Patent
Driven shielding capacitive proximity sensor
TL;DR: In this article, a capacitive proximity sensing element, backed by a reflector driven at the same voltage as and in phase with the sensor, is used to reflect the field lines away from a grounded robot arm towards an intruding object, thus dramatically increasing the sensor's range and sensitivity.
Patent
Electromagnetic brake/clutch device
TL;DR: In this paper, an electromagnetic brake/clutch device with a plurality of cammed rollers acting to prevent clockwise rotation of the drive shaft and counter-clockwise rotation is described.
Journal ArticleDOI
Capaciflector collision avoidance sensors for robots
TL;DR: The present status of sensor development is described to include the basic workings of the sensor charges and fields, the electronic circuitry and mathematical modeling, and test results are given.
Patent
Spline screw multiple rotations mechanism
TL;DR: In this paper, a system for coupling two bodies together and for transmitting torque from one body to another with mechanical timing and sequencing is presented, where electrical connectors are engaged as long as possible so that the internal processes can be monitored throughout by sensors and electrical and mechanical power and signals are coupled.
Patent
Flex-gear power transmission system for transmitting EMF between sun and ring gears
TL;DR: In this paper, a plurality of flexible cylindrical members, termed flex-gears and having gear tooth type perimeters are located in an annular space between two concentric rotating gear members, one an inner gear member and the other an outer ring gear member.
