Abstract: Systems and methods are described herein to control brightness based on image content or other inputs to a display system. A dual-control system may integrate both slow control operations and fast control operations into a cohesive brightness management system. By using both shorter-term (e.g., fast control) and longer-term (e.g., slow control) brightness adjustment operations, the electronic device may quickly respond to high luminance and high brightness situations that may cause burn-in into the display, image artifacts, or other damage. Responding quickly to these high consumption situations may prevent damage or perceivable upset to an ongoing process, among other benefits.

Abstract: A facemask includes integrated actuating modules having sensors and other mechanisms. The facemask has one or more sockets into which various modules may be inserted. The facemask itself or the modules may include air filters and check valves to regulate airflow along or through the various modules. The modules may detect various substances either in the ambient air or the air exhaled by the wearer. The facemask also includes modules for measuring pulmonary and/or cardiovascular exertion, lung capacity and other physiological metrics. Other modules may provide supplements, vitamins or other substances such as tobacco smoke or vapor from vaporizers to the wearer. The modules may include microcontrollers in wireless communication with software applications on electronic devices so that the facemask may also serve as a cellular phone.
