Abstract: Provided are methods and related devices for implementing disaster recovery. According to a method, in a case where a main Session Management Function (SMF) fails, a backup SMF sends a first request to a User Plane Function (UPF), wherein the first request carries a node identifier (Node ID) of the main SMF, a Node ID of the backup SMF, and a Common Session endpoint Identifier List (CSIDLIST) corresponding to the backup SMF; and the first request is used for notifying the UPF that the main SMF fails and a session or sessions in the CSIDLIST corresponding to the backup SMF is/are to be taken over by the backup SMF, so that the UPF subsequently interacts with the backup SMF for the session or sessions in the CSIDLIST corresponding to the backup SMF.

Abstract: The disclosure provides a glitch removal circuit with low latency. The glitch removal circuit includes a first signal edge detector, a second signal edge detector, a latch, and a control signal generator. The first signal edge detector is activated according to the first control signal to detect the rising edge of the input signal to generate the first detection result. The second signal edge detector is activated according to the second control signal to detect the falling edge of the input signal to generate the second detection result. The latch sets the generated output signal according to the first detection result, and clears the generated output signal according to the second detection result. The control signal generator shields the glitch on the input signal to generate a processed signal, and generates a first control signal and a second control signal according to the processed signal.

After the filter receives an input signal, the power amplifier adjusts the power amplification, and the multi-frequency detection signal is generated with the waveform generator. The extracted signal is generated to drive the micro speaker to emit a sound signal. Afterwards, the voltage signals are extracted at two ends of the coil and the temperature signal is obtained by converting, capturing, and integrating to pass the temperature value to the external device, and the temperature value of the non-linear temperature-controlling unit is analyzed to adjust the compensation gain in real time. The smoothly control of speaker temperature and stable playback of the sound signals is played that can be achieved.

Abstract: The methods and systems presented herein provide an improved means of correcting the variation of Voltage Output Differential (VOD) in differential drivers. In some embodiments, a high-precision reference voltage is generated not only based on a desired VOD, but also by monitoring the Voltage Common Mode (VCM) in a differential driver. In some embodiments, the VOD is then compared with the high-precision reference voltage to correct the output current. The result is a low-variation output voltage.

The gate of the third transistor is coupled to ground. The gates of the first and the second transistor are coupled to a control circuit that is adapted to provide a control signal to turn the first and the second transistor on or off.
