Abstract: A structure containing an antenna with an orientation which can be changed when one part of a two-part structure is turned relative to the other on a rotating shaft includes first and second structures as the two parts. The second structure is rotatably connected to the first structure through the rotating shaft, and the second structure comprises an antenna plate. When the second structure is rotated relative to the first structure, the rotated antenna plate allows a wider range of wavelength frequencies within the rotation range of the second structure.

Abstract: A wind comb capable of adjusting the direction of wind includes a housing, multiple first teeth, multiple second teeth, a baffle, and a driving unit. The housing defines a first receiving cavity. The first tooth and the second tooth define a first and a second wind channel respectively, which are communicating with the first receiving cavity. A direction of wind blowing from the first wind channel is different from that of the wind blowing form the second wind channel. The baffle defines multiple first and second vents. Each first vent is communicating with a first wind channel, each second vent is communicating with a second exhaust. The driving unit is used to drive the baffle to cause the first vent to communicate with or isolate from the first wind channel, and to cause the second vent to communicate with or isolate from the second wind channel.

Abstract: A ceiling-mounted base station with aesthetic contours includes a housing assembly and a shielding assembly. The housing assembly includes a first housing and a second housing connected to the first housing. The first housing includes first portion, third portion, and second portion connected in that order. The first portion and the second portion are disposed on opposite surfaces of the third portion. The third portion defines a cable hole. The shielding assembly is disposed on the second portion and connected to the second portion or the third portion. The shielding assembly, the second portion, and the third portion cooperatively define a shielding cavity with an opening facing the exterior, the shielding cavity can receive cables.
