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.

Communication device and digital encoding method thereof

The present invention provides a small memory device with drivers on device, which comprises a memory and a bluetooth transceiver module or a wireless transceiver module (e.g., IEEE 802.11b). In addition to common memory function, the memory can have a bluetooth drivervon device so that the bluetooth transceiver module can perform short-distance wireless transmission. The bluetooth transceiver module can thus transmit the data in the memory or receive information into the memory for storage. Besides, other common drivers can be inbuilt in the memory so that a computer system can automatically detect and install the drivers. The user needs not to take CD-ROM disks or floppy disks along with him for installation. The present invention provides a portable memory having the effects of short-distance wireless transmission, plug-and-play, and high portability.

Small memory device with drivers on device

A radio frequency (RF) signal transmitting device adapted to transmit signals between a computer and a plurality of wireless peripheral equipment is developed. The RF signal transmitting device includes a plurality of RF signal transmitters and an RF signal receiver. The RF signal transmitters are electrically connected to the plurality of wireless peripheral equipment, respectively, and each is provided for modulating an output signal therefrom into an RF signal with a specific carrier frequency and transmitting the RF signal. The RF signal receiver is electrically connected to the computer for synchronously receiving the RF signals from the RF signal transmitters and converting each of the RF signals to an operating signal to operate the computer.
