Research and development in life sciences domain brings every day many innovations. Some of them have been enabled (or improved) by the micro-electronics. Several examples are described in this paper. A big challenge in the design of such systems is that the biological part cannot be uncoupled from the rest of the system during the design process. The integration of biological parts in system's design...
The goal of this research work is to explore technology and memory architectures to reduce power consumption with low area and high speed of operation. We proposed two different architectures of SRAM memory. First is focused on reducing dynamic power consumption and area, with high speed of operation. Second architecture is focused on reducing leakage power with good speed and optimized area.
The applicability of formal methods to support for software development is discussed in the paper. Software for realtime systems (esp. Safety Critical Systems) is of special interest. Petri nets, Alvis language and temporal logic are examined in which way they may support the development process. Selected approaches for using methods and related examples are discussed to answer the question stated...
Low light detection, down to the single photon, has been possible so far relying on photo-multiplier tubes (PMT). PMT are certainly a reliable, solid rock technology with decades of improvements and refinements. Their architecture is certainly beautiful but irreducibly complex. Biasing electronics can be sophisticated but the operational voltage necessarily exceeds 1000 V. Operation in magnetic fields...
New generations of electronic devices have become more sensitive to the effects of the natural radiation coming from the surrounding environment. These radiation sources are cosmic rays and radioactive impurities, able to corrupt the content of memory cells or to induce transient pulses in combinational logic. The growing sensitivity is due to the lower charge needed to define the logic levels in...
A system-on-chip allowing dynamic measurement and processing of the most important human physiological parameters has been presented. The BioChip consists of analog front-ends, analog to digital converters and a two core 32-bit microcontroller Azurite. The two core architecture allows to control the signals' acquisition, data processing and communication with the peripherals simultaneously. The microcontroller...
The paper presents the idea behind the implementation of the BioSiP system designed for monitoring biomedical parameters and the patient's behaviour, based on the architecture of a measurement module system located on the subject's body. The system could be developed owing to the market launch of new generations of electronic devices combining high functionality, small size and low power consumption...
This paper presents the study on the automatic computer-aided balance assessment system. The approach employs ambient assisted living architecture based on inertial sensors. The assessment relies on selected activities from the Berg Balance Scale test by means of the system supplied by a set of features extracted from the accelerometric signals. The feature space dimensionality reduction stage selects...
The article presents the first attempt for design of an autonomous measurement system to aid assessment and to determine the psychological profile of soldiers. A method for ascertaining the psychological profile is presented including the physiological signals being generated by the monitored subject as an important element thereof. The measurement system used in the preliminary experiments and the...
The article is aimed at presenting the organizational concept of the wireless personal area network (WPAN network) transmitting biomedical data, used in the BioSip system. The network transmits data from recording modules attached to various locations on the subject's body to a collective node (data integrator) while maintaining all the necessary properties, such as low power consumption of the modules,...
This paper presents a study aimed to assess applicability of artificial neural networks (ANNs) in human activity recognition from simple features derived from accelerometric signals. Secondary goal was to select the most descriptive signal features and sensor locations to be used as inputs to ANNs. Five triaxial accelerometers were attached to human body in the following places: one at back, two at...
Nowadays, in the age of technological development in various areas of life there is a growing interest in non-invasive techniques useful in medical examination. Angiology also called vascular medicine is a medical specialty with interest of diseases and disabilities of the human circulatory system. This domain uses different types of imaging. The acquired images are used for research, diagnostic,...
