Abstract: An apparatus includes a first conductor connected to a pin of a controller, where the first conductor includes a low frequency first signal component, and second conductor with a high frequency second signal component. A coupling section includes part of the first conductor situated in proximity to part of the second conductor. The second signal induces an induced signal on the first conductor within the coupling section. The high frequency is at least an order of magnitude higher than the low frequency. The apparatus includes the controller with a first signal monitor configured to monitor the first signal present on the pin of the controller and to report a status of the first signal, and a second signal monitor configured to monitor the second signal by monitoring the induced signal present on the pin and to report a status of the second signal based on the induced signal.

Abstract: A system and a method include a control unit configured to control one or more fans of a computing device based on one or more fan curves. The control unit is configured to automatically adapt the one or more fan curves based on one or both of a current use of the computing device or one or more aspects of an environment in which the computing device is located.

Abstract: Systems and methods for use of magnets to retain and eject computing device expansion modules are disclosed. According to an aspect, a system includes a computing device that defines a slot for receipt of an expansion module for operable positioning of the expansion module with respect to the computing device. The expansion module comprises a first magnet attached thereto. Further, the system includes an electromagnet attached to the slot of the computing device. The system also includes a controller configured to apply an electrical output to the electromagnet such that the electromagnet generates a magnetic field for repelling the first magnet such the expansion module is urged in a direction for ejection from the slot.
