Filed:

Dec 7, 2005

Appl. No.:

11/295721

Inventors:

Charles William Blevins - Madison AL, US

Assignee:

Smiths Aerospace LLC - Grand Rapids MI

International Classification:

G11C 29/00

US Classification:

714763, 714764, 714767

Abstract:

A system and method for detecting and correcting errors in a memory in a device includes generating an error value of data stored at first predetermined locations in a first memory. The generated error value is compared to a corresponding error value stored in an error memory, each value in the error memory being calculated from at least two data values stored at predetermined locations in the first memory. The data stored in the first predetermined locations of the first memory is rewritten with data stored in first predetermined locations of a second memory if the generated error value is different than the corresponding error value stored in the error memory, the data stored in the second memory being the same as the data stored in the first memory.

Abstract:

A combine performance monitor includes a programmed, special purpose computer coupled to a plurality of sensors for detecting a plurality of different operating conditions in a combine. The special purpose computer cooperates with operator accessible controls for calculating a plurality of predetermined performance parameters of the combine in accordance with signals from the sensors. The computer is further responsive to actuation of the controls by the operator for modifying the program so as to customize the combine performance monitor for operation with any combine selected, for operation with the particular sensors utilized in that combine selected and for operation of the selected sensors and combine in harvesting a particular grain.
