The board-to-board connector comprises an insulating housing and a plurality of terminals. So that the parking brake system or its electromechanical actuating unit only needs to cope with relatively small load situations, it is proposed that, when, for certain operating conditions, the parking brake system has to maintain brake forces which are greater than the brake forces it is able to generate itself, the service brake system generates the additionally required brake forces. The first voltage setting circuit sets the bit line to a first voltage, and the second voltage setting circuit sets the sense node to a second voltage. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. The device comprises an anchor having a cannula and a locking mechanism for securing the suture within the cannula.
