Methods, devices and systems for synchronizing actions taken by digital devices in a group wherein the digital devices to use a flocking protocol to establish time or behavior synchronization between individual digital devices within the group. The flocking protocol includes the transmission of synchronization information from one device to neighboring devices within the group and the processing/use of such synchronization information by the devices to synchronize the timing and/or other characteristics of their actions.

An electric system comprising communication link between a signal transmitting end and a signal receiving end, wherein, at the signal transmitting end, a number of data bits are integrated into a low frequency signal to form an integrated signal. Each data bit is transmitted as part of a symbol. Each symbol comprises a predefined number of bits encoding at least one data bit, the state of some of the bits of each symbol being dependent on the state of the low frequency symbol.
