The object of this developed system was for measuring and sorting the PTC(Positive Temperature Co-efficient), which has been widely used in industrial application, especially in the electronics field and in computer engineering.
The other methods measure and sort one PTC in one processing using a
large and heavy steel disk, so that the processing capability is limited to
under 110 PTC per minute.
In addition, it processes only I PTC per processing time and requires a high starting torque motor and large breaking power source to stop.
The proposed development system used a high speed sampling A/D converter and an array processing technique to measure and sort on a light conveyer for a continual processing.
The arrays consisted of 5 arrays, one for measuring and the others for distinguishing the grade. Those were 8 columns and 8 rows that could process 64 PTCs at once, therefore the processing speed was increased up to 8,800 PTCs per I minute.
It was also able to evaluate and distinguish the PTC's performance and grade.
The algoritm in this system employed a temporal parallelism and a spatial parallelism for increasing measurement and sorting.
The proposed processing algorithm on this system was 80 times faster than the other method.
