Abstract: A hinge device for supporting an electronic device includes a first portion and a second portion movable relative to the first portion with a biasing element supported by one or the first portion or the second portion. The first portion has an arcuate groove, and the second portion has an arcuate rail configured to complementarily mate with the arcuate groove and slide therein. The biasing element contacts a leading edge of the other of the first portion or second portion, and the first portion and second portion are bistable in a closed state relative to one another and an open state relative to one another based at least partially on a surface profile of the biasing element applying a radial force to the leading edge.

Abstract: Examples are disclosed relating to computing device hinge assemblies. In one example, a hinge assembly comprises a hinge frame affixed to one substrate and a hinge arm member affixed to another substrate. The hinge arm member comprises first and second arcuate arm guide slots. An arm support member, moveably coupling the hinge arm member to the hinge frame, comprises a first side comprising a first arcuate support guide slot receiving a first frame guide of the hinge frame, and a second side comprising a second arcuate support guide slot receiving a second frame guide. First and second arcuate inner support guides are received within the first and second arcuate arm guide slots of the hinge arm member. An elongated bridge member connects the first side of the arm support member to the second side, with the bridge member comprising a unitary structure fabricated from bulk metallic glass.

Abstract: The described technology provides a hinge device including a band including a first band end coupled by a slidable rotatable coupling to a first panel and a second band end coupled by a rotatable coupling to a part of a central support section and a different band including a first different band end coupled by a different slidable rotatable coupling to a second panel and a second different band end coupled by a different rotatable coupling to a different part of the central support section, wherein the central support section is configured to rotate around a virtual pivot axis parallel to each of the first panel and the second panel and located outside a surface plane of each of the first panel and the second panel.

Abstract: An impeller for a centrifugal blower includes at least one blade oriented in a radial direction of the impeller. The blade has an airfoil section with a radially inward end and a radially outward end that are thinner than at least one point between the radially inward end and the radially outward end.
