Title: David G. Wright and Stylus Detection Technology.

Introduction

David G. Wright is an inventor associated with Woodinville, Washington, and Wacom Corporation Limited. His patent work addresses touch-controller technology for detecting both finger input and stylus signals.

Latest Patents

Wright is named on one patent: “Stylus Detection System Having Touch Object Detecting Mode and Stylus Detecting Mode.” The invention describes a sense array with crossing lines and a touch controller that operates in two modes. In touch-object mode, the controller drives one set of lines to detect finger input and measures signals on the crossing lines. In stylus mode, it detects a signal transmitted by a stylus across both sets of lines. By using multiple reception channels to sense more than one line at a time, the system can reduce scanning time compared with scanning all lines through a single channel. Wright’s listed portfolio includes 1 patent.

Career Highlights

Wright’s documented patent contribution focuses on improving the efficiency of stylus detection in touch-sensing systems. The patent describes a method for completing a stylus scan in fewer total scans by using multiple reception channels.

Collaborations

The patent lists Andriy Ryshtun and Viktor Kremin among Wright’s coworkers. The invention is associated with Wacom Corporation Limited, a company known for digital pen and touch technologies.

Conclusion

David G. Wright’s patent work highlights a practical approach to faster stylus detection by combining touch-controller modes with parallel signal sensing.
