The first mobile elements (RPP1) transmit broadcast information to the second mobile elements.

There may be multiple moveable elements.

The movable members move in conjunction with the holders set to the accommodating parts.

The mobile elements are exchangeable between adjacent groups.

Portions of the composite structure are patterned and etched to define stationary and movable MEM elements, with the movable elements being mechanically coupled to the stationary elements.

The movable members (14) are slidably displaceable in a plane parallel with the fixed members (11).

The mouth section (1) may have movable parts.

The moveable members are capable of varying a configuration of the aperture.

The movable elements are represented by animals, selectively horses.

The moveable elements may include flexible elements, elements having constructed to have a memory of a native position, magnetic elements, and/or elastic elements

The invention can be designed in modularization and used conveniently; the amount of moving components can be reduced, which can avoid the interference among moving components.

Sealing means may be included to prevent fluids from contaminating the inner regions of the flexible body, and may be adapted to bias the movable elements to a preferred orientation.

An address signal to said at least one movable element is provided.

Mobile Elements is a family of mobile and multi-purpose tools.

A set of actuating components are coupled to movable elements of an active container, the movable elements respond to operation of an actuating mechanism in a handle portion.
