Joint Line Changes After Navigation-Assisted Mobile-Bearing TKA
Orthopedics, 2009The purpose of this study was to analyze the clinical results of patients who underwent navigation-assisted cruciate ligament retention-type mobile-bearing total knee arthroplasty (TKA) according to joint line changes. From September 2004 to January 2006, cruciate ligament retention-type mobile-bearing TKAs were performed using a navigation system ...

2020 American Control Conference (ACC), 2020
This paper presents a decentralized navigation system, capable of estimating positions and fluid velocities, for vehicle formations. Some vehicles have access to a measurement of their own position while the others have access to one or more bearing measurements and may have a depth measurement.

Computer Navigation: Improving Outcomes with Hard on Hard Bearings
2007The design and manufacture of ceramic implants has improved significantly over the last decade. Consequently the use of ceramic-on-ceramic bearings in total hip replacement has become increasingly popular with over 150,000 components having been implanted in Europe [1].

Observability Criteria and Unobservable Maneuvers for In-Orbit Bearings-Only Navigation
Journal of Guidance, Control, and Dynamics, 2014This paper provides an analytical derivation of the observability conditions for in-orbit bearings-only navigation that can also be used to solve for the conditions under which unobservable maneuvers occur. The derivation is performed in a rigorous yet relatively simple manner by attempting to solve for the initial conditions in a discrete formulation ...

A Navigation system of mobile robot based on bearing measurements of beacons
2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017The problem of navigation and control of movement of wheeled mobile robot by bearing of the reference beacons is considered. The quality criteria of controllable motion of such robots are revealed, the formalism of nonholonomic mechanics used for constructing their mathematical models is briefly considered.

A Reverse Bearings Only Target Motion Analysis for Autonomous Underwater Vehicle Navigation
IEEE Transactions on Mobile Computing, 2019We present a non-linear navigation solution, referred to as the Reverse Bearing Only Target Motion Analysis (Reverse BO-TMA). Reverse BO-TMA is a passive method for the self-localization of an Autonomous Underwater Vehicle (AUV). Our method relies solely on bearing measurements based on the radiated noise of a passing vessel sailing along a known route.

Navigated lower limb axis measurements: Influence of mechanical weight‐bearing simulation
Journal of Orthopaedic Research, 2007AbstractSuccessful outcomes following high tibial osteotomy (HTO) require precise realignment of the mechanical axis of the lower extremity. The inability to accurately assess the weight‐bearing axis intraoperatively may account for inappropriate degrees of correction with the osteotomy.

A Spherical Coordinate Parametrization for an In-Orbit Bearings-Only Navigation Filter
2013In-orbit rendezvous is a key enabling technology for many space missions. Implementing it employing only bearing measurements would simplify the relative navigation hardware currently required, increasing robustness and reliability by reducing complexity, launch mass and cost.

2007 46th IEEE Conference on Decision and Control, 2007
The problem of guiding an underactuated ship to a particular position and heading is considered. A common approach to motion planning of robots and vehicles involves finding suitable trajectories for the positions of each configuration variable, and then using feedback to regulate the system to these trajectories.

Track initiation of bearings-only tracking based on ant navigation concept
Communications in Nonlinear Science and Numerical Simulation, 2010Abstract A novel heuristic track initiation method is developed for the bearing-only multi-sensor–multi-target tracking system, in which each target is assumed to move with a straight line. The key idea of the proposed method is derived from the ant navigation concept in its foraging life, which differs from the traditional ant colony optimization ...
