Abstract: In some examples, an apparatus can include a print substance gauge to indicate a quantity of print particles an imaging device is capable of receiving at a particular time, and an authentication mechanism coupled to a locking mechanism, the authentication mechanism includes instructions to: determine a quantity of print particles within a print particle container, and unlock the locking mechanism when the print substance gauge indicates that the imagining device is capable of receiving the quantity of print particles within the print particle container.

Abstract: Examples of creating moving light patterns in a light pipe having a plurality of Light Emitting Diodes (LEDs) are described. In an example, a plurality of keyframes is obtained. The plurality of keyframes define the moving light pattern. Each keyframe is indicative of red-greenblue (RGB) illumination values of each LED 5 from the plurality of LEDs. Further, a linear interpolation is performed, at run-time, between two keyframes of the plurality of keyframes to obtain a plurality of interpolated frames. Each interpolated frame is indicative of interpolated RGB illumination values of each LED. Based on the RGB illumination values of 10 the plurality of keyframes and interpolated RGB illumination values of the plurality of interpolated frames, the plurality of LEDs is illuminated, to create the moving light pattern.
