Electrical appliances and system responding to timing and synchronizing data, uses unit sending out time data and synchronizing signals to programme and synchronize appliance controller

摘要

The electrical system has two components: one (40) sending out programming time data and a synchronization signal, and the other (2) receiving (16) and recording programming time data, and producing an action in response to a time mark in the programming data. The receiving unit can also synchronize with an external time reference to correct its own time measurement.
