Simultaneous data and electric power transmitting/receiving system
First Claim
1. A data and power transmitting/receiving system comprising:
- a plurality of terminal means (20A . . . 20N) selectively operable for producing specific data (40) for utilization by the respective terminal means;
a plurality of communication means (10A . . . 10N) connected to the corresponding terminal units, including;
at least a sync signal generator for generating a sync signal and superimposing the sync signal on the specific data in a time-division mode to produce a data signal (45), anda data processing unit (4A . . . 4N) operative for processing the data signal to determine a controlling condition of the respective terminal means (20A . . . 20N) and for producing power for driving the data processing units; and
a common signal transmission line (30) for connecting said plurality of communication means so as to communicate the data signal with the communication means, whereby simultaneous data transmission and reception are carried out between the communication means.

Abstract
A data and power transmitting/receiving system applicable to a home automation system. Plural terminal units and associated communication units are connected via a common signal bus. Each terminal unit may operate an electrical load to be controlled remotely, and may include control switches for operating such loads at a number of remote locations. Each communication unit generates an n-bit data signal, each bit corresponding to the desired function of a corresponding terminal unit. A sync signal is combined with the data signal in time sequence such that the respective communication units can identify which signal operates which terminal unit. The sync signals also can supply DC power to ther respective communication units.
