Patent ID: 8175087

Claim:
A method for serially sending data signals from multiple sources through a single unidirectional isolation component, comprising the steps of: capturing, in parallel, the data signals from respective multiple sources; storing each of the captured data signals in a corresponding storage; transferring, in serial, the stored captured data signals in corresponding storage to the single unidirectional isolation component, performing two or more concurrent processes for parallel data signal capture and serial data signal transfer to the single unidirectional isolation component so that the sampling effect on a first of the processes is minimized, the first of the processes being initiated when a first input data signal is detected, and a second process being initiated when a second input data signal having a lower priority than the first input data signal is detected, and independently supplying first and second timing signals to handle the first and second processes, respectively, the first timing signal being activated when a change in the first input data signal is detected.
