Latest Patents

One of Aguinaga's latest patents is a fuel sensor designed to determine properties of fuel, such as gasoline and ethanol blends known as flex fuel. This sensing apparatus features an acetal plastic tube with an inlet, an outlet, and a fuel passage in between. It measures the dielectric constant of the fuel, utilizing a pair of sensing plates positioned on opposite sides of the tube. A processing circuit on a printed circuit board (PCB) is connected to the sensing plates, applying an excitation signal to sense capacitance and generate an output signal indicative of the fuel's properties. The design includes a shield to reduce electromagnetic interference (EMI) and an interface connector for outputting the capacitance signal to an engine controller.

Another significant patent involves a control routine for a current driver. This method and apparatus control a solenoid-actuated charcoal canister purge valve, regulating the flow of purge fuel to an internal combustion engine's cylinder. The process includes generating a preselected input duty cycle for energizing the purge valve, which is monitored by a microcontroller. The system measures feedback voltage from the valve, allowing the microcontroller to calculate errors and generate a compensated output duty cycle to ensure optimal performance.
