Abstract: An energy Internet system, an energy routing conversion device, and an energy control method, relating to a field of energy information. An alternating-current (AC) side energy routing conversion device of the energy Internet system includes a plurality of first route ports, and a direct-current (DC) side energy routing conversion device includes a plurality of second route ports, where each second route port is connected to a corresponding first route port by means of a corresponding DC busbar. A plurality of energy devices are connected to a DC busbar by means of corresponding first AC/DC converters or first DC converters. The AC side energy routing conversion device and the DC side energy routing conversion device collect energy information of the energy devices and adjust energy of the energy devices on a basis of energy balance constraint conditions.

Abstract: Disclosed is a cardiac diastolic function assessment method applicable to the field of cardiac monitoring. The method comprises: acquiring vibration information of the thoracic cavity body surface of an object in a noninvasive manner; preprocessing the vibration information to generate hemodynamic-related information; determining a target wave group on the basis of the hemodynamic-related information; determining the highest peak on the target wave group, determining a rising edge amplitude before the highest peak as a first characteristic value, and determining, as a second characteristic value, an amplitude between the highest peak and the subsequent lowest valley; and generating an indicating parameter on the basis of the first characteristic value and the second characteristic value, and assessing a cardiac diastolic function of the object on the basis of the indicating parameter.

Abstract: A cardiac diastolic function assessment method, for use in the field of cardiac monitoring. The method comprises: noninvasively acquiring vibration information of the thoracic body surface of a subject; preprocessing the vibration information to generate hemodynamics-related information; determining a first parameter and a second parameter on the basis of the hemodynamics-related information; generating an indicating parameter on the basis of the first parameter and of the second parameter, and assessing the cardiac diastolic function of the subject on the basis of the indicating parameter.

Abstract: A method for evaluating cardiac diastolic function, which applies to the field of cardiac monitoring. The method comprises: obtaining vibration information of the surface of the thoracic cavity of a subject by means of one or more optical fiber sensors; preprocessing the vibration information to generate hemodynamic related information; performing high-frequency component extraction on the hemodynamic related information to generate high-frequency component information; determining a first feature value and a second feature value based on the hemodynamic related information and the high-frequency component information; generating indicating parameters based on the first feature value and the second feature value, and evaluating the cardiac diastolic function of the subject based on the indicating parameters.

Abstract: A key of an electronic device and an electronic device applying the key are provided. The key includes a key cap and a substrate arranged under the key cap, the key cap and the substrate are formed separately, and the substrate is adhesively attached to an underside of the key cap with an adhesive.

Abstract: Provided is a mobile terminal. The present application provides a sensor inside either or both of a receiver opening and a microphone opening, rather than providing an additional opening on the front panel of a device for installing the sensors, such that light is transmitted to the sensor via the receiver opening and/or the microphone opening, and the sensor transmits a signal via the receiver opening and/or the microphone opening; the receiver opening and/or the microphone opening are openings currently available on the front panel of the device, without the need of proving additional openings on the front panel of the device, reducing the number of the openings on the front panel of the device to make a mobile device more integrated, and provide a better user experience due to an uncluttered surface of the front panel of the device.
