Abstract: The present invention presents a movable sky light assembly used on a opening of a roof comprising a fixed frame, a wing frame with a lighting member supported on the fixed frame, said fixed frame being equipped with a driving device to operate said wing frame capable of opening and closing by connecting members for the frames. The fixed frame is provided with a detecting device for rainfall and the detecting device comprises a detecting sensor and its protecting means, and the sky light is constructed so as, when the wing frame is open, the detecting sensor of the detecting device is in the working posture and, when the wing frame is closed, the detecting sensor is protected by the protecting means. As the sky light is used also for ventilation, the connecting members of the frames are formed as a operating member of the wing frame and various aspects of the rain detecting device to close the wing frame in the rain is disclosed in relation to the operating member.

Abstract: A signal conditioner for converting non-standardized analog signals from a variety of sensors of temperature, pressure, and flow rate, into standardized signals which are accurately readable by a computer; wherein an analog to digital converter converts the non-standardized analog signal into a digital signal, arithmetic circuit effects a predetermined arithmetic operation on the digital signal, pulse outputting circuit takes the arithmetic results and generates a pulse signal having duty ratio corresponding thereto, and filter circuit smooths the pulse signal and generates the standardized signal which represents the non-standardized analog signal from the different sensors.
