Abstract: The present invention describes an autonomous building system capable of operating based on processing and analysis of collected data by means of Artificial Intelligence algorithms. The data can be gathered from within the system and/or from external networks. The autonomous building system will assist its users in every tasks from enhanced security to energy savings, from health monitoring and data collection to education, from financial assistance to social activities. In particular the described autonomous building is capable of making autonomous decisions and online purchases getting funds out of a dedicated financial account. The autonomous building may become the target of contextual advertising to promote products and/or services.

Abstract: The present invention describes a semiconductor interferometric reflecting device capable of modulating the reflected light by modulating the carrier concentration inside a semiconductor device. The variation of the carrier concentration within the device causes the variation of the physical optical properties inside the semiconductor material leading to a shift of the reflected and absorbed light spectrums. The modulating layer is fabricated on an optically smooth substrate, i.e., sufficiently smooth to allow for the occurrence of interference effects. Furthermore, if desired, the same device can be designed to emit or reflect the desired light. The present invention may be utilized for a reflective flat panel display comprising an array of semiconductor interferometric reflecting devices.
