Abstract:

An ada tive vote-taker is proposed which compares the outputs of paralleled redundant system parts in a binary system and determines the most probable answer based on past performance of the separate parts. Initially, the vote-taker assigns equal significance to each redundant part, and in a binary system requires that a simple majority of the parts be correct. With experience, the vote-taker continually reduces the weight significance of the outputs from those parts that make mistakes, thereby gradually eliminating the defective parts. Thus, the vote-takers which may also be paralleled if they are unreliable act as automatic repairmen which delete defective parts of a system. System dependability and life expectancy can be made to exceed the dependability and average life expectancy of the component parts. The heart of an adaptive vote-taker is an element providing variable gain with memory. A variable resistor with memory memistor which uses electrochemical depostion or removal of copper to achieve the variable memory was successfully applied to this function. Author
