  • Publication number: 20120143540
    Abstract: The power consumption detecting device is without external power supply. It installed on the electric equipment. This self-powered detecting device comprises at least one thermoelectric element, a processor and a wireless transmitter. As the electric equipment working, the temperature difference on the surface of the electric equipment drives the thermoelectric element to perform a voltage signal. Therefore, a self-powered thermoelectric detecting device will decrease standby power demand. The amplitude of voltage signal is proportion to the temperature difference. In the same time, the power generated by thermoelectric element may be another power source of the wireless transmitter and the chip or processor, so the supply of exterior power is no needed. The wireless transmitter transmits a signal, which is according to the power consumption of electric equipment or electric appliance, to the control center.

  • Publication number: 20120091246
    Abstract: A cord winder seat structure installed in a shutter rail for controlling opening/closing of the slats of the shutter. The cord winder seat structure includes a cord reel having a polygonal drum body. The polygonal drum body is composed of several plane sidewalls connected with each other. The polygonal drum body has several angles contained between the plane sidewalls. A pull cord is wound around the polygonal drum body for rotating the cord reel. The angles of the polygonal drum body serve as pull points for the pull cord. When a user pulls the pull cord to rotate the cord reel, the pull cord can apply a pull force to the angles to more precisely operate and locate the cord reel and save strength. An oblique slot is formed on a plane sidewall of the drum body on an inner side thereof to avoid tangling of the pull cord.
