Appeal No. 95-3382
Application 07/967,465
Appellants have appealed to the Board from the examiner’s
final rejection of claims 1 to 4, which constitute all the claims
in the application.
Representative claim 1 is reproduced below:
1. A control system comprising:
a plurality of loads;
a drive for each load; and
switch means for operating each drive; characterized by:
means for providing a reference signal with a magnitude that
is a function of a received reference control signal;
means for providing a sense signal indicating total current
through the loads;
means for comparing the sense signal and said reference
signal to produce a reset signal when the sense signal is at
least as great as said reference signal;
means for producing first output signals that activate each
drive simultaneously in response to a first control signal, for
producing second output signals that activate each drive
sequentially in response to a second control signal and for
removing the first output in response to the reset signal;
signal processing means for providing said first control
signal in response to operation of switch means, for providing
said second control signal in response to said reset signal, for
providing said reference control signal in response to said
switch means, for controlling the magnitude of the reference
signal as function of the drives that are operated by the
switches based on stored parameters for each drive, and for
disabling the second signal for a specific drive when the current
to the drive exceeds the value stored for the drive.
The following reference is relied on by the examiner:
