An integrated circuit is described. At least one of the player game pieces may have an advantage over one or more of the other player game pieces. The drain plug may be configured for draining various sized canned goods. The first and second hinge arms cooperate to define an elongated hinge pin-receiving receptacle. For example, overhangs between phosphor components and circuit boards in the package can be avoided, thereby ensuring that the final lighting system will provide any desired emission angles. When the locking unit is unlocked, the elastic unit releases the elastic potential energy to push the port chip to be detached from the receptacle chip.
