Power diverting circuit
First Claim
1. A power diverting circuit for creating a supply voltage for a signal processing circuit from a source of data signals each having a high or a low potential respectively corresponding to a first or a second logic state, said circuit comprising:
- a first terminal for receiving said data signals;
a second terminal at which said supply voltage is manifested;
switch means for selectively connecting said first terminal to said second terminal and disconnecting said first terminal from said second terminal;
an inverter for inverting the state of said data signals, said inverter having an input terminal connected to said first terminal and an output terminal for providing inverted data signals to said signal processing circuit; and
,connecting means connecting said inverter to said switch means whereby said inverter, in response to the state of said data signals received at said first terminal controls the operation of said switch means.

Abstract
The invention concerns a power diverting circuit for creating a supply voltage for a signal processing circuit from a source of data signals each having a high or a low potential respectively corresponding to a first or a second logic state. The circuit comprises a first terminal for receiving the data signals, a second terminal for providing the supply voltage, a switch coupled between the first terminal and the second terminal for selectively connecting and disconnecting the first terminal and the second terminal, and an inverter for inverting the state of the data signals. The inverter, which has an input terminal connected to the first terminal and an output terminal for providing the inverted data signals to the signal processing circuit, is responsive to the state of the data signals received at the first terminal to control the operation of said switch means.
