A projectile, air vehicle or submersible craft with a spinning or rolling fuselage, rotating on its axis, has a collar which can be positioned relative to a longitudinal axis of the projectile using aerodynamic forces. The first and second frame member are positioned above and below a first light emission face and a second light emission face of the light guide plate, respectively. A first circuit block is connected to the first terminal and the first power supply terminal, and receives data output from the host device based on the first power supply voltage. The invention is applicable to mascara. A method for wireless relay network communications includes determining performance information regarding a plurality of relay nodes, allocating resource blocks in a subframe to relay nodes based on the information, and notifying relay nodes of the allocated RBs using a signaling message. Analog and digital re-alignment circuits reduce internal skew.
