  • Patent number: 12119573
    Abstract: An information handling system to wirelessly transmit and receive data at an antenna may include a processor; a memory; a power management unit; a display housing containing components of the information handling system, the display housing including metal sidewalls formed along edges of a back metal chassis of the display housing and generally perpendicular to the back metal chassis; an antenna formed into a first sidewall of the display housing and nested into the first sidewall with a molded plastic keep-out structure to, upon execution of the processor, create radiating radio frequency (RF) bands from the antenna; the antenna operatively coupled to a feed excitation trace to transmit an excitation current to the antenna from a wireless interface adapter; and the plastic molded keep-out structure integrated along the sidewall to secure the antenna to the first sidewall.

  • Publication number: 20200393874
    Abstract: A display stand cavity accepts an information handling system secured with a cover over the cavity held in place by a latch. The latch interacts with a locking element of the display stand to maintain the cover in position and slides to an unlocked position to release the cover for removal. An anchor engages with the latch to hold the latch in the unlocked position while the cover remains in place. The anchor releases the latch when the cover is removed from the display stand. If the cover remains in place, application of greater than a predetermined force on the latch towards the closed position overcomes the anchor to re-engage the latch to couple the cover to the display stand.

  • Patent number: 10310556
    Abstract: An information handling system rotationally couples first and second housing portions to each other with a dual axis hinge having proximately located dual axis assemblies with aligned parallel axes. A tensile member routed through each dual axis assembly and coupled to opposing front and rear faces motivate synchronized motion of the parallel dual axis assemblies without a geared mechanism. Torque regions defined by each dual axis assembly coordinate housing portion resistance to rotation at predetermined portions of the relative rotational movement.
