Abstract: An open ear canal hearing aid system comprises an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. The open ear canal hearing aid system further comprises a sound processor for amplifying received ambient sounds included within a predetermined frequency to produce processed sounds and for supplying said processed sounds to said ear canal tube.

Abstract: A method for spectral signature interpretation. The method includes the creation of a mathematical model of a system or process. A neural network training set is then developed based upon the mathematical model. The neural network training set is developed by using the mathematical model to generate measurable phenomena of the system or process based upon model input parameter that correspond to the physical condition of the system or process. The neural network training set is then used to adjust internal parameters of a neural network. The physical condition of an actual system or process represented by the mathematical model is then monitored by extracting spectral features from measured spectra of the actual process or system. The spectral features are then input into said neural network to determine the physical condition of the system or process represented by the mathematical. More specifically, the neural network correlates the spectral features (i.e.

Abstract: A magnetic suspension system and a procedure for operating the system employ a superconducting magnet having a lift coil assembly for developing a magnetic field to interact with the magnetic field of an object to be supported about the superconducting magnet. Smaller and larger magnet coils are provided in the superconducting magnet with counter rotating flow of current to introduce a depression in a potential energy surface above the superconducting magnet, this allowing the object to seek a height at the depression for stably locating the object. The system and methodology employs a set of control coils which are energized to orient and to translate the object to maintain a desired position and orientation. Pairs of the control coils are energized to produce a tilting of the object, as in roll or pitch, or a displacement of the object relative to the vertical axis.
