A mobile terminal includes a body, and a flexible display screen disposed on the body. The flexible display screen is configured to be switched between an expanded state and a retracted state. A primary antenna is disposed within the body, and a spare antenna for replacing the primary antenna is disposed at an edge of the flexible display screen. The method includes: controlling the primary antenna to be in a working state and the spare antenna to be in a non-working state when the flexible display screen is in the retracted state; and controlling the primary antenna to be in a non-working state and the spare antenna to be in a working state when the flexible display screen is in the expanded state.

A computer implemented method, system and device are provided. The method transmits an energizing signal from an external antenna, coupled to a local external device (LED), to an implanted antenna of a passive implanted medical device (PIMD). The energizing signal is transmitted while the external antenna is at first and second positions. The method receives, at the external antenna, first and second energy transfer characteristic (ETC) values associated with the first and second positions, respectively. The method is under control of one or more processors configured with program instructions. The method analyzes the first and second ETC values to determine a difference therebetween. The method provides an energy transfer level (ETL) indicator based on the difference between the first and second ETC values. The ETL indicator provides feedback regarding a degree of energy transfer associated with at least one of the first and second positions.

The present disclosure provides an electronic device, a mobile terminal and an antenna assembly. The electronic device includes: a case defining an accommodating groove; a movable support slidably connected to the case, and capable of moving out of or retracting into the accommodating groove; and a first antenna installed on the movable support. Since the first antenna may be ejected out of the accommodating groove along with the movable support, influence of other components disposed inside the electronic device on the first antenna may be reduced. Thus, the implementation of the present disclosure may improve antenna performance of the electronic device.

A Planar Inverted-F Antenna, PIFA, comprises a sheet of conductive material including first, second, third and fourth contiguous sections, the first and third sections extending orthogonally away from the second section and the fourth section extending away from the third section. The sections are folded relative to one another to define a volume with a heights of the second section, a width of the second section, and a depth of the third section extending away from the second section. A supporting pin and a feed pin extend from the second section along an outer edge. A supporting leg extends from either the third or fourth sections, the supporting leg lying outside the plane of the supporting pin to support the PIFA when mounted on a printed circuit board, while allowing components to at least partially occupy the volume under the PIFA.

A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.
