This disclosure provides novel latching circuits, and pixel circuits and display devices that include such latching circuits. When an H-ARQ attempt is unsuccessful due to loss or error over a hop between the BS and MSSS, then only the first node in the hop chain that fails to decode the packet transmits another H-ARQ attempt. The script may be stored on a server, on the desktop, or on a removable media, such as an optical or magnetic diskette. The cup is subsequently rotated through a second angle in the second plane.
