Abstract: An item generation interface may generate knowledge assessment items directed a subject area based on a set of model items collectively directed to the subject area. The item generation interface may group the set of model assessment items into a plurality of similar item groups using numeric features corresponding to the model assessment items. Similar item groups may include model assessment items covering conceptually similar concepts within the subject area. A conditioning input may be generated for each of the item groups based on the numeric features corresponding to the model assessment items in the item group. Responsive to providing the conditioning inputs to a transformer-based natural language generation model, the item generation interface may receive raw assessment items from the transformer-based natural language generation model. Knowledge assessment items may be identified from the raw assessment items.

Abstract: Apparatuses, systems, and methods are disclosed for regulating an eversion process in everting sheath systems to avoid uncontrolled deployment of the sheath. The sheath system includes a reel and a sheath stored thereon, where the sheath is capable of everting from a retracted position to an extended position as the reel rotates about a rotational axis. The rotational characteristics of the reel are controlled by a torque mechanism operable to directly or indirectly apply a passive torque to the reel to adjust a rate at which the sheath is released from the reel as the sheath everts from the retracted position to the extended position.

Abstract: Disclosed is a signal processing method for a distributed acoustic sensing system (DAS), where a scattered signal that was scattered at a scattering location along an optical path is received and interfered with a local oscillator signal to generate a first carrier signal that is modulated by a phase difference between the local oscillator signal and the scattered signal. The first carrier signal is then digitally processed in order to generate a second carrier signal that is modulated by a spatial differential of the phase difference. The spatial differential of the phase difference is directly related to the strain (or acoustic environment) of the optical path at the scattering location, and so enables the strain at the scattering location to be estimated.

Abstract: A method includes capturing, via a camera that is inserted into a cavity, a first image of a surface defining the cavity and compressing the first image, using a compression algorithm, to generate a first feature vector. The method also includes identifying a second feature vector of a plurality of second feature vectors that best matches the first feature vector. The plurality of second feature vectors was generated by compressing second images of the surface using the compression algorithm. The second images were captured prior to insertion of the camera into the cavity and prior to capturing the first image. The method also includes generating, using the second feature vector, output indicating a position and/or an orientation of the camera as the camera captured the first image.

Abstract: Systems and methods for performing flash updates during runtime are discussed. More particularly, the amount of secure memory required to prevent tampering during the update process is limited by storing hashes of logical blocks of the update image in secure memory after initial validation while storing the update image in non-secure RAM or another non-secure memory location. Additionally, disruptions to the computing platform are limited by dividing the logical blocks into smaller progress units to minimize the amount of time spent in the secure operating environment performing the update.

Abstract: Techniques for image data protection using cyclic redundancy checks are disclosed herein. Some of the techniques may include, at a processor, receiving image data that includes multiple lines of pixel data. The processor may also determine at least a first hash value representing a first line of pixel data of the multiple lines of pixel data and a second hash value representing a second line of pixel data of the multiple lines of pixel data. The processor may also send the image data to a computing device that is configured to determine, based at least in part on the first hash value and the second hash value, whether the image data is corrupt.

Abstract: Performance anomalies in complex systems can be difficult to identify and diagnose. In an example, CPU-usage associated with one or more of the systems can be determined. An anomalous event can be determined based on the determined CPU-usage. In some examples, based at least in part on determining the event, the system may be controlled in a safe state and/or reconfigured to obviate the anomalous event.

In some examples, a process metric collection component may be associated with the scheduler and the processing resource such that the process metric collection component can capture real time data associated with the processes or threads both executed by the processing resource and waiting to execute on the processing resource. The captured data may be used by the system to monitor operations.

Abstract: A technique for sharing an application between devices is discussed. Embodiments of the present invention transmit information about an application from a source computing device to a target computing device. An application sharing service on the target computing device then automatically searches the target computing device for a resident corresponding application or its equivalent and if a corresponding application is not found, searches an application store or repository for the corresponding application. If the application or its equivalent is found in the application store or repository, a user may be prompted to download the application or the application may be downloaded automatically. If the corresponding application was found on the target computing device originally, a check may be performed to determine if the most recent update is installed and, if the most recent version is not installed, it may be downloaded from the application store.

Abstract: A vehicle may include a primary system and a secondary system to validate operation of the primary system and to control the vehicle to avoid collisions. For example, the secondary system may receive multiple trajectories from the primary system, such as a primary trajectory and a secondary, contingent, trajectory associated with a deceleration or other maneuver. The secondary system may determine if a trajectory is associated with a potential collision, if the trajectory is consistent with a current or previous pose, if the trajectory is compatible with a capability of the vehicle, etc. The secondary system may select the primary trajectory if valid, the secondary trajectory if the primary trajectory is invalid, or another trajectory generated by the secondary system if the primary trajectory and the secondary trajectory are invalid. If no valid trajectory is determined, the vehicle may decelerate at a maximum rate.
