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:
A dynamic multiple input rail switching unit includes a plurality of DC input voltage rails and a rail switching section coupled to the plurality of DC input voltage rails that is configured to individually connect selected ones of the plurality of DC input voltage rails to a switched rail output. The dynamic multiple input rail switching unit also includes a rail selection section that is coupled to the rail switching section and configured to dynamically choose the selected ones by balancing rail supply currents from the plurality of DC input voltage rails based on rail supply current capacity margins and a switched rail output current. A dynamic multiple input rail switching unit operating method, and a dynamic multiple input rail power converter are also provided.

Abstract:
A display refresh system, method and computer program product are provided. In use, at least one aspect of a display of content is identified by monitoring commands. Based on such identified aspect(s), a refresh rate of a display utilized for the display of the content may be adjusted.
Abstract:
A graphics subsystem includes a printed circuit board (PCB), a blower, and a heat sink. A graphics processing unit (GPU) is integrated into the PCB. The PCB is shortened to occupy a portion of the width of the graphics subsystem. The heat sink is coupled to the PCB and/or GPU similarly occupies just a portion of the width of the graphics subsystem. The blower is disposed adjacent to the PCB and heat sink and configured to occupy the full height of the graphics subsystem. The blower is further configured to intake air from both the top side of the graphics subsystem and the bottom side of the graphics subsystem. In this configuration, the blower provides an elevated air flow rate in order to facilitate cooling of the PCB and/or GPU.
Abstract:
A computing device comprises: a base portion; a display portion that is movably coupled to the base portion and includes a housing having a movable panel and one or more fixed panels; and a mechanical assembly that positions the movable panel away from the one or more fixed panels as the display portion opens away from the base portion.
Abstract:
A system, method, and computer program product are provided for merging two or more supply rails into a merged supply rail. The method comprises receiving two or more current measurement signals associated with two or more supply rails, selecting one supply rail from the two or more supply rails, based on the current measurement signals, and enabling the selected supply rail to source current into a merged supply rail.
