Constraint singularities of parallel mechanisms
Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003The concept of constraint singularity is introduced. This is a phenomenon occurring in parallel mechanisms with reduced freedoms when the screw system, formed by the constraint wrenches in all legs, loses rank.

A Parallel Computer Organization and Mechanizations
IEEE Transactions on Electronic Computers, 1963This paper describes a type of parallel computer organization which can be regarded as lying at one extreme of a spectrum of possible degrees of parallelism. The organization is dominated by two characteristics, namely, one-bit storage per computational cell and single-level logic at each computational step.

A Parallel Mechanism for Describing Silhouettes
IEEE Transactions on Computers, 1972We describe a parallel mechanism, based on an array of circularly nutating photodetectors, that computes an approximation of the density of slopes of the boundary of any piecewise regular silhouette. This density, when properly normalized, is invariant with respect to the size, translation, and orientation of the given silhouette.

Parallel replacement mechanism for multithread
Proceedings. Advances in Parallel and Distributed Computing, 2002This paper presents a new rapid thread replacement mechanism which is important in multithread technology. Analysis to the memory system indicates that the memory utilization decreases with the increase of cache hit ratio. The parallelism between thread computation and thread replacement is found by analyzing their working processes. Based on these, we

A Soft Parallel Kinematic Mechanism
Soft Robotics, 2017Abstract In this article, we describe a novel holonomic soft robotic structure based on a parallel kinematic mechanism. The design is based on the Stewart platform, which uses six sensors and actuators to achieve full six-degree-of-freedom motion.

Coordinate measuring machine with parallel mechanisms
Computer Standards & Interfaces, 1999Widely used in manufacturing industry, coordinate measuring machines(CMM) are traditionally designed with a serial structure, which is composed of a serial chain of three mutually perpendicular prismatic joints to achieve three degrees of freedom in motion.
