Abstract: An embodiment structural battery for an electric vehicle includes an upper rail and a lower rail coupled with the upper rail, wherein the upper rail and the lower rail are electrically connected with each other by a terminal and a wiring, so that the upper rail and the lower rail electrically connected with each other serve as both the structural battery and a roof rail of a vehicle body.

Abstract: An embodiment structural battery for an electric vehicle includes a plurality of cells stacked on each other, each of the plurality of cells including a positive electrode layer, an electrolyte layer, and a negative electrode layer stacked with the electrolyte layer between the positive and negative electrodes, wherein the plurality of cells define a battery by electrical connection of a positive electrode terminal and a negative electrode terminal respectively provided in the plurality of cells, structure reinforcement layers stacked on each of an outermost upper layer and an outermost lower layer of the plurality of cells, and carbon fiber current collecting layers stacked between each of the structure reinforcement layers and the plurality of cells.

Abstract: The present invention relates to a method for preparing an alkali metal ion conductive chalcogenide-based solid electrolyte, a solid electrolyte prepared thereby, and an all-solid-state battery comprising the same.

Abstract: A dental impression kit and method is provided. The kit includes a single-use container filled with a polyvinyl siloxane (PVS) base, a single-use container filled with a PVS catalyst, a dispenser filled with a light body PVS, an impression tray having a curved channel sized and shaped to surround one of an upper or lower dental arch and an instruction packet. The method includes opening the single-use containers, and mixing the PVS base and PVS catalyst to form a PVS mixture. The method includes pressing the PVS mixture into the impression tray, pressing the impression tray onto one of an upper or lower dental arch to form a first dental impression. The method includes opening the single use dispenser, ejecting the light body PVS over the first dental impression, and reseating the impression tray to form a second dental impression.

Abstract: An electronic device and a bias control method thereof are provided. The electronic device includes a channel quality measuring module configured to measure a channel quality of a received signal, a bias offset determining module configured to determine a bias offset based on the measured channel quality, a bias offset applying module configured to modify a bias by applying the determined bias offset to a specified bias value, and a power amplifier configured to amplify transmission power according to the modified bias.
