Abstract: A robotic lawnmower (14) comprises a chassis (18), and an outer shell (20) defining an exterior face of the robotic lawnmower (14), the outer shell (20) comprising a skirt enclosing the chassis (18) at a distance therefrom. A sensor module (30; 34) comprises a chassis connection interface for mechanically connecting the sensor module (30; 34) to a module connection interface on the chassis (18). The sensor module (30; 34) holds the sensor outside a vertical projection of the chassis (18), between the chassis (18) and the skirt. The module connection interface is located on a top face of the chassis (18), and the sensor module housing extends downwards to a position vertically lower than the module connection interface. A cantilever member holds a main housing body of the sensor module (30; 34) with a horizontal gap between the main housing body and the chassis (18).

Abstract: An in vitro method for calculating a glomerular filtration rate of an individual or an indicator of a pathophysiologic factor of an impaired glomerular filtration rate is provided. The method may include the following steps: providing a blood sample from an individual; determining the concentration of at least three substances chosen from alanine, choline, creatine, creatinine, dimethyl sulfone, dimethylamine, glucose, glycerol, isoleucine, leucine, myo-inositol, N,N-dimethylglycine, and valine in the blood sample by analyzing the blood sample with a suited measuring technique; and calculating a predicted glomerular filtration rate or an indicator of a pathophysiologic factor of an impaired glomerular filtration rate from the determined concentrations of the substances.
