Title: The Innovative Mind of James A. Kriewall: Pioneering Stylus Technology
Introduction: James A. Kriewall, an accomplished inventor based in Saratoga, California, holds a significant position in the realm of technology with his innovative patent in digitizer systems. His work has contributed to advancing stylus technology, particularly through the utilization of acoustic waves.
Latest Patents: Among James A. Kriewall's notable patent is the "Stylus position digitizer using acoustic waves." This invention involves a sophisticated digitizer that determines the position of a stylus on a plate by utilizing acoustic waves generated from the stylus itself. The acoustic waves are introduced from the tip of the stylus and are intercepted by multiple detectors strategically placed around the plate's perimeter. Through the analysis of arrival time differences of these waves at the detectors, a microprocessor accurately calculates the stylus's position. In particular implementations, employing a non-tethered stylus, four detectors are positioned at the corners of a rectangle, with time differences offering addresses in a lookup table containing corresponding x and y coordinates.
Career Highlights: James A. Kriewall has made significant strides in his career, working with renowned companies like Fujitsu Corporation. His innovative pursuits showcase his commitment to enhancing user interactions with technology.
Collaborations: Throughout his career, Kriewall has collaborated with talented individuals such as Edwin F. Johnson and Alan Robert Selfridge. These collaborations have likely contributed to the depth and effectiveness of his inventive capabilities, creating a lasting impact on the technology sector.
Conclusion: James A. Kriewall's inventive spirit and groundbreaking patent in stylus digitization underscore his contributions to modern technology. His work exemplifies the power of innovation, paving the way for advancements in how users interact with digital platforms. As technology continues to evolve, Kriewall's contributions will remain a testament to the importance of acoustic wave applications in the digitization space.
