  • Patent number: 12226194
    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.

  • Patent number: 11703925
    Abstract: An outdoor device reset system includes a voltage regulation apparatus coupled to a power supply apparatus and an outdoor device coupled to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate a working voltage input to the outdoor device based on a feedback signal, a supply voltage from the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus. The outdoor device is configured to determine a change amount of the working voltage, and perform a reset operation when the change amount is within a preset range.

  • Publication number: 20220236780
    Abstract: This application provides an outdoor device unit reset system, to resolve a problem in a conventional technology that an outdoor device unit needs to be reset by using a reset switch on the outdoor device unit. The system includes a voltage regulation apparatus connected to a power supply apparatus and an outdoor device unit connected to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate, based on a detected feedback signal, a supply voltage provided by the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus, a working voltage input to the outdoor device unit. The outdoor device unit is configured to: determine a change amount of the working voltage input to the outdoor device unit, and perform a reset operation when the change amount is within a preset range.

  • Patent number: 11258492
    Abstract: A high-speed data transmission degradation method, a device, and a system, to implement, in high-speed data transmission and depending on a terminal requirement, resource degradation in which interaction load is low and a terminal remains connected to a network, so as to ensure a data transmission rate of the terminal and improve terminal user experience. The method includes receiving, by a network-side device, a degradation request sent by a terminal that is in a high-speed data transmission mode; obtaining, by the network-side device, a target to-be-degraded resource of the terminal based on the received degradation request; and degrading, by the network-side device, the target to-be-degraded resource.
