摘要:
A system and method of appropriate services detection for a smart building are disclosed in the present invention. The invention may select appropriate services for a house or a building. After a user lives in a smart building with the system of the present invention for a period of time, the system uses the service gateway to collect and analyze environment information and appliance information so as to find relationship within appliances, sensors and actuators. Thus the cloud service platform selects appropriate services for the building to avoid downloading or installing an inappropriate service by a user. Further the cloud service platform may suggest a user buying additional equipment for matching the requirement of a service. The system of the present invention may learn a relationship of devices; locate positions of devices; and automatically collect state data of appliances to identify the appliances.

A power monitoring device for identifying the state of an electric appliance based on user feedbacks and a power monitoring method thereof are provided. The power monitoring device includes a measurement module, a variation detection and search module, and an electric appliance signature database established based on user feedbacks. When the measurement module detects a variation of a power consumption feature, the variation detection and search module searches the electric appliance signature database according to the variation to obtain electric appliances similar to the variation and the states thereof. A user contributes data to the electric appliance signature database by confirming the search result, or selecting the correct electric appliance and the state thereof. When the user confirms the search result, the power monitoring device establishes an association between the electric appliance and its electric appliance signatures and updates the electric appliance signature database.

An inner scattering billboard includes a light directing body, an advertising membrane and a light source. The light directing body contains a plurality of light directing particles inside to diffuse and direct light. Thus light rays emitted from the light source into the light directing body are scattered to allow the light directing body to become a planar light source of even luminosity. The advertising membrane has an advertising symbol located on the surface to be evenly illuminated. The billboard can be made thinner. An LED may be adopted as the light source to save electric power and reduce user's operation cost.

A high efficiency colored solar cell is described. The high efficiency colored solar cell includes a substrate, a first antireflection layer formed on the substrate, a second antireflection layer formed on the first antireflection layer. A color of a reflecting light of the high efficiency colored solar cell can be controlled according to the combination of the first antireflection layer and the second antireflection layer.
