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 removable cover system for protecting solar cells from exposure to moisture during fabrication processes. The cover system includes a cover having a configuration that complements the configuration of a solar cell substrate to be processed in an apparatus where moisture is present. A resiliently deformable seal member attached to the cover is positionable with the cover to engage and seal the top surface of the substrate. In one embodiment, the cover is dimensioned and arranged so that the seal member engages the peripheral angled edges and corners of the substrate for preventing the ingress of moisture beneath the cover. An apparatus for fabricating a solar cell using the cover and associated method are also disclosed.
Abstract:
A computer peripheral device for controlling scroll bars in different windows is provided. The computer peripheral device includes a plurality of scroll bar controlling units and a signal processing unit. These scroll bar controlling units are used for generating a scroll bar controlling signal. The signal processing unit is used for analyzing the scroll bar controlling signal. According to the scroll bar controlling signal, the scroll bars in different windows are correspondingly controlled. A method for controlling scroll bars in different windows is also provided. Firstly, the signal source of the scroll bar controlling signal is analyzed. According to the signal source, the scroll bars in different windows are correspondingly controlled. Consequently, the speed of switching different windows is increased, and the working efficiency is enhanced.
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.
