First Claim
Patent Images
1. A blown fuse indicator circuit comprising:
- a first diode and a first resister comprising a first series;
a second diode and a second resistor comprising a second series;
a fuse disposed between one end of said first series and one end of said second series;
a zener diode and a light emitting diode comprising a third series, said third series connected to an opposing end of said first series; and
an opto-coupler circuit disposed between one end of said third series, an opposing end of said second series and an opposing end of said third series.

Abstract
There is provided a microcontroller for controlling the activation of a hopper, bowl feeder, and linear feeder. There is further provided a blown fuse circuit which indicates that a fuse has blown for the various components of the part feeder system as well as preventing machines at the load from being powered should the fuse blow.

3. A controller for controlling a part feeder system comprising:
-
a microcontroller; a first semiconductor for providing activating power to a bowl feeder; and blown fuse circuitry, said blown fuse circuitry comprising a first diode and a first resister comprising a first series, a second diode and a second resistor comprising a second series, a fuse disposed between one end of said first series and one end of said second series, a zener diode and a light emitting diode comprising a third series, said third series connected to an opposing end of said first series, and an opto-coupler circuit disposed between one end of said third series, an opposing end of said second series and an opposing end of said third series, said blown fuse circuitry preventing voltage from passing to a load when said fuse associated with said load has blown; wherein said microcontroller calculates a phase delay relative to a reference signal for activating said first semiconductor. - View Dependent Claims (4)
