Abstract: The invention relates to a method of acoustically monitoring the course of a process, in which method the amplitude difference and/or the intensity value of sound are/is measured during the process, and the amplitudes and/or the intensity values of the sound and/or the vibrations are measured continuously or with an adjustable frequency by means of a sound and/or vibration sensor (4), such as a piezoelectric transducer (12), during the entire process or part of the process and are compared mutually and/or with a predetermined threshold value and/or reference value and/or reference pattern for the purpose of drawing, on the basis thereof, conclusions in relation to the progress and/or the course of the process and/or the presence of disturbances and/or deviations in the course of the process.

Abstract: An apparatus for demarcating an area for restricting the freedom of movement of animals that may be in the area for grazing purposes. The demarcation element, as such, may be a cord, band, ribbon, strip, cable, rope or electrified or communication wire which may be two parallel wires separated by a flexible insulating material. The demarcation element is supported by a plurality of vehicles although one or two ends of same may be secured at a reference point. The vehicle is supported by two relatively large wheels which are independently connected to motors and the center of gravity of vehicle is lower than the centers of the wheels which may be perpendicular to the ground or slanted inwardly. The vehicle carries solar panels which may be mounted on the wheels if they are slanted. A connection for the demarcation element is carried on each vehicle which may include a guide member and tightening device.

Abstract: The invention relates to an implement for automatically detaching and displacing an amount of feed, such as for example silage and/or hay, from a stock of feed, said implement 1 being provided with a robot arm 2 with a detaching member 3 which is suitable for detaching a part of the feed from the stock and displacing it to a predetermined place and depositing it there.

Abstract: A method and device for making measurements of the characteristics of a fluid, particularly the milk, which flows in pulsations in a conduit. The device has a measuring region wherein at least one characteristic of the fluid is determined. The measurement is made during an optimal measuring window which constitutes a time interval while a pulsation of the fluid is received in the measuring region which contains a sensor or sensors for measuring one or more selected characteristics of the fluid, such as color, conductivity or acoustic qualities. The measuring region may be in a bypass passageway in the conduit which may be incorporated in a teat cup. The pulsations in the teat cup may be used to define an optimal measuring window for measuring one or more characteristics of the fluid as it flows in pulsations through the conduit. The sensed entry or approach of a pulsation into the measuring region may also be used to define the optimal measuring window.
