Abstract: The Mini 3D orientation sensor device has convex spherical body structure in a mechanical sensor coupled to logic to manage the reverse touchscreen component, alarm and other functions for the sensor. The spherical housing sensor is comprises a plurality of layers analogous to a touchscreen complete with conducting probes, an unconstrained surface compressing ball dynamic inside the spherical grid position structure that closes a electric circuit upon depressing the inside surface of the sphere housing. The sphere depressed coordinates are mapped to its 3D orientation upon output.

Abstract: The exposure of an aircraft component to an oxidation catalyst, such as a deicing solution, may be detected with the aid of an electrical conductivity sensor. In some examples, a system includes an aircraft component, an electrical conductivity sensor mechanically connected to the aircraft component and configured to generate an output, and a processor configured to detect an oxidation catalyst exposure event based on the output generated by the electrical conductivity sensor. The electrical conductivity sensor may be configured and positioned to generate a signal indicative of electrical conductivity of a substance to which the aircraft component is exposed. The processor may be configured to detect an oxidation catalyst exposure event by at least determining whether the electrical conductivity indicated by the signal is greater than or equal to a predetermined conductivity threshold value.
