摘要： A system and a method for refrigeration and thermal conditioning of a body having a first circuit for refrigeration of the body and a second circuit for thermal conditioning of the body. The first circuit has a first reservoir for storage of a cold liquid coolant component and a first pump for pumping the cold coolant component from the first reservoir to a portion of the body, and for returning the cold coolant component to the first reservoir. The second circuit has a second reservoir for storage of a hot liquid coolant component and a second pump for pumping the hot coolant component from the second reservoir to the portion of the body, and for returning the hot coolant component to the second reservoir once the coolant has been applied, for a given time, to the portion of the body.

摘要： A long range low frequency antenna having an elongated magnetic core; a coil surrounding the elongated magnetic core; a bobbin; where the elongated magnetic core is introduced in a cavity of the bobbin; and a housing overmolded on the bobbin in a waterproof manner. The antenna also comprises at least one damper located at one extreme of the elongated magnetic core. The at least one damper is made of an elastic and thermally-stable compound having a resin and a first filler including a natural mineral filler. Therefore, longitudinal dilatations, shrinkage, mechanical shocks, and vibrations of the elongated magnetic core are absorbed by the at least one damper, avoiding an impact over an inductance variation of the coil.
