Received Aug 2, 2017 Revised Nov 24, 2017 Accepted Dec 18, 2017 ZigBee is an IEEE 802.15.4 standard for information interchanges with business and purchaser gadgets. It is composed around low-control utilization permitting batteries to keep going forever. The ZigBee standard gives system, security, and application bolster administrations working on top of the IEEE 802.15.4 Medium Access Control...

This paper presents the data capture methodology and design of a home care system for medical-based surveillance and man-machine communication. The proposed system consists of the video-based subject positioning, monitoring of the heart and brain electrical activity and eye tracking. The multimodal data are automatically interpreted and translated to tokens representing subject’s status or comm...

The requirements for the analogue front-end for an ADSL modem are discussed, based upon the modem performance and the signal, noise and distortion-signal flows in the system. The relation between the various blocks and the asymmetric nature of the transmission are highlighted and their impact on the different blocks of the analog front end is indicated. The SNR specification of the A/D converte...

Modern reconfigurable systems contain 100,000+ programmable logic elements. In order to program these devices, we must rely on system level design techniques to manage the complexity and increase the efficiency of the designer. In this paper, we present a physically aware system level design flow for mapping high level application specifications to programmable logic. In particular, we study th...

Computer systems, often called hospital information systems (HIS), have been installed in most large Japanese hospitals for administration of the basic medical information of patients, for making entries on medical charts, and for prescribing medication. In almost all cases, HIS have a server/client type structure, with the servers and client terminals connected with a LAN. For voice communicat...
