`rectifier?
`
`. Yes.
`
`. And so in this instance the half wave rectified signal
`includes only the positive pulses of the standard AC line
`voltage; correct?
`
`. That is correct.
`
`. And did you say that each of these pulses would have the
`same pulse duration coming out of the half wave rectifier?

`
`Q. And do you agree that when Hochstein is referring to simply rectifying,
`that it is referring to a half wave rectifier in the traffic signal controller?
`
`A. I do believe so.
`
`Q. And you would agree that a half wave rectifier outputs a fixed DC signal?
`
`A. It has an AC component to it, but it is a DC signal.

`
`Petitioner’s Construction
`
`Regly: “circuit for dimming a light source that receives an A.C.
`signal and controls power delivered to the light source”
`
`the ’399 patent clearly
`
`discloses the wavefonns shown being output from the dirmner circuit in
`
`Figure 1 are exemplary. Ex. 1001 at 1:64-2:16.
`
`Further, if the
`
`patentee intended to limit the output signals of the dimmer circuit to A.C.
`
`signals, it would have claimed an “alternating current (A.C.) power source
`
`that provides A.C. signals other than a standard A.C. line voltage,”
