    Abstract: Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.

    Abstract: Support systems and stands for electronic devices include tilt hinges, lift arms, and their component parts. Some tilt hinges include assemblies for guiding and retaining bars or protrusions into preferred positioning within receiver openings to unify the parts, particularly as they move, and to reduce wobble or slop in the joints. Lift arms provide simplified and low-cost guidance and counterbalance mechanisms for controlling movement of the electronic device relative to the base of a stand. In some cases, the lift arms have sheaths to help protect or cover mechanisms while allowing additional space for the mechanisms within the lift arm. Other interconnection systems hide and protect a connector interface between the stand and the electronic device within a housing until unlocked and the connector is moved into an exposed position. These systems improve efficiency, comfort, ergonomics, accessibility, and user satisfaction of the electronic devices and their supports.

    Abstract: A computer includes a processor, a PCIe-compatible interface bus that includes a root that is connected to the processor, and a routing complex that is connected to the root and is controlled by the processor. The computer also includes a first interface slot that is connectable to the root by the switches, a second interface slot that is connectable to the root by the switches, and an extended interface slot that is connectable to the root by the switches. The switches are configured based on properties of a first peripheral device to define a first switching configuration when the first peripheral device is connected only to the first interface slot and to define a second switching configuration when the first peripheral device is connected to both of the first interface slot and the extended interface slot.
