Abstract: A label comprising multiple layers. In one aspect, the label includes an ablation layer and a print layer configured to be below the ablation layer. The ablation layer may have a first color and can comprise at least one infrared (IR) absorbing material and at least one visible light reflecting material. The print layer may have a second color and can comprise at least one IR reflecting and visible light absorbing material. The second color is darker than the first color. The unique chemical composition of the label allows for an ablative substrate with a white top layer and a black bottom layer that results in a strong contrast. In some forms, an adhesive layer in a label might serve as both the print layer and an adhesive layer. In some forms the label can be cut to size with the same laser that engraves print and graphics.

Abstract: In one mode of an interface, a bounded area is displayed on a mobile device. A straight line is displayed that divides the bounded area into first and second areas. An angle of the line indicates an orientation of a first axis of the mobile device relative to a respective vector. In response to detecting the change in orientation of the second axis of the device relative to the vector, while maintaining the angle of the line at a first angle, a relative size of the first and second areas is changed in accordance with the change in orientation of the second axis. In a second mode, first and second bounded shapes are displayed. Positions of the bounded shapes with respect to each other are changed along one or more axes in response to a change in orientation of a surface of the mobile device relative to a respective vector.
