With a total of two patents to his name, Charles has demonstrated his expertise in developing innovative solutions that enhance testing processes in various applications.

Latest Patents

One of Larry L. Charles's latest patents is an "Automatic Test System Utilizing Interchangeable Test Devices." This invention describes an automatic test system controlled by a general-purpose digital central processor. The central processor accepts test programs in a high-level compiler language such as Atlas. The Atlas program is compacted into a simplified language that communicates with test devices via a standard IEEE 488 data bus. Each test device includes a programmable interface digital processor that performs necessary translations to allow specific test instruments to conduct tests as specified by the high-level test programs. A switching matrix also communicates with the digital processor to connect the appropriate test device to the unit under test.

Another significant patent by Charles is the "Core Memory Interface for Coupling a Processor to a Memory." This interface circuit couples a digital processor to a core memory, accepting address signals, data signals, and control signals from the processor. The output consists of control signals to manage the memory and a parallel digital data word having 2N bits, where N is the number of parallel bits transferred by the digital processor. The process involves transferring a digital data word to a buffer memory before executing store and read instructions, requiring two instructions for both storing and reading data from the core memory.
