A construction liner for sportsball, such as an American football, which is made by compressing and vulcanization a rubber piece with at least a fabric lining, is strong enough to produce a more durable American football with better supporting but lower manufacturing cost. An exemplary embodiment of the device includes a housing structure, and a primary electrical power connection connected to the housing structure and including a primary wiring cable for connection to a line voltage source. The base includes a conduction mechanism therein. As a result, unnecessary delay time is reduced in memory block activation, thereby improving operation speed.
