Abstract (en)

[origin: WO2007104390A2] The invention relates to a device for determining a vital parameter of a living being, comprising a device having a receiving unit (105) and an extraction unit (120). The receiving unit (105) is adapted to receive repetitive optical signals (110, 175). The optical signal has sequences and has one sequence of at least two bright intervals in which a transmitter light source assumes an ON state, and at least one dark interval in which no transmitter light source assumes an ON state, the at least two bright intervals in a sequence being unevenly distributed. The device also comprises an extraction unit (120). Said extraction unit (120) extracts information on the vital parameters from a received signal, the extraction unit (120) being adapted to extract, based on the information on the distribution of the bright intervals in the sequence, a value of a variable pointing to a vital parameter.
