An integrated circuit device may have an internal oscillator for generating a system clock, a trimming logic with a trimming register for adjusting an oscillation frequency of the internal oscillator; a serial data receiver, wherein a serial data stream includes a synchronization signal. The invention provides methods and systems for switching and routing of multicast data packets in two stages. The digital signal processing mechanism is to generate inverse analog encoder signals from the different analog encoder signals, and to apply dynamically changeable gain and offset corrections in real-time. A rotating disk is located at the bottom of the accommodating space in the container body for holding and turning the low-level radioactive waste to be treated and also facilitating the worker to pass through the non-barrier hollow channel for cleaning task. Additionally, a capacitor is connected to the secondary coil of the transformer to form a bandpass filter, thereby attenuating a harmonic signal included in the oscillating signal.
