A liquid crystal cell in which the electrodes are patterned with small scale non-conducting gaps so as to efficiently control the number, size and location of liquid crystal domains within which the liquid crystal exhibits an azimuthal orientation with predominantly the same sign and direction in a field-on condition. A fluid suction port and a discharge port are defined by the housing and the suction port is in fluid communication with a fluid reservoir of the input source. The first portion is for placement in direct contact with and to be surrounded by an electrolyte. The privileges may include the ability to control the robot, joint in a multi-cast session and the reception of audiovideo from the robot. 1-D processing makes the implementation easy while the top-down multiscale dot assignment can produce a multi-resolution halftoned image, which provides a good approximation of the original in multiple scales. In one embodiment, the magnetic permeable material is shaped as a pin which is press-fit into the core of a helix-shaped inductor embedded in the package substrate.
