Dual screen electronic devices with stowable keyboards

Abstract

Apparatus, systems, articles of manufacture, and methods have been disclosed that include example hinges to couple a first screen and a second screen of an electronic device. An example apparatus includes a first gear rotatable about a first axis of rotation, a second gear rotatable about a second axis of rotation, and a link gear rotatably coupled to the first gear and rotatably coupled to the second gear.

1 . (canceled) 
     
     
         2 . An electronic device comprising:
 a first display;   a second display;   a hinge rotatably coupling the first display and the second display;   a physical keyboard removably positionable on the second display;   instructions; and   processor circuitry to execute the instructions to:
 present a first user interface on the second display when the physical keyboard is not positioned on the second display, 
 present a second user interface on a first portion the second display when the physical keyboard is positioned on a second portion of the second display, and 
 present a third user interface on the second portion of the second display when the physical keyboard is positioned on the first portion of the second display. 
   
     
     
         3 . The electronic device of  claim 2 , further including:
 a first magnetic element associated with the second display; and   a second magnetic element associated with the keyboard, the keyboard magnetically couplable to the second display.   
     
     
         4 . The electronic device of  claim 2 , wherein the keyboard is in wireless communication with the processor circuitry. 
     
     
         5 . The electronic device of  claim 4 , wherein the keyboard and the processor circuitry are to communicate via a Bluetooth protocfol. 
     
     
         6 . The electronic device of  claim 2 , wherein the hinge creates a gap between the first display and the second display. 
     
     
         7 . The electronic device of  claim 2 , wherein the first portion of the second display is closer to the hinge than the second portion of the second display, and the third interface is a virtual trackpad. 
     
     
         8 . The electronic device of  claim 2 , wherein the first portion of the second display is closer to the hinge than the second portion of the second display, and the second interface includes a plurality of emojis. 
     
     
         9 . An electronic device comprising:
 a first display;   a second display;   means for rotatably coupling the first display and the second display;   a physical keyboard removably positionable on the second display; and   means for processing instructions, the processing means to:
 present a first user interface on the second display when the physical keyboard is not positioned on the second display, 
 present a second user interface on a first portion of the second display when the physical keyboard is positioned on a second portion of the second display, and 
 present a third user interface on the second portion of the second display when the physical keyboard is positioned on the first portion of the second display. 
   
     
     
         10 . The electronic device of  claim 9 , further including means for magnetically coupling the keyboard to the second display. 
     
     
         11 . The electronic device of  claim 9 , further including means for communicatively coupling the keyboard with the processing means. 
     
     
         12 . The electronic device of  claim 9 , wherein the means for rotatably coupling creates a gap between the first display and the second display. 
     
     
         13 . The electronic device of  claim 9 , wherein the first portion of the second display is closer to the rotatably coupling means than the second portion of the second display, and the third interface is a virtual trackpad. 
     
     
         14 . The electronic device of  claim 9 , wherein the first portion of the second display is closer to the rotatably coupling means than the second portion of the second display, and the second interface includes a plurality of emojis. 
     
     
         15 . At least one non-transitory computer readable medium comprising instructions that, when executed, cause an electronic device having a first display and a second display rotatably coupled to the first display via a hinge to at least:
 detect at least one of a presence or absence of a physical keyboard on one or more of the first display or second display;   present a first user interface on the second display when the physical keyboard is not positioned on the second display;   present a second user interface on a first portion the second display when the physical keyboard is positioned on a second portion of the second display, and   present a third user interface on the second portion of the second display when the physical keyboard is positioned on the first portion of the second display.
