Abstract A Universal Memory Loader Verifier (UMLV) is disclosed. The loader comprises a system used to load and verify Operational Flight Programs (OFP) into an unlimited number of different types of avionics computers without the need for adding additional hardware (with the exception of an additional cable that may be unique to each particular computer being loaded and verified). The disclosed Universal Memory Loader Verifier (UMLV) consists of a portable, off the shelf, militarized, arm held, battery backed Personal Computer. The PC contains a custom interface card for different types of applications. The PC output is connected to a buffer box having a custom card therein by means of a cable. The buffer box is connected to a single ended driver/receiver type avionics computer through a unique cable. This connection requires an additional cable for each computer type. For all other applications, the PC is connected directly to the avionics computer by means of a unique cable. The Operational Flight Programs for every computer are loaded into the PC RAM memory from a detachable floppy drive, and is maintained in memory by means of a battery.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A universal memory loader verifier for loading and verifying operation flight programs into a number of different types of avionics computers, the combination comprising: a personal computer having a random access memory; a programmable card in said personal computer, said card being programmable for each of said number of different avionics computers; a firmware file for each of said different types of avionics computers, said firmware file programming said programmable card for a particular avionics computer; an operational flight program for each of said different avionics computers; a detachable floppy disk drive for loading one of said firmware files onto said programmable card for programming said card to enable communications between said personal computer and one of said avionics computers; and means for loading said operational flight programs into said personal computer memory, said operational flight program being loaded onto said programmable card for transmission to said avionics computer.
Claim 2
Dependent Claim
149 words
A universal memory loader verifier for loading and verifying operation flight programs into a number of different types of avionics computers, the combination comprising: a personal computer having a random access memory; a programmable card in said personal computer, said card being programmable for each of said number of different avionics computers; a firmware file for each of said different types of avionics computers, said firmware file programming said programmable card for a particular avionics computer; an operational flight program for each of said different avionics computers; a detachable floppy disk drive for loading one of said firmware files onto said programmable card for programming said card to enable communications between said personal computer and one of said avionics computers; and means for loading said operational flight programs into said personal computer memory, said operational flight program being loaded onto said programmable card for transmission to said avionics computer.
Claim 3
Dependent Claim
76 words
