Abstract: The disclosure provides a method and apparatus for extracting an avalanche signal.

Abstract: The present invention provides a system for detecting an object. The system includes a processor, a capacitive sensor operatively linked to the processor, an RF reader, and an object with an embedded RFID tag. The sensing electrode of the capacitive sensor is made from a conductive paste. The RF reader is placed below the capacitive sensor and operatively linked to the processor. And the object is placed above the capacitive sensor. The detection ranges of the capacitive sensor and the RF reader overlap in space. And once the object enters the overlapped detection space, the capacitive sensor detects the object through capacitive coupling and the RF reader detects the object through reading the RFID tag. The use of conductive paste as touch electrode in the system not only substantially eliminates the bidirectional interference resulting from both capacitive sensing and RF identification, but also is convenient and sometimes cost effective.
