Title: The Innovative Contributions of Carl M. Stanchak
Introduction
Carl M. Stanchak is a notable inventor based in Colorado Springs, CO. He holds a total of 9 patents that showcase his expertise in electrical engineering and innovative design. His work has significantly impacted the fields of portable computing and oscillator technology.
Latest Patents
One of Stanchak's latest inventions is the "High Voltage Stylus for Portable Computer." This invention involves a stylus that generates a high-voltage, sinusoidal signal for use with an electrostatic digitizing pad. The high voltage is achieved by applying a sine wave to one lead of the primary of a transformer, while the inverse sine wave is applied to the other lead. The secondary of the transformer produces the high voltage, which is then developed into a signal for the digitizing pad.
Another significant patent is the "Crystal Oscillator with Controlled Duty Cycle." This oscillator circuit features a first node that oscillates with an indeterminate duty cycle and a second node that oscillates with a predetermined duty cycle. Both nodes operate at similar frequencies. A variable current source and a switch are connected in series between Vcc and ground, with the output of the variable current source being the second node. The first node controls the switch, which opens and closes based on the logic state of the first node. This design allows for precise control over the voltage level achieved by the second node during each cycle.
