Provided is a lithium secondary battery including a discharge unit capable of delaying or preventing a battery explosion. The lithium secondary battery includes a discharge unit disposed parallel to a battery body. The discharge unit includes a first electrode connected to a positive electrode of the battery body, a second electrode connected to a negative electrode of the battery body, and a discharge material film, disposed between the first electrode and the second electrode, inducing a abrupt discharge above a predetermined temperature. The discharge material film, e.g., a abrupt metal-insulator transition (MIT) material film can induce a abrupt discharge, thereby preventing or delaying a battery explosion.

Provided are a system and method for enforcing a radio frequency identification (RFID) event management policy. The system includes a policy definer for defining an RFID event management policy to be used by a client to manage an apparatus on the basis of an RFID event, a policy storage for storing the RFID event management policy, a policy determiner for selecting the RFID event management policy stored in the policy storage using a profile of the client included in an RFID event management policy request when the RFID event management policy request is received from the client, and a policy enforcer converting the selected RFID event management policy according to a standard executable by the client.
摘要:
A method and system of preventing a loss/theft of a surveillance target including a mobile device using a wireless personal area network (PAN) or a wireless local area network (LAN) which can receive, from the mobile device included in the surveillance target via a gateway, location information of the surveillance target generated by using mobile device information for the surveillance target, the mobile device information being collected by a sensor of the mobile device, and signal information communicated between the mobile device and a fixed device, can determine whether there is a loss or theft by comparing surveillance target information and a permission standard, and can provide alert information including the location information of the surveillance target when the loss or theft occurs.
摘要:
A supporting device for a display unit for rotating a display screen to be oriented vertically. The supporting device includes a fixed member mounted on a base, an elevating member secured to the fixed member to be lifted or lowered, a pivot bracket rotatably coupled to an upper end of the elevating member while being secured to a rear surface of the display unit, an operating lever having an upper portion rotatably coupled to the upper end of the elevating member, a holder formed at the fixed member to allow the operating lever to be caught therein when being rotated rearward in a lifted state of the elevating member, a horizontally movable member secured to the upper end of the elevating member, and a cam portion formed at the pivot bracket.
摘要:
A display apparatus having a casing in which an opening part is formed, includes: a liquid crystal display panel that is supported by the casing so that an image can be displayed through an opening part; a backlight unit that is provided behind the liquid crystal display panel and has a light source that emits light; a shield cover that is provided behind the backlight unit and is supported by at least one of the backlight unit and the casing; and a cooling fan unit that is combined to the shield cover and supplies cooling air to the backlight unit.
摘要:
Provided are a memory device that undergoes no structural phase change, maintains a uniform thin film, and can perform a high-speed switching operation, and a method of operating the same. The memory device includes a substrate, an abrupt MIT material layer, and a plurality of electrodes. The abrupt MIT material layer is disposed on the substrate and undergoes an abrupt metal-insulator transition by an energy change between electrons. The plurality of electrodes are brought into contact with the abrupt MIT material layer and are melted by heat to form a conductive path on the abrupt MIT material layer.
