Title: Innovations of Yam C Leung
Introduction
Yam C Leung is an accomplished inventor based in Bloomingdale, Illinois. He holds two patents that showcase his expertise in engine diagnostics and automation. His contributions to the field have significantly advanced the technology used in internal combustion engines.
Latest Patents
One of his latest patents is the "Engine Test and Display Apparatus." This invention describes an improved automated engine diagnosing device that employs a digital data processor computer and a cathode ray tube display monitor. The monitor displays engine parameter values in alphabetic, numeric, and graphical form. Some data is accumulated from the engine through direct digital measurements, while other data is obtained via an analog-to-digital converter. The processed data is then displayed on the cathode ray tube monitor, enhancing the diagnostic capabilities of the device.
Another notable patent is the "Signal Disabling Engine Diagnosing Apparatus." This invention describes apparatus for disabling selected cylinders of an internal combustion engine operated by periodic cycles of ignition signals. The apparatus prevents one or more predetermined ignition signals in each cycle from energizing engine components, such as spark plugs. A clock pulse generator generates a uniform pulse in response to each ignition signal, and bistable flip-flop circuits produce output signals representative of the number of clock pulses received. This innovative approach aids in the diagnosis of the engine by selectively disabling ignition signals.
