Abstract: A pouch-type battery case according to an embodiment of the invention may accommodate an electrode assembly, in which electrodes and separators are alternately stacked. The pouch-type battery case may include: a pair of recess parts, each of which has a recessed shape; a pair of terraces that are disposed around the pair of recess parts and are inclined downward in a direction closer to each other in a state; in which the battery case is unfolded; and a bridge disposed between the pair of recess parts, configured to connect the pair of recess parts to each other, having a pair of connection surfaces formed to be inclined upward from a bottom surface of each of the pair of recess parts in a direction closer to each other. In the state in which the battery case is unfolded, an angle formed by the pair of terraces may be an obtuse angle.

Abstract: A method and a system for sensing engine oil deterioration are disclosed. The method includes measuring an engine RPM, load (Load), and an engine temperature (Temp), calculating the amount of change in a deterioration factor (f (RPM, Load, Temp) of engine oil per revolution of an engine using the measured engine RPM, load, and the engine oil temperature, and then calculating the engine oil deterioration degree at a current time point by accumulating a value obtained by multiplying the calculated amount in change of the deterioration factor (f (RPM, Load, Temp) by an engine revolutions during a predetermined sampling cycle (?r) to a previous engine oil deterioration degree.

Abstract: The present invention relates to a membership processing method comprising the steps of: enabling a franchise information processing device to receive franchise registration request information of a customer for registering a particular company as a franchise and to transfer the franchise registration request information to a corresponding company terminal; mapping corresponding company information with information on the customer who has requested the franchise registration, and classifying and registering the company information as the franchise of the corresponding customer; receiving a notification message including customer benefit information from a predetermined company terminal; and transferring the notification message including the customer benefit information to a client terminal of the corresponding customer, if the company which has transmitted the notification message is a registered franchise.
