portable watch with a measure of the radiation, the method of converting the low voltage to high voltage converter and small-sized.mainly for handheld devices.

摘要

the invention relates to a combined personal devices.using the combination of measuring time with simultaneous control of the radial load on the rights and control of radiation.the proposed invention is the use of personal wrist watch as a radiation detector geiger muller counter and the e the work for a long time.to support the work of the meter geiger - muller in wrist watches and other small appliances necessary converter electric voltage from 1.5 to 3 to 400.the task is solved in that the portable clock known as the geiger counter radiation detector used muller.further a pulse voltage converter for the power meter geiger - muller, and the microprocessor is connected with the voltage transducer.the task is solved byin a method of converting low voltage high power in u0440u0430u0437u043cu044bu043au0430u043du0438u0438 key by comparing the voltage threshold element momentum reversal in the primary, wsou043eu0442u043au0435 with preset value, and changing the frequency of pulse front office key depending on the signal to a threshold elementthe impulses of the key received from the microcontroller, and the receiving signal from the meter geiger muller send additional impetus u0443u043fu0440u0430u0432u043bu0435u043du0438 i'm a key switching.the task is solved in that a u043cu0430u043bu043eu0433u0430u0431u0430u0440u0438u0442u043du043eu043c u043fu0440u0435u043eu0431u0440u0430u0437u043eu0432u0430u0442u0435u043bu0435 voltage in the primary coil transformer includes a threshold element, united u043du0435u043du043du044bu0439 with bythe microprocessor is connected with the base data and a field transistor. there are other differences from the prototype.studies have shown that the device ensures a sufficiently high measurement accuracy is ensured, and the work for a long time before 1 year of u043eu0434u043du043eu0433 on the u043cu0438u043au0440u043eu044du043bu0435u043cu0435u043du0442u0430.
