A transition minimized differential signaling (TMDS) receiver system including a clock channel, a plurality of data channels, a TMDS decoding unit, and a self-test unit is provided. The clock channel receives, processes and outputs a clock signal. Each data channel receives, processes and outputs a corresponding data signal according to the clock signal. The TMDS decoding unit receives and decodes the processed data signals. The self-test unit receives the clock signal and an external parallel signal, and accordingly, generates a test signal for performing the BIST on the data channels and the TMDS decoding unit. A BIST method adapted for the TMDS receiver system is also provided.

An interference-resistant method for a wireless audio system capable of transforming an audio signal into an RF signal includes transforming the audio signal into a PCM signal, appending a first control signal to the PCM signal, and modulating the PCM signal with the first control signal into an analog base-band signal. The method further includes up-converting the analog base-band signal into the RF signal and transmitting the RF signal into the air in a transmitting mode and receiving the RF signal in the air during a receiving mode. The channel is switched to another one upon determining that a Received Signal Strength Indicator (RSSI) level of the RF signal is greater than a first predetermined value a plurality of times within a predetermined time interval.

A carrier recovery circuit of receiving an OFDM data, comprising a demodulator, a domain transformer, an equalizer, a frequency offset detector, and a compensator. The demodulator demodulates the OFDM data with a carrier signal. The domain transformer is coupled to the demodulator, and transforms the OFDM data to frequency domain. The equalizer is coupled to the domain transformer and frequency equalizes the OFDM data. The frequency offset detector is coupled to the equalizer, retrieves a phase reference data from the OFDM data, and determines a frequency offset based on the phase reference data and a predetermined data in the carrier recovery circuit. The compensator is coupled to the frequency offset detector, and compensates the frequency offset signal based on the estimated frequency offset.

An apparatus (101) for peeling release films (142) used in the manufacturing of liquid crystal display devices includes a winding mechanism for winding a pair of tapes (130) to peel a release film off from a polarization plate (141), a release film peeling mechanism, and a detecting means (120) having a mount (122) and several detectors (121). The detectors are installed on the mount for detecting any deviation of the tape. When a deviation occurs, the relevant detector sends a signal to a control unit (150). The control unit then sends out a signal to a power supply (160) of the apparatus to turn off the apparatus. The control unit also sends out a signal to an alarm device, so as to alert relevant personnel of the occurrence of the deviation.
