which the closing or opening movements are achieved through one or several hydraulic jacks, referred to as clamping jacks. These tongs are especially remarkable in that the oil intake chamber or pressure chamber of the clamping jacks that control the closing motion of the jaw or jaws, is linked to a mechanism fitted to detect any pressure rise inside the chamber that occurs when the tong jaws come into contact with the trunk of a tree. Blocking devices are controlled by the detection mechanism, and any increase in the pressure of the jaws on the trunk is opposed as soon as such a pressure rise occurs in the oil intake chamber.
