Patent ID: 8710771

Claim:
A method for adjusting duty cycles of remote control illumination sources, the method comprising: directing, utilizing at least one processing unit, illumination of at least one illumination source of a remote control device according to at least one duty cycle wherein the at least one duty cycle defines a first portion of time that power is provided to the at least one illumination source from at least one battery and a second portion of time that power is not provided to the at least one illumination source from the at least one battery; monitoring, utilizing the at least one processing unit, at least one voltage output by the at least one battery that provides the power to the at least one illumination source; and adjusting the duty cycle based at least on the monitored at least one voltage, utilizing the at least one processing unit, to increase a duration of the first portion of time based at least on a decrease of the monitored at least one voltage compared to a maximum voltage level.
