A system includes a wafer including at least an electronic component and a probe pad including a built-in back-end-of-line (BEOL) interconnect structure to test the electronic component. The electronic component is tested by the probe pad without building full BEOL interconnect circuits on the wafer. The probe pad is aligned with the wafer by using alignment marks. A prober alignment camera is employed to locate the alignment marks.

A system for servicing a data center using an autonomous vehicle (AV) is provided. The system comprises the AV and the AV is configured to: receive a task to perform within the data center, wherein the data center comprises a plurality of servers associated with a plurality of enterprise organizations; navigate from an initial location within the data center to a new location within the data center along a path extending through a portion of the data center, the path being determined automatically; and while navigating the path and in response to encountering a movable barrier disposed along the path, performing a procedure to bypass the movable barrier such that the AV can continue navigating along the path.

Methods, electrodes, and electrochemical devices using surface-modified pseudo-graphite are disclosed. In one illustrative embodiment, a method may include depositing a pseudo-graphite material onto a surface of an electrode substrate to produce a pseudo-graphite material surface. The method may also include modifying the pseudo-graphite material surface to alter electrochemical characteristics of the electrode.

A technique relates to an integrated circuit (IC). Pillars of a set of memory elements are formed. A bilayer dielectric is formed between the pillars, the bilayer dielectric having an upper dielectric material formed on a lower dielectric material without requiring an etch of the lower dielectric material prior to forming the upper dielectric material, thereby preventing a void in the bilayer dielectric, the lower dielectric material including one or more flowable dielectric materials.

Embedding MRAM device in advanced interconnects

A system and method that automatically resolves conflicts among sensor information in a sensor fusion robot system. Such methods can accommodate converging ambiguous and divergent sensor information in a manner that can allow continued, and relatively accurate, robotic operations. The processes can include handling sensor conflict via sensor prioritization, including, but not limited, prioritization based on the particular stage or segment of the assembly operation when the conflict occurs, overriding sensor data that exceeds a threshold value, and/or prioritization based on evaluations of recent sensor performance, predictions, system configuration, and/or historical information. The processes can include responding to sensor conflicts through comparisons of the accuracy of workpiece location predictions from different sensors during different assembly stages in connection with arriving at a determination of which sensor(s) is providing accurate and reliable predictions.

A submersible remotely operable vehicle used for inspection of liquid cooled electrical transformers can include a number of separate cameras and sensors for mapping and navigating the internal structure of the transformer with liquid coolant remaining in the transformer. The remotely operable vehicle can be wirelessly controlled to perform various inspection functions while the number of cameras provide video streams for processing to produce a three dimensional field of view based on an observation position of the remotely operable vehicle.

A robotic system is provided for assembling parts together. In the assembly process, both parts are moving separately with one part moving on an assembly base and another part moving on a moveable arm of a robot base. Motion data is measured by an inertial measurement unit (IMU) sensor. Movement of the robot base or moveable arm is then compensated based on the measured motion to align the first and second parts with each other and assemble the parts together.

A submersible vehicle which includes a plurality of cameras can be used to collect visual images of an object of interest submerged in a liquid environment, such as in a tank (e.g. transformer tank). In one form the submersible vehicle is remotely operated such as an ROV or an autonomous vehicle. Image information from the submersible along with inertial measurements in some embodiments is used with a vision based modelling system to form a model of an internal object of interest in the tank. The vision based modelling system can include a number of processes to form the model such as but not limited to tracking, sparse and dense reconstruction, model generation, and rectification.

A system and method for predicting the location at which a feature that is being tracked during a robotic assembly operation will be located within one or more images captured by a vision device. A vision device can be mounted to a robot such that the location of the vision device as the robot moves can be known or determined. In the event of an interruption of the tracking of the feature by the vision device as the corresponding workpiece is moving, the location of the feature relative to a vision device can be predicted, such as, via use of current or past historical movement information for the feature and/or the associated workpiece. Using the predicted location of the feature and the known location of the vision device, the location at which the feature will be located in an image(s) captured by the vision device can be predicted.

By forming the second bottom interconnect after the device fabrication and capping, damage to the device and to the second bottom interconnect is avoided.
