The invention relates to substituted aminoindanes and analogs thereof of formula and the pharmaceutical use thereof. The cell cancellation method includes detecting interference from a cell. Preferred transport factors include the protective antigen binding domain of lethal factor from B. The wireless device may instruct the wireless smart card reader to enter the low-power state by sending a deactivation alert if the wireless device identifies that communication of data between the wireless device and the wireless smart card reader is not likely to occur within a specified period of time. The at least one feedback device provides feedback for at least one of: positioning a distal end of an ablation catheter in a desired position in the esophagus adjacent a target area of the cardiac tissue to be ablated, forming an adequate lesion, and assessing lesion formation.
