摘要： A base station and a handover control method thereof are provided. The base station supports dual connectivity (DC) technology. The method includes the following steps. A handover request is transmitted, and a handover request response corresponding to the handover request is received. Whether the handover request response includes DC information is determined. In response to the handover request response not including the DC information, the DC information related to releasing a DC configuration is generated, and a handover command including the DC information is transmitted. The handover command corresponds to the handover request response. Accordingly, user equipment can be informed to release the DC configuration, so as to reduce power. In addition, a proper resource configuration would be provided.

摘要： The disclosure provides a communication device including a ground plane, an antenna and an extended grounding structure. The ground plane has a first side and a second side opposite to each other. The antenna is disposed at the first side and has a first feeding end. The extended grounding structure is disposed at the second side and includes a connection portion and a symmetrical structure. The symmetrical structure is electrically connected to the ground plane via the connection portion, wherein the symmetrical structure is symmetrical along a symmetry axis, and an extension line of the symmetry axis passes through the first side and the second side. The disclosure can effectively prevent antenna efficiency from being degraded due to an insufficient size of the ground plane, so as to significantly enhance communication quality.

摘要： A video doorbell system comprising a video doorbell device, which comprises a chime trigger device, a first battery, an AC power receiving interface, an AC to DC circuit, a charging circuit, a DC power receiving interface and an image capture circuit. The first battery provides an internal DC voltage. The AC power receiving interface receives an AC voltage. The AC to DC circuit converts the AC voltage to a second DC voltage. The charging circuit drains the second DC voltage to charge the first battery. The DC power receiving interface receives a first DC voltage. The image capture circuit selectively drains the internal DC voltage, or the first DC voltage to operate.

摘要： A broadband antenna is provided. In the broadband antenna, the first end of a first radiation member is connected to the first end of a second radiation member to form a first commonly-connected end, and the second end of the first radiation member is connected to the second end of the second radiation member to form a second commonly-connected end, wherein the first commonly-connected end has a feed point, the second commonly-connected end is connected to a ground member, and the first radiation member is surrounded by the second radiation member and is spaced apart from the second radiation member by a gap. As a result, the broadband antenna can provide 2 frequency bands, each having ½ wavelength resonant mode in a frequency range less than 1 GHz, without the occurrence of resonant mode degradation.

摘要： The IP Camera of the present invention includes a housing, a heat conducting component, a base and a supporting structure. The heat conducting component is disposed inside the housing to directly contact a heat generating component. The base can be put on or fixed onto a supporting plane, so as to hold a weight of the IP Camera by the supporting plane. An end of the supporting structure extends through the housing to directly contact the heat generating component, and the other end of the supporting structure extends into the base. The heat conducting component and the supporting structure are used to be an uninterrupted heat conduction path between the heat generating component and the base, and a coefficient of heat conductivity of the uninterrupted heat conduction path is greater than 5W/m*K, so that the IP Camera has preferred heat dissipating efficiency.
