Means to overlap at least a first projected image on at least one second real image

摘要

Means to overlap at least a first projected image on at least one second real image system to reduce the use of energy in a thermal control device comprises a transparency setting device (TAD) including a transparent physical element supplied with C Orrente AC to generate a set of states of transparency between opaque and totally transparent.The system also comprises a control device including a cavity closed by thermal walls and a thermometer adapted to control the temperature in the cavity. The TAD is incorporated in at least a part of one wall of the cavity. Tad reduces the energy consumption of the thermometer enabling the vision of the contents of the cavity without opening the cavity.
