Latest Patents

Morris's latest patents include a method for controlling ground bounce above an internal ground plane in a circuit board test fixture. This innovative algorithm selects probe locations for both test signal probes and ground probes, minimizing ground bounce during testing. The algorithm operates by superimposing an imaginary grid of squares over the circuit board, ensuring that no more than five test signal probes for each ground probe reside within each square. Additionally, it guarantees that each critical test signal probe is associated within a preselected distance of a ground probe. In the preferred embodiment, the imaginary squares measure 1.4 inches on a side, with a preselected distance of approximately one inch.

Another notable patent by Morris is a method for regenerating in-circuit test sequences for circuit boards. This method automatically determines which test sequences need to be regenerated due to board modifications and efficiently regenerates only the affected sequences.
