摘要:
A radio-frequency identification tag for identification of cryo-preserved samples down to cryogenic temperatures, comprising an antenna (2, 3) and an integrated circuit chip (4) designed to be operative at cryogenic temperatures. The antenna is formed by a coil (3) wound around a ferrite core (2). The radio-frequency identification tag is configured to fit within a vessel having a diameter down to 1.4mm. A system for identification of cryo-preserved samples at cryogenic temperatures. A method of tuning a radio-frequency identification tag for identification of a cryo-preserved sample stored in a vessel at cryogenic temperatures.
摘要:
The invention relates to an integrated temperature sensor (1) comprising: means (2000) for generating a pulse train (DATA_IN) at an oscillation frequency, means (3000) for counting the number of pulses during a fixed period of time independent of a temperature to be measured (T) and for generating a plurality of bits (b 11 , b 10 ,..., b 0 ) indicating the number of pulses in the pulse train (DATA_IN), and means (4000) for generating a serial digital signal (DATA_OUT) from said bits (b 11 , b 10 ,..., b 0 ), in which the means (2000) for generating a pulse train (DATA_IN) include a plurality of logic gates (2410, 2420, 2430, 2440, 2450) which can introduce a delay dependent on the temperature to be measured (T), said means (2000) generating a pulse train (DATA_IN) the oscillation frequency of which is dependent on said temperature to be measured (T). The invention also relates to a temperature measurement method and to a transponder for a wireless system.
