Abstract: A rain-resistant, drainless, heated air data probe assembly may comprise a probe having a central channel, one or more peripheral channels, and a heating element. In addition, inner surfaces of the channels may include hydrophilic surfaces, and the outer surface of the probe may include hydrophobic surfaces. The hydrophobic outer surface may reduce water ingress into the channels of the probe, and the hydrophilic inner surfaces may cause dispersion of water that has entered the channels. The heating element may further cause evaporation or running off of water on the outer surface, and may cause evaporation of dispersed water within the channels, which may further eliminate the need for a drain at a terminal end of the probe assembly.

Abstract: An average coefficient of static friction between skin and paper is determined based on pinch-strength measurements and a corresponding maximum weight of bucket and water before slippage occurs. With the coefficient of static friction determined, a pinch-strength threshold for impairment uniquely determines the threshold for a weight of a pinch test apparatus using one or more common or household material(s), such as bucket and water. A patient using such apparatus at home can therefore put sufficient water in the bucket to reach this weight and see if they can lift the bucket or not, thereby determining whether or not impairment exists.

Abstract: A method is provided for capturing a load spectrum of mechanical stresses which act on a machine element during an intended use. Mechanical stresses acting on the machine element are captured by a measuring apparatus of a load-spectrum-capturing device arranged on or in the machine element over a capturing period. Proceeding from the measured data acting on the machine element and captured by the measuring apparatus, a load spectrum depicting the mechanical stresses acting on the machine element is determined. In this method, partial load-spectrum data are calculated at time intervals by a load-spectrum-determining apparatus of the load-spectrum-capturing device proceeding from the captured measured data and the partial load-spectrum data are stored in a data-memory apparatus of the load-spectrum-capturing device. The partial load-spectrum data determined over the capturing period form a load-spectrum data set of a load spectrum.
