–Wireless Mesh Sensor Networks are being deployed today in various monitoring and control applications. Some radio network designs, such as ZigBee, presume that radio connectivity is reasonably consistent over time. Others take the opposite approach of presuming that links are entirely unreliable, and build large degrees of physical redundancy into the(More)
In collaboration under a Department of Energy grant for the Industries of the Future, General Electric and Sensicast Systems have studied performance of 2.4 GHz IEEE 802.15.4 radio transceivers in factory environments, with particular attention to jamming from 802.11 and multipath fading. Temporal and frequency variations in link quality are explored. The(More)
The goal of the Federated Intelligent Product Environment (FIPER) is to form a federation of distributed services that provide engineering data, applications and tools on a network. A highly flexible software architecture has been developed,in which engineering tools like computer-aided design (CAD), computer-aided engineering (CAE), product data management(More)
This paper introduces a compact, wireless, wearable system that measures signals indicative of forces, torques and other descriptive and evaluative features that the human body undergoes during bursts of extreme physical activity (such as during athletic performance). Standard approaches leverage highspeed camera systems, which need significant(More)
In this paper, we overview recent work from our research group that explores two very different applications of wearable inertial systems. The first project exploits an array of wearable, ultrawide-range, synchronous IMUs to measure the performance of professional baseball players. We describe some special aspects of our hardware (a dual-range, 6-DOF IMU(More)
Fusion of 6 Dimensional Sensor Data using Physics Engines Capture of high speed athletic motion has until now only been possible by using expensive high speed camera systems. This work presents a novel alternative in form of a wireless inertial measurement system. The sensor data from this system is combined using a physics engine andallows a higher(More)
