Abstract: A method for updating a subject avatar with a facial expression collected in real time. The method includes receiving, from a sensor on a facial interface of a headset, a signal indicative of a movement in a facial muscle from a user of the headset, determining a facial expression of the user with the signal from the sensor in the facial interface of the headset, based on a machine learning algorithm trained to associate the facial expression to the movement of the facial muscle, adjusting a subject avatar for the user of the headset based on the facial expression, and providing the subject avatar to an immersive reality application hosted by a remote server. A headset, a computer-readable medium storing instructions which, when executed by a processor cause the headset to perform the above method, and the processor, are also provided.

Abstract: Provided is a method of estimating temperature in a device including a main printed circuit board (PCB), a protection and control module (PCM), and one or more batteries electrically connected to the PCM. The method includes sensing a temperature of the PCB, via a PCB temperature sensor and sensing a temperature of the PCM via a PCM temperature sensor. The method also includes estimating a temperature of at least one of the batteries based on (i) the temperature determined via the PCB temperature sensor and (ii) the temperature determined via the PCM temperature sensor.
