Abstract: A device for multiplexing a wireless charging (WLC) coil for near-field communication (NFC) is provided. The device includes: the WLC coil with a first end, a second end, and a first contact point located between the first end and the second end; a first terminal connected with the first end of the WLC coil; a second terminal connected with the second end of the WLC coil; and a third terminal connected with the first contact point of the WLC coil, where the first terminal of the WLC coil is configured to be a first WLC terminal; the third terminal of the WLC coil is configured to be a first NFC terminal; and the second terminal of the WLC coil is configured to be multiplexed as a second WLC terminal and a second NFC terminal.

Abstract: The present disclosure provides a multi-factor quantitative analysis method for deformation of a neighborhood tunnel. The method includes the following steps: analyzing monitoring data generated at a tunnel site; simulating collapse occurring at a shallow buried section of a tunnel; determining the degree of influence of each factor on the tunnel and a stratum; and determining quantitative influence of each factor on tunnel deformation. The present disclosure can not only provide an accurate theoretical basis for the construction of the shallow buried section of the small-distance tunnel, but also guarantee safety and cost saving during tunnel construction.

Abstract: Embodiments of this application disclose a blocked antenna alarm method, and a communication chip and device that relate to the chip field. The embodiments resolve a problem where a communication device cannot prompt a user that an antenna of the communication device is blocked. In the method, the communication chip obtains an attenuation value of an air interface loopback signal through an antenna of the communication device. The communication chip then determines, based on the attenuation value, whether the antenna is blocked. When it is determined that the antenna is blocked, the communication chip indicates a processor of the communication device to output, to a user, alarm information indicating that the antenna is blocked.

Abstract: This application discloses a wireless chip, a signal receiving method, and a wireless communications apparatus, and relates to the wireless communications field, to improve a signal strength of a received signal obstructed by an object, and select a wireless radio frequency channel corresponding to an antenna with good directivity. The wireless chip includes: a first wireless radio frequency channel, coupled to a first antenna; a second wireless radio frequency channel, coupled to a second antenna; and a wireless baseband, coupled to each of the first wireless radio frequency channel and the second wireless radio frequency channel, and configured to selectively receive a signal transmitted by a transmitting device, through at least one of the first wireless radio frequency channel or the second wireless radio frequency channel. The wireless chip can be a Bluetooth chip.

Abstract: A lamp includes a lamp body; and an illumination assembly including a lamp shade assembly including a shade and a seat; and a lamp board. The seat is threadedly secured to the lamp body. The lamp board is secured to a lower end of the seat and laterally extends out of the seat. The lamp board serves as a bottom of the seat. The lamp board includes two first electrodes fastened on a bottom and a plurality of second electrodes adjacent to an edge. The first and second electrodes are electrically connected to positive and negative terminals of a control circuit of the lamp board respectively. The first and second electrodes are positive and negative terminals of a light source respectively. A clockwise rotation of the illumination assembly threadedly secures to the lamp body and turns on the light source.
