Abstract: Disclosed is a power storage device and method for discharging the same, which configures the power storage device to perform an electric power output under a discharging limit upon coupling with a load device and before any authentication is conducted. The discharging limit for the electric power output will be lifted only when an authentication result between the power storage device and the load device indicates a successful authentication.

Abstract: A semiconductor structure includes a first metal-dielectric-metal layer, a first dielectric layer, a first conductive layer, a second conductive layer, and a second dielectric layer. The first metal-dielectric-metal layer includes a plurality of first fingers, a plurality of second fingers, and a first dielectric material. The first fingers are electrically connected to a first voltage. The second fingers are electrically connected to a second voltage different from the first voltage, and the first fingers and the second fingers are arranged in parallel and staggeredly. The first dielectric material is between the first fingers and the second fingers. The first dielectric layer is over the first metal-dielectric-metal layer. The first conductive layer is over the first dielectric layer. The second conductive layer is over the first conductive layer. The second dielectric layer is between the first conductive layer and the second conductive layer.

Abstract: The present invention relates to a tension control device of a twist pay-off system, especially a triple twist system, which uses mechanical control devices to keep the wires and strands in constant tension to produce qualified cables. The twist pay-off system mainly includes a constant control device and a tension reducer device, both of which have an active arm, a weight and several wheels for guiding the wires and the cables. By use of the weight under attraction of gravity, the devices can control the transport speed and keep them in a related constant tension all the time.
