  • Patent number: 11959826
    Abstract: The disclosure is an engine simulation test device capable of realizing an ultrahigh compression temperature and pressure, belonging to the field of a diesel engine high-temperature and high-pressure system, solving the problems that the existing engine simulation test cannot achieve ultra-high compression temperature and pressure, and the temperature and pressure are not adjustable. It includes a compressed air inlet mechanism, a nitrogen gas inlet mechanism, a pressure stabilizing mechanism, a cyclic heating mechanism, an air inlet mechanism and a fast compressor mechanism.

  • 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: 11454203
    Abstract: The present disclosure provides an apparatus for testing spray and combustion performance of an internal-combustion engine based on a rapid compression-expansion machine, which belongs to the testing field of internal-combustion engines. It includes a driving mechanism, a transmission mechanism, an engine cylinder, an air intake system and an exhaust system. The engine cylinder includes a piston, a cylinder block, a dual-fuel cylinder head and a multi-injector assembly. The piston is disposed in the cylinder block. The driving mechanism is connected with the piston through the transmission mechanism and drives the piston to linearly move back and forth along a vertical direction of the cylinder block. The dual-fuel cylinder head is connected to an upper part of the cylinder block. The multi-fuel injection assembly includes a plurality of injectors. The plurality of injectors are of the same type and are all disposed on the dual-fuel cylinder head.

    Abstract: The present disclosure provides an apparatus for testing spray and combustion performance of an internal-combustion engine based on a rapid compression-expansion machine, which belongs to the testing field of internal-combustion engines. The present disclosure solves the problems that the existing test of the internal-combustion engine testing apparatus having a complex structure, is poor in adaptability, cannot be observed easily, and cannot meet the requirements of multi-fuel injection and multi-injection-pressure tests. It includes a driving mechanism, a transmission mechanism, an engine cylinder, an air intake system and an exhaust system. The engine cylinder includes a piston, a cylinder block, a dual-fuel cylinder head and a multi-injector assembly. The piston is disposed in the cylinder block. The driving mechanism is connected with the piston through the transmission mechanism and drives the piston to linearly move back and forth along a vertical direction of the cylinder block.
