Latest Patents

One of Hall's latest patents is a method and apparatus for determining a value of a variable parameter. This invention provides a control methodology and apparatus for engines suitable for use in capacitor discharge ignition systems for internal combustion engines or brushless DC motors. The system utilizes a simple logic block to determine ignition timing advance angles or duty cycle signals based on actual engine speed versus stored engine control parameter data. To optimize memory usage, a limited number of values are stored, and the logic block employs linear interpolation to determine the required engine control signal.

Another significant patent is an ignition control device that features both an Electronic Fuel Injection (EFI) mode and a Capacitive Discharge Ignition (CDI) mode. This device includes an output for providing voltage to a load, which can be either a fuel injection actuator or an ignition capacitor. The driver unit within the device manages the output voltage transitions, with specific timing adjustments based on the mode selected.
