Claim Text:
1. A method comprising: providing, to a first resistor of a combiner circuitry, a driving signal having a first current from a light emitting diode driver circuitry, the combiner circuitry comprising a second resistor, a current controller, and an operational amplifier including a first operational amplifier input and a second operational amplifier input; providing the driving signal to the first operational amplifier input, the first resistor coupled to the first operational amplifier input; providing, to the current controller, a boost signal having a second current from at least one of a capacitor or a battery; controlling, by the operational amplifier, the current controller via an operational amplifier output signal; selectively providing, by the current controller, the boost signal to the second operational amplifier input and the second resistor, the second resistor coupled to the second operational amplifier input; producing, by the first resistor, a first current component based at least in part upon the first current and a first value of the first resistor; producing, by the second resistor, a second current component based at least in part upon the second current and a second value of the second resistor; combining, by the combiner circuitry, the first current component with the second current component to form an augmented current; and outputting, by the combiner circuitry, the augmented current to drive at least one light emitting diode.
