Abstract: A sterilizing unit for a brush simultaneously moves an ultraviolet light source under a brush head to kill bacteria on the bristles with UV light, and also separates the bristles from each other to remove dirt and debris from between the bristles.

Abstract: A system and method is provided for use with a mobile electronic device (e.g., mobile phone, such as a smartphone) that tracks the amount of time the mobile electronic device is used by the user (e.g., employee) during a period of time (e.g., during a work shift at a workplace) to minimize or eliminate distractions from said mobile electronic device in order to improve the efficiency of the user (e.g., employee). The system and method provides a quantitative analysis of the efficiency of the user during said period of time and/or a quantitative analysis of the number of times the user (e.g., employee) interacts with their phone (e.g., during a work period).
