Title: The Innovations of Donald E. Cole

Introduction

Donald E. Cole is a notable inventor based in Covina, CA (US), recognized for his contributions to the field of sensor systems and autopilot technology. With a total of 2 patents, Cole has made significant advancements that enhance the performance and efficiency of airframe navigation systems.

Latest Patents

One of Cole's latest patents is the "Body Referenced Gimballed Sensor System." This innovative system is designed for proportionally navigating an airframe to a target. It utilizes an onboard flight control system that includes body rate gyros to detect the movement of the airframe relative to a fixed reference. The target sensor is mounted for pivotal movement in the pitch and yaw planes on a gimbal assembly that is rigidly connected to the airframe body. Mechanisms such as motor/tachometer/potentiometer assemblies pivot the sensor and provide signals that represent the angular rate of motion and angular position of the sensor. These signals, along with the sensor output, are utilized in a gimbal track loop for tracking the target. The system effectively eliminates the need for a costly and complex space-stabilized gimballed sensor while offering improved performance over a system that utilizes a pure body-fixed sensor.

Another significant invention by Cole is the "Rolling Airframe Autopilot." This autopilot incorporates a single linear accelerometer transducer and a single pitch rate sensor. The outputs of these sensors are summed with the command signal in the control circuit. A servo is then controlled by the modified control signal to vary the incidence of a single plane control system in an intentionally rolling airframe. This innovation simplifies the autopilot design while maintaining functionality.
