Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An apparatus comprising:
a light-diffusion box;
a chip tray positioned above the light-diffusion box, wherein an underside of the chip tray has a transparent portion for at least one column of the chip tray;
a range imaging device positioned at a top of the at least one column of the chip tray;
one or more image sensors positioned with a viewing perspective of the transparent portion of the underside of the chip tray; and
a tracking controller configured to perform operations that cause the apparatus to
illuminate the light-diffusion box with diffused light, wherein the diffused light shines through the transparent portion of the chip tray and illuminates the edge of one or more chips in a chip stack visible via the transparent portion;
capture, via the one or more image sensors in response to illumination of the light-diffusion box, an image of the edge of the one or more chips;
associate, in response to electronic analysis of the image via a neural network model, a color pattern on the edge of the one or more chips with a denomination value for the chip stack;
determine, using the range imaging device, a height of the chip stack; and
compute a monetary value of the chip stack based on the denomination value, the height of the chip stack, and a known edge thickness of one of the one or more chips.
