A method for controlling and compensating aging in an LED device includes measuring a performance change in light output of the LED device. The LED device is controlled with a first compensation algorithm derived from the measured performance change, during a first period, to effect a luminance change over time in the light output of the LED device. Subsequently, a second compensation algorithm, derived from the measured performance change, and different from the first compensation algorithm, during a second period, effects a second luminance change over time in the LED device's light output. The second luminance change over time in the second period is different from the first luminance change over time in the first period. Furthermore, the first and second periods together are less than the lifetime of the LED device.

Methods, systems and devices for controlling mobile device functions via a combination of parental control settings set by a parent-user and parental control settings set by a third party-user. A parental control server receives parental control settings and context criteria from a parent-user, and parental control settings from a third party user. The parental control server receives authorization from the parent-user to allow third party parental controls to control a child's device. When the context criteria identified by the parent is present (e.g., child device is in identified location, time of day, day of week, etc.), a combination of parental controls designated by the parent-user and the third party control the mobile device.
