A new seismic isolation system, TAMA Seismic Attenuation System (TAMA-SAS), was installed to TAMA300 in order to improve the sensitivity at low frequencies. Inertial damping is one of the hierarchical control systems of the TAMA-SAS which are employed to give full play to its ability. We have established two servo loops to control the Inverted Pendulum (IP) which composes the SAS. One is the se...

This paper addresses the recent development of real-time visual odometry system based on a dual optical-flow system and its integration to an inertial navigation system aiming for smallscale flying robots. To overcome the unknown depth information in optic-flow, a dual opticflow system is developed and tested. The flow measurements are fused with a low-cost inertial sensor using an extended Kal...

A human tracking system based on the integration of the measurements from an inertial motion capture system and a UWB (Ultra-Wide Band) location system has been developed. On the one hand, the rotational measurements from the inertial system are used to track precisely all limbs of the body of the human. On the other hand, the translational measurements from both systems are combined by three d...

Yu. A. Ryabov and R. D. Driver proved that delay equations with small delays have Lipschitz inertial manifolds. We prove that these manifolds are smooth. In addition, we show that expansion in the small delay can be used to obtain the dynamical system on the inertial manifold. This justifies “post-Newtonian” approximation for delay equations.

Inertial technology has evolved over the last fifty years from one based on iron gyros, with error control from zero velocity updates and star trackers to ring laser and fiberoptic gyros updated with GPS observations of various types. Today, micro electromechanical system (MEMS) inertial measurement units (IMU) are maturing to the state that low-cost commercialization is becoming feasible. At t...

Reliable information about position and attitude is an essential requirement for many applications. The work expounded in this paper aims at a tight integration of low-cost inertial navigation and stereo vision to obtain this information. The method I present here is based on passive measurements and does not rely on external referencing. Thus, it provides a navigation solution for unknown indo...

Although accelerometers are extensively used for assessing gait, limited research has evaluated the concurrent validity of these devices on less predictable walking surfaces or the comparability of different methods used for gravitational acceleration compensation. This study evaluated the concurrent validity of trunk accelerations derived from a tri-axial inertial measurement unit while walkin...
