Abstract: Disclosed embodiments provide systems and methods related to managing inventory by validating physical quantities of items in fulfillment centers for use with a user interface. A method for managing inventory comprises receiving, from a mobile device, a request for one or more validation locations, a zone for performing a validation, a validation type, and a round of validation, retrieving validation locations, each location associated with a status of not assigned, assigned, problem zone, or validated, and determining which of the retrieved validation locations needing assignment have a location in the received zone, a match in the validation type, and a match round of validation. Based on the determination, the method further comprises selecting one or more of the matching validation locations if a status of each determined validation locations is equal to not assigned and responding to the received request by transmitting one or more selected validation locations to the mobile device.

Abstract: The present disclosure provides systems and methods for stowing products, comprising a memory storing instructions and a processor configured to execute the instructions to receive a tote identifier associated with a tote containing at least one product for stowing, predict, based on the tote identifier, a location for stowing the product, and provide a location recommendation for stowing the product based on the predicted location. The processor is configured to receive a product identifier, a location identifier, and a quantity of the product to be stowed. The processor is configured to modify a database to assign the location identifier and the quantity to the product identifier, receive a notification of a stowing error associated with the tote identifier, modify the database to assign the stowing error to the tote identifier, and automatically report the stowing error.

Abstract: A REDOX flow battery or fuel battery includes a reactant storing and collecting unit for preventing leakage of a reactant. The battery includes two end plates and a stack that is disposed between the end plates and includes one or more unit cells. The reactant storing and collecting unit for preventing leakage of a reactant is disposed inside or outside the stack. According to the present invention, sealing reliability of the REDOX battery or fuel battery is dramatically improved. In addition, although a reactant or a product leaks from the stack, the reactant or the product may not leak to an outside of the battery but is collected before leaking to the outside. Therefore, the battery according to the present invention has an advantage of easy maintenance.

Abstract: A flexible display device is disclosed. The disclosed flexible display device includes a flexible substrate; a thin film transistor on the flexible substrate; and a light emitting diode or a liquid crystal capacitor connected to the thin film transistor. The flexible substrate includes: a first base layer; a second base layer on a first surface of the first base layer; and a third base layer on a second surface of the first base layer. A surface hardness of the second base layer is greater than a surface hardness of the third base layer, and an adhesion strength of the third base layer is greater than an adhesion strength of the second base layer.

Abstract: A flexible display device is disclosed. The disclosed flexible display device includes a display panel configured to display an image; and a back film under the display panel. The back film includes a plurality of depressed patterns at a surface adjacent to the display panel. The plurality of depressed patterns are spaced apart from each other and extend in a direction away from a center of the back film.

Abstract: A redox flow battery includes a flow path frame provided with a flow path conveying an electrolyte introduced into a fixing frame having a flow path for introducing and discharging an electrolyte supplied from outside. The flow path frame is provided with an inflow path connected to the flow path of the fixing frame and an outflow path discharging the electrolyte to an impregnation part conveying the electrolyte to a reaction surface of a membrane, thereby preventing leakage of the electrolyte that is caused by a difference between supply pressure and circulation pressure of the electrolyte.

Abstract: There are provided a cathode active material for a lithium secondary battery, a method of preparing the same, and a lithium secondary battery containing the same. The cathode active material for a lithium secondary battery includes: a compound reversibly intercalating and deintercalating lithium; and a coating layer positioned on at least a portion of a surface of the compound, wherein the coating layer is a composite coating layer containing Li3PO4 and LiF, and further containing a lithium metal compound, a metal oxide, a metal fluoride compound, and/or a combination thereof.

Abstract: Provided are a sulfonated poly(arylene ether) copolymer including a crosslinking structure and a polyelectrolyte membrane including the same. Particularly, a sulfonated poly(arylene ether) copolymer including a crosslinking structure in a polymer chain or at the terminal portion of the polymer chain, and a polyelectrolyte membrane including the same are provided. The polyelectrolyte membrane using the sulfonated poly(arylene ether) copolymer including the crosslinking structure, may have the same or better degree of a thermal stability, a mechanical stability, a chemical stability, a membrane forming capability, etc. than a commonly used polyelectrolyte membrane. In addition, the proton conductivity and the cell performance of the polyelectrolyte membrane may be remarkably improved than those of the commonly used polymer electrolyte. Further, the properties of the electrolyte membrane may be rarely changed, and a high measuring stability may be obtainable.

Abstract: A safety device for assuring safety of a user (a child) when he or she plays with the toy car and for preventing damage of an electric motor due to overload of the motor by automatically stopping the operation of the electric motor when the toy car runs into or when the toy car is under an idle conditions. The safety device includes an actuating switch adapted for maintaining or cutting-off the supply of the electric power to the electric motor and a micro switch having an actuating bar of which one end extends down to a frame of the toy car's body.
