Abstract

A data translation system (100) for performing a non-linear data translation on a digitized AC signal is provided. The non-linear data translation system (100) includes an input for receiving the digitized AC signal, an output for outputting a non-linearly translated signal, and a processing system (104) coupled to the input and to the output. The processing system (104) is configured to receive the digitized AC signal, non-linearly translate the digitized AC signal using a predetermined transfer function to create the non-linearly translated signal, and transfer the non-linearly translated signal to the output.

First claim

What is claimed is:

1. An optocoupler transmission system ( 900 ) for controlling signal transmission through an optocoupler transmission medium, the optocoupler transmission system ( 900 ) comprising:
an optocoupler ( 115 ); and
a controller ( 920 ) coupled to the optocoupler ( 115 ) and configured to receive a transmit attempt from a first device ( 905 ), determine if a second device ( 907 ) is already transmitting through the optocoupler ( 115 ), determine if receiving the transmit attempt is outside a deadband period after a power-up occurrence, and transmit from the first device ( 905 ) through the optocoupler ( 115 ) if the second device ( 907 ) is not transmitting and if the deadband period has elapsed.

2. The optocoupler transmission system ( 900 ) of claim 1 , with the controller ( 920 ) being further configured to hold off the first device ( 905 ) from transmitting through the optocoupler ( 115 ) until the second device ( 907 ) has completed transmission if the second device ( 907 ) is already transmitting.

3. The optocoupler transmission system ( 900 ) of claim 1 , with the controller ( 920 ) being further configured to hold off the first device ( 905 ) from transmitting through the optocoupler ( 115 ) until the deadband period has elapsed if the transmit attempt is within the deadband period.

4. The optocoupler transmission system ( 900 ) of claim 1 , wherein the optocoupler transmission system ( 900 ) includes at least two devices ( 905 , 907 ) communicating through the optocoupler ( 115 ).

5. The optocoupler transmission system ( 900 ) of claim 1 , wherein the optocoupler transmission system ( 900 ) implements a master-slave communication scheme.

6. A transmission control method for controlling signal transmission through an optocoupler transmission medium, the method comprising:
receiving a transmit attempt from a first device;
determining if a second device is already transmitting through the optocoupler transmission medium;
determining if receiving the transmit attempt is outside a deadband period after a power-up occurrence; and
transmitting from the first device through the optocoupler transmission medium if the second device is not transmitting and if the deadband period has elapsed.

7. The method of claim 6 , further comprising holding off the first device from transmitting through the optocoupler transmission medium until the second device has completed transmission if the second device is already transmitting.

8. The method of claim 6 , further comprising holding off the first device from transmitting through the optocoupler transmission medium until the deadband period has elapsed if the transmit attempt is within the deadband period.

9. The method of claim 6 , wherein the optocoupler transmission medium includes at least two devices communicating through the optocoupler transmission medium.

10. The method of claim 6 , wherein the method implements a master-slave communication scheme.
