Abstract

A portable computing device including a housing having a top surface and a bottom surface connected to one another by a pair of sides, a proximal end and a distal end, the top surface including a user interface for operation by a user. The device comprises a planar surface located on the bottom surface at the proximal end, such that the planar surface extends to either side of a centerline of the housing and in a direction towards the distal end. The planar surface defines a plane and the centerline extends in a direction between the proximal end and the distal end. The device has at least one protrusion located on the bottom surface at the distal end, such that the at least one protrusion extends between the bottom surface and the plane, such that the at least one protrusion has a respective peripheral surface lying on the plane on both sides of the centerline. The at least one protrusion and the planar surface provide stability of the device when placed on a surface adjacent to the bottom surface, the stability facilitating operation of the user interface by the user.

Claims

1. A portable computing device including a housing having a top surface and a bottom surface connected to one another by a pair of sides, a proximal end and a distal end, the top surface including a user interface for operation by a user, the device comprising:

a planar surface located on the bottom surface at the proximal end, the planar surface extending to either side of a centerline of the housing and in a direction towards the distal end, the planar surface defining a plane, the centerline extending in a direction between the proximal end and the distal end;

a first protrusion located on the bottom surface at the distal end, the first protrusion extending between the bottom surface and the plane, such that the first protrusion has a peripheral surface lying on the plane on one side of the centerline;

a second protrusion located on the bottom surface at the distal end, the second protrusion extending between the bottom surface and the plane, such that the second protrusion has a peripheral surface lying on the plane on the other side of the centerline;

wherein the first protrusion, the second protrusion and the planar surface provide stability of the device when placed on a surface adjacent to the bottom surface, the stability facilitating operation of the user interface by the user, and

wherein the planar surface is provided as a raised rim around a periphery of at least a portion of a bottom surface of a power source cover, such that the rim has a peripheral surface that defines the plane that is in common with the peripheral surface of the first protrusion and the peripheral surface of the second protrusion.

2. The device of claim 1, wherein the peripheral surfaces of the first protrusion and the second protrusion are arcuate.
