A process is provided for the automatic control of a respirator for changing over (triggering) between consecutive phases of respiration (inspiration and expiration phases), wherein a pneumatic breathing activity signal upneu(t) and a non-pneumatic breathing activity signal unon-pneu(t) of a patient are picked up. The intervals Δpneu(t) and Δnon-pneu(t) to the associated threshold variables are respectively determined starting from a preset reference point in time since the beginning of the present phase of respiration. The intervals are standardized to one another at δpneu(t) and δnon-pneu(t), such that the intervals have equal interval values at a preset reference point in time. The standardized intervals δpneu(t) and δnon-pneu(t) are averaged to a mean interval indicator and a changeover is made into the next phase of respiration when the combined interval indicator is 0.

In a method for modulation of a basic clock for digital circuits, in which the intervals between adjacent switching edges are varied, with the basic clock being split into equidistant sections, and the intervals between adjacent switching edges being varied as a function of cyclically recurring random numbers, the position of a switching edge (ai+1) following a switching edge (a1) to be calculated as follows: a i + 1 = ( a 1 + p - ( N - 1 2 - Z i + 1 ) ) mod p where p is the number of equidistant sections per half-cycle N is the number of possible switching edges, with N being an odd number, and Z is the random number. A corresponding modulator uses the method described above in an equivalent manner.

A device for determining the body core temperature of a living being includes a first temperature sensor (15) for detecting the skin temperature T1, an insulator (11) for receiving the first temperature sensor (15), a second temperature sensor (17) in the insulator (11) for detecting a temperature T2 and a third temperature sensor (19), which is arranged opposite the first temperature sensor (15) at the insulator (11), for detecting a temperature T3 near the environment. Assuming a constant ratio of lateral heat fluxes α at the insulator (11) between the temperature sensors (15, 17, 29), the body core temperature Tcore is determined by the relationship described by the formula T core = T 1 · [ 1 + k s k g ( 1 + 1 α ) ] - T 2 · ( k s k g + k s + k t α k g ) + T 3 · k t α k g in which kg=heat transfer coefficient of the tissue and ks, kt=heat transfer coefficients of the insulator (11).
