Abstract: A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.

Abstract: De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.

Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having a minor axis that moves relative to a main axis to define a spacing between the housing portions. A main bracket couples to the first housing portion and rotationally couples through first and second telescoping members with first and second secondary brackets disposed at opposing sides of the main bracket and coupled to the second housing portion. The telescoping members synchronize through a linkage of the main bracket to adjust the distance between the minor and main axes for 360 degrees of rotation and adapting to an object located between the housing portions when the housing portions close.

Abstract: A portable information handling system transforms between clamshell and all-in-one positions by sliding a display housing pivot axis towards a front side of a main housing and raising the rear side of the main housing with a stand that extends out from a bottom surface of the main housing. A keyboard detaches from the main housing upper surface to expose guides that manage the display housing sliding motion towards the main housing front side. The all-in-one position raises the main housing towards a near-vertical orientation to raise the display above a support surface for end user viewing while an end user interacts with the keyboard separated from the housing.

Abstract: An information handling system hinge provides friction against rotational motion to generate torque that regulates housing portion relative position. Friction is generated by compression of friction elements with a super elastic wire under tension. For example, a nickel titanium alloy wire under two to eight percent strain provides a relatively low spring rate having consistent compression even as wear reduces the size of the friction elements.

Abstract: A camera module includes a camera, a charging coil, and a magnetic assembly. The charging coil is located in a bottom portion of the camera module. The charging coil provides wireless charging of the camera. The magnetic assembly is located in a rear portion of the camera module. The magnetic polarities of the magnetic assembly produce a large magnetic flux outside the camera module and a low magnetic flux within the camera module.

Abstract: A portable information handling system keyboard includes plural keys that each have a programmable variable-feel response to an end user experience with key interactions in real time. In one example embodiment, a magnetic-rheological fluid is disposed in a chamber of the key to pass through openings formed in a piston that moves downward with a keypress and upward in response to a biasing mechanism, such as a spring disposed in the chamber. Current applied to a coil around the chamber creates a magnetic field that varies the viscosity of the fluid so that key compression and range of motion associated with an input as well as key movement to a raised position are programmable to adjust based upon a sensed key position and movement.

Abstract: A portable information handling system display has an OLED film disposed over front and rear faces of a substrate, such as a carbon fiber material. A protective cover is disposed over the OLED film with a folded portion along an end of the substrate, the protective cover hardened at the front and rear faces and left unhardened along the folded portion. In one example embodiment, a transparent bezel is placed over the folded portion with the OLED film presenting system information through the bezel, such as battery state, etc.

Abstract: A portable information handling system keyboard extends and retracts keys of a keyboard based upon one or more predetermined conditions, such as a power on command, a power off command and a rotational position of a housing lid and main portion. A nickel titanium alloy wire actuates retraction and/or extension of keyboard keys with application of a current to the wire.
