This paper presents analysis of the dynamics and vibration of an orientation motion platform utilizing a sphere actuated by omnidirectional wheels. The purpose of the analysis is to serve as a design tool for the construction of a six-degree-of-freedom motion platform with unlimited rotational motion. The equations of motion are presented taking flexibility of the system into account. The behav...

Platform motion blur is a common problem for airborne and space-based imagers. Photographs taken by hand or from moving vehicles in low-light conditions are also typically blurred. Correcting image motion blur poses a formidable problem since it requires a description of the blur in the form of the point spread function (PSF), which in general is dependent on spatial location within the image. ...

A novel wireless motion sensing device for control of realtime electronics is presented. The device consists of a small (25×40mm) circuit board including all circuitry and battery, and contains a complete inertial measuring unit (IMU), measuring both acceleration and angular velocity in 3 dimensions. Data is transmitted wirelessly via a bluetooth link and can be read from applications either us...

Biomedical implanted sensors will benefit greatly from energy harvesting power sources. Although promising devices have been proposed, system complexity and low power levels have been preventing integration into biomedical wireless sensors. We have proposed a simplified architecture which addresses these critical drawbacks. Here we report a wireless node with increased range (1 meter range) and...

Peningkatan kebutuhan energi dunia relatif mengalami peningkatan yang cukup signifikan dari tahun ke tahun. Kebutuhan akan Energi Baru Terbarukan (EBT) juga meningkat seiring dengan menurunnya cadangan fosil. Ocean Thermal Energy Conversion (OTEC) menajdi salah satu alternatif sumber EBT pengembangan teknologinya berkembang dalam beberapa dekade terakhir. Umumnya OTEC menggunakan barge sebagai ...
