Abstract: A three-dimensional semiconductor integrated circuit device including an inter-die interface is provided. The device includes a top die including a plurality of micro cells provided on a top surface of the top die, a plurality of micro bumps provided on a bottom surface of the top die, and wiring patterns connecting the plurality of micro cells to the plurality of micro bumps; and a bottom die including a plurality of macro cells provided on a top surface thereof, wherein the plurality of macro cells are electrically connected to the plurality of micro bumps, respectively, wherein a size of a region in which the plurality of micro cells are provided is smaller than a size of a region in which the plurality of micro bumps are provided.

Abstract: Elevator-type systems for a toy vehicle and toy vehicle track sets are disclosed. The elevator-type system may include a carriage configured to receive a toy vehicle, the carriage is configured to move between a first position and a second position. The elevator-type system may additionally include a tension rope having a first end and a second end, the first end is attached to the carriage. The elevator-type system may further include a counterweight attached to the second end. The weight of the counterweight may be greater than the weight of the carriage to bias the carriage toward the first position. The weight of the counterweight may be less than the weight of both the carriage and a toy vehicle received in the carriage to allow the carriage to move toward the second position when the toy vehicle is received in the carriage.

Abstract: A toy vehicle track set is provided including a first track portion and a second track portion. The second track portion is distal from the first track portion. The first track portion and the second track portion define a gap therebetween. The toy vehicle track set also includes a pair of separately rotating arms. The rotating arms cooperate to transfer a toy vehicle across the gap from the first track portion to the second track portion. When the toy vehicle is released at the second track portion, the toy vehicle may traverse along a path of the track set from the second track portion to the first track portion.

Abstract: A track set is provided, the track set having: a toy vehicle; a toy airplane; a launcher for launching the toy airplane; a trigger mechanism coupled to the launcher, wherein the trigger mechanism is located in a portion of a track path of the track set; and wherein actuation of the trigger mechanism by the toy vehicle as it travels along the track path launches the toy airplane from the launcher towards an indicator mechanism configured to be contacted by the toy vehicle traveling along the track path and the toy airplane after it has been launched from the launcher.

Abstract: A toy vehicle track set is provided including a pair of arm members including a first arm member and a second arm member. The pair of arm member are movably mounted to the track set for movement between a first position and a second position. A toy vehicle carriage is pivotally mounted at a distal end of each of the pair of arm members. Each of the pair of arm members is coupled to one another such that as one of the arm members moves from its first position to its second position, the other of the arm members also moves from its first position to its second position.
