Abstract:
A synchronous wireless transmission method is used in a synchronous wireless transmission system including a first wireless device for generating a wireless signal, a second wireless device for generating a second wireless signal, and a wireless signal receiver for receiving the first and second wireless signals. The wireless signal receiver receives the first wireless signal in the first receipt time segment and the second wireless signal in the second receipt time segment. When the first or second wireless signal is received, the wireless signal receiver issues a responding signal to the first or second wireless device. According to the responding signal, the first and second wireless device determines whether the time of issuing the first or second wireless signal to the wireless signal receiver is adjusted.
Abstract:
The present invention relates to a method for testing and pairing a wireless peripheral device. Different communication channels and different identification codes are used for testing and pairing the wireless peripheral device. As a result, the erroneous pairing relation the wireless input device and the wireless transceiver of the wireless peripheral device is avoided.
Abstract:
The present invention provides a channel switching method for use with a wireless mouse by intelligently switching the communication channels with a wireless signal receiver. Firstly, the packet error rate is detected to discriminate whether the number of continuous failed packets is greater than a threshold value. Subsequently, the received signal strength indicator (RSSI) is detected to discriminate whether the wireless transmitter needs to switch the current communication channel with the wireless signal receiver.
Abstract:
A wireless transmission method is provided for allowing data transmission between plural wireless devices. In the wireless transmission method, each time cycle is divided into a flag time segment and a transmission time segment. The flag time segment includes plural flag time slots corresponding to respective wireless devices, and the transmission time segment includes plural transmission time slots. After the plural wireless devices are synchronized with each other, the wireless device for transmitting data issues a transmission request during the corresponding flag time slot. In response to the transmission request, a corresponding wireless device issues an assigning command during the corresponding flag time slot. The wireless device issuing the transmission request will transmit data during a transmission time slot assigned by the assigning command. In accordance with the wireless transmission method, each of the plural wireless devices has transmitting and receiving capability.

Abstract:
An optical disc drive and tracking method thereof are disclosed. The optical disc drive includes an optical pickup head, a slip compensation module, a tracking control module and a tracking drive. The optical pickup head generates a detected signal according to an optical signal from an optical disc. The slip compensation module generates a slip compensation signal according to the detected signal. The tracking control module generates a tracking out signal according to the detected signal and the slip compensation signal and, according to the tracking out signal, the tracking drive drives the optical pickup head.
Abstract:
An automatic frequency hopping method is provided for use with a wireless device. The wireless device could transmit data in two or more communication frequency bands. According to the counts of successful data transmission in respective communication frequency bands, the reasons of communication failure are analyzed. According to the reasons of communication failure, the automatic frequency hopping method discriminates whether a frequency hopping procedure is performed. Since the frequency hopping procedure is performed when a proper frequency hopping condition is satisfied, the automatic frequency hopping method could achieve the power-saving purpose and avoid the wireless communication interference with other wireless devices.
