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 system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.

Abstract: A system and method for treatment of thread includes a thread printer that applies colored coatings to thread and that passes the treated thread to a fabric weaving system. A camera is positioned to capture images of the treated thread as it is woven into a fabric in the fabric weaving system. The system processes the images to determine whether the location of a selected segment of the treated thread in the fabric corresponds to an expected location in the fabric. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of a segments to automatically account for the misalignment.

Abstract: A transform memory controller and method are described herein wherein the transform memory controller comprises logic elements configured to perform desired transform operations on data that flows to-and-from conventional computer memory elements. The transform operations are configured to perform operations on such data without the need for such data to travel to-and-from the conventional computer memory element via the processor (e.g., Central Processing Unit (CPU)) of the computer system. Several desirable transform operations are herein disclosed.

Abstract: A 3D printing system includes an ejector configured to receive a build material. The ejector includes a nozzle. The ejector is configured to eject a plurality of drops of the build material through the nozzle. The 3D printing system also includes a substrate positioned below the nozzle. The drops fall toward the substrate after being ejected from the nozzle. The drops form a 3D object on the substrate. The 3D printing system also includes a power source configured to generate an alternating electrical current. The 3D printing system also includes an electrode configured to generate a plasma in response to receiving the alternating electrical current. The drops, the 3D object, the substrate, or a combination thereof are positioned at least partially within the plasma.

Abstract: Methods and systems to commission building environmental sensors are disclosed. The system includes a device that will move about the environment of a building (inside and/or outside) and detect building environmental sensor devices that are installed in the environment. For each of the sensor devices, in response to detecting the sensor device, the system will retrieve an identifier for the sensor device, and it will determine whether the sensor device is registered with a control system. If the sensor device is registered with the control system, the system will not automatically implement a commissioning process with the sensor device. If the sensor device is not registered with the control system, the system will automatically implement the commissioning process with the sensor device.
