Latest Patents

One of Armitage's latest patents is a "Computer program architecture for onboard vehicle diagnostic system." This invention includes a variety of monitor modules designed to oversee vehicle systems or components. Upon detecting a malfunction, these modules issue a subroutine call to a diagnostic executive. The executive comprises several software objects that manage malfunction indicator light control and fault code storage strategies. Additionally, a diagnostic scheduler module, implemented as a finite state machine, coordinates the sequence of tests run by the monitor modules and conducts on-demand self-tests. The malfunction indicator light control module employs four distinct strategies for managing the light and handling fault codes under specific conditions.

Another significant patent is the "Method and apparatus for inferring barometric pressure surrounding an internal combustion engine." This invention provides a mass airflow-based control system capable of inferring the barometric pressure around the engine. The control system assesses the air charge entering the engine based on measured mass airflow and compares it to a predicted value. Any discrepancies are first attributed to the measured inlet air temperature and subsequently to changes in barometric pressure.
