The present invention provides systems and methods for selectively applying electrical energy to a target location within the head and neck of a patient’s body, particularly including tissue in the ear, nose and throat. In one embodiment, the present invention allows a proxy to be placed into an NTLM or HTLMv2 environment and have it transparently ensure that NTLM transactions are handled appropriately, such that the proxy can interact with the authenticated content without breaking the authentication scheme. The rationality diagnostic device corrects the output value of the remaining fuel amount sensor in accordance with the output value of the alcohol concentration sensor to eliminate an alcohol-concentration-dependent component from the output value of the remaining fuel amount sensor. As used herein, a page or site that has such an association is sometimes referred to as \u201csubject-specific.
