Abstract: A method for determining natural illumination duration and an electronic device are provided, to more accurately determine a scenario in which a user is located and effectively determine natural illumination duration, to help the user improve vision. The method is applied to an electronic device having a display screen and includes: determining a current scenario based on a preset reference factor (S901), where the preset reference factor includes any one or more of ultraviolet intensity, illumination intensity, and locating signal strength; and counting current natural illumination duration towards cumulative natural illumination duration if the current scenario is a preset scenario (S902), where the preset scenario includes any one or more of an outdoor scenario, an indoor near-window scenario, and an outdoor blocked scenario.

Abstract: The present invention relates to the field of communications technologies and discloses a phase shifter and a feed network. The phase shifter includes at least one phase shift component. The phase shift component includes a substrate, a microstrip coupling structure disposed on a first plane of the substrate, a microstrip transmission line connected to and coplanar with the microstrip coupling structure, and a microstrip/coplanar-waveguide coupling structure, where the microstrip/coplanar-waveguide coupling structure includes a microstrip connected to and coplanar with the microstrip transmission line, and a coplanar waveguide disposed opposite to the microstrip on the substrate and coupled with the microstrip. A phase shifter using a microstrip/coplanar-waveguide coupling structure has a small volume and costs low, thereby facilitating feed network design.

Abstract: This application provides a dispersion compensation method, an apparatus, and a storage medium. The method includes: obtaining a subcarrier allocation result, where the subcarrier allocation result includes subcarriers allocated to at least two receive ends based on signal-to-noise ratio results of signals transmitted between the transmit end and at least two receive ends; compensating, based on a correspondence between a communication distance and dispersion compensation value, a subcarrier allocated to each receive end for a dispersion compensation value corresponding to a first communication distance and, to obtain a compensated signal; adding a cyclic prefix CP to the compensated signal; compensating a frequency-domain subcarrier corresponding to the signal to which the CP has been added, for the dispersion compensation value corresponding to a second communication distance. This application effectively alleviate a fading phenomenon caused by fiber dispersion, and help improve performance of an optical communications system.

Abstract: Example methods and devices for blood pressure measurements are disclosed herein. The example methods include determining whether to perform blood pressure measurement on a user, and determining a blood pressure measurement mode used to perform the blood pressure measurement based on a degree of impact on a sleep status of the user. In a first measurement mode, the user needs to be prompted to adjust a blood pressure measurement posture to meet a blood pressure measurement requirement. After the user confirms that the posture is adjusted, blood pressure measurement is performed on the user. In a second measurement mode, blood pressure measurement can be performed on the user without prompting the user to adjust a blood pressure measurement posture.

Abstract: A method for accessing data is provide, the method includes: receiving a first address and identification information used to identify an address type; and when the identification information indicates a logical address type, converting the first address into a first physical address, and accessing at least one corresponding flash memory chip in the storage device; or when the identification information indicates a physical address type, directly accessing at least one corresponding flash memory chip in the storage device. When the storage device is accessed, a type of an accessed address is determined according to the identification information. If the address is a logical address, the storage controller maps the logical address to a physical address and accesses the physical address; or if the address is a physical address, the storage controller directly accesses the physical address sent by the host.
