  • Patent number: 11892885
    Abstract: A portable information handling system glass ceramic housing has a cut out section at an opening and a speaker chamber cover disposed in the opening to integrate a speaker at a bottom front side of the housing. A speaker coil couples to the housing section to align with a speaker magnet coupled to the speaker chamber cover to generate audible sound in a speaker chamber defined when the housing section couples over the opening. A polymer material is disposed between the housing section and housing, and the housing section is cut out with an upward curve, so that audible sound is directed upwards from the housing and towards an end user of the information handling system.

  • Patent number: 11797052
    Abstract: An information handling system display with zero bezel defines a perimeter with a square side of a cover glass having a curved interior surface and a gradient refractive index portion that focuses visual images from a folded display film to a flat upper surface of the cover glass. The folded display film provides a display image across a full length of the cover glass while fitting under the cover glass with the fold and presenting undistorted visual images through the lens focus provided by the gradient refractive index portion.

  • Patent number: 11656659
    Abstract: A portable information handling system housing rotationally couples housing portions with a dual axis synchronized gear to rotate about parallel spaced axes that define a radius to support folding of a flexible display. Each axis of the synchronized gear couples to a housing portion with a sliding bracket that adjusts length during rotation. Plural pivot arms couple to a main body of the hinge at the first and second axes and to the housing portions to manage spacing of the housing portions during rotation. A sliding member coupled to the main body engages with the plural pivot arms to synchronize rotation of the plural pivot arms and regulate torsional forces related to rotation of the housing portions that can damage a display film folding at the hinge.

  • Publication number: 20230126612
    Abstract: A haptic touchpad may include a seamless layer of glass; a touchpad assembly, including: a capacitive touch printed circuit board (PCB) operatively coupled to a bottom side of the seamless layer of glass via a first adhesive; a contact foil operatively coupled to the bottom surface of the capacitive touch PCB via a second adhesive; a piezoelectric element array operatively coupled to a bottom side of the contact foil to receive an applied mechanical stress; and a controller of the information handling system operatively coupled to the piezoelectric element array to: receive electric actuation signals from the piezoelectric element array placed under the mechanical stress via the contact foil; and send an electrical response signal to the piezoelectric element array to cause the piezoelectric element array to generate haptic feedback; and a unibody C-cover support frame to support the touchpad assembly and the seamless layer of glass.

  • Patent number: 11609641
    Abstract: A multi-state keyboard function row is provided. A plurality of representations can be formed on an insert of the multi-state keyboard function row. An assembly of the multi-state keyboard function row can be configured to cause either a first set of the representations or a second set of the representations to be visible to a user. A brightness of the representations may also be controlled based on a brightness of ambient light.

  • Patent number: 11586261
    Abstract: A portable information handling system glass ceramic housing integrates a heat sink of thermally conductive wire disposed in a coil or mesh pattern that is difficult to discern from the housing exterior. A thermal transfer device communicates thermal energy from internal processing components to the heat sink in aesthetically pleasing manner. For example, a plastic logo is coated with graphene to transfer thermal energy by pressing against the thermally conductive wire so that that logo is visible from the housing exterior. Through glass via opening provide air passages between the housing interior and exterior to promote rejection of the thermal energy from the housing.

  • Publication number: 20230018781
    Abstract: A portable information handling system or docking station glass ceramic housing integrates antenna conductive wires in a first glass ceramic piece and a director conductive wire in a second glass ceramic piece coupled to the first ceramic glass piece, such as with optically-clear adhesive. A conductive contact interfaces the antenna conductive wire by exposure at the glass ceramic housing interior where pogo pins of a printed circuit board assembly bias against the conductive contacts to communicate the radio signals. The director conductive wire provides a parasitic element for directional control of the wireless signal. Ground conductive wires may integrate in the exterior side of the second glass ceramic piece and interface with the radio to provide a dipole antenna.

  • Publication number: 20230015184
    Abstract: A portable information handling system glass ceramic housing integrates plural wires on opposing sides that interface with a radio to provide a dipole antenna, such as with a radio conductor output interfaced at a wire of the interior side and a radio ground output interfaced at a wire of the exterior side. Conductive contacts interface with the wires by exposure at the glass ceramic housing interior where pogo pins of a printed circuit board assembly bias against the conductive contacts to communicate the radio signals. In one example embodiment, the conductive contacts co-locate with a logo etched into the glass ceramic housing to provide an aesthetically pleasing antenna interface that is difficult to visually detect at the glass ceramic housing exterior.

  • Publication number: 20230012464
    Abstract: A portable information handling system glass ceramic housing integrates plural wireless charging coils on one side and plural coil interface traces on an opposing side that interface with conductive material disposed in through glass via openings. Conductive contacts interfaced with the coil interface traces and exposed at the glass ceramic housing interior couple to a printed circuit board assembly through pogo pins that bias against the conductive contacts to communicate power from the wireless charging coils to the charger of the information handling system. The conductive contacts co-locate with a logo etched into the glass ceramic housing to provide an aesthetically pleasing wireless charging solution.

  • Patent number: 11480995
    Abstract: An all-in-one information handling system holds a display in a raised forward position with a support arm rotationally coupled at a rear side of the information handling system housing and a central location of the display. Gear arms integrated in the support arm engage a gear at the display and gear mechanism at the housing to synchronize rotation of the display from the forward and raised vertical position relative to the housing to a central and lower horizontal position by lowering the support arm to a horizontal position supported by the housing upper surface as the display rotates to the horizontal position.
