Abstract: User equipment includes a first antenna, a second antenna, a first transceiver coupled to the first antenna, a second transceiver coupled to the second antenna, and processing circuitry communicatively coupled to the first transceiver and the second transceiver. The first transceiver receives or transmits a first signal via the first antenna, and the second transceiver receives or transmits a second signal via the second antenna. The processing circuitry receives an indication that a signal characteristic of the first signal is less than a first threshold, and decreases power to the first antenna, the first receiver, or both, based on the signal characteristic of the first signal being less than the first threshold.

Abstract: The present disclosure provides a shielding apparatus for a lower end of an injection needle and an injection device, and relates to the technical field of injection instruments. By using the shielding apparatus for a lower end of an injection needle in the present disclosure, in the process of mounting a needle holder on an insulin pen, and when the injection needle is completely removed from the insulin pen, the limit block also moves downwardly to abut against a bottom wall of the moving groove, and the shielding cylinder completely covers the lower end of the injection needle, so as to avoid a situation that a user accidentally touches the lower end of an injection needle to be injured, thereby avoiding the safety risk when the lower end of the injection needle is removed.

Abstract: The present disclosure provides a safe puncture needle, and relates to the technical field of medical devices, which comprises a needle holder, a base and a needle tubing, wherein the needle tubing comprises a needle tubing body and a needle tubing tip having a bent structure, the base comprises a base body and a guide block, the base body is provided with a second inner space, the base body is provided with a first through-hole and a second through-hole communicating with the second inner space, the guide block is provided with a third through-hole, the needle tubing body passes through the first through-hole and the third through-hole and is slidably connected to the guide block, and the needle tubing tip retracts from the second through-hole.
