Continuous Non-Invasive Blood Pressure Measurement Using 60 GHz-Radar-A Feasibility Study.

Blood pressure monitoring is of paramount importance in the assessment of a human's cardiovascular health. The state-of-the-art method remains the usage of an upper-arm cuff sphygmomanometer. However, this device suffers from severe limitations-it only provides a static blood pressure value pair, is incapable of capturing blood pressure variations over time, is inaccurate, and causes discomfort upon use.

A dataset of radar-recorded heart sounds and vital signs including synchronised reference sensor signals.

Radar systems allow for contactless measurements of vital signs such as heart sounds, the pulse signal, and respiration. This approach is able to tackle crucial disadvantages of state-of-the-art monitoring devices such as the need for permanent wiring and skin contact. Potential applications include the employment in a hospital environment but also in home care or passenger vehicles.

Radar-Based Heart Sound Detection.

This paper introduces heart sound detection by radar systems, which enables touch-free and continuous monitoring of heart sounds. The proposed measurement principle entails two enhancements in modern vital sign monitoring. First, common touch-based auscultation with a phonocardiograph can be simplified by using biomedical radar systems.

Six-Port Based Interferometry for Precise Radar and Sensing Applications.

Microwave technology plays a more important role in modern industrial sensing applications. Pushed by the significant progress in monolithic microwave integrated circuit technology over the past decades, complex sensing systems operating in the microwave and even millimeter-wave range are available for reasonable costs combined with exquisite performance. In the context of industrial sensing, this stimulates new approaches for metrology based on microwave technology.

A prospective noninterventional study to document implant success and survival of the Straumann Bone Level SLActive dental implant in daily dental practice.

Objectives: Clinical studies to assess dental implants are common in implantology, but such studies are usually performed for specific indications and following a specific protocol with strict inclusion and exclusion criteria. The aim of the current study was to evaluate the Straumann Bone Level SLActive dental implant in a prospective, multicenter, noninterventional trial.

Method And Materials: The implant could be used in whatever manner was deemed suitable by the clinician, within approved indications.
