Abstract: A 3D printer includes an ejector device comprising a substrate and a plurality of ejector conduits on the substrate, the ejector conduits being arranged in an array. Each ejector conduit includes: a first end positioned to accept a print material, a second end comprising an ejector nozzle, the ejector nozzle comprising a first electrode and a second electrode, and a passageway for allowing the print material to flow from the first end to the second end, at least one surface of the first electrode being exposed in the passageway and at least one surface of the second electrode being exposed in the 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.

Abstract: System and method that allow utilize machine learning algorithms to move a micro-object to a desired position are described. A sensor such as a high speed camera or capacitive sensing, tracks the locations of the objects. A dynamic potential energy landscape for manipulating objects is generated by controlling each of the electrodes in an array of electrodes. One or more computing devices are used to: estimate an initial position of a micro-object using the sensor; generate a continuous representation of a dynamic model for movement of the micro-object due to electrode potentials generated by at least some of the electrodes and use automatic differentiation and Gauss quadrature rules on the dynamic model to derive optimum potentials to be generated by the electrodes to move the micro-object to the desired position; and map the calculated optimized electrode potentials to the array to activate the electrodes.

Abstract: A method of manufacturing an intermediate transfer surface includes depositing an array of etch stops on a conductive surface, etching the conductive surface to form mesas of the conductive surface separated by gaps, and coating the mesas with a dielectric coating. A method of performing microassembly includes forming an assembly of particles on an assembly plane, providing an intermediate transfer surface having an array of electrodes, applying a bias to the intermediate transfer surface to form an electrostatic field between the assembly plane and the intermediate transfer surface, and moving the intermediate transfer surface towards the assembly surface until the electrostatic field strength is strong enough to cause transfer of the assembly to the intermediate transfer surface.

Abstract: An embodiment is a method and apparatus for coherent ultrasonic imaging. A receiver array has a plurality of receiver elements on a substrate to detect in-phase and quadrature components of a received signal corresponding to a transmit signal. Each of the receiver elements includes a receiver transducer and a thin-film transistor (TFT) receiver circuit. The TFT receiver circuit includes a quadrature detector having a mixer to mix a received signal with a reference signal in a composite bias signal that is distributed across the plurality of receiver elements. A transmitter is acoustically coupled to the plurality of receiver elements to generate the transmit signal through an imaging medium.

Abstract: The system and method described 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 voltage patterns 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.
