The back cover and the housing body are engaged with each other through the adsorption action between the first adsorption component and the second adsorption component, and a cavity structure is formed between a second end of the back cover body and the housing body.

Methods, apparatus, systems and articles of manufacture to monitor mobile devices are disclosed. An example apparatus includes a shell having a form factor dimensioned to receive a mobile device; and a near-field interceptor coupled to the shell, the near-field interceptor to capture data communicated via a near-field energy field between a first near-field communication device of the mobile device and a second near field communication device external to the mobile device.

A mobile electronic device includes a main framework, back cover, expansion box, card reading module and battery module. The main framework has a motherboard. The back cover is disposed on the main framework and has an expansion window. The expansion box covers and closes the expansion window. The expansion box has therein an expansion chamber, a power chamber, and a communication opening whereby the expansion chamber and the power chamber communicate with each other. The expansion box has a wire connection opening in communication with the power chamber and with the expansion window. The card reading module and battery module are disposed in the expansion chamber and power chamber, respectively. The card reading module is connected to the motherboard by a signal wire via the communication opening and the wire connection opening. The battery module is connected to the motherboard by a power wire via the wire connection opening.

A separated communications device includes a body and a movable connector; the body includes an antenna and a first conductive strip, and the antenna is electrically connected to the first conductive strip; the movable connector includes a second conductive strip; when the movable connector is connected to the body, a part, covered by the movable connector due to the connection, on a surface of the body is a connection position of the body; and the antenna is disposed on the body near the connection position. When the body is connected to the movable connector, the second conductive strip is connected to the first conductive strip, so that the first conductive strip serves as a part of the antenna, and the second conductive strip serves as an extended part of the antenna.

According to one embodiment, a memory system includes a nonvolatile semiconductor memory device, controller, memory, wireless communication function section, and extension register. The controller controls the nonvolatile semiconductor memory device. The memory is serving as a work area of the controller. The wireless communication module has a wireless communication function. The extension register is provided in the memory. The controller processes a first command to read data from the extension register, and a second command to write data to the extension register. The extension register records, an information specifying the type of the wireless communication function in a specific page, and an address information indicating a region on the extension register to which the wireless communication function is assigned.

A mobile terminal includes a hand-held portion and a body portion. The hand-held portion includes a first wireless communication module, a display screen, and a first power module electrically connected to the first wireless communication module and the display screen. The body portion includes a camera module, a second wireless communication module, a third communication module, and a second power module. The second power module is electrically connected to the camera module, the second wireless communication module, and the third wireless communication module. The third wireless communication module is configured to communicatively connect to an external device. The body portion defines a receiving space. The hand-held portion is received into or taken out of the receiving space. After being taken out of the receiving space, the second wireless communication module is communicatively connected to the first wireless communication module.

A remote-control includes a remote-control body, a first antenna, and a second antenna. The remote-control body includes a control device for a user to input a remote-control command. The first antenna and the second antenna are provided at a top side of the remote-control body and rotatably connected to the remote-control body to be extended in a use state or folded in a contracted state. The first antenna and the second antenna rotate to a position pointing to the user in the use state, and the first antenna and the second antenna are configured to be stacked and arranged parallel to each other in the contracted state.
