Abstract: An exercise assisting device includes at least one processor. The processor obtains motion data on a current exercise form of a user performing a certain repetitive exercise motion including a certain motion state. Based on the obtained motion data, the processor determines a point of time at which the motion state occurs in one cycle of the repetitive exercise motion. Based on the obtained motion data and the point of time, the processor obtains the current exercise form in the motion state. The processor obtains a difference between the obtained current exercise form and a target exercise form. The processor causes an actuator to apply a stimulus to a body of the user based on the difference. The actuator is attached to a part of the body of the user constituting the exercise form. The stimulus suggests correction of the exercise form and indicates a direction to move the part.

Furthermore, the simulation system is configured to send instructions to the embedded system, which cause the embedded system to simulate the injury such that the simulation reflects the treatment.

Abstract: Systems and methods may involve processing of entity data by nested machine learning models to produce one or more aggregate risk scores, which may be compared to one or more thresholds to determine when one or more predefined actions should be taken. The entity data may be collected for various entities related to an exam registration and delivery process, which may include a candidate, an exam, a test center, an exam registration event, a proctor, and an exam delivery event. Entity data for each entity may be separately processed by entity-specific machine learning models to generate intermediate entity risk scores. The intermediate entity risk scores may be input to an aggregate machine learning model, which may output an aggregate risk score. A resource management server may cause the predefined actions to be taken after comparing the aggregate risk score to the one or more thresholds.

Abstract: A surgeon training apparatus includes a cassette, which includes biological tissue repurposed into a form consistent with the anatomical configuration of abdominal hernias, affixed into an anatomically correct silicon framework which replicates the abdominal anatomy. The framework positions the cassette in an anatomically correct position within the abdominal cavity, enabling surgeons to train using a properly positioned representation of the target anatomy, thus requiring the surgeon to properly use surgical tools to correct the pathologic condition caused by the hernia. The cassette is formed by applying biologic tissue to a specially designed “plate,” which affixes the tissue block into the anatomic framework, and is adapted for connection to a grounding device so the surgeon can use cautery during the simulated hernia repair.
