Appeal No. 95-2925
Application 08/162,820
The invention pertains to an apparatus and method of monitoring engine parameters.
Claim 10 is illustrative and reads as follows:
10. An apparatus for monitoring a plurality of different parameters related to the
operating condition of an engine powered device, comprising:
a plurality of sensors each sensing a different one of the plurality of operating parameters
of the engine powered device and each producing a parameter signal representative of the
parameter being sensed;
processor means for receiving said parameter signals, processing each of said parameter
signals and determining which ones of the parameter signals are at an undesirable operating
condition, classifying each parameter signal having an undesirable operating condition into one of
a preselected number of warning levels with respect to the severity of said undesirable operating
condition, selecting those classified parameter signals being at the highest warning level, and
producing a sequence of individual display control signals at spaced time intervals of those
parameter signals having the highest warning level, each display control signal of the sequence of
display control signals being related to a particular one of only the classified parameters having
the highest warning level; and
a first display having a plurality of selectively energizable segments arranged in a
preselected pattern and being connected to said processor means, said first display receiving said
sequence of display control signals and energizing a selected one of said plurality of segments
corresponding to the individual display signal being received at that time in the sequence and
visually indicating the magnitude of the individual sensed parameter.
