A method of manufacturing an article including taking an article in an initial state formed using an additive manufacturing process, the article including at least one set of mounting features; performing a second manufacturing process to transform the article into a second state, which includes mounting, via the at least one set of mounting features, the article in a holding device of a machine for operating on the article, wherein the position and orientation of the article in three linear and three rotational degrees of freedom within the machine operating volume is known and defined by virtue of the interaction of the mounting features with the holding device, and processing at least one feature on the article. The at least one mounting feature includes kinematic mount features which engage with corresponding kinematic mount features on the holding device of the machine..
System and providing information on fuel savings, safe operation, and maintenance by real-time predictive monitoring and predictive controlling of aerodynamic and hydrodynamic environmental internal/external forces, hull stresses, motion with six degrees of freedom, and the location of marine structure
A system for monitoring a physical change of a marine structure includes a complex optical measuring instrument configured to detect a behavior and structural change of the marine structure by using at least one optical sensor by means of optical fiber bragg grating.. .
Bending and twisting mechanism and its applications to robotics and energy conversion
A mechanism includes at least one module (m1) having a tubular structure with at least three faces, each of said faces comprising: two parallel longitudinal fibers (1, 4), rigid and inextensible, whose ends are connected through respective ball or elastic joints (0-1; 4-0) to the ends of the fibers of contiguous modules, or to a base (0); a transverse link (2) connecting said two longitudinal fibers, having a first end rigidly connected to said first fiber and a second end slidably connected to said second fiber, said transverse link being inextensible and having two rotational degrees of freedom; a longitudinal link (32) connecting said transverse link to a homologous transverse link of an adjacent module or to a base via a ball or elastic joint (32-0) and an universal joint (3-32); and an actuator (a) for changing the length of said longitudinal link.. .
Intracardiac imaging system utilizing a multipurpose catheter
A three dimensional physiological mapping system utilizing an intracardiac echo catheter capable of being located in six degrees of freedom by a visualization, navigation, or mapping system. An echocardiography image of the intracardiac echo catheter may be projected within a geometric model of the visualization, navigation, or mapping system where the location of the projected image is adjusted in response to user input identifying a structure present in the echocardiography image and the geometric model..

Steady hand micromanipulation robot
A cooperative-control robot includes a base component, a mobile platform arranged proximate the base component, a translation assembly operatively connected to the base component and the mobile platform and configured to move the mobile platform with translational degrees of freedom substantially without rotation with respect to said the component, a tool assembly connected to the mobile platform, and a control system configured to communicate with the translation assembly to control motion of the mobile platform in response to forces by a user applied to at least a portion of the cooperative-control robot. The translation assembly includes at least three independently operable actuator arms, each connected to a separate position of the mobile platform.

Operating machine with redundant axes and resolution of the redundancy in real time
A program for a numerical control device is disclosed that determines path points to be approached by an end effector. A control signal group is ascertained for each path point that contains its set point value for each position-controlled axis.
Expandable interbody fusion device
An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded.
