Abstract: In one exemplary embodiment, a method includes the step of obtaining a digital image of a user with a user-facing camera of a computing device. It is determined that the digital image includes a frontal image of the user. A user-sentiment score is calculated based on at least one attribute of the frontal image. A user engagement value is determined with respect to a portion of a display of the computing device. At least one of the frontal image of the user, the user-sentiment score or the gaze position of the user is communicated to an external server process or an application operating in the computing device.

Abstract: In one aspect, a thermal management system of rechargeable battery system includes a plurality of rechargeable electrochemical batteries installed in a rechargeable battery pack. The system includes a cooling pump that circulates a liquid coolant mixture through the pipe. The pipe runs through the battery pack and a thermo-electric heater/cooler system, and wherein cooling pump controls a flow speed of the cooling liquid through a pipe that absorbs heat from the plurality of rechargeable electrochemical batteries in each circulation through the pipe. A reservoir holds the liquid coolant mixture and maintains a specified pressure through the pipe. A thermal management system block includes a computing system, computer memory, a computer networking system, and a Pulse-width modulation (PWM) Controller. The PWM Controller is connected with the cooling pump and controls the cooling pump pumping speed to meet the acceptable temperature range in the rechargeable battery pack.
