    摘要: A wireless communication method and devices, capable of achieving backscattering communication of zero-power devices on TDD spectrum. The method includes: a terminal device receives a signal transmitted from a first device, the signal is configured for powering the terminal device and/or for backscattering communication by the terminal device, and the first device being a device other than a network device that provides services to the terminal device.

    摘要: Embodiments of this application are applicable to the field of communication technologies, and provide a stereo networking method, an electronic device, an audio device, and a storage medium. In a system including the electronic device and the audio device, the audio device generates a Bluetooth broadcast message and sends to the electronic device, where the Bluetooth broadcast message indicates whether the audio device has established stereo and whether the audio device is allowed to establish stereo. When determining, based on the Bluetooth broadcast message, that a second audio device available for establishing stereo exists, the electronic device pops up a stereo establishment pop-up box, to ask a user whether to allow the electronic device to establish stereo or re-establish stereo. Based on short-range communication, the electronic device may directly and automatically discover an audio device available for establishing stereo, and establish stereo with the audio device based on a user requirement. This implements higher flexibility and efficiency of stereo networking and improves user experience.

    摘要: The present invention relates to a device for transmitting data and, particularly, to a device for transmitting data by using a magnetic stripe method. According to one embodiment of the present invention, the magnetic stripe data transmission device comprises: a coil to which a current is supplied in a first direction and a second direction, which is opposite to the first direction; a core for inducing a magnetic field when the current is supplied to the coil; a power source for supplying the current to the coil; driving units for intermittently supplying, to the coil, in the first direction or the second direction, a burst pulse or pseudo-burst pulse current supplied from the power source; and a control unit for outputting, to the driving units, a control signal in order to perform control such that the current is supplied to the coil alternately in the first direction and the second direction, wherein the core can be made of a material having an aspect ratio value of at least 0.5, having a coercivity value of 1000-10,000 [A/m], and having pseudo-hard magnetic density of which the saturated magnetic flux density value is at least 1 [T].
