Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having first and second breakaway brackets that define an adjacent position of the first and second housing portions relative to each other and a spread position. The first and second breakaway brackets expand the spacing between the first and second housing portions in the event that the housing portions close over an object disposed between them. The breakaway brackets bias to the adjacent position with a biasing device and a retainer that maintains the adjacent position unless a predetermined force is applied through the hinge assembly at the breakaway brackets.

Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having first and second axles held in a parallel fixed lateral disposition by interaction of first and second chassis that slide to move the axles to varied distances. The first and second axles transfer rotation through one or more belts and first and second transfer pulleys rotationally coupled with members that adjust transfer pulley positions as the distance between the first and second axles change to maintain belt tension.

Abstract: A haptic keyboard of an information handling system may comprise a coversheet to identify a key location, a support layer, a contact foil placed between the coversheet and support layer, and a controller operatively coupled to the contact foil. The controller may receive a haptic actuation indicator signal via a processor or via the contact foil, send a first haptic feedback control signal to a first piezoelectric element to cause the first piezoelectric element to generate haptic tactile movement feedback at the key location, and send a second haptic feedback control signal to the first or a second piezoelectric element to cause the second piezoelectric element to generate haptic sound feedback in response to the haptic actuation indicator signal.

Abstract: A haptic keyboard based sound system of an information handling system comprising a coversheet to identify a plurality of key locations of a haptic keyboard and a first key having a piezoelectric element for haptic tactile feedback upon key actuation, a support layer, a contact foil placed between the coversheet and support layer, and a haptic feedback and piezo sound controller operatively coupled to the contact foil to receive the mid-frequency portion of an audio signal and the high frequency portion of the audio signal from an audio controller operably connected to the haptic feedback and piezo sound controller, and send a piezo audio signal to the piezoelectric element to cause the piezoelectric element to generate a mid-frequency and high-frequency sound audio according to the received mid-frequency portion of an audio signal and the high frequency portion of the audio signal.

Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having first and second axles held in a parallel fixed lateral disposition and selectively engaging with a first or second gear assembly having a first or second gear ratio. A distance between the first and second axles varies based upon the selected gear assembly to adapt the information handling system to accept a keyboard between the first and second housings.

Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly having first and second axles held in a parallel fixed lateral disposition by interaction of a gear chassis, a drive carriage and an idler assembly. The first and second axles expand to increase the distance between the first and second housing portions in the event that the housing portions close over an object disposed between them. The idler assembly couples to the gear chassis and drive carriage to rotate with the second axle as it moves relative to the first axle.

Abstract: A portable information handling system housing rotationally couples first and second housing portions with a hinge assembly that provides a variable distance between the housing portions, such as with first and second axles move together and apart or with a main bracket having telescoping members on opposing sides that provide rotation about a minor axis. Increased distance between the housing portions may accommodate a keyboard disposed between the housing portions or provide extra space if an object is placed between the housing portions so that a display integrated in the housing is not damaged.
