  • Patent number: 11730301
    Abstract: A steam cooking device which includes a pressure accumulating steam boiler and a steaming cabinet is disclosed. The pressure accumulating steam boiler heats liquid water and accumulates a steam having a pressure between 1.1 and 5.0 times atmospheric pressure. The steaming cabinet receives the steam from the pressure accumulating steam boiler to cook a foodstuff contained therein. To raise the temperature of a foodstuff accommodating chamber within the steaming cabinet from a room temperature to a cooking temperature, a WH1 amount of energy is consumed by an electricity-heat conversion unit in the pressure accumulating steam boiler. A foodstuff accommodating chamber within the steaming cabinet has a volume of V1. The steam cooking device satisfies V1/WH1>160. The cooking temperature is between 101° C. and 150° C. and is lower than or equal to the temperature of the steam when the steam is outputted from the pressure accumulating steam boiler.

  • Publication number: 20230259813
    Abstract: A method of automatically tuning hyperparameters includes receiving a hyperparameter tuning strategy. Upon determining that one or more computing resources exceed their corresponding predetermined quota, the hyperparameter tuning strategy is rejected. Upon determining that the one or more computing resources do not exceed their corresponding predetermined quota, a machine learning model training is run with a hyperparameter point. Upon determining that one or more predetermined computing resource usage limits are exceeded for the hyperparameter point, the running of the machine learning model training is terminated for the hyperparameter point and the process returns to running the machine learning model training with a new hyperparameter point. Upon determining that training the machine learning model is complete, training results are collected and computing resource utilization metrics are determined.

  • Publication number: 20230261564
    Abstract: A charging device and a safety function control circuit and method thereof are provided. When a charging device is not connected to a load, a converted voltage value of a power connection terminal of the charging device is kept to be lower than a safe voltage value so as to maintain a safe mode. The safety function control circuit includes a first control module and a second control module for constant voltage control. The first control module and the second control module perform matching control on a power conversion circuit of the charging device, and in case of a single fault of one of the control modules, the other module is still capable of keeping the converted voltage value to be less than the safe voltage value. Thus, it is ensured that the safe mode stays functional in case of a concurrency of both a single hardware fault and a single firmware fault.
