Title: Discovering the Innovations of Tommy D Hollingsworth

Introduction

Tommy D Hollingsworth, a prolific inventor based in Leander, Texas, holds five patents that showcase his contributions to the field of technology. With a focus on enhancing electronic devices and systems, his inventions have implications in various applications, particularly in touch-sensitive interfaces and electrostatic discharge (ESD) protection.

Latest Patents

One of Hollingsworth's most significant inventions is the electric field proximity keyboards and detection systems. This invention revolves around a detection system that uses an electric field suitable for touch-sensitive keyboards or close proximity operations without requiring direct contact. The design employs an AC signal coupled to an electrode acting as an antenna to radiate the electric field. A conductive object nearby disrupts this field, resulting in a voltage change that can be detected, signalling the presence of the object. Hollingsworth's design allows for multiple electrodes to be controlled through an analog multiplexer, enhancing resolution while maintaining simplicity. These circuits can also be integrated into semiconductors, reducing both size and cost, with applications that extend to remote sensing, motion detection, and remote controls.

Another notable patent involves the development of an electrostatic discharge mitigation structure, utilizing a dissipative capacitor with voltage-dependent resistive material. This innovation aims to minimize ESD damage to electronic devices. The structure features a parallel plate dissipative capacitor with a dielectric layer formed from a nonconductive dielectric combined with a voltage-dependent resistive material. This design effectively dissipates harmful voltages into thermal energy before they can harm sensitive electronics. The dielectric layer returns to its original state once the excess voltage decreases below a specified threshold, allowing the capacitor to function normally. This innovative structure also finds applications in EMI/RFI shielding.
