Title: David A Cowling: Innovator in Control Devices and User Interfaces
Introduction
David A Cowling is a notable inventor based in Bristol, GB. He has made significant contributions to the field of control devices and user interfaces, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Cowling's latest patents is a control device that comprises a reference frame, a stick, a pivot mounting the stick to the reference frame, and an actuator for rotating the stick about the pivot axis. This design achieves mass balance by offsetting the centers of mass of the actuator and the stick from the pivot axis. Typically, a line joining the centers of mass of the actuator and the stick substantially passes through the pivot axis. The actuator is a rotary actuator with a stator coupled to the stick and a rotor coupled to the reference frame.
Another significant patent is for a motor balanced active user interface assembly. This assembly includes a user interface and one or more feedback motors coupled to the user interface. When energized, the feedback motors supply a feedback force to the user interface that opposes user interface movement. One of the feedback motors is positioned such that its center of gravity is located to mass balance the user interface when it is in the null position. This configuration alleviates the need for counterbalance weights.
