Abstract:
A multisensor employs an optical system that is modified by the index of refraction of fluid passing between a light emitter and light detector to successfully distinguish between air and water (of any turbidity) and between water of different turbidity values. The optical system may employ lenses contacting the fluid to change their focal length and thus to focus and defocus light on the light detector depending on an index of refraction of the fluid.
Abstract:
A capacitive sensor assembly for detecting a fluid level within a removable tank of a domestic appliance along an axis, mountable within the domestic appliance, including at least one fluid level electrode including a resiliently deformable contact member adapted to contactingly engage with the removable tank received in the domestic appliance and convey at least one electrical field generated by the capacitive sensor into the removable tank.
