TL;DR: In this article, a system using a PENDULOUS, INTEGRATING, GYROSCOPE ACCELEROMETER ROTATED about its GRAVITY AXIS, in a level plane on the Earth is described.
Abstract: A SYSTEM USING A PENDULOUS, INTEGRATING, GYROSCOPE ACCELEROMETER ROTATED ABOUT ITS GRAVITY AXIS, IN A LEVEL PLANE ON THE EARTH. THE ROTATION VELOCITY OF THE EARTH CAUSE THE PENDULOUS MASS TO EXERT A VARYING PRECESSIONAL FORCE ON THE GYROSCOPE. THE FORCE IS DETECTED AND CORRELATED WITH THE ANGULAR POSITION OF THE ACCELEROMETER TO DETERMINE NORTH.

TL;DR: In this paper, a power steering system consisting of an electric motor and an input shaft fixed to a steering wheel, an output shaft coupled to the motor via a reduction gear, and a torsion bar provided between the input and output shafts, the output shaft being rotatable by the resultant of a manual torque for rotating the wheel and the torque of the motor.
Abstract: A power steering system having an electric motor and including an input shaft fixed to a steering wheel, an output shaft coupled to the motor via a reduction gear, and a torsion bar provided between the input and output shafts, the output shaft being rotatable by the resultant of a manual torque for rotating the wheel and the torque of the motor. The system comprises a sensor for detecting the relative angular displacement between the input shaft and the output shaft, and a microcomputer having stored therein the relationship between the relative angular displacement and the motor current target value for determining the direction of rotation of the motor and a motor current target value from the output of the sensor to produce outputs. The relationship stored in the microcomputer is a nonlinear relationship wherein variations in the motor current target value with the relative angular displacement are small in the range of small relative angular displacements but are great in the range of great displacements.

TL;DR: An angular position indicator for cranes which uses a combination of electronic, optical and mechanical components is proposed in this article.This indicator is intended for use on fixed or mobile cranes and designed to operate in harsh industrial environments.
Abstract: An angular position indicator for cranes which uses a combination of electronic, optical and mechanical components. It is intended for use on fixed or mobile Cranes and designed to operate in harsh industrial environments. Wireless communication replaces fixed electrical hardwiring that would otherwise be required between system components. The angular position indicator uses an angular displacement transducer of unique design. The angular position indicator performs pattern recognition of optical apertures using analog measurements of the illumination of optical detectors. The design allows for a substantial increase in measurement resolution as compared to digital optical encoders with the same number of optical channels.
