Active Vibration Isolation Devices with Inertial Servo Actuators
Cosmic Research, 2018The use of active vibration isolation devices (AVIDs) in aerospace engineering is subject to the following restrictions. First, the volume for installing additional devices is always limited in instrument racks and compartments. Secondly, in many cases, it is impossible to add supports for servo actuators for fundamental or design considerations.

Engineering issues of gridded inertial electrostatic confinement devices
17th IEEE/NPSS Symposium Fusion Engineering (Cat. No.97CH36131), 2002Gridded inertial electrostatic confinement (IEC) systems have shown the successful formation of ion microchannels, with very good ion focusing properties. Nevertheless, major concerns exist about the integrity of the grid due to plasma heating and neutron irradiation. In this study, a hollow tungsten grid, actively cooled by a pressurized water circuit,

Dynamic Characteristic of MEMS Inertial Device by Simulation
Advanced Materials Research, 2012Inertial device is an important part of the fuze system. It is a key mechanism to keep safety at ordinary times and period after launch. Therefore, the dynamic characteristics of the inertial device during falling or launching environments are very important.

Pulsed Operation of Spherical Inertial-Electrostatic Confinement Device
Fusion Technology, 1996Inertial electrostatic confinement (IEC) fusion confines high energy ions in potential wells, where their increased energy and density yields a high fusion rate. Studies of the IEC at the University of Illinois (UI) initially concentrated on steady-state operation where neutron yields of approx.10{sup 6} D-D n/s are routinely obtained.

Navigation by inertial device and signals of opportunity
Signal Processing, 2017Inertial navigation systems are known to yield rather accurate measurements over short time intervals, while their error variance tends to increase with time. In order to keep the error within specification most systems use GPS signals. In the absence of GPS data, due to jamming or spoofing, it is desirable to use signals of opportunity instead.

A prototype wireless inertial-sensing device for measuring toe clearance
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008Tripping and slipping are serious health concerns for the elderly because they result in life threatening injuries i.e., fractures and high medical costs. Our recent work in detection of tripping gait patterns has demonstrated that minimum toe clearance (MTC) is a sensitive falls risk predictor.

Concentration‐controlled particle focusing in spiral elasto‐inertial microfluidic devices
ELECTROPHORESIS, 2017AbstractHerein, we proposed a strategy for controlling the particle focusing position in Dean‐coupled elasto‐inertial flows via adjusting the polymer concentration of viscoelastic fluids. The physics behind the control strategy was then explored and discussed. At high polymer concentrations, the flowing particles could be single‐line focused exactly at

Inertial Properties of an External-Frame Backpack Device
2003Abstract : Previously, an external-frame backpack device (35 kg) was fabricated allowing for the placement of a 24.9-kg lead brick load in nine different positions. The purpose of this report was to determine the moment of inertia (MOI) of the backpack for the nine load positions relative to: the backpack's center of mass (COM); reference axes ...
