  • Patent number: 11739929
    Abstract: An information handling system may include one or more illuminable icons to present information to a user of the system, such as information regarding a status of the information handling system. An illuminable icon may be lit by a plurality of light sources, and light from the plurality of light sources may be diffused across the illuminable icon by a light guide film. Some illuminable icons may have multiple portions that may be separately illuminated to convey different information to a user. An isolation block may prevent light from light sources configured to illuminate one portion of an illuminable icon from illuminating other portions of the illuminable icon. Thus, light for illuminating icons of an information handling system may be diffused and/or blocked to enhance aesthetic appeal of the icons and to prevent user confusion that may result from bleeding of light from one portion of an illuminable icon to another and/or uneven illumination of an icon.

  • Patent number: 11163342
    Abstract: A chassis includes a housing of an expansion card receiver adapted to house an expansion card and limit removal of the expansion card to a removal path; and a card holder of the expansion card. The card holder, while a retention member of the card holder is disposed in the removal path, receives a translation force directed away from the expansion card along the removal path; in response to receiving the translation force: translates the retention member along the removal path away from the expansion card until the retention member reaches a translation limiter to transition the retention member from a translatable state to a rotatable state, while the retention member is in the rotatable state and not in the translatable state: receives a rotation force directed out of the removal path; and in response to receiving the rotation force, rotate the retention member out of the removal path.
