A light and portable-type wireless physiological Concering the application of wireless transmissions in the signal retrieving system has always been a medical personnel's dream. To fulfill this dream, this paper investigates a feasible medical care, Pavlopoulos, et al. [1] installed GSM method to create a wireless-type physiological signal measuring communication systems inside ambulances to transmit vital system using a PDA and the bluetooth technology. The proposed physiological signals, such as electrocardiograms, heartbeats, system will reduce the service costs and raise the service efficiency blood pressures, and so on, to furnish prior preparations for for current medical care systems. The waveforms and data of hospitals. Yonghang Zang, et al. [2] developed a home-based physiological signals, such as electrocardiograms (ECGs), . . ' 1-4244-0726-5/06/$20.OO '2006 IEEE

For applications, having efficient modules with a large active area is paramount. In this work, two series of anthryl dyes were synthesized to study their fundamental properties and photovoltaic performance in dye-sensitized cells. After screening and optimization, a module sensitized with one of the dyes exhibits an overall efficiency of 13.48%, and it is capable of driving prototype application devices under indoor conditions. Chemical structures of the dyes are based on our previous champion anthryl dye (N,N-dioctyl-anilinyl-ethynyl-anthryl-ethynylbenzothiodiazoyl-benzoic acid or AN-11, 11.94%). The first series consists of AN-11 as a reference and two other dyes bearing either an isophthalic acid (AN-11D) or a hydroxamic acid (AN-11H). For the second series of the dyes, their chemical structures differ from the first series counterparts in an additional ethynyl bridge between the benzothiadiazole acceptor and the anchoring group. As expected, the second series of the dyes give rise to red-shifted UV−visible absorptions, fluorescence emissions, and positively shifted reduction potentials. Significantly, the AN-21 module outperforms others with an overall efficiency of 13.48% under 1000 lx of T5 fluorescent light. Appearance-wise, the color of the AN-21 module is darker than that of the already very dark AN-11 module, owing to its broader and more intense incident photon-to-current conversion efficiency (IPCE) spectrum. Finally, we prepared three prototype appliances to showcase the AN-21 module's ability of driving/powering real-life indoor applications.

Heari-sound stethoscoping is a vital referencefor regular physicians diagnosing a heartfunction. Many heart diseases are diagnosed via this tin^ stethoscope. We developed a wireless-trrmrmission heart sound diagnosis system that combines the bluetooth wireless function. The retrieval of heart sound signals is done through a selfmade heart sound sensor. Afer amplifiing mdfinering, the signals were transmitted in wireless mode by using the bluetooth module (CSR BCOZ). Another bluetooth modulein the other end was used to receive the heart sound signals. The signals were displayed and store in a personal digital assistant (PDA) as phonocardiography (PCG) ahta.
