Abstract: In some implementations, a measurement circuit may drive, using a first transistor, a first node of a haptic load. The measurement circuit may trigger a first comparator when a voltage driving the haptic load satisfies a first condition. The first comparator may have a first node connected, in parallel, to a drain of a second transistor and may have a second node connected to the first node of the haptic load. Additionally, the second transistor may have a gate connected to a gate of the first transistor and may have the drain connected to a first reference current.

Abstract: Systems and methods for illuminating a subject for image capture are described herein. A processor may determine an ambient color temperature of a subject. The processor may further determine a color temperature for outputting light from a display facing a first direction based on a light output characteristic for a dedicated illumination element facing the first direction, the determined ambient color temperature, and a desired color temperature of the subject. The processor may further illuminate the subject using both the dedicated illumination element and the display. The display may output light based on the determined color temperature for outputting light from the display. The processor may further capture, using an image sensor facing the first direction, an image of the subject during the subject being illuminated using both the dedicated illumination element and the display.
