The need to include a half-pipe section on the upper surface of the lower body maybe avoided. Thus more internal space of the lower body may be used without having to accommodate for the hinge. In an exemplary embodiment, the hinge may include a cam surface. The cam surface may be configured to shift a longitudinal axis of the hinge on response to the rotation of the upper body. In some embodiments, the shift of the longitudinal axis may be away from the lower body allowing a rear edge of the upper body to move across a rear edge of an upper surface of the lower body. ## Claims ### Claim 1 A device, comprising: a first device body; a second device body; a hinge comprising a hinge body configured to rotate about a longitudinal axis of the hinge, wherein the hinge connects the first device body to the second device body, and wherein the hinge is configured to move the second device body relative to the first device body in response to rotation of the second device body about the hinge; a connection portion in the first device body connecting the hinge to the first device body, the connection portion including a flat upper surface of the connection portion; a cam within the hinge, the cam configured to shift the longitudinal axis of the hinge in response to movement of the hinge body, wherein the flat upper surface of the connection portion is disposed to oppose contact by the cam during rotation of the hinge, wherein rotation of the second device body relative to the first device body drives the hinge body away from the flat upper surface of the connection portion increasing a distance between the longitudinal axis of the hinge and the flat upper surface of the connection portion, while the flat upper surface of the connection portion remains in place relative to the first device body. ### Claim 2 (depends on 1) The device of claim 1, wherein the hinge body is a barrel. ### Claim 3 (depends on 1) The device of claim 1, wherein the cam includes an oval exterior surface. ### Claim 4 (depends on 1) The device of claim 1, wherein the first device body is a lower body of an electronic device and comprises a keyboard, and wherein the second device body is an upper body of the electronic device and comprises a display. ### Claim 5 (depends on 1) The device of claim 1, wherein the cam is an eccentric type cam. ### Claim 6 A portable electronic device, comprising: an upper device body; a lower device body; a flat upper surface in the lower device body; a hinge connecting the upper device body to the lower device body, the hinge configured to move the upper device body relative to the lower device body in response to rotation of the upper device body about a longitudinal axis of the hinge; a connection portion in the lower device body connecting the hinge to the lower device body, the connection portion including a flat upper surface of the connection portion; and a cam within the hinge, wherein the flat upper surface in the lower device body is disposed to opposed contact by the cam during rotation of the hinge and to shift the longitudinal axis of the hinge away from the lower device body in response to movement of the upper device body relative to the lower device body, increasing a distance between the longitudinal axis of the hinge and the flat upper surface, providing clearance for the rotation of the upper device body, and wherein the lower device body includes an input device. ### Claim 7 (depends on 6) The portable electronic device of claim 6, further comprising a connection portion in the lower device body connecting the hinge to the lower device body, the connection portion including the flat upper surface, wherein the flat upper surface is disposed to oppose contact by a surface of the cam during rotation of the hinge, wherein rotation of the hinge raises the longitudinal axis of the hinge with respect to the lower device body. ### Claim 8 (depends on 6) The portable electronic device of claim 6, wherein the upper device body includes a display. ### Claim 9 (depends on 8) The portable electronic device of claim 8, wherein the lower device body includes a keyboard. ### Claim 10 (depends on 6) The portable electronic device of claim 6, wherein the hinge is a barrel-type hinge. ### Claim 11 (depends on 6) The portable electronic device of claim 6, wherein the rotation of the upper device body comprises opening the upper device body from a closed position with the lower device body. ### Claim 12 A computing system, comprising: an upper device body comprising a cover, the cover including a rear edge of the cover; a lower device body; a hinge connecting the upper device body to the lower device body; a connection portion in the lower device body connecting the hinge to the lower device body, the connection portion including a flat upper surface of the connection portion; and a cam surface of the hinge disposed to contact the flat upper surface portion of the lower device body in response to rotation of the cover about a longitudinal axis of the hinge from a closed position to an open position, wherein a the longitudinal axis of the hinge is raised relative to the lower device body, thereby increasing a distance between the longitudinal axis and the flat upper surface portion in response to rotation of the cover to the open position, while the flat upper surface portion of the lower device body contacted by the cam surface of the hinge remains in place with respect to the lower device body. ### Claim 13 (depends on 12) The computing system of claim 12, wherein the lower device body includes an input device. ### Claim 14 (depends on 13) The computing system of claim 13, further comprising a spring coupled to the upper device body. ### Claim 15 (depends on 14) The computing system of claim 14, wherein the spring is configured to provide a counter force to the cam surface in response to rotation of the cover from the first position into the second position. ### Claim 16 (depends on 15) The computing system of claim 15, wherein the spring is configured to shift the longitudinal axis of the hinge from the open position to the closed position in response to rotation of the cover from the open position to a the closed position. ### Claim 17 (depends on 12) The computing system of claim 12, wherein the rear edge of cover is disposed to move across a rear edge of an upper surface of the lower device body in response to the rotation of the cover from the first position into the second position. ### Claim 18 (depends on 12) The computing system of claim 12, wherein the lower device body includes a keyboard. ### Claim 19 (depends on 18) The computing system of claim 18, wherein the upper device body includes a display.
