  • Publication number: 20180088431
    Abstract: An electrochromic (EC) privacy window includes an EC pane unit including a first EC device having a bright state and a dark state, and a privacy device facing the EC pane unit and having a bright state and a privacy state configured to attenuate visible radiation transmitted through the window. In some embodiments, when the privacy device is in the privacy state, the window has transmitted haze of greater that 80%. In other embodiments, when the privacy device is in the privacy state and the first EC device is in the dark state, the window has a visible transmittance of about 0.1% or less.

  • Publication number: 20160051600
    Abstract: The invention relates to the fields of application of health, biotechnology and nutrition, the aim of the invention being to provide a gelatinous mixture of probiotics and prebiotics with synergic symbiotic action for the treatment of chronic renal disease, the characteristics and components thereof reducing the concentration of uremic toxins, improving the renal function of the patient with an increase in urea, creatinine, uric acid, p-cresols or indoles in the blood. The gelatinous mixture of probiotics and prebiotics with synergic symbiotic action for the treatment of chronic renal disease is easier to administrate orally as it does not require the consumption of liquids for the administration thereof, reducing liquid retention. Another advantage of the present invention is the fact that it refers to live and active bacteria. The present invention is also used a primary source of food with known prebiotic effects, an element which is not considered in other inventions; it is not in a pharmaceutical form.
