Abstract: A power subsystem is configured to manage the maximum power usage of a computer subsystem. A power detector determines when power usage approaches the maximum capability of the power supply. The power detector generates a signal that corresponds to power usage. A controller then applies the signal to the system voltage regulator as a secondary regulation function such that the output voltage is reduced in a manner that supports maximum operating voltage while limiting power usage to within the capability of the power supply. The controller may configure the signal to implement the secondary regulation function as a modification of the feedback voltage, the reference voltage, or the current feedback of the regulator. As a result the subsystem causes the computer subsystem to operate at an optimum point on the voltage-current curve of the power supply.

Abstract: The disclosure provides a cooling solution that evaluates the thermal environment of a computer component based on transient thermal responses of the computer component. The transient thermal responses are generated by measuring the temperature rise of the computer component over a designated amount of time for multiple “good” assemblies and multiple “bad” assemblies to determine a duration and allowable temperature rise needed to set a pass/fail criteria for different failure modes of cooling devices. A cooling device may not be operating as designed due to damage, needed maintenance, missing thermal interface material (TIM), improper installation, etc. From the transient thermal responses, a thermal problem, such as a malfunctioning fan, can be determined and a corrective action can be performed.

Abstract: System and method of controlling an object via control device having integrated touch and displacement control. An embodiment includes an input device having a control stick with an integrated touch sensor, where the control stick may be displaced to provide control of a first functionality of an object, and a user touch sensed by the integrated touch sensor provides control of a second functionality of the object. Additionally, a method is described for controlling an object using a control device integrating displacement and touch control modes. A motion of the object may be controlled, such that inputs from the control device control a relative movement, an absolute movement, and/or a combination of relative and absolute movement for the object. An embodiment includes a game controller having a control device according to the present disclosure.
