摘要： 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.

摘要： 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.

摘要： An iterative arrangement of channel estimator (12), a Kalman filter unit (14), and a soft demodulator (16) is provided for producing an estimate of complex gain of a CDMA communications channel carrying data and pilot channels, and demodulated data of the data channel. An initial channel estimate is produced by the estimator (12) using only the low-power pilot channel. This later is improved by the iterative process using the data channel. The complex gains is represented by a sum of sinusoidal signals with different frequencies and randomly variable amplitude and phase.

摘要： Blind channel equalization methods, receivers and systems incorporating the same for use in a multiple-input, multiple-output, (MIMO) wireless communication system are described. Signal equalization is achieved by devising a characteristic system convolution matrix and algebraically operating on said convolution matrix by equalizing functions generated from second order statistics of the received signals. Such equalization is done with an aim to removing or suppressing inter-symbol interference elements from the received signals to enable satisfactory signal recovery. The described methods, systems and receivers, have the benefits of retaining the speed and processing power efficiency of equalization algorithms based on second order statistics while substantially insensitive to the accuracy of channel order estimates.

摘要： 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.

摘要： 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.
