  • Patent number: 11495928
    Abstract: A power adapter has a solenoid actuated retaining latch controlled by an electronic circuit that detects the presence or absence of AC mains voltage. When the assembled AC-DC adapter and plug assembly are removed from the wall, the latch detects removal and unlocks the plug assembly for easy removal without undue force required by the user. The circuit is designed for minimal power consumption, and the solenoid only consumes power when it is engaging or disengaging the latch.

  • Publication number: 20210294397
    Abstract: A graphics subsystem includes a printed circuit board (PCB), a set of one or more fans, 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 and configured to extend beyond an edge of the PCB, thereby occupying a larger portion of the width of the graphics subsystem compared to the PCB. A first fan is disposed partially or fully beyond the edge of the PCB and is configured to direct air through the portion of the heat sink that extends beyond the edge of the PCB, along a first airflow path, and out of the graphics subsystem. A second fan is configured to direct air through the heat sink, along a second airflow path, towards the GPU.

  • Publication number: 20210298199
    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.

  • Publication number: 20180107253
    Abstract: A tablet computer and keyboard are coupled to a tablet computer case. The tablet computer case includes a dual-hinge suspension that allows the tablet computer case to open and close with similar mechanics as a laptop computer. In particular, the dual-hinge suspension includes two hinges that open and close sequentially in different phases. During a first phase of opening, the first hinge opens until a mechanical limit is reached while the second hinge remains stationary. In a second phase of opening, the first hinge is stationary while the second hinge opens until a mechanical limit is reached. During a first phase of closing, the second hinge closes until a mechanical limit is reached while the first hinge remains stationary. In a second phase of closing, the second hinge is stationary while the first hinge closes until a mechanical limit is reached.
