Abstract: A pulsimeter for indicating the average heart beat rate by counting the number of beats occurring during a predetermined period of time, comprising a pulse sensor adapted for flat application against a part of a human body, and an electronic counter and display preferably arranged for being worn on a person's wrist. The electronic counter and display comprise an input processing circuit which receives electrical pulses at the rate of the heart beats from the pulse sensor and which supplies to a counting circuit an electrical signal having n pulses for one heart beat, n being an integer factor of 60 greater than 1 and less than 60. The counting circuit repeatedly counts the pulses from the input processing circuit during the predetermined period of time, the duration of which is 60/n seconds. The counting circuit is reset at the end of each such period of time, just after having transmitted its end counting value to a memory circuit which supplies this value to a display during the whole next period of time.

Abstract: an electronic watch-chronograph comprising a watch portion having an electronic arrangement for the measurement and display of the time of day, and a chronograph portion having an electronic arrangement for the measurement and display of the duration of a period of counted time, the first-mentioned display comprising statically-controlled display elements and the second-mentioned display comprising electroluminescent display elements.
