Abstract: Systems and methods for printing a three-dimensional object containing information embedded as three-dimensional physical representations are disclosed. The methods include receiving information to be embedded in the three-dimensional object, determining a mapping between the received information and a plurality of three-dimensional physical representations to be embedded in the three-dimensional object, generating a build sequence that will cause the three-dimensional printing device to print the three-dimensional object comprising the plurality of three-dimensional physical representations in accordance with the mapping. The three-dimensional printing device uses the build sequence to print the three-dimensional object comprising the plurality of three-dimensional physical representations.

Abstract: A three-dimensional barcode comprising a three-dimensional barcode structure, at least a part of which is printed on a surface of an object. The barcode structure includes encoded information, and at least part of the encoded information is embedded in a z-dimension perpendicular to the surface of the object.

Abstract: A system that includes a three-dimensional (3D) printing device, processor and computer-readable memory a 3D barcode and prints a three-dimensional object containing information embedded in the 3D barcode by: (i) receiving information to be embedded in the 3D barcode; (ii) determining a barcode symbology, wherein the barcode symbology includes at least one symbol character in a z-dimension; (iii) generating a build sequence that will cause the 3D-printing device to print the 3D barcode that embeds the received information in the 3D barcode in accordance with the barcode symbology; and (iv) using the build sequence to print the 3D object so that each symbol character of the symbology that is to appear in the z-dimension is printed as a physical representation in the z-direction on the 3D object.

Abstract: A method for detecting a stress condition in a cleaning system of an imaging device is provided. The method comprises receiving a pulse-width modulated (PWM) signal. The PWM signal has a duty cycle for driving a PWM servo motor of a cleaning system. A determination is then made whether the duty cycle of the PWM signal indicates that the servo motor is working within design limits. If the duty cycle is within design limits, characteristic adjustments of the duty cycle of the PWM are detected that indicate an occurrence of a non-catastrophic stress condition in the cleaning system. Once a characteristic adjustment of the duty cycle is detected, an alert signal is generated.
