Title: Innovations by Barry W Mullins
Introduction
Barry W Mullins is an accomplished inventor based in Glendora, CA. He holds 2 patents that showcase his innovative contributions to the field of keyboard technology. His work focuses on enhancing the functionality and efficiency of keyboard switches.
Latest Patents
One of his notable inventions is the Low Profile Keyboard Switch. This capacitance keyboard switch features significantly reduced vertical dimensions, allowing for a more compact keyboard design. The switch has an overall height of only 0.750 inches (19.05 mm) and a travel length of up to 0.150 inches (3.81 mm). This innovation eliminates the need for a housing by utilizing a plunger-snap-in guide combination and a single sheet movable capacitor plate that interacts with a plate on the printed circuit board. The entire assembly is designed to be mounted and supported on the printed circuit board, with components snapped together without the need for separate hardware.
Another significant patent is the Capacitive Key for Keyboard. In this design, an operator depresses a plunger that alters the separation between the plates of a capacitor, changing its capacitance. The invention includes a portion of the movable capacitor plate formed into a spring, allowing for overtravel of the plunger after the capacitor has been altered. This feature enhances the user experience by providing additional feedback during operation.
