  • Patent number: 11935634
    Abstract: A system for predicting and summarizing medical events from electronic health records includes a computer memory storing aggregated electronic health records from a multitude of patients of diverse age, health conditions, and demographics including medications, laboratory values, diagnoses, vital signs, and medical notes. The aggregated electronic health records are converted into a single standardized data structure format and ordered arrangement per patient, e.g., into a chronological order. A computer (or computer system) executes one or more deep learning models trained on the aggregated health records to predict one or more future clinical events and summarize pertinent past medical events related to the predicted events on an input electronic health record of a patient having the standardized data structure format and ordered into a chronological order.

  • Patent number: 11519380
    Abstract: A sea wave generating device includes a floating base, a generating assembly, a driving assembly, and a guiding housing. The floating base includes a base body and a cover plate. The generating assembly is secured in the base body and includes a lower magnetic wheel and a power generator. The driving assembly includes an upper magnetic wheel and a blade wheel. The upper magnetic wheel and the lower magnetic wheel are attracted magnetically. The guiding housing is secured to the base body and rests on the cover plate. The guiding housing covers the blade wheel and the upper magnetic wheel. Thus, when the sea wave is introduced into the guiding housing, the seawater pushes the blade wheel which drives the upper magnetic wheel which drives the lower magnetic wheel which drives the power generator to generate an electric power.
