Title: David V. Adams and His Patented Drive and Control Technologies.

Introduction

David V. Adams is an inventor associated with San Carlos, California, and Acuson Corporation. His work includes patented technologies for converting manual input into electrical signals and for controlling rotary drive systems. The supplied information lists 2 patents for Adams.

Latest Patents

Adams’s listed patents address control and motion in electromechanical systems.

- **Bi-directional hall-effect control device.** This device converts manual input into an electrical signal. A pivoting control button carries two magnets with opposite polarities, while a nearby Hall-effect sensor detects the button’s movement. The resulting signal can be used, for example, to control the velocity of a motor that rotates an ultrasound transducer.

- **Drive system with a multiturn rotary stop.** This drive system couples a motor to a rotary stop through a spring stop assembly. A motor-driven gear connects to a hub by a torsional spring, and the system may include a position encoder and a drive shaft. The arrangement is designed to drive a rotatable load while providing a multiturn rotary stop.

Career Highlights

Adams’s listed inventions reflect work on practical mechanisms for controlling motorized equipment. His Hall-effect control device translates a user’s physical input into an electrical control signal, while his rotary-stop drive system combines gearing and a torsional spring to manage motion and positioning. The supplied information associates his work with Acuson Corporation.
