Chronography for scientific experiments - uses circle of LEDs to indicate fractions of second, with numeric second display at centre

摘要

The chronograph (1) is designed for indicating time during scientific or physics experiments. It has electroluminescent diodes (2) arranged in a circle of the face (3), of the chronograph. These diodes make up the reference points for the indication of fractions of a second. The face (3) may also carry one hundred electroluminescent diodes (2) arranged on a circle. The make up reference points indicating hundredth of a second. For indication of records and or minutes other diodes are arranged on a smaller diameter circle than that indicating fraction of a second. A numerical indicator (6) may be placed in the centre of the circle to indicate records or minutes.
