In a voice recording equipment and method, voice data from a speaker is received using a microphone. Threshold values Tand Tof surrounding environment of the voice recording equipment are determined. If an intensity of the voice data is less than or equal to the threshold value T, the voice recording is stopped and the speaker is informed that the voice data is not useful. If the intensity of the voice data is greater than the threshold values, the voice data is stored into a storage unit.

Voice recording equipment and method

In a voice-controlled navigation device and method, a voice command is received, and divided into voice segments Vi (i=1&#x2dc;n) by comparing with one or more keywords. A voice segment Vi (i=1&#x2dc;n) is obtained in sequence to be compared with tree nodes in a search tree of place names. A weight value of each tree node is computed according to a comparison, to select one or more tree nodes whose weight values are greater than a predetermined value. Routes formed by all the selected tree nodes are obtained to select a route whose total weight value is the greatest. A navigation to a destination is given by indicating the selected route on an electronic map according to place names represented by the tree nodes of the selected route.

A wireless device triggers pairing or un-pairing between the wireless device and another wireless device. The wireless device further exchanges media access control (MAC) addresses, pairing magic numbers (PMNs), and pairing indices with the another wireless device so as to establish the pairing with the another wireless device upon the condition that the wireless device triggers the pairing. The wireless device further exchanges the MAC addresses, the PMNs, and the pairing indices with the another wireless device so as to establish the unpairing with the another wireless device upon the condition that the wireless device triggers the unpairing. The pairing magic numbers are operable to identify the pairing between the wireless device and the another wireless device. The pairing indices are operable to launch the MAC addresses, the PMNs, and the pairing indices.

Wireless device, pairing method, and unpairing method

A mobile station communicates with an access point (AP). The mobile station includes a low noise amplifier (LNA) path, a power amplifier (PA) path, a switch to select the LNA path or the PA path, and a controller directing the switch. The controller estimates amplifying power of the LNA, transmitting power and a sensitivity threshold of the PA. The controller receives a current received signal strength indication (RSSI) value of the AP. The controller determines whether amplifying power of the LNA path exceeds the PA sensitivity threshold. The controller transmits a selection signal directing the switch to select the LNA path if the amplifying power of the LNA path exceeds the sensitivity threshold of the PA.
