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.

Claims

exact text as granted — not AI-modified
1 . A data translation system ( 100 ) for performing a non-linear data translation on a digitized AC signal, the translation system ( 100 ) comprising:
 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 and 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.   
     
     
         2 . The data translation system ( 100 ) of  claim 1 , wherein the predetermined transfer function creates the non-linearly translated signal with respect to a predetermined reference point. 
     
     
         3 . The data translation system ( 100 ) of  claim 1 , wherein the predetermined transfer function is configured to alternatively compress or amplify digital values of the digitized AC signal. 
     
     
         4 . The data translation system ( 100 ) of  claim 2 , wherein the predetermined transfer function is configured to alternatively compress or amplify digital values of the digitized AC signal in relation to a distance from the predetermined reference point. 
     
     
         5 . The data translation system ( 100 ) of  claim 1 , wherein the non-linear data translation substantially preserves a phase information in the non-linearly translated signal. 
     
     
         6 . The data translation system ( 100 ) of  claim 1 , wherein the non-linear data translation preserves a zero-crossing information in the non-linearly translated signal. 
     
     
         7 . The data translation system ( 100 ) of  claim 1 , wherein the non-linear data translation substantially reduces a signal bandwidth of the non-linearly translated signal. 
     
     
         8 . A data translation method for a digitized AC signal, the method comprising:
 receiving the digitized AC signal;   non-linearly translating the digitized AC signal using a predetermined transfer function to create a non-linearly translated signal; and   transferring the non-linearly translated signal.   
     
     
         9 . The method of  claim 8 , wherein the predetermined transfer function creates the non-linearly translated signal with respect to a predetermined reference point. 
     
     
         10 . The method of  claim 8 , wherein the predetermined transfer function is configured to alternatively compress or amplify digital values of the digitized AC signal. 
     
     
         11 . The method of  claim 9 , wherein the predetermined transfer function is configured to alternatively compress or amplify digital values of the digitized AC signal in relation to a distance from the predetermined reference point. 
     
     
         12 . The method of  claim 8 , wherein the non-linear data translation substantially preserves a phase information in the non-linearly translated signal. 
     
     
         13 . The method of  claim 8 , wherein the non-linear data translation preserves a zero-crossing information in the non-linearly translated signal. 
     
     
         14 . The method of  claim 8 , wherein the non-linear data translation substantially reduces a signal bandwidth of the non-linearly translated signal. 
     
     
         15 . 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.   
     
     
         16 . The optocoupler transmission system ( 900 ) of  claim 15 , 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. 
     
     
         17 . The optocoupler transmission system ( 900 ) of  claim 15 , 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. 
     
     
         18 . The optocoupler transmission system ( 900 ) of  claim 15 , wherein the optocoupler transmission system ( 900 ) includes at least two devices ( 905 ,  907 ) communicating through the optocoupler ( 115 ). 
     
     
         19 . The optocoupler transmission system ( 900 ) of  claim 15 , wherein the optocoupler transmission system ( 900 ) implements a master-slave communication scheme. 
     
     
         20 . 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.   
     
     
         21 . The method of  claim 20 , 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. 
     
     
         22 . The method of  claim 20 , 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.
