  • Preliminary Controlled Pre-Deformation Treatment for the Production of Mirrors
    Publication number: 20100246036
    Abstract: A method for the production of mirrors entails performing a preliminary controlled pre-deformation treatment of an optical system, consisting of the following phases: calculation of the deformation of the optical system due to a selected reflecting treatment; design of a deforming layer such as to produce on the optical system a deformation opposite to the one caused by the selected reflecting treatment; and deposition on the optical system of a deforming layer on which the selected reflecting treatment will subsequently be deposited.

  • Device for electrical and/or electronic telephone circuits, designed to limit the power dissipated within them
    Patent number: 5519775
    Abstract: A protection device, for a telephone (or other load) 27 in series with an external protection transistor 2, includes a sensor 6 for detecting common-mode current into the load. The output of the sensor 6 is connected to affect a current source/sink combination, and imbalance in this source/sink combination produces a voltage shift which is indirectly connected to control the protection transistor.
