    Abstract: An electro-optic element having enhanced durability by the addition of an additive. The additive may enhance the durability of the electro-optic element by reducing or eliminating the effects of water on species with the electro-optic element, such as the electrolyte. Specifically, the additive may operate to reduce or eliminate the formation and/or accumulation of hydrogen fluoride within the electro-optic element by interaction of the electrolyte with water or alcohol molecules. In some embodiments, the additive may be an organosilicon species, such as (3-cyanopropyl) dimethylfluorosilane.

    Abstract: A window assembly includes an electro-optic element which has a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity. The electro-optic medium is switchable such that the electro-optic element is operable between substantially clear and darkened states. An absorptive layer is positioned on the fourth surface of the electro-optic element and a reflective layer is positioned on the absorptive layer.

    IPC: G01M3/24

    Abstract: A plumbing detection system includes a detector configured to be coupled to a fluid system which includes a pulse generator configured to emit a pulse into a fluid within the fluid system. A pulse receiver is configured to detect a reflected pulse. A transmitter and a base station is configured to be coupled to the fluid system. The base station includes a receiver in communication with the transmitter and is configured to cause a reduction of a flow of the fluid within the fluid system in response to the receiver receiving a signal from the transmitter of the detector.
