Noise levels during nCPAP are flow-dependent but not device-dependent

Objective: Nasal continuous positive airway pressure (nCPAP) has been shown to improve the outcome of infants with respiratory distress syndrome. However, noise generation could be of concern. Therefore, our study was designed to measure the noise levels o ...

Distributed Communication in Swarms of Autonomous Underwater Vehicles

Felix Stephan Schill

Effective communication mechanisms are a key requirement for schools of submersible robots and their meaningful deployment. Large schools of identical submersibles require a fully distributed communication system which scales well and optimises for ”many-t ...

Design of an endoscopic optical reference to be used for autofluorescence bronchoscopy with a commercially available diagnostic autofluorescence endoscopy (DAFE) system

Georges Wagnières, Tanja Gabrecht, Blaise Lovisa, François André Borle

We present the design of a sterilizable optical reference to characterize and quantify the inter-patient variations in tissue autofluorescence during autofluorescence bronchoscopy with Richard Wolf's diagnostic autofluorescence endoscopy (DAFE) system. The ...

Microcamera Embedded in a Wristwatch

Pierre-André Farine, Steve Tanner, Michael Ansorge, Patrick Stadelmann

The presentation reports upon the conception and realization of a miniature very low-power microcamera system that has been embedded in a wristwatch so as to enable the spontaneous capture of photographs in everyday life based on timekeeping devices the us ...

Apparatus for manipulating, modifying and characterizing particles in a micro channel

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre, Olof Pontus Linderholm, Urban Seger

Microfluidic system comprising a space (0207) for containing a liquid and at least one lateral chamber (0201) in communication with said space, said lateral chamber containing a metal electrode (0204). The lateral chamber and the space are designed to be f ...

Stereo Acoustic Echo Control Using A Simplified Echo Path Model

Christof Faller, Christophe Tournery

In handsfree tele- or video-communication, acoustic echoes arise due to the coupling between the loudspeakers and microphones. It is much more challenging to remove the undesired acoustic echoes for stereo or multi-channel tele-communication systems than f ...

Diffractive moire features for optically variable devices

Roger Hersch, Isaac Amidror, Sylvain Chosson

We present diffractive second-line security features based on the moire phenomenon, that are designed for use in Optically Variable Devices (OVDs). After a short introduction of our 2D and 1D moire methods, we first present the integration of line-based, 1 ...

Sensing and communication with and without bits

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The successful design of sensor network architectures depends crucially on the structure of the sampling, observation, and communication processes. One of the most fundamental ques- tions concerns the sufficiency of discrete approximations in time, space, ...

Design methodology based on the analog blocks retargeting from bulk to FD SOI using EKV model

Maher Kayal

This paper presents a methodology of a basic analog blocks retargeting from bulk to fully depleted (FD) SOI technology. The design methodology is generally not related to the model used for the circuit simulations. However, the proposed one is closely link ...

Diffractive elements designed to suppress unwanted zeroth order due to surface depth error

Hans Peter Herzig

We consider a design approach to reduce unwanted zero-order intensity due to profile depth error in diffractive elements. Our method is based on addition of local bias phase to a binary element phase, leading to the introduction of a third phase level. We ...
