In this paper an ultra-wideband 80 GHz FMCW-radar system for contactless monitoring of respiration and heart rate is investigated and compared to a standard monitoring system with ECG and CO<sup>2</sup> measurements as reference. The novel FMCW-radar enables the detection of the physiological displacement of the skin surface with submillimeter accuracy.(More)
This paper presents a newly developed Transcutaneous Energy Transfer (TET) System to supply an electromechanical implant with energy. The system is capable of delivering a power of 1-5 W to the implant over a distance of up to 5 cm via an inductive link with a frequency of 100 kHz. Additionally, the inductive link incorporates a data link which allows(More)
Because of their obvious advantages, active and passive optoelectronic sensor concepts are being investigated by biomedical research groups worldwide, particularly their camera-based variants. Such methods work noninvasively and contactless, and they provide spatially resolved parameter detection. We present 2 techniques: the active photoplethysmography(More)
Purpose – The purpose of this paper is to develop an automatic control system for mechanical ventilation therapy based on the open lung concept (OLC) using artificial intelligence. In addition, mean arterial blood pressure (MAP) is stabilized by means of a decoupling controller with automated noradrenaline (NA) dosage to ensure adequate systemic perfusion(More)
In this work new algorithms are presented and discussed which extend the conventional minimum / maximum alarms in patient monitors. Two of the most important parameters indicating the patient's condition during a surgical intervention are blood pressure and heart rate. Hence, these parameters are engaged in the assessment of anesthesia control. The computed(More)
During the last years the significance of RFID systems has increased rapidly. In fact, its use is expected to increase by a factor of twenty until 2016. Medical applications are expected to be a main cause of this development. Currently, RFID systems are primary identification systems, based on the transmission of a key number or little further information.(More)
Early detection of lung edema for patients suffering from chronic heart disease improves the medical treatment and can avoid committal of the patient to an intensive care unit. Therefore, an early warning system monitoring the amount of fluid in the lungs by measuring trans-thoracic bioimpedance outside the body has been developed. The proposed(More)
