  • Patent number: 7652812
    Abstract: A method of supplying an electrically controllable system having variable optical/energy properties in transmission or in reflection, including at least one carrier substrate with a multilayer that allows migration of active species, including at least two active layers separated by an electrolyte, the multilayer being placed between two electrodes connected respectively to upper and lower current leads respectively. In addition to a constant first energy potential, a time-varying second energy potential is applied between the current leads, the first and second energy potentials being designed to ensure switching between two states having different optical/energy properties in transmission or reflection.

  • Publication number: 20090323157
    Abstract: An electrically controllable/electrochemical device, having variable optical and/or energy properties, including at least one carrier substrate including a first electronically conductive layer, a first electrochemically active layer capable of reversibly inserting ions such as cations, H+, or Li+, or anions, OH?, or anions made of an anodic (or respectively cathodic) electrochromic material, an electrolyte layer, a second electrochemically active layer capable of reversibly inserting the ions, or made of a cathodic (or respectively anodic) electrochromic material, and a second electronically conductive layer. At least one of the electrochemically active layers capable of reversibly inserting the ions, or made of an anodic or cathodic electrochromic material, has a sufficient thickness to allow all the ions to be inserted without electrochemically disfunctioning the active layers.

  • Patent number: 5016709
    Abstract: A process for the assisted recovery of heavy hydrocarbons from an underground formation having a plurality of superimposed reservoirs for the hydrocarbons involves arranging horizontal sections of a plurality of wells so that a first well of a first series of wells extend into a reservoir and is located essentially vertically below a horizontal section of a second well located in an immediately adjacent reservoir, with the first well being used as a steam injection well and the second well being used as a hydrocarbon-producing well.
