Embodiments of the present invention relate to a system and method for controlling a tissue treatment device using results from a spectroscopic tissue analyzer. One embodiment provides a system that uses a direct signal from a spectroscopic tissue analyzer to control the tissue treatment device. Alternatively, the system may provide an audible feedback signal to a user, allowing the user to choose how to adjust the tissue treatment device. A final embodiment provides a probe that has active sites for treating tissue, and an optical system to convey light to the active sites, allowing an analysis of the tissue parameter at the active sites.

Induced movement in a patient is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator indicating that a valid stimulation has occurred so that the operator may adjust the stimulation accordingly. A search algorithm may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector is used or, alternatively, the motion detector is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus. Other signals indicative of motor threshold may be detected and correlated to the TMS stimulus pulses. For example, left / right asymmetry changes in a narrow subset of EEG leads placed on the forehead of the patient or fast autonomic responses, such as skin conductivity, modulation of respiration, reflex responses, and the like, may be detected. The appropriate stimulation level for TMS studies are also determined using techniques other than motor cortex motor threshold methods. For example, a localized ultrasound probe may be used to determine the depth of cortical tissue at the treatment site. When considered along with neuronal excitability, the stimulation level for treatment may be determined. Alternatively, a localized impedance probe or coil and detection circuit whose Q factor changes with tissue loading may be used to detect cortical depth.

A manual control system for a vehicle includes a touch sensitive input element actuatable in response to proximity of a user's appendage. A tactile feedback generator produces a perceptible tactile stimulus. An audible feedback generator produces a perceptible audible stimulus. A sound level characterizer generates a sound characterization signal indicative of a sound-related parameter of the vehicle. A controller generates a feedback event in response to an actuation of the input element. The controller includes the perceptible tactile stimulus and the perceptible audible stimulus in the feedback event according to the sound characterization signal.

An embodiment of the present invention uses an on-board microcontroller of a household appliance to receive signals from a directionless encoder attached to a knob for receiving user input and processing the signals from the direction encoder according to a control algorithm. The microcontroller may increase the output to an electric heating element on the appliance based on a variety of criteria, including either direction of rotation, current heating element setting, or a change in directional rotation. Alternatively, or in addition, the microcontroller may provide various types of graduated visual or audible feedback to the user.
