Abstract: The present invention related to a technique for determining the progesterone-associated physiological state of a lactating cow. The technique comprises determining at least one Milk Solid (MS)-related parameter in at least one milk sample from a lactating cow; and determining the progesterone-associated physiological state according to the Milk Solid (MS)-related parameter. Determining the progesterone-associated physiological state may comprise determining the progesterone level of the cow by correlating the MS-related parameter with calibrated data. The MS related parameter may comprise at least one of size, synthesis, composition of a MS, a pattern of progesterone concentration or direction of progesterone concentration, or at least one dielectric parameter of the MS.

Abstract: System for determining the efficiency of publicity and/or broadcasted programs, comprising an audio signature generating unit with an adaptor that consists of a sampling unit for sampling the audio signal transmitted by the radio/TV at a first rate; a transformer, for obtaining galvanic separation between the power amplifier of the radio/TV, which feeds the loudspeakers and the input to the sampling circuitry. The audio signature generating unit is adapted to sample the audio signal transmitted by the receiver radio/TV that receives FM-radio/TV stations and to generate a characteristic audio signature. The system also comprises a plurality of stationary reference station units, each continuously listens to a station and is adapted to sample the audio signal transmitted by a particular broadcasting station to generate a stationary characteristic audio signature.
