VivoSim is an optional software product that aids understanding by displaying an accurate 3-D model of the joint components and the multi-fiber ligament model as they move in space. The UI software provides one-click copying of setup and programming between stations for situations where the same test protocol is to be run on multiple stations.

#MULTI SPEED ETHERNET TESTING PATENT WINDOWS#

The VIVO™ user interface runs on a separate Windows computer host. The stations operate independently of each other. Based on modern control theory, this feed-forward, self-tuning frequency-domain implementation requires less user configuration than ever before, yet provides the best stability and fastest convergence available in any AMTI simulator.Ĭapable of performing short-term kinematic and long-term durability evaluations, VIVO™ is a configurable system that may have from one to three joint test stations in a single frame. VIVO™ has a new, patent-pending iterative learning control system to improve the accuracy of the actual forces and positions generated by the simulator. It relaxes the level of accuracy required when mounting joint specimens in the adapters that hold them in the machine. This capability accommodates mounting variations in the experimental setup. VIVO™ can sense how the joint or implant is placed in the workspace and relocate the coordinate origin in software to match the installed pose of the joint. The virtual coordinate system is also the key enabling element in VIVO™’s exclusive new test setup system.

The user commands forces and motions with respect to software-defined joint-referenced axes, making it unnecessary to consider the complex, pose-dependent, compound-rotation kinematics of the machine’s physical actuators.

#MULTI SPEED ETHERNET TESTING PATENT ISO#

VIVO™ is the world’s first simulator to fully support the Grood and Suntay joint coordinate system, accepted by ASTM, ISO and ISB as a standard for biomechanics joint testing. An independently-specified heuristic constraint model is available for every axis of the VIVO™ that is in force-control mode. Upward-compatible with the soft tissue model used in our older simulators, in VIVO™ the heuristic constraint model has been enhanced and extended with greater flexibility and programmability. VIVO™ also offers our patented heuristic constraint model. This major advance in soft tissue modeling capabilities opens new doors in research and equips VIVO™ to handle anticipated future test specifications. VIVO™ introduces AMTI’s exclusive, patent-pending multi-fiber ligament model, which can capture the 6-DOF inter-axis coupling typical of biological soft tissue systems. VIVO™ supports two virtual soft tissue models. VIVO™ may be programmed with standard or custom force and motion profiles, supporting research and test protocols that range from standard activities of daily living (ADL) tests through extreme sports and even simulation of accidental conditions and injurious activities. VIVO™ provides accurate robotic joint motion simulation for knee, hip, shoulder, temporomandibular, elbow, ankle and spinal joint motions. *specifications subject to change without notice

Optional VivoSim visualization software – provides an accurately scaled real-time display of the Vivo machine, the component under test, and the multi-fiber ligament model.

One to three independently programmable test stations in a single frame – reduces capital acquisition cost, floor space requirement and power connections.

Temperature-controlled serum circulation and containment system.

Iterative learning control – advanced feed-forward control system provides stability and rapid convergence to command during cyclic testing.

User-defined coordinates – change coordinate system origin and orientation to accommodate test specimens as mounted.

Grood and Suntay coordinate system – kinematics are described using joint-referenced virtualized axes.

Traditional heuristic soft tissue model also supported.

AMTI’s exclusive multi-fiber ligament model – captures 6-DOF soft tissue inter-axis coupling.

Convenient user programming of force and motion profiles.

Each axis may operate in force or position control – including zero-force control to simulate an unconstrained axis.

Six degrees of freedom – all joint motions can be controlled and measured.VIVO™ provides the world’s first full-speed, full-load six degree of freedom environment in which to test joint prostheses as well as biological joint specimens. AMTI’s VIVO™ brings new life to joint motion simulation, dramatically increasing the kinetic and kinematic realism of simulation to provide the closest possible approach to in-vivo conditions.
