Abstract: In a voice recording equipment and method, voice data from a speaker is received using a microphone. Threshold values T1 and T2 of 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 T2, 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.

Abstract: In a voice-controlled navigation device and method, a voice command is received, and divided into voice segments Vi (i=1˜n) by comparing with one or more keywords. A voice segment Vi (i=1˜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.

Abstract: 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.

Abstract: 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.

Abstract: A system time setting function for an electronic device includes a battery module, a clock module, a processing module and a storage module. The battery module includes a battery gauge integrated chip which times in cycles and measuring a remaining battery capacity. The clock module generates a system time T0 when the electronic device is powered on. The processing module obtains and stores an oscillation time T1 and a remaining battery capacity C1 from the gauge integrated chip. The processing module further obtains a current oscillation time T2 and a currently measured remaining battery capacity C2 and calculates the period for which the electronic device has been powered off and further determines the current system Te according to that length of time, the stored system time T0, the current remaining battery capacity C2 and the stored remaining battery capacity C1.

Abstract: A system and method of deploying a master key for a first communication device and second communication device. The first communication device receives a request message from the second communication device through a wireless communication network, and creates a master key algorithm based on configuration parameters of the request message. The first communication device further generates a master key according to the master key algorithm, verifies whether the master key created by the first communication device is correct, and installs the master key in the first and second communication devices when the master key is correct.

Abstract: A wireless device (100) for exchanging keys with another wireless device (200) includes a key request module (121), a key generation module (122), and a key transfer module (123). The key request module requests to exchange a key by transmitting a request-key-change frame to the another wireless device. The key generation module generates a new key when the key exchange request is successful. The key transfer module encrypts the new key with a public key of the another wireless device, and transmits a new-key-send frame with the encrypted new key to the another wireless device. A key exchange method is also provided.
