Household equipment process duration determination device - uses automatic process control by involving microprocessor and sensors in time analysis system

摘要

The device has its microprocessor contg. a program to determine the actual time of the work process (dependent on external variables) from the parameters detected by the sensors which detect the external variables and from fixed values used in the program. The microprocessor is connected to a numerical display for the actual time needed for the work process. The actual time needed for the work process is determined at the start of the process and is displayed after the start. Present time is substraced from the needed time until zero is reached.
