  • Patent number: 11825215
    Abstract: A multi-lens camera module making use of a single image sensor comprising first and second lens modules, an image acquisition module, a refracting module, and a shielding module. The refracting module refracts light from either the first lens module and/or the second lens module, the shielding module allowing light to enter only one of the first or second lens modules by masking the other. The first and second lens modules can share one image acquisition module, which saves cost and interior space of the camera module and thus of the electronic device using such camera module. An electronic device comprising the camera module is also provided.

  • Patent number: 11757109
    Abstract: The invention provides a hybrid power system, which integrates an internal combustion engine with a solid oxide fuel cell (SOFC) stack and provides power for the vehicle through the internal combustion engine at first in the preheating stage of the SOFC stack, thereby solving the problem that an SOFC stack is unable to provide power for the vehicle in the preheating stage. At the same time, the internal combustion engine burns fuel gas, outputs high temperature exhaust gas, heats the heat exchanger with the high temperature exhaust gas, then discharges the exhaust gas from an exhaust turbine and inhales air from the outside of the system. The air first passes through an air preheater, then passes through a heat exchanger and then enters the inside of the SOFC stack, preheats the air preheater through an air pipeline and then is discharged. After multiple cycles, the preheating of the SOFC stack is completed.

  • 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.
