Energy-Efficient Continuous Activity Recognition on Mobile Phones: An Activity-Adaptive Approach

Karl Aberer, Zhixian Yan, Dipanjan Chakraborty

Power consumption on mobile phones is a painful obstacle towards adoption of continuous sensing driven applications, e.g., continuously inferring individual’s locomotive activities (such as ‘sit’, ‘stand’ or ‘walk’) using the embedded accelerometer sensor. ...

Progress Towards a Miniaturized Electrospray Thruster for Propulsion of Small Spacecraft

Herbert Shea, Caglar Ataman, Simon Dandavino, Subha Chakraborty

Miniaturized electrical thrusters based on electrospray (or colloid) emitters could rev- olutionize the spacecraft industry by providing efficient propulsion capabilities to micro and nano satellites (1-100 kg). We report on our recent advances in the deve ...

Long-term mechanical reliability of ceramic thick-film circuits and mechanical sensors under static load

Peter Ryser, Thomas Maeder, Caroline Jacq

In this work, we study the long-term mechanical strength under static load - i.e. static fatigue performance or resistance to subcritical crack growth - of ceramic thick-film circuits, namely how the static fatigue of the substrate is affected by the prese ...

Passive Phase Noise Cancellation Scheme

Luis Guillermo Villanueva Torrijo

We introduce a new method for reducing phase noise in oscillators, thereby improving their frequency precision. The noise reduction is realized by a passive device consisting of a pair of coupled nonlinear resonating elements that are driven parametrically ...

The thermodynamics of devices with solid layered-bed magnetocaloric refrigerants

Didier Albert Simon Vuarnoz, Gilles Courret

In conventional refrigeration the use of the T S diagram to determine thermodynamic cycle performance is a well accepted tool. This method is based on a single state description of the gaseous refrigerant during its cycling. Devices filled with a magnetoca ...

Platform-wide Deadlock Immunity for Mobile Phones

George Candea, Horatiu Jula, Thomas Rensch

We present an implementation of our deadlock immunity system, Dimmunix, for mobile phone software. Within Android 2.2 OS, we modiﬁed Dalvik VM, the JVM running all the Android applications, to provide platform-wide deadlock immunity. We successfully ran th ...

Cooperative video streaming on smartphones

Christina Fragouli, Lorenzo Keller

Video applications are increasingly popular over smartphones. However, in current cellular systems, the downlink data rate fluctuates and the loss rate can be quite high. We are interested in the scenario where a group of smartphone users, within proximity ...

Making Mobile Augmented Reality A Reality

Jeffrey Huang, Hendrik Ole Knoche, Laurent Bindschaedler

Recent advances in mobile device technology have freed augmented reality (AR) applications from the constraints of desktops, laptops and head-mounted displays. But they are met with a lack of guidelines on the design and user interactions of mobile device- ...
