Latest Patents

Hughson's latest patents include a method for the re-zeroing of a stepper motor without noise or movement. This invention comprises a method and apparatus for driving and homing a stepper motor using 24 micro step pulse width modulated (PWM) voltage signals. The phases between the driving signals are 90° out of phase, employing a sine/cosine methodology to drive the motor. The microprocessor reads stored voltage levels from a table in memory, which corresponds to the desired angular displacement. By reducing the applied voltage to between 15% and 30% of the normal driving voltage, Hughson effectively minimizes the bounce of a pointer attached to the motor's output shaft and reduces noise generated during operation.

Another significant patent is for a self-docking electrical connector designed for drop-in connection of electronic modules, such as audio speaker assemblies. This connector features an electrically insulative body with at least two electrically conductive biasing members. Each biasing member is designed to ensure reliable connections while allowing for resilient deflection, enhancing the overall functionality of electronic devices.
