Abstract: An electronic device includes a metal back cover, a metal frame, a first antenna module and a second antenna module. The metal frame includes a first and a second disconnection portion, a first and a second connection portion. The first and the second connection portion are connected to the metal back cover. The first disconnection portion is separated from the first connection portion, the metal back cover and the second disconnection portion to form a first slot. The second disconnection portion is connected to the second connection portion and is separated from the metal back cover to form a second slot. The first antenna module is connected to the first disconnection portion, and forms a first antenna path. The second antenna module is connected to the second disconnection portion, and forms a second and a third antenna path with the second disconnection portion and the metal back cover.

Abstract: A charging device and associated electrical appliances are provided. More than one electronic device can be charged simultaneously, with a wireless charging option available. Thus, the user has greater flexibility in selecting the desired charging option. Each associated appliance has a receiving compartment to hold the charging device, and the receiving compartment is configured with at least one first terminal. The charging device has at least one electrical interface for cable connection, a wireless charging transmitter, and at least one second terminal for mating electrically to the first terminal.

Abstract: A modular electrical connector module includes an outer panel, an outlet box and an interchangeable socket module. The interchangeable socket module has at least one connector and is disposed in the outlet box yet demountable. The interchangeable socket module is exposed to the exterior via an opening defined by the outer panel for easy maintenance accessibility.

Abstract: A USB device using a rotatable USB connector includes a cable, a first USB plug, a second USB plug and a rotatable USB connector. The cable has a tail end, a first branch end and a second branch end. The first USB plug connects the tail end, the second USB plug connects the second branch end and the rotatable USB connector connects the first branch end. The rotatable USB connector has a first insulating main body, a second insulating main body, a plurality of first conductive terminals and a plurality of second conductive terminals. The first insulating main body and blades form a first connector module while the second insulating main body and blades form a second connector module. The USB 2.0 and second connector modules are movably connected via a joint.

Abstract: A functional control adapter for light generating devices includes a female portion, a male portion, and a control module. The female portion has an inlet body. The inlet body has a housing member having a first contact module. The male portion has an outlet body connected to the inlet body. A second contact module is disposed on the exterior of the outlet body. The control module is located at the inlet body and connected electrically to the first contact module of the female portion and the second contact module of the male portion. The adapter and the light source are joined separately, thus the lighting device can be dismounted or installed with convenience, and individual parts can be replaced as needed for reducing repair cost.

Abstract: An I2C multi-slot circuit system includes a plurality of I2C slots for receiving a plurality of slave processors, a CPU, a logic control unit, and a I2C switch unit. The CPU determines an address of one of the I2C slots which to-be-transmitted data will be transmitted to, and generates a first logic control signal according to the determined address. The logic control unit enables the one of the I2C slots which the to-be-transmitted data will be transmitted to according to the first logic control signal. The I2C switch unit receives and transmits I2C signal converted from the to-be-transmitted data by the CPU to the I2C slot. A related method is also provided.

Abstract: A USB connector is disclosed, which includes a first insulating body, a second insulating body, a plurality of first and second terminals, a first cover, and a second cover. A first module is defined by the first insulating body, the first terminals, and the first cover. A second module is defined the by second insulating body, the second terminals, and the second cover. The first and second modules are movably coupled relative to each other, for using independently or jointly.
