December 11, 2017 211 Opinion or Order of the Court Judge Denise J. Casper: ORDER entered. MEMORANDUM AND ORDER - For the foregoing reasons, the disputed claim terms are construed as follows: 1. the terms "input filter means" and "filter means" mean "a circuit that s electively transmits or rejects a signal in one or more intervals of frequencies conducted on the line input between the control unit and the converter"; 2. the term "means CM" means "a circuit, including a controlled semi conductor element, that draws leakage current from the control unit when the control unit is off";3. the term "removing a leakage current" means "drawing current that flows through a device in the off state";4 . the terms "self-regulating deactivating means for deactivating the means CM" and "self-regulating deactivating means for deactivating the means CM when the control unit is in a conductive state," mean "deactivating the mean s CM" for function and the structure is "transistor TM and zener diode Z60";5. the term "optical means for guiding the light emitted by the LED towards outside of the housing" means the function of "guiding the l ight emitted by the LED towards outside of the housing" and the structure as a "collimator";6. the term "means for sensing..." means for function, "sensing current to the LED array and generating a sensed current signal" and for structure, means "current sensor 60; resistor RiA1, R1A2 and/or R1A3 in Figure 2A; or resistor R1B1, R1B2, and/or R1B3 in Figure 2C";7. the term "means for generating..." means for function, "gen erating a reference signal," and for structure, means "reference current source 62; or the internal reference in PWM control IC 118 or 134";8. the term "means for comparing..." means for function, "comparing the sensed current signal to the reference signal and generating a feedback signal," and for structure, means "comparator 58; or the internal op-amp in PWM control IC 118 or 134";9. the term "means for modulating..." mean s, as to function, "modulating a pulse width responsive to the feedback signal and generating a drive signal" and for structure, means "pulse width modulation (PWM) control IC 56; PWM control IC 118; or PWM control IC 134";10. the term "means for supplying..." means, as to function, "supplying power responsive to the drive signal and supplying current to the LED array" and, as to structure, means "a buckboost, boost, buck or flyback power supp ly and its equivalent power supplies that regulate current (as opposed to regulating voltage)";11. No construction is necessary for the term "second LED"; and12. No construction is necessary for the term "signals other than a standard A.C. line voltage." (Hourihan, Lisa)
