The Inverted Pendulum model is one of favorite algorithm used to calculate the length of gait. The human locomotion is approximated by simple pendulum, the influence of knee and ankle movements are not considered. The gait length is calculated from the extremes of vertical position of human Center of Mass (CoM) during gait. This approach is usually used in measurements which uses inertial sensors...
This paper presents an algorithm for the objective assessment of the motion of a body during health-evaluation physical tests using our inertial sensor, namely the ActimedARM. With the orientation quaternions provided by the sensor and integrating twice the calibrated acceleration measurements, we are able to compute the displacement of the sensor worn by a patient. To validate our data we have made...
This paper describes design and testing of bioelectrical measurement by capacity electrodes. The advantage of this measurement type lies in an indirect-contact between the electrode surface and skin and movement artifact protection. The measurement is easier and more comfortable since capacitively coupled electrodes eliminate the need for conductive gel and direct skin contact with the electrodes...
Remote home care systems, which takes care about elderly people are going to be very necessary and useful in a few years. The population gets older and we need to solve problem how to take care about our related elderly. This article is mainly focused on movement activity monitoring of elderly people in their flats, which are equipped by our Homecare System. This system consists of PIR sensors, TILocation...
The need of continuous blood pressure measurement is usable in wide spectrum of applications from physicians practice to home care applications. Many types of blood pressure measurement devices can be bought in electronics shops. All such devices are contact measurement devices which need to be in contact of human body (hand or foot mainly). Secondary they allow only one measurement per several minutes...
