Abstract: A printing system comprises an ink deposition assembly and a media transport device. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper. The media transport device holds the print media against a movable support surface, such as a belt, by vacuum suction platen and transports the print media though a deposition region. The vacuum suction is communicated to the movable through platen holes and platen channels in a vacuum platen. At least some of the platen channels have a high impedance region that has a reduced open cross-sectional area as compared to another region of the platen channel.

Abstract: A metal object manufacturing apparatus is configured to eject melted metal drops to form a continuous metal line over a line of spatially separated pillars in a single pass. The ejection frequency for forming the continuous metal line is different than the frequency used to form the pillars. In one embodiment, the ejection frequency for forming the pillars is about 100 Hz and the frequency used to form the continuous metal line over the line of spatially separated pillars is about 300 Hz with a drop spacing of about 0.2 mm. Continuous metal lines are formed to extend the continuous metal lines over the pillars laterally to fill the gaps between the continuous metal lines over the pillars. These continuous metal lines that fill the gaps are formed while operating the ejection head at the 300 Hz frequency with a drop spacing of 0.28 mm.

Abstract: Control loop latency can be accounted for in predicting positions of micro-objects being moved by using a hybrid model that includes both at least one physics-based model and machine-learning models. The models are combined using gradient boosting, with a model created during at least one of the stages being fitted based on residuals calculated during a previous stage based on comparison to training data. The loss function for each stage is selected based on the model being created. The hybrid model is evaluated with data extrapolated and interpolated from the training data to prevent overfitting and ensure the hybrid model has sufficient predictive ability. By including both physics-based and machine-learning models, the hybrid model can account for both deterministic and stochastic components involved in the movement of the micro-objects, thus increasing the accuracy and throughput of the micro-assembly.

Abstract: A feedback-based system and method that identifies characteristics of one or more cells and utilizes the characteristics to initiate and adjust a field applied to the one or more cells to control the cells' functioning and motility is provided. Machine learning can be leveraged to automatically identify characteristics of the one or more cells and adjust the parameters of the field based on the characteristics. Sensors are utilized during the application of the field to monitor characteristics of the one or more cells and parameters of the field. Specifically, characteristics of at least some of the cells are measured at different points, and the measurements are used to determine whether the desired effect has been achieved or whether unintended consequences are taking place. Based on the measurements, parameters of the field can be adjusted to achieve the desired effect on cell functioning, cell motility, or both.

Abstract: A feedback system that identifies characteristics of one or more cells being grown on a metasurface and utilizes the characteristics to initiate and adjust a field applied to the metasurface to control adhesion of the cells to and from the metasurface. The metasurface includes a plurality of structures whose resonances (localized or non-localized) have a wavelength range of 250 nm-3 microns. In one embodiment, the system leverages machine learning to automatically identify characteristics of the one or more cells or the metasurface and adjust the parameters of the field based on the characteristics. Sensors are utilized during the application of the field to monitor characteristics of the one or more cells or the metasurface and parameters of the field. Based on the measurements, parameters of the field can be adjusted to achieve the desired effect on the detachment of the cells.

Abstract: A feedback system that identifies characteristics of a colloid and utilizes the characteristics to initiate and adjust a field applied to the colloid is provided. In one embodiment, the system leverages machine learning to automatically identify a condition of the colloid and adjust the supercooling parameters. Sensors are utilized during supercooling to monitor a condition of the colloid being supercooled. Specifically, characteristics of the colloid are measured at different points, areas, or volumes on the colloid and the measurements are used to determine whether supercooling is being achieved or whether the colloid is starting to freeze or undergoing another undesirable phase change. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the colloid without freezing or causing another undesirable phase change. When phase change is desired, rate of phase change can be controlled to achieve desired characteristics of the colloid.

Abstract: A transfer member for a printing device includes a shaft, a rigid cylindrical core member, mounted on the shaft, an outer layer supported on the rigid cylindrical core member, and optionally a conformable intermediate layer, spacing the cylindrical core member from the outer layer. The outer layer defines an outer surface of the transfer member, and is configured for receiving a toner image thereon. The cylindrical core and outer layer have a same axis of rotation as the shaft. The rigid cylindrical core and/or the conformable intermediate layer, where present may be electrically biased, relative to a photoconductor drum of the printing device.

Abstract: An aqueous inkjet printer also ejects drops of UV material on an aqueous ink image and exposes the aqueous ink image and the UV material to UV radiation before passing the aqueous ink image and UV material through a thermal dryer. The exposure to UV radiation pins the UV material to the aqueous ink image and underlying substrate and the thermal dryer fixes the aqueous ink image to the substrate while releasing free radicals from the UV material. Thus, the printer produces textured prints that do not have free radicals that can irritate skin or produce noxious odors.
