Abstract:
A folder management method and device. The method includes: displaying a folder icon comprising a set of icons of at least two applications, and the set of icons is displayed as a thumbnail icon, and, in the thumbnail icon, each of the icons of the at least two applications is displayed in a shrunk size, and the folder icon further comprising an enlarged first icon associated with a first application, wherein the enlarged first icon is displayed adjacent to the thumbnail icon without the first icon, and wherein a size of the enlarged first icon is a same size as the thumbnail icon. The first application is determined according to a use time sequence or other factors. In this way, icons, of some applications, in the folder icon can be enlarged for display, which facilitates management of applications in the folder.
Abstract:
A folder management method and device. The method includes: displaying a folder icon on the touchscreen display, and displaying a drag mark in a first position of the folder icon; detecting a first drag operation to the drag mark, where the first drag operation is used to increase a size of an icon of an application in a folder; and when the first drag operation is detected, displaying, on the touchscreen display, an icon that is of at least one application in at least two applications and that is inside the folder icon, where the icon is enlarged for display. In this way, icons, of some applications, in the folder icon can be enlarged for display, which facilitates management of applications in the folder.
Abstract:
The present invention is applicable to the communications field and provides a processing method for an orthogonal frequency division multiplexing (OFDM) signal and a network device. The processing method includes: obtaining an orthogonal frequency division multiplexing OFDM signal; multiplying, in a digital domain, the obtained OFDM signal by a simple harmonic wave whose frequency is fs to obtain a frequency shifted signal; and outputting and loading the frequency shifted signal by using a digital-to-analog conversion (DAC) to a driver and a modulator to send the frequency shifted OFDM signal.
Abstract:
In accordance with an embodiment, an earphone includes: a housing having a cavity structure disposed within, and a sound output port in communication with the cavity structure; and a first sound transducer, a second sound transducer, and a third sound transducer disposed in the cavity structure, wherein: a sound production frequency of the second sound transducer is greater than a sound production frequency of the third sound transducer and is less than a sound production frequency of the first sound transducer, and the third sound transducer is a micro-electro-mechanical-system located between the first sound transducer and the sound output port.
Abstract:
A VRRP fault detection method is applied to a VRRP group including one primary router and one or more secondary routers. The method includes: sending, by the primary router and the secondary router, link detection packets having an echo response function, where a destination address of the link detection packet is a virtual address of the VRRP group. The method also includes determining, by the primary router and the secondary router, whether response packets corresponding to the link detection packets sent by the primary router and the secondary router are received within a predetermined time, and if the primary router and/or the secondary router does not receive the response packet within the predetermined time, determining that the primary router is faulty.
Abstract:
According to a transmitter, a receiving device, and a frequency offset correction method that are provided in embodiments of the present invention, after a power parameter of a pilot in an OFDM signal received by a receiving device is detected, a frequency offset value used to indicate a degree and a direction that are of a difference that is between a center frequency of a filter and a center frequency of a laser and that deviates from a first threshold is determined according to the power parameter of the pilot, and then the receiving device corrects the difference between the center frequency of the laser and the center frequency of the filter according to the determined frequency offset value, thereby implementing frequency offset correction of an OFDM system.
