摘要： In example implementations, an apparatus is provided. The apparatus includes a riser card body, a first interface, a first 2×8 slot on a surface of the riser card body, and a second 2×8 slot on a same side of the surface of the riser card body as the first 2×8 slot. The first interface includes a first set of fingers and a second set of fingers at an end of the riser card body to connect to a peripheral component interconnect express (PCIe) slot of a motherboard. The first 2×8 slot and the second 2×8 slot are positioned perpendicular to the PCIe slot of the motherboard.

摘要： In some examples, an electronic device includes an audio output device, an airflow generator to generate an airflow, and a system controller to control an operational speed of the airflow generator. The electronic device further includes an audio controller to generate a noise cancellation audio output based on an indicator of the operational speed of the airflow generator provided from the system controller to the audio controller, and send the noise cancellation audio output to the audio output device to mitigate noise produced by the airflow generator.

摘要： In one example, touchpad assembly is disclosed, which may include a bottom cover, a horizontal elastic member flexibly positioned on the bottom cover, a balancing bar disposed on the bottom cover and substantially parallel to the horizontal elastic member, and a metal dome. The metal dome may include a first end fixedly connected to the bottom cover via a first fixture, and a second end to hold the horizontal elastic member and the balancing bar such that the balancing bar is flexibly engaged with the bottom cover. The balancing bar, the metal dome, and the horizontal elastic member may control a flexure of a touchpad when the touchpad is pressed.

摘要： In example implementations, a computing device is provided. The computing device includes a system management bus, a controller communicatively coupled to the system management bus, a noise generating component communicatively coupled to the controller, a noise cancellation codec communicatively coupled to the system management bus, and a speaker communicatively coupled to the noise cancellation codec. The operating parameters of the noise generating component are provided to the controller. The noise cancellation codec is to receive the operating parameters of the noise generating component from the controller via the system management bus and to generate a noise cancellation signal based on the operating parameters. The speaker outputs the noise cancellation signal to cancel noise generated by the noise generating component.

摘要： In example implementations, a computing device is provided. The computing device includes an expansion interface that includes a plurality of slots. A first add-in card is connected to a first slot of the plurality of slots. A second add-in card is connected to a second slot of the plurality of slots. The computing device includes a processor communicatively coupled to the expansion interface. The processor is to detect that the first add-in card is compatible with a power savings control signal and that the second add-in card is not compatible with the power savings control signal, disable the power savings control signal to the second slot, and transmit the power savings control signal to the first slot when the first add-in card goes into a power savings mode.

摘要： Structures and functions of power supplies are disclosed. In an example, a power supply includes a power factor correction circuit and a bypass circuit. The bypass circuit bypasses the power factor correction circuit when the switch of the bypass circuit is on in response to a predetermined range of input power of the power supply. The bypass circuit also includes a delay circuit to delay the activation of the bypass circuits in response to the predetermined range of input power of the power supply for a predetermined time period.
