Space-saving broadband antenna with corresponding transceiver

Abstract: The invention relates to a space-saving broadband antenna, especially for independent portable stations used in networks for radio communication with land-based mobiles, comprising a substantially flat element (33), called horizontal element, and a short-circuit element (35) substantially perpendicular to the said horizontal element (33), called vertical element (35), the said vertical element connecting a first extremity (34) of the said horizontal element (33) to the electrical earth of a processing unit, and the said UHF signals being transported between the said processing unit and the said horizontal element (33) by a coaxial cable (311) connected to the said horizontal element (33), the said horizontal element (33) comprising: - a substantially rectangular intermediate surface (36), a first extremity of which corresponds to the said first extremity (34) of the said horizontal element (33); and - at least two strands (37, 38), substantially parallel to each other and substantially perpendicular to the said vertical element, the second extremity of the said intermediate surface (36) corresponding to a first extremity (313, 314) of each of the said strands (37, 38).

The ARESA Project: Facilitating Research, Development and Commercialization of WSNs

Abstract: Within academia, wireless sensor networks have witnessed a tremendous upsurge in the last decade, which is mainly attributed to their unprecedented operating conditions and hence unlimited research challenges. Within industry, the projected business opportunities are huge with, e.g. according to Frost & Sullivan, an expected market size of approximately $2b by 2012 at a compound annual growth rate of 41.9%, therefore causing the interest in this technology to augment dramatically. The aim of the ARESA project is to capitalize on this academic and industrial momentum and provide clear and knowledgeable guidelines and solutions related to the research, development and commercialization of this emerging technology. The diverse background of the involved partners facilitates unprecedented insights into the design process from conception to revenue makings. This paper aims at summarizing some key issues one encounters when researching medium access control and routing protocols, formally verifying their proper functioning, developing low-power hardware, and finally commercializing wireless sensor networks.

Improving Intra mode coding in H.264/AVC through block oriented transforms

Abstract: In an H.264 video encoder, the important task of intra coding is performed in the residual domain after a spatial transform has been applied to the block data. Although the intra prediction is very efficient and shows the ability to capture some orientations of the image, after this spatial prediction the intra residual may still show regular structures. To take this possible regularity into account, especially orientation, we propose a pre-processing stage that selects the best rotation to be applied to the block among a set of predefined rotations. To this end, we utilize a rate-distortion algorithm. We further propose to calculate the real orientation of the block to decrease the amount of computation. Experimental results show that compared to the standard intraprediction mode of H.264, the proposed method can gain up to 1 dBs.
