    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： For mechanical keyboards or other input devices with individual mechanical key buttons, and particularly for compact keyboards used for laptops and other such devices, the size of the up and down arrow keys is usually half the size of most other keys on the keyboard. For example, each letter key on a physical keyboard is typically double the size of each of the up and down arrow keys on that same keyboard. Due to the smaller physical size of the up and down arrow keys, a modified mechanical configuration is used which results in a variation in the tactile feel of the various buttons of the keyboard for a user. The present disclosure discloses a capacitive touch enabled key with a corresponding tactile button to allow the key to represent multiple different inputs while also maintaining a same tactile response as other single input keys of the input device.
