Abstract

A transferable hybrid method for prognostics of engineering systems based on fundamental degradation modes is provided. The method includes developing a degradation model that represents degradation modes shared in different domains of application through the integration of physics and machine learning. The system measures sensor signals and data processing provides for extracting health indicators correlated with the fundamental degradation modes from sensors data. For the integration of physics and machine learning, the degradation mode is separated into different phases. Before the accelerated degradation phase of a system, the method is looking out to detect when the accelerated phase begins. When accelerated phase is active, the system applies a machine-learning model to provide information on the accelerated degradation phase, and evolves the degradation towards a failure threshold in a simulation of the updated physics-based model to predict the degradation progression. The system estimates the remaining useful life of the target system.

Abstract

System and method that allow to control density distributions of multiple particles (micro-or-nano-sized objects) to desired positions are described. A kernel density estimation (KDE) is used as a proxy for the initial particle density distribution and an optimal control problem is defined and solved using this approximation. A sequence of electrode electric potentials is computed so that the initial particle distribution is shaped into a target distribution after applying this sequence over time. The optimal control cost function is defined in terms of an L2 metric, with the L2 function that is used to compute the error between the particle density at the end of a time horizon and a target density. The KDE depends on the predicted trajectories of a set of particles, where the trajectory of a single particle is determined by a lumped, 2D, capacitive-based, nonlinear model describing the particle's motion.

Abstract

A system and method are provided wherein encrypted data is stored in modular lockers on a first storage volume associated with a high-power microprocessor deployed in a system. Each encrypted locker maps, for example, to a specific time segment (e.g., one day) which simplifies mounting of the encrypted volume for data access and reduces the locker size for external access of data while encrypted (e.g., via Wifi). New data in a second storage volume associated with and generated by a low-power microprocessor associated with the system gets transferred to the encrypted data store during wake cycles of the high-power microprocessor. To manage space on the first storage volume, time stamps associated with each encrypted locker allows simple removal of files older than a specified time period by removing of any encrypted lockers older than that threshold.

Abstract

A system and method provide a combination of a modular message structure, a priority-based message packing scheme, and a data packet queue management system to optimize the information content of a transmitted message in, for example, the Ocean of Things (OoT) environment. The modular message structure starts with a header that provides critical information and reference points for time and location. The rest of the message is composed of modular data packets, each of which has a data ID section that the message decoder uses for reference when reconstructing the message contents, an optional size section that specifies the length of the following data section if it can contain data of variable length, and a data section that can be compressed in a manner unique to that data type. The message packing scheme uses a combination of priority level and minimum reporting interval, both of which are dynamically configurable for each data packet type, to maximize the value of the information contained in the modular data packets included in each message. Finally, the data packet queues manage temporary storage of data packets that have been generated but not yet included in an outgoing message.

Abstract

A transfer apparatus includes a transfer layer formed of a thermally switchable material that undergoes a phase change when heated. A first side of the transfer layer is placed in contact with a chiplet during a transfer operation. An optical absorber material is thermally coupled the transfer layer. An optical energy source is operable to apply optical energy to the optical absorber material to selectively heat a region of the transfer layer that corresponds to a location of the chiplet. The region holds the chiplet when the optical energy is removed during the transfer operation. The region is subsequently heated during the transfer operation to release the chiplet. The transfer layer can be reused for repeated transfer operations.

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.

A processing device may compute a simulated manufactured geometry (e.g., a realistic representation of the actual shape of the corresponding physical object to be produced) based on the tool path and the one or more manufacturing parameters. The processing device analyzes the simulated manufactured geometry for a portion of removable AM materials trapped inside the simulated manufactured geometry. The processing device then generates a report regarding the portion of the removable AM materials trapped inside the simulated manufactured geometry.

Abstract

A 3D printing system and methods to selectively pattern dense feedstock based on selective inhibition sintering (SIS). A sintering selectivity agent (inhibitor or promoter) is selectively deposited on a build layer according to the pattern boundary. When the layers are built-up and the part is sintered, the inhibited region remains unbound, thus defining the edge of the part. The material contain powder embedded in cohesive binder that make the adjacent layer adhere together. The build process involves forming the sheets of dense feedstock embedded binder, followed by depositing ink to promote selective sintering onto the layer. Once the build is complete, the process continues with the binder removal, sintering and finishing processes.

Abstract

A differentiable physics model of a building is used that defines thermodynamic relationships between zones of the building and a heating, ventilation, and air-conditioning (HVAC) system. A physics-constrained, data driven model learns behaviors of controlled components of the HVAC system. For each of a series of times during online operation of the HVAC system, past state values are recorded representing a performance of the HVAC system in the building and past inputs to the HVAC system to maintain the states. The past state values and the past inputs are input into the differentiable physics model and the data driven model to: jointly update first parameters of the differentiable physics model and second parameters of the data driven model, e.g., using moving horizon estimation; and determine a current input to the controlled components, e.g., using model predictive control.

Abstract

One embodiment provides a method and a system for computing diagnoses for a physical system. During operation, the system can obtain a design of the physical system, generate a design of a diagnostic system by augmenting the design of the physical system based on a number of fault-emulating subsystems, and convert the design of the diagnostic system into a polynomial formula comprising a plurality of variables. The plurality of variables can include inputs and outputs of the original physical system and a number of ancillary variables. The system can further embed the polynomial formula on a hardware-based solver configured to perform optimization using the polynomial formula as an objective function to obtain a diagnostic vector used for explaining faults in the physical system.

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 method of operating an inkjet printer identifies a thermal load that will be imposed on the printheads in the inkjet printer during execution of a print job and identifies a remedial action to reduce the thermal load if the thermal load increases the temperature of the printheads above an upper threshold of a predetermined temperature range. The thermal load is identified from the ink image content data for the print job, the print job parameters for the print job, and environmental condition measurements received from sensors in the printer. The remedial actions include manipulation of the print job queue, alteration of print job parameters, and active cooling to remove heat from the printheads or media within the printer.

Abstract

Techniques for determining print quality for a 3D printer are disclosed. An example method includes obtaining an image of a stream of material jetted from a nozzle of the 3D printer, and binarizing the image to distinguish background features from foreground features contained in the image. The method also includes identifying elements of jetted material in the foreground features, and computing statistical data characterizing the identified elements. The method also includes generating a quality score of jetting quality based on the statistical data and controlling the 3D printer based on the quality score. The quality score indicates a degree to which the elements of jetted material form droplets of a same size, shape, alignment, and jetting frequency.
