Latest Patents
One of Da Y Wang's notable recent patents is related to an *exhaust gas sensor diagnostic*. This innovative diagnostic apparatus utilizes electrochemical polarographic principles to assess the functionality of internal combustion engine exhaust gas sensors. It effectively determines the sensor's operational status within a current-limiting region by monitoring sensor output signals that reflect oxygen concentration in the exhaust gas. The system strategically perturbs a sensor drive signal, allowing for a detailed observation of sensor sensitivity in response to disturbance. The diagnostic indicates potential current limiting conditions based on sensor insensitivity to perturbation.
Another significant patent from Wang is the *starting circuit for a high-intensity discharge lamp*. This invention involves a sophisticated starting circuit that works in conjunction with a high-intensity discharge lamp equipped with electrodes. In this design, an inductor is placed in series with the lamp's electrodes, and a first switching transistor is coupled in series with a diode and a load resistor. This configuration enables the inductor to charge when the first transistor is activated, subsequently discharging energy as a voltage pulse across the lamp when switched off. This ingenious mechanism enhances the efficiency and performance of high-intensity lighting applications.
