Saving portable computer battery power through remote process execution

Battery charge saving in wireless image sensors for remote metering

The paper presents a methodology to reduce the energy consumption of visual sensor node in wireless sensor networks. This methodology, based on a balancing between processing and transmission tasks, can be applied in all those situations where subjective image based measurements are required. Considering that in a sensor node, the transmission task is the most energy consumption, the proposed m...

Damage Dosimeter: A Portable Battery Powered Data Acquisition Computer

The Damage Dosimeter has been designed to fill a void in commercially available data recorders. The United States Air Force often has the need to measure structural strains and temperatures on in-service aircraft in order to diagnose difficult-to-analyze structural conditions, such as high cycle fatigue. To perform these functions a rugged, small, and lightweight data acquisition unit called th...

Design Considerations and Advances in Portable Power Battery Chargers

Battery-charger demands have changed from a simple stand-alone charger to an embedded charger and power source for the system. This topic provides some insight into the many new issues the designer should consider when designing either a linear or a switching regulator. Common transient issues caused by hot plugging/unplugging the adapter or system load during operation are presented. Problems ...

Remote Robot Execution through WWW Simulation

Nowadays, every industry's goal is to improve their manufacturing processes and to increase their cadence of production, in order to be competitive. This goal usually implies a higher automation level (i.e. an increase on the number of robots used in the production chain) and also a more eficient use of the existing robots. This paper shows the state of art on teleoperation and simulation syste...
