This application relates to the field of mobile communications, and in particular, to a technical solution of sharing data with a nearby device by using a wireless communications technology. In a method for printing a photo, a mobile phone first selects a to-be-printed photo, then discovers a nearby device by using the foregoing related wireless communications technology, and displays the discovered device such as a printer or a projector on the mobile phone; and then a user performs a tap operation on the discovered printer, so that one-tap printing can be implemented. In this way, printing efficiency of an electronic device is improved, and user experience is also improved.

A thermoplastic composite component assembly and method of manufacturing the thermoplastic composite component assembly is disclosed. The thermoplastic composite component assembly is manufactured by first performing a molding step to form individual assembly features as discrete assembly feature components, and separately forming a thermoplastic composite component using a first compression molding step. Then, a reprocessing step is performed where the discrete assembly feature components are integrated with the thermoplastic composite component using a second compression molding step. The reprocessing step essentially 'welds' the discrete assembly feature components to the thermoplastic composite component at each of a plurality of desired assembly feature sites.

A body coil includes a first end ring and a second end ring provided at two ends thereof. The first end ring and the second end ring are connected to each other with a plurality of legs. The first end ring or the second end ring has a structure with the current flow width in a direction parallel to the axis thereof being greater than that in a direction perpendicular to the axis thereof. Since the effective action width of the current is increased in the axial direction and the centralized flow of the current in the end ring is reduced, the local specific absorption rate of radio frequency induced by the magnetic field is therefore reduced.
