Abstract: An antenna device includes a supporting body and an antenna. The supporting body has two arms and a connecting portion disposed between and connecting the two arms. The antenna has a grounding portion extending from one end of one of the arms. A free end of the grounding portion perpendicularly extends toward the other arm to form a first radiating strip, and a second radiating strip, a third radiating strip and a fourth radiating strip are respectively integrally formed in turn. The first, second, third and fourth radiating strips together define substantially a rectangular shape. A feed-in portion extends from the first radiating strip. The grounding portion connects the supporting body functioning as a ground of the antenna, which increases the area of the grounding for the antenna and enhances the performance of signal transmitting and receiving of the antenna device.

Abstract: A wireless network device with data storage is provided that utilizes a wireless connection to communicate with a LAN. The wireless network device with data storage includes a control unit, a memory element and a wireless communication module. The control unit includes a base-band processor, an RF interface, an external memory interface and a host device interface, wherein the base-band processor is adapted to process all data input/output through each interfaces. The RF interface connects the wireless communication module with the control unit, the external memory interface connects the memory element with the control unit, and the host device interface makes the control unit connect with an electronic device. The wireless communication module is able to either transmit or receive wireless signals from other electronic devices. The memory element is divided into two storage areas, one used for storage of the driver program for the control unit, the other for storage of user data.

Abstract: An echo cancellation method in a wireless headset communication system includes the steps: (1) providing at least one delayer and at least one amplifier for respectively performing a specific phase modulation and a specific amplitude adjustment on at least one branch signal of a receiving signal received from a far-end user, thereby generating at least one pseudo echo signal having identical phase and amplitude with those of at least one actual echo signal; (2) performing at least one signal-mixture process on the pseudo echo signal and a sending signal in which the actual echo signal is contained to subtract the pseudo echo signal from the sending signal, thereby counteracting the actual echo signal. The present invention can provide a better echo cancellation effect, and simultaneously has an advantage in the easiness for bring into practice and low practice cost.

Abstract: The present invention provides a communication device and a digital encoding method thereof. The communication device comprises a first and a second emitting devices respectively communicating at a first and a second communication channels. Each emitting device emits the same piece of data through continually emitting the same signal section for six times. The signal section is encoded in five bits. A receiving device alternately jumps between the first and second communication channels to receive signal sections emitted by the first and second emitting devices. The time of the receiving device at each communication channel comprises a phase lock time and a reception time of a whole signal section. The present invention has the advantages of having a very good quality of data transmission, reducing the cost, saving installation space, and facilitating the operation.
