In a method for calibrating a propagation-time-based localization system in a computer-assisted manner, the position of a mobile object in a predetermined environment can be determined by detecting propagation-time-based variables of multiple base stations, wherein the propagation-time-based variable of a base station represents the propagation time of a signal between an object radio unit and the base station. The object is moved and the variables of the base stations are detected in the process at multiple measuring times. The minimum value of the variables of a base station is associated with a predefined minimum distance between the object and base station and the maximum value with a predefined maximum distance. A predefined dependence of the distances between the object and base station is scaled to the association of the minimum and maximum value. The scaled dependence is then used when determining the position of the mobile object.

A safety system comprised of safety devices each worn by a caretaker and up to three people requiring minding, that alerts using color coded LED lights and audible tones when a monitored person is in danger. The device alerts if the person is beyond a preset distance, is close to or is in a body of water, or signals they are in trouble, using phased-array radar coupled with image processing. The phased-array radar allows the remote sensing of water in either daylight or night. The phased-array radar comprises multiple antenna elements including an independent antenna element phase shifter allowing beamsteering. The device scans an object using a preset beamsteering algorithm independent of movement. The multiple antenna elements and beamsteering improve image data accuracy which is then interpreted and correlated with a body of water characteristics.
