An apparatus for adjusting a differential probe includes a regulator arranged therein capable of adjusting a distance between two tips of the probe. A first trend associated with at least a first attribute in the stream of data is identified, and based on the identified first trend, customized information is sent for presentation to the user at a mobile station. Data may be advantageously rerouted in response to the detection. FET switching is beneficial, and information can be stored either in an analog format or in a digital format.
