    Abstract: A performance evaluation system for a multiple-input multiple-output (MIMO) antenna system receives simulation parameters from an input device, and simulates a MIMO antenna system accordingly. A method, also provided, further evaluates performance of the simulated MIMO antenna system when a series of radio frequency (RF) signals are transmitted through the MIMO antenna system, and displays a performance analysis result of the MIMO antenna system on a display device for evaluation of the performance of the simulated MIMO antenna system.

    Abstract: A scanner includes a first illuminant device having a first power associated therewith, and a second illuminant device having a second power associated therewith. The first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document. The scanner is configured to select one of the first illuminant device and the second illuminant device based, at least in part on, a level of power supplied to the scanner via a power source, and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.

    Abstract: A recording method for an optical disk drive is implemented as follows. First, at least one of the level of the focusing error signal, the level of the tracking error signal, a wobble synchronization pattern loss, the error rate of demodulating a wobble signal, the frequency of buffer under-run occurrence, the temperature of the drive, the wobble jitter and the level of write power is detected. If at least one detected value exceeds the preset value, the recording will be ceased. Then, the rotation speed of the optical disk drive is decreased, and the recording is resumed with the decreased rotation speed. If at least one of the temperature of the drive, the wobble jitter and the estimated write power exceeds the reset value before recording starts, the rotation speed of the optical disk drive is decreased before recording.

    Abstract: A timing calibration circuit for a time-interleaved analog-to-digital converter (ADC) is provided. The timing calibration circuit includes a correlation unit, an adaptive filter and a delay cell. The correlation unit generates a first correlation coefficient according to a first zero-crossing possibility distribution between a first digital data and a second digital data, and generates a second correlation coefficient according to a second zero-crossing possibility distribution between the second digital data and a third digital data. The adaptive filter generates a predicted time skew according to a difference between the first correlation coefficient and the second correlation coefficient. The delay cell calibrates a clock signal of the ADC according to the predicted time skew.

    Abstract: In a method for checking layout of a printed circuit board (PCB) using an electronic device, a power line is selected from a layout diagram of the PCB. The method searches for one or more signal lines which are overlapping with the selected power line from the layout diagram of the PCB. The method further locates attribute data of the searched signal lines and the selected power line in the layout diagram of the PCB, and displays the attribute data of the searched signal lines and the selected power line on a display device of the electronic device.
