  • Patent number: 9831902
    Abstract: Disclosed herein are a Bluetooth signal receiving device and method. The Bluetooth signal receiving device includes an energy detector circuit, a radio frequency (RF) power detector circuit, an analog-digital converter circuit, and an automatic gain control circuit. The energy detector circuit detects a significant signal, having energy higher than background noise by a threshold value or more, from a received signal. The RF power detector circuit detects the magnitude of the received signal. The analog-digital converter circuit converts the analog value of the received signal into a digital value, and outputs the digital value. When the significant signal is detected, the automatic gain control circuit determines any one of predetermined coarse gain intervals to be a first coarse gain interval of the received signal by taking into account the magnitude of the received signal detected by the RF power detection circuit.

  • Patent number: 9773644
    Abstract: A generator and method for tuning the generator are disclosed. The method includes setting the frequency of power applied by the generator to a current best frequency and sensing a characteristic of the power applied by the generator. A current best error based upon the characteristic of the power is determined, and the frequency of the power at the current best frequency is maintained for a main-time-period. The frequency of the power is then changed to a probe frequency and maintained at the probe frequency for a probe-time-period, which is less than the main-time-period. The current best frequency is set to the probe frequency if the error at the probe frequency is less than the error at the current best frequency.
