Abstract: An electronic device, and the electronic device includes: a frame body, a display, and an antenna coupling structure. The display is disposed on the frame body, and a display control line is disposed on a side, close to the frame body, of the display. An antenna resonant arm is disposed on the frame body, and the antenna resonant arm includes a first antenna and a second antenna. Operating frequency bands of the first antenna and the second antenna are different, and a gap is formed between the antenna resonant arm and the display control line. A clearance area is provided at a position, close to the gap, on the frame body, the antenna coupling structure is disposed in the clearance area, and the antenna coupling structure is coupled to an antenna reference ground on the frame body.

Abstract: An apparatus for protecting a utility pole from wildfires is disclosed. The apparatus comprises a plurality of layers comprising a fiberglass and at least one adjacent layer comprised of glass fiber cloth. The two ends of each of the two outer layers may further comprise connectors connected to surround the outer side of the utility pole.

Abstract: A fire-resistant utility pole sleeve comprising two fire-resistant layers with a semicircular cross section for sleeving an outer side of a pole. Two ends of each of the fire-resistant layers comprise connectors and the fire-resistant layers are operable to be connected to each other through the connectors. Inner layers and outer layers of the fire-resistant layers are support protection layers. A ceramic fiber material may fill a gap between the support protection layers. The fire-resistant utility pole sleeve in a preferred embodiment may effectively protect a wooden pole, a steel pole and a composite pole by providing fire-resistant performance of the poles and may be mounted on previously deployed poles in areas prone to wildfires to protect the poles from fire damage.

Abstract: The embodiments of the present invention disclose a method and user terminal for receiving multicast control channel (MCCH) change notifications, which include: obtaining the transmission time of an MCCH change notification; and when the MCCH change notification is not received during one MCCH modification period, receiving, according to the transmission time of the MCCH change notification, the MCCH change notification at least N times, wherein N is the preset reception times of the MCCH change notification. In the present invention, the efficiency of receiving MCCH change notifications by user terminals is improved, and the probability of processing MCCH change notifications falsely due to too many network identifiers in a physical downlink control channel (PDCCH) is reduced.
