Methods and systems are disclosed herein for a media guidance application that predicts user preferences based on detected events. The level sensor generates one or more measurement beam and directs the measurement beam to a measurement spot on the substrate and produces a reflected measurement beam. Flow channels for hydraulic fluid are provided to at least one of the sliding groove and the locking member, are formed along the sliding direction of the locking member, and are communicatingly connected to the concave engagement part. An arbitrating portion of the initiator object receives all bidding messages in a certain period of time, and, in consideration of parameters such as the bidding value and the communication time between objects, determines and awards the bid to the bid-winning object. Further, the scaled resource may be CPU, RAM, disk or any such resource.
