Abstract
An apparatus comprises a radio frequency (RF) signal source; and a controller configured to adjust power of the RF signal source based on a detected parameter. In one embodiment, the apparatus further comprises a proximity sensor configured to determine proximity of the RF signal source to live tissue, and the detected parameter is the proximity determined by the proximity sensor. The RF signal source may be an RF antenna. The controller may be configured to reduce the power of the RF signal source when the proximity is less than a predetermined threshold value. The controller may be configured to reduce the power to a predetermined reduced power level.
