Abstract: There is provided an autonomous vehicle for pushing feed lying on a floor, comprising a frame; a skirt rotatably connected to the frame, wherein a bottom portion of the skirt continuously contacts the floor to push the feed. The vehicle comprises a sensor assembly for detecting a magnetic field emitted from a magnetic guiding element inserted in the floor and a control unit mounted for directing rotation of the skirt and for guiding the vehicle along a predetermined path formed by the magnetic guiding element. Also provided is an autonomous vehicle with a skirt drive mechanism mounted to the frame for driving rotation of the skirt, and an autonomous vehicle comprising a prism-shaped skirt rotatably connected to the frame. There is also provided methods for installing a magnetically guided autonomous vehicle and for pushing feed using an autonomous vehicle, as well as systems and kits comprising said vehicle.

Abstract: An electric signal digitizing device includes a line of propagation through which the signal travels and a plurality of samplers (141, . . . , 14N) connected at separate points on the line of propagation, such that each one samples the signal value at the connection point thereof. The device further includes an analog matrix memory including a line of which at least some elements are each connected to a sampler of the plurality of samplers to receive the value sampled by the sampler, and a means for the line-to-line shifting of stored values. An analog-digital conversion means is also provided for the analog-digital conversion of the stored values.

Abstract: Device for automatically centring a laser beam in a light guide and method of manufacturing this device. This device comprises a volume scatterer (2) to scatter a laser beam and automatically centring it in a light guide (32), for example a monomode or multimode optical fibre. To manufacture the device, a tubular light guide (6) is manufactured and the volume scatterer is made from a material scattering light, using the tubular light guide as a cutting punch.

Abstract: The invention concerns a device for sealing a bottle containing a sparkling wine and includes a stopper, particularly made of cork or a synthetic material, capable of being inserted in the neck of the bottle, maintained thereon by a wire cap, and run through in the axial direction, by a conduit having first and second ends capable of communicating respectively with the bottle's internal volume and external volume. The second end is closed by a retractable closer. The device is characterized in that the stopper is axially run through by an orifice designed to receive the conduit and having an adjusted and tight cross-section relative to the conduit external section, the latter being provided at its second end, with a support flange capable of resting against the stopper upper surface.
