Patients with arrhythmias would greatly benefit from daily ECG monitoring, both for diagnosis and therapy optimization. The aim of this study was to simulate several ECG monitoring strategies which could help in optimizing a home monitoring device. Simulations were performed using data from patients implanted with DDD-CLS pacemaker for Brady-Tachy Syndrome (Burden II Study). The data analysis was...
To detect and measure all the positions and movements of human hands, a data glove with bend sensors presents relevant advantages with respect to other solutions based on video-cameras. However, most of these advantages would be lost if wired connectivity is utilized. This paper presents the implementation of a wireless connection based on ZigBee protocol specifications to transmit the acquired data...
Synthetic biology is a science resulting from the connection between biotechnology and engineering sciences. It aims to design and build new biological systems and functions. The ability to design a new biological function according to given specifications includes many steps. One of the big issues is to formalize a design methodology and to develop adapted tools. One way to explore is to adapt the...
The Artificial Accommodation System is an autonomous mechatronic implant aiming at restoring accommodation after cataract treatment or in the case of presbyopia. The employed sensor concept requires a continuous wireless data exchange between the two systems implanted in the left and in the right eye, respectively. In this paper, we present three strategies for establishing this inter-implant communication...
A theoretical investigation of the travelling-wave approach for high field magnetic resonance imaging (MRI) is presented. The travelling wave probes excite the fields in the longitudinal direction of the bore, so that the effects of the attenuation constant due to high permittivity and lossy tissue need to be calculated. In addition, the travelling wave modes should affect the B1+ field homogeneity...
Presbyopia and cataract are increasing concerns in the aging society. Both age-related ailments go along with a loss of ability to accommodate. A new approach to restoring the patients' ability to accommodate is the Artificial Accommodation System which will be implanted into the capsular bag to replace the human crystalline lens. Depending on the actual need for accommodation, the Artificial Accommodation...
Holter recording of electrocardiographic signal (ECG) is usually disturbed by noise added to measured useful signal due to e. g. worse contact skin-electrode, body movements, etc. Our general goal is to find at least some piece of information from ECG (in our case - positions of QRS complexes) in corrupted signal, on which common preprocessing methods fail. The main purpose of the article is description...
A lot of research in the radio domain has focussed on integrating autonomy and smartness capabilities inside future radio equipments like mobile phones. Such a smart radio is called a cognitive radio. This requires complementary management facilities to be added to the radio signal processing facilities present in traditional radios. Hierarchical and Distributed Cognitive Radio Architecture Management...
This contribution presents a system designed to monitor the fracture healing progress after osteosynthesis of the femoral bone, using an intramedullary nail. The instrumented nail enables the surgeon to perform stiffness measurements of the bone/implant system in vivo. Various techniques have been developed in the past to measure the stiffness of the callus, but little research has been done on fractures...
Wireless Body Area Networks (WBAN) has emerged as a key technology to provide real-time health monitoring of a patient and to diagnose and treat many life threatening diseases. WBAN operates in close vicinity to, on, or inside a human body and supports a variety of medical and non-medical applications. IEEE 802 has established a Task Group called IEEE 802.15.6 for the standardization of WBAN. The...
In this paper, we propose a computationally efficient fall detection algorithm which exploits visual observations. The proposed architecture is designed to be suitable for devices of low processing capabilities allowing a large scale implementation of the proposed IT technology in the area of aiding elderly or persons' with dementia. In contrast to other approaches, visual surveillance is more natural...
We are interested to study the dynamics of state change or the complexity of state for several systems. Information dynamics (ID) is a new concept introduced by Ohya to construct a theory under the ID's framework by synthesizing these investigating schemes. In ID, a complexity of state describing system itself and a transmitted complexity between two systems are used. One of the example of these complexities...
The change in age-structure of a society, leaves many countries facing a problem. The rapid rising numbers of senior citizen and care-taking personnel numbers can't match the problems and needs of these citizens. Use of smart, ubiquitous technologies can offer ways in coping with the need of more nursing staff and the rising costs of taking care of senior citizens for the society. Helping senior citizens...
We have previously described a feedback loop that combines an auditory processor with a low-power analog integrated-circuit vocal tract to create a speech-locked-loop. Here, we describe how the speech-locked loop can help improve speech recognition in noise by re-synthesizing clean speech from noisy speech. Therefore, it is potentially useful for improving speech recognition in noise, important in...
This paper describes the road of RIWCoS architecture for reconfigurable interoperability and service continuity in wireless hybrid communications: from the IEEE 802.21 MIH standard, through generic modules design and specification, toward implementation and integration. Given the results obtained during the development of the prototype demonstrating a vertical handover, we can affirm that there is...
The world is experiencing an increase in both natural and man-made disasters. Different parts of the world experience varied and varying effects of the disasters depending on their physical, social, political and economic environment. These disasters have negative effects which include: loss of human and animal life; loss of property; and destruction of the livelihood systems. Given this scenario...
With the emergence of visual sensor networks (VSN), low power wavelet-based coder (WBC) is becoming increasingly mandatory. This makes the selection of the appropriate wavelet, among many competitors, not an easy task. In our context, the appropriate wavelet is that one which dissipates low energy during image decomposition, while having an adequate quality of the reconstructed image at the reception...
Recently, there has been an increasing interest in applying wireless sensor networks for health status monitoring both on and within the human body. Low power consumption is crucial in such applications, especially for implanted devices. UWB transmission is one way of making low power transmission possible. A further reduction in power consumption can be achieved through efficient signal compression...
Advancements pursued in the last tenths of years in technology have been applied to medicine encouraging therapy and diagnostic procedures more and more sophisticated. The development of new biocompatible materials able to be integrated in human body needed to cure tissues and organs damaged is a very promising area of application to be investigated. However, information about biocompatible materials...
Increasing the efficiency of mobile communication networks while keeping operational and maintenance cost at reasonable level is a major task for operators. Multimode radios capable of operating according to various mobile broadband standards, such as WCDMA, WiMAX and LTE, represent the new trend for resolving these challenges. A transparent radio solution, agnostic to wireless standards, with high...
