Abstract: The system and method described below allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating control signals in the scheme.

Abstract: A self-destructing device includes a stressed substrate with a heater thermally coupled to the stressed substrate. The device includes a power source and trigger circuitry comprising a sensor and a switch. The sensor generates a trigger signal when exposed to a trigger stimulus. The switch couples the power source to the heater in response to the trigger signal When energized by the power source, the heater generates heat sufficient to initiate self-destruction of the stressed substrate.

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 microassembler system includes an alignment surface, a two-dimensional array of electrodes adjacent the alignment surface, a sensor network arranged adjacent the array of electrodes, and a control computer electrically connected to the array of electrodes and the sensor network, the control computer to receive signals from the sensor network indicating a position of at least one chiplet and to actuate the electrodes to change the position of the chiplet based upon the signals. A method of assembling chiplets includes receiving, at one of an array of control logic units, a signal from a control computer identifying an assembly location in a block of an assembly template at which a chiplet is to be located, using a sensor to determine a chiplet location of a nearest chiplet, and generating, using electrodes corresponding to the control logic unit, a traveling wave pattern to translate and orient the nearest chiplet to the location.

The ejector conduits are arranged in an array, each ejector conduit comprising: a first passageway fluidly connecting a first end of the ejector conduit to a conduit junction, the first end configured to accept a first print material; a second passageway fluidly connecting a second end of the ejector conduit to the conduit junction, the second end configured to accept a second print material; and a third passageway fluidly connecting a third end of the ejector conduit to the conduit junction. The third end comprises an ejector nozzle, the ejector nozzle comprising a first electrode and a second electrode, at least one surface of the first electrode being exposed in the third passageway and at least one surface of the second electrode being exposed in the third passageway. A current pulse generating system is in electrical connection with the first electrode and the second electrode of the plurality of ejector conduits. A magnetic field source is sufficiently proximate the second end of the plurality of ejector conduits so as to generate a flux region disposed within the ejector nozzle of the plurality of ejector conduits during operation of the 3D printer. The 3D printer further comprises a positioning system for controlling the relative position of the ejector device with respect to a print substrate in a manner that would allow the print substrate to receive print material jettable from the ejector nozzle of the plurality of ejector conduits during operation of the 3D printer.
