Title: John M Ingram: Innovator in Switch Matrix Technology
Introduction
John M Ingram is a notable inventor based in Sacramento, CA. He holds a total of 3 patents that showcase his expertise in switch matrix technology. His innovative approaches have contributed significantly to the field of electrical engineering.
Latest Patents
One of his latest patents is a "Method for testing switch matrices." This testing method involves connecting a first group of input conductors to output conductors. The process sums the number of switching devices connected to each output conductor at intersections with the input conductors. The output conductor with the least number of switching devices is selected, and the switching devices are summed for each input conductor that intersects with the chosen output conductor. The input conductor with the least number of switching devices is then selected for closure to establish the first connection in the desired output combination. This process continues until all connections are made or a failure occurs.
Another significant patent is "Switch matrices using reduced number of switching devices for signal." This invention includes a switch matrix with multiple rows of input conductors and columns of output conductors. The switching devices are programmable, allowing for flexible connections between input and output conductors. The arrangement of the switching devices is random, enhancing the versatility of the switch matrix.
