| 20120081775 | DISPLAY DEVICE - There is disclosed an electrochromic passive-matrix display, wherein each passively addressed pixel cell comprises an electrolyte ionically connecting an electrochromic and electrochemically active polymer and a layer of electrically conducting carbon. Thus, each pixel has a pronounced threshold voltage sufficient for reducing cross talk in an electrochromic display. | 04-05-2012 |
| 20110176143 | RESONATOR LENGTH MEASUREMENT - The invention provides a method and system for measuring the length of a reflective resonator, by analyzing an electromagnetic spectrum emitted therefrom. The emitted spectrum is used for estimating a first cavity length. This estimation is thereafter improved, by first computing at least one interference number for the spectrum, adjust this value to e.g. an integer or half-integer depending on the configuration of the resonator, and thereafter re-calculating the length of the resonator using the adjusted value of the interference number. The above is an efficient way of improving the accuracy in the determination of a physical property of a resonator. | 07-21-2011 |
| 20100081049 | Electrochemical Element - A battery having at least one positive and at least one negative electrode arranged alongside one another on a flat, electrically nonconductive substrate and connected to one another via an electrolyte which conducts ions. | 04-01-2010 |
| 20080223717 | Wettability Switch - The present invention relates to a wettability switch that comprises an electrochemically active element having a wetting surface with switchable wetting properties. The electrochemically active element comprises an electrochemically active polymer, and surface active molecules each having a lyophobic portion and a lyophilic portion. In the wettability switch, each of said surface active molecules exposes one of said lyophobic portion and said lyophilic portion towards said wetting surface, and the identity of said portion depends on an electrochemical state of said polymer. | 09-18-2008 |
