摘要： Key assemblies are disclosed herein that are retractable and/or that present a variable key assembly depression force to a user. In one example, one or more key assemblies may be provided that each employ one or more electro-permanent magnets (EPMs) together with permanent magnet and/or magnetically permeable (e.g., ferromagnetic) key assembly components to control key retraction and extension, and/or to control peak depression force (e.g., typing force) required to depress and displace a key assembly from an extended position to a lower position that causes the key assembly to produce a digital or analog output signal.

摘要： Systems and methods are disclosed herein that may be implemented to configure, provide and operate retractable key assemblies and/or key assemblies that present a variable key assembly depression force to a user. In one example, key assemblies may be provided that each employ one or more electro-permanent magnets (EPMs) together with permanent magnet and/or magnetically permeable (e.g., ferromagnetic) key assembly components to control key retraction and extension, and/or to control peak depression force (e.g., typing force) required to depress and displace a key assembly from an extended position to a lower position that causes the key assembly to produce a digital or analog output signal.

摘要： An information handling system may include a first member, a second member hingedly coupled to the first member via a hinge, a coaxial cable, and a grounding jacket. The coaxial cable may have a ground sheath and a signal wire internal to the ground sheath, wherein an axis of the signal wire is substantially parallel to a rotational axis of the hinge and wherein the coaxial cable comprises an exposed portion in which the ground sheath is exposed externally to the coaxial cable. The grounding jacket may be mechanically coupled to the first member and the second member, wherein the grounding jacket may be configured to mechanically support the coaxial cable and electrically couple to an electrically conductive portion of at least one of the first member and the second member and to the ground sheath at the exposed portion in order to create an electrically conductive path between the ground sheath and the electrically conductive portion via the grounding jacket.
