Abstract: An apparatus for measuring, with infrared thermometers, temperatures of hatching eggs placed in nests of hatching trays which are arranged in an incubator, wherein, for a preselected number of trays, the temperature is measured of a predetermined number of eggs, wherein during the hatching period, each individual thermometer contactlessly measures the temperature around a corresponding individual egg arranged in the incubator according to a pre-entered measurement scheme, wherein the measuring signals obtained control a temperature control regulation.

Abstract: A method for processing bioresponse signals coming from organisms living in a well-defined living space, which are each comprised in a microenvironment, wherein these signals are obtained in online measuring of bioresponse variables, and wherein these signals are at least real-time processed in a signal processor, wherein, on the one hand, these organisms are monitored in the said microenvironments, and wherein, on the other hand, these variables can be adjusted by corresponding signal control apparatuses in accordance with a living space control model, wherein the living space comprises an incubator for hatching out hatching eggs, wherein the bioresponse variables are measured and controlled in a physical and/or chemical manner, for instance in the form of optical, electrical, magnetic, acoustic or mechanical bioresponse signals, or combinations thereof.

Abstract: The present invention describes a method and a system, which allows the prediction as well as the guiding of the bio-response of living organisms towards a predefined reference bio-response. A further embodiment of the invention is the use of the method in order to estimate the average weight of animals using an automatic weighing system.

Abstract: An air flow sensor and impeller flow for use in industrial, agricultural and civil applications as well as in process control, emission control and measurement. The impeller is suspended for free rotation in a tube section and has a central core and a number of impeller blades extending from the core wherein at least one blade extends from the core to the adjacent inner wall of the tube section. The flow sensor is equipped with measuring means to measure the number of revolutions of the impeller per unit of time and to register an associated calibration speed of the impeller.
