Abstract: A mechanically steered, horizontally polarized, directional antennae for aerial vehicles, such as UAVs. The antenna system can include a planar substrate with a horizontally polarized antenna embedded therein. A rotation member, on one end, can be attached to the planar substrate, and can extend from an external surface of the aerial vehicle. An actuator can be coupled to the rotation member to rotate the rotation member. A communication controller of the aerial vehicle can control the actuator to beam horizontally polarized radiofrequency (RF) waves to a target receiver or receive a wave front from a target transmitter.

Abstract: A detector device for detecting the presence of airborne particles such as smoke includes a light source, an optical bridge, a measurement path, a reference path, a measurement receiver and a reference receiver. The optical bridge, in addition to the light source and the measurement and reference receivers, are the only optical elements of the detector device. The optical bridge includes two circular apertures arranged downstream of the light source along the radiation path. The light source is arranged in a chamber having an air reservoir, whose surface area is substantially greater than that of the light source. A temperature drift curve is determined by heating the light source and storing the detector signal at different temperatures.
