Abstract: A multi-part apparatus and a data transmission method thereof are provided. The method is adapted to a multi-part apparatus having a master apparatus and a separable slave apparatus. The master apparatus and the slave apparatus are attached to each other through magnetism, and each of them has a wireless transmission module and a plurality of pins disposed on a side. In this method, a variation of the magnetism is detected, so as to determine a relative position between the master apparatus and the slave apparatus. When the master apparatus and the slave apparatus are attached to each other with a shift, a wireless connection set up by the wireless transmission modules is used for data transmission; and when the master apparatus and the slave apparatus are connected to each other with the sides thereof, both the wireless connection and the pins are used for data transmission.

Abstract: A portable electronic device including a first body, a second body, and an assembling structure is provided. The assembling structure includes a first assembling unit and a second assembling unit. The first assembling unit is adapted to hidden in one of the first and the second bodies, and the second assembling unit is disposed and hidden in another one of the first and the second bodies. When the first body is close to the second body, the first assembling unit is protruded out of the first body or the second body, and assembled to the second assembling unit, such that the first and the second bodies are fixed to each other.

Abstract: A wireless telecommunication device is disclosed. The wireless telecommunication device includes a printed circuit board, an antenna, an insulating layer, and an electrostatic discharge layer. The antenna is electrically coupled with the printed circuit board for transmitting a wireless signal received or sent by the printed circuit board. The insulating layer is disposed between the printed circuit board and the electrostatic discharge layer. At least a clean area exists in the electrostatic discharge layer and the clean area is configured corresponding to the source area of high frequency noises on the printed circuit board. The purpose of the clean area is to create a leaking channel for high frequency noises and decrease the interference toward the antenna from high frequency noises.

Abstract: An antenna assembly includes a base board having upper and lower surfaces, each of which defines a grounding domain and a dielectric domain, a first metal layer disposed on the grounding domain of the lower surface and a second metal layer disposed on the grounding domain of the upper surface, an antenna unit fabricated on the dielectric domain of the upper surface of the base board, and having an antenna body; and a plurality of conductive through holes formed through the base board for connecting electrically the first and second metal layers, thereby permitting coupled current flow generated in the second metal layer to flow into the first metal layer. A slot of predetermined length is formed through the first metal layer for enhancing effective coupled current flowing into the first metal layer.

Abstract: A method of performing a handoff in a mobile communication system includes measuring signal strength of signals received by a mobile station from an active base station and comparing the measured signal strength of the active base station with a first threshold value. If the measured signal strength of the active base station is less than the first threshold value, the signal strength of neighboring base stations is measured for identifying a candidate base station, which is a neighboring base station with the highest signal strength. The method also includes handing off from the active base station to the candidate base station if the measured signal strength of the active base station is less than the first threshold value and greater than a second threshold value, and if signal strength of the candidate base station is greater than the signal strength of the active base station by a predetermined value.

Abstract: An antenna matching system is used in a flip style mobile unit. The flip style mobile unit can be operated in an open status or in a closed status. The antenna matching system includes an antenna for receiving/transmitting an RF signal, a first matching circuit for operating the antenna in a first matching mode, a second matching circuit for operating the antenna in the second matching mode, and a switch for switching the antenna between the first matching mode and the second matching mode according to whether the flip style mobile unit is in the open status or in the closed status.

Abstract: A mobile phone for informing users of radiation power levels. The mobile phone includes a radio frequency (RF) circuit for providing a transmission signal, an antenna for radiating the transmission signal in radio waves, a power measuring circuit for measuring a power level of the transmission signal, an alarm processing module, and an alarming module. According to the measured result of the power measuring circuit, the alarm processing module can control the alarming module to indicate the power level of the transmission signal with image, light, sound or vibration, such that the user is aware of the radiation power level of the mobile phone.

Abstract: An apparatus and related method for matching antenna pattern to the mobile phone. The mobile phone includes an antenna, at least one radio frequency (RF) circuit and a diplexer for relaying signals of the RF circuits to the antenna. Each RF circuit has its own matching circuit, such that the antenna performance for receiving and transmitting signals can be independently adjusted without affecting each other.
