This paper was inspired by an article entitled “An approach to model high-frequency distortion in negativefeedback amplifiers” by S. O. Cannizzaro, G. Palumbo, and S. Pennisi. The objective of this presentation is to point out that some results presented therein are not so novel as argued. First, we point out here that an idea of partition of a nonlinear circuit into interconnected smaller basic blocks,...
Over the last years, the use of multiple cameras is becoming more and more popular in today’s computer vision systems. Such approach is widely used in many applications, such as navigation of autonomous mobile robots, video surveillance, the movie industry, augmented reality or people tracking and identification systems. Surprisingly, little attention is paid in the literature to the practical calibration...
Meaningful progress in the fields of MEMS is associated with the continuous development of the micromachining technologies. One of the most promising devices in MEMS is thermal sensors. When the first microbolometer appeared on the market, a huge interest in thermal detectors was observed. This paper is a short overview study on microbolometer geometry, different solutions and possibilities to implement...
The paper presents the idea behind the implementation of a system designed to monitor biomedical parameters and the subject's behaviour on the basis of the architecture of measurement modules located on the body. The system was developed as a result of market launch of new generations of electronic devices combining high functionality, small size and low power consumption. The paper presents the elements...
The paper aims to present 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 arranged on the subject's body to a collective node (data integrator). At the same time, all the necessary properties are maintained, i.e. low power consumption of the modules, increased...
