Abstract: A system, method and computer program product for operating a low-voltage Internet-of-Things sensor device. The method includes sensing of the temperature dependence at each voltage condition in addition to the actual temperature and voltage. A programmed machine learning model uses the information to decide when it is appropriate to test the device functionality and use the results of different tests to determine when the system should run synchronously or asynchronously through a machine learning predictive algorithm. Based on said one or more sensed operating conditions, the system uses the model to detect a mode of operation of said IoT device indicating IoT device meets an expected level of performance, or a mode indicating said IoT device is not operating according to the expected level of performance. Based on the detected operating condition, the IoT device automatically adapts its operation to ensure a desired level of IoT sensor device performance.

Abstract: Systems and methods are provided for adaptively powering an Information Handling System (IHS) using a multimode AC adapter. Information reported by the multimode adapter is utilized to determine whether it supports USB-PD power transmissions and also supports high-power transmissions. The power demand of the IHS is monitored. When the power demand is greater than the USB-PD power levels, the multimode adapter is configured for providing a high-power transmission and a power circuit of the IHS is configured for converting the high-power transmission to a voltage used by the IHS. When the power demand is not greater than the USB-PD power levels, the multimode adapter is configured for providing a USB-PD transmission. Some embodiments may detect events associated with high power demand and may preemptively configure the power circuit of the IHS for providing high-power outputs upon detecting such events.

Abstract: Systems and methods employ an external energy storage device (e.g., intelligent battery pack) interposed between a an information handling system (IHS) and its AC-to-DC adapter.

The external energy storage device may actively signal or command the IHS to act or may passively supply power state information and let the IHS decide how to act.
