20100259810 | ELECTROCHROME ELEMENT DRIVER - An electrochrome element driver supplies electrical power to an electrochrome element and includes an amplifying circuit, a variable resistor element, and a capacitor. The amplifying circuit has a control input for controlling a supply current flow to the electrochrome element, a feedback input, and an output. The variable resistor element has a first resistor terminal, a second resistor terminal coupled to the feedback input and a resistor control terminal for controlling a resistance of the variable resistor element. The resistor control terminal is coupled to the amplifying circuit output, the first resistor terminal is coupleable to a power source, and the second resistor terminal is coupleable to the electrochrome element such that a supply current path to the electrochrome element through the variable resistor element is formed. The capacitor is coupled to the resistor control terminal for effecting a stable behavior of the supply current flow to the electrochrome element. | 10-14-2010 |
