They consist of a central unit, a group of data and control direction bus bars, a group of memories, and a calendar clock, groups of bus bars selectively connected to channel controller stages, associated with input and output adapters, a cathode ray tube controller whose screen visualises the results of the measurements, an indicator for a numerical controller with keypad associated with decoders, a timer associated with a control stage and ultrasound transmitters and receivers, and a controller associated with an analog/digital converter connected to a multiplexer and to amplifiers corresponding to a load cell associated with a support platform for the user, to determine the weight, and a pressure sensor, for determining the blood pressure. After inserting a coin, one obtains their weight, height, blood pressure and temperature. <IMAGE> |
