This paper presents the fabrication of an integrated long-range thermal bimorph actuator that controls the z-position of an AFM cantilever in liquid. Multiplied in an array, such individually actuated probes can parallelize cell force spectroscopy measurements, thereby drastically reducing the time needed per measured cell. This particular approach implicates the need for devices with an individual...
We present a novel approach for hydrogen gas detection, based on palladium-coated micromechanical resonators. A sequence of thin film techniques allows the large-scale parallel fabrication of free-standing beams, from a counter-electrode by a mesoscopic air gap. The readout principle has been confirmed. The device manifests a resonance frequency drop from 6.5 to 3 MHz as it is exposed to 4 % of H2...
Pan-European project B21C (broadcasting for the 21st century) aims to develop technology for DVB-T2 (digital video broadcasting, terrestrial), which is a spectrum efficient broadcasting system for future. The evaluated technologies include MIMO, which has been widely studied in perspective of B3G (beyond 3rd generation) systems, but never for any UHF band systems. In addition, the latest decision...
This paper describes different techniques for mitigation of high power and long duration interference in terrestrial digital video broadcasting (DVB-T/H) systems. The interference is assumed to distort the DVB-T/H signal severely so that on average one fourth of the DVB-T/H symbol is lost. We investigate the use of long enough time interleaver in combination with simple soft bits scaling. Additional...
This paper provides results of the radio channel measurements performed in DVB-H network during autumn 2006. The purpose of these measurements was to acquire additional channel information in order to validate the channel models constructed from the earlier measurements [1], [2]. This paper presents the most relevant results of the measurements including Ricean K-factors, RMS delay spreads, total...
