This invention provides an antenna structure, especially relates to an antenna structure in hand-held device. The antenna structure of the present invention is formed by a continue transmission line, and forming an annular shape. It is featured that the antenna structure has two end points, the first end point is a floating point, and the second end point connected to a ground. A signal input point is connected to the continue transmission line for inputting an antenna signal into the antenna structure. The signal input point keeps two-thirds of wavelength distance from the second end point. According to present invention, a small antenna structure is provided and fitting in with operation in ultra wide bandwidth frequency, furthermore the multi-frequency signal can be transceived. The antenna structure has lower signal intensity of high order harmonic signals, therefore the structure can reduce the antenna signal interferences with the high order harmonic signals.

Antenna suitable in hand-held device

A remotely controllable receptacle system is disclosed. The remotely controllable receptacle system includes a remote control device for emitting a first request signal and a searching signal, and a plurality of receptacle devices for emitting a first reply signal according to the first request signal. The remote control device determines whether the first reply signal is received and the receptacle device emitting the first reply signal is classified as the vicinity receptacle device and the receptacle device not emitting the first reply signal is classified as the missing receptacle device. The vicinity receptacle device is configured to emit a second request signal according to the searching signal and determine whether the missing receptacle device emits a second reply signal according to the second request signal before a mutual communication between the remote control device and the missing receptacle device via the vicinity receptacle device is established.

Remotely controllable receptacle system and managing method for operating the same

A power saving apparatus and power saving method thereof are disclosed. The apparatus includes a power controller and a power outlet, wherein the power controller has a first signal transmission interface, said first signal transmission signal interface is used to detect the operation mode of a host machine by a second signal transmission interface of said host machine, and outputs a controlling signal according to the operation mode of said host machine. The power socket communicates with the power controller and switches the power-on or off according to the control signal. When the host machine is operated in non-working mode, the power socket will turn off the power supplied to the peripheral electrical devices of the host machines, so as to save the power consumption of the peripheral electrical devices of the host machines.

Power saving apparatus and power saving method thereof

A remote control system is disclosed. The remote control system includes a remote control transmitter module for transmitting a learning signal or a functional signal, and a remote control receiver module in a host for receiving the learning signal or the functional signal wherein the remote control receiver module operates in a learning mode upon a receipt of the learning signal or controls the host to operate functions according the functional signal. When the remote control receiver module operates in the learning mode the remote control receiver module is configured to verify and store the learning signal for recognizing an identity of the remote control transmitter module.

Remote control system and method for operating the same

A power system with light-controlled function and the control method thereof, which power system comprising a light sensor module, a first microprocessor, a wireless transmitter, at least one controlled socket, a wireless receiver and a second microprocessor. The light sensor module outputs a first electrical signal according to the brightness of light. The first microprocessor is coupled to the light sensor module and outputs a first control signal according to the first electrical signal. The wireless transmitter is coupled to the first microprocessor and transmits the first control signal to the wireless receiver. The second microprocessor is coupled to the wireless receiver and the aforementioned controlled socket so as to control the state of power supply in the above-said controlled socket according to the first control signal.
