摘要:
An assembly for performing an agricultural operation, in particular crop processing. The assembly is provided with an autonomous agricultural machine that is movable over a parcel for performing the agricultural operation, the agricultural machine includes a machine container detachably disposed on the agricultural machine for containing an amount of the product required for performing the agricultural operation. A container for containing a stock of a product required for performing the agricultural operation is also provided and a control-unit automatically moves the agricultural machine to the container where a conveying device automatically exchanges the container with the machine container. Due to the fact that the machine container can be exchanged automatically and quickly with an exchange container, the assembly is relatively efficient in use.

An assembly for performing an agricultural operation, in particular crop processing. The assembly is provided with an autonomous agricultural machine that is movable over a parcel for performing the agricultural operation and with a control unit for controlling the functioning of the autonomous agricultural machine. The control unit is provided with a memory containing sound-standard data. The control unit controls the functioning of the autonomous agricultural machine with the aid of the sound-standard data. An autonomous agricultural machine for performing the agricultural operation. The autonomous agricultural machine is provided with a control unit for controlling the functioning of the autonomous agricultural machine, with a position-determining system for determining the momentary position of the agricultural machine in the parcel, and with a sound meter. The control unit is provided with a memory containing sound-standard data. The control unit controls the functioning of the autonomous agricultural machine with the aid of the sound-standard data and/or data from the sound meter.
摘要:
A lithographic apparatus is disclosed. The apparatus includes an illumination system for conditioning a beam of radiation, and an article support for supporting a substantially flat article to be placed in the beam of radiation. The article support includes a plurality of supporting protrusions for supporting the article, and at least one protective member located near a boundary of the supporting protrusions for protecting at least a boundary portion of the supporting protrusions during release of the article. The apparatus also includes a releasing device for releasing said article from said article support.

A method is disclosed for impregnating a layer of fibre material with a curable liquid so as to obtain a product of composite material, in particular an upright such as a lamppost or light mast or a post for a traffic light, a road sign, or for a direction sign. The method includes providing a mould, arranging a layer of the fibre material against a surface of the mould, arranging a covering layer over the fibre material in order to enclose the layer of fibre material between the mould and the covering layer, providing the curable liquid, and applying an underpressure to the space defined by the mould and the covering layer in order to enhance distribution of the liquid through the layer of fibre material wherein the mould is formed by a flexible element. The method further includes deploying the flexible element in a desired form.
摘要:
A lithographic projection apparatus having a radiation system for providing a projection beam of radiation; a support structure for supporting a patterning device, the patterning device serving to pattern the projection beam according to a desired pattern; a substrate holder for holding a substrate the substrate holder provided with a device to provide a holding force for pressing the substrate against the substrate holder; a releasing structure constructed and arranged to eject the substrate from the holder against the holding force; and a projection system for projecting the patterned beam onto a target portion of the substrate. The lithographic projection apparatus may include a controller for controlling the releasing structure so as to release the substrate from the holder with a release force that is reduced prior to final release.
