AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1, 3, 4, 7, 9, 10 and 12-14 is confirmed.
Claims 2, 5-6, 8 and 11 were not reexamined.
1. Arrangement for actuating two or more actuator devices from a single microprocessor output, comprising
a microprocessor control element having an input terminal and an output terminal, said output terminal providing a signal which is high, low, or intermittent depending on an input signal applied at said microprocessor input terminal;
a switch device having a control input coupled to the output terminal of said microprocessor control element, a first current carrying electrode connected to a current sink, and a second current carrying electrode;
a first relay actuator coil for actuating one of said devices, and having a first end connected to a voltage supply and a second end connected to the second current carrying electrode of said switch device;
a first capacitor having a first terminal connected to the first end of said first relay actuator coil, and a second terminal;
a one-way current conducting device having a first electrode connected to the second electrode of said first relay actuator coil and a second electrode connected to the second terminal of said first capacitor;
a second relay actuator coil for actuating a second one of said devices, and having a first end connected to the first terminal of said capacitor and a second end; and
a negative resistance device having a first end connected to the second terminal of said first capacitor and a second end connected to the second end of said second relay actuator coil.
