Title: Method and apparatus for translating the eeg into music to induce and control various psychological and physiological states and to control a musical instrument
Inventor: KNISPEL JOEL
IPC: A61B5/375
Filed: 1988-08-18
Granted: 1993-09-07
Abstract: ABSTRACT          A method and apparatus for applying a musical feedback signal to the human brain, or any other brain, to induce controllable psychological and physiological responses.  A signal representing the ongoing electroencephalographic (EEG) signal of a brain preferably is obtained from the electrode location on the scalp known as CZ or P3 in clinical notation.  A signal processor converts the ongoing EEG into electrical signals which are converted into music by synthesizers.  The music is acoustically fed back to the brain after a time delay calculated to shift the phase of the feedback in order to reinforce specific or desired ongoing EEG activity from the scalp position of interest.  The music is comprised of at least one voice that follows the moment-by-moment contour of the EEG in real time to reinforce the desire EEG activity. The music drives the brain into resonance with the music to provide a closed loop or physiological feedback effect. Preferably, the musical feedback comprises additional voices that embody psychoacoustic principles as well as provide the content and direction normally supplied by the therapist in conventional biofeedback.  The invention contemplates numerous applications for the results obtained.

Title: Unitary disposable chair, formable from fiberboard in one machine pass with minimal waste, and very quickly set up
Inventor: VOLPE JAMES R
IPC: A47C4/00
Filed: 1988-12-02
Granted: 1992-02-11
Abstract: UNITARY DISPOSABLE CHAIR, FORMABLE FROM FIBERBOARD IN ONE      MACHINE PASS WITH MINIMAL WASTE, AND VERY QUICKLY SET UP     ABSTRACT OF THE DISCLOSURE     This chair folds flat for storage and shipment, or unfolds and configures for use, in only a few (e. g., three to five) seconds.  Even though it is very strong and stable, the chair can be made from one very simple blank of five rectangular panels, two smaller auxiliary panels and a glue tab, using only two glue joints.  Its lower portion is a rectangular glued tube with a vertical seat-support panel across the inside, parallel to two of the outer walls of the tube -- so that the support panel, though preglued in place, folds and unfolds with the tube.  The upper part of the chair is an extension of the tube, but the front panel folds inward, backward, and downward to form a seat that spans the tube, supported by the front panel and by the seat-support panel.  The upper part of each side also folds inward and downward, but only above a diagonal fold line running from the upper rear corner of the chair downward and forward to meet the fold line of the front-and-seat panel.  The sides double over along this diagonal fold; hence the seat is in effect hung from the diagonal top folds, and receives some slight additional support in this way.  The back is also scored to allow deformation of the tube in a buckling mode, for added comfort of the occupant.

Abstract: SCATTERED TOTAL INTERNAL REFLECTANCE IMMUNOASSAY SYSTEM            Abstract of the Disclosure A new immunoassay system is provided for the detection of ligands or ligand binding partners in solution in a heterogeneous format.  The invention relies upon the detection of back scattered light from an evanescent wave disturbed by the presence of a colloidal gold label brought to the interface by an immunological reaction. The evanescent wave existing at the interface in turn is the result of a totally internally reflected incident light wave.  Placement of the detector at a back angle above the critical angle insures a superior signal-to-noise ratio.

IPC: H04H60/13
Filed: 1992-08-13
Abstract: For so-called ''variable dynamics'', a time-variant control signal is transmitted in exact time-correlated association with the radio programme signal. The control signal contains an information concerning the varying modulation of the original radio programme signal and is used in the receiver during the repetition of the radio programme signal to make the broadcasting studio modulation at least partially reversible in the sense of a variable dynamic. According to the invention, the broadcasting studio incorporates the time-variant control signal in the data stream of a radio data signal (RDS) in a manner appropriate to the data format. The RDS signal supplemented in this manner is transmitted from the broadcasting studio to terrestrial transmitters. In each transmitter, the respective supplemented RDS signal received is modulated to an auxiliary carrier, incorporated in the modulated time-correlated radio programme signal present in the form of a time-correlated multiplex signal, and broadcast terrestrially together with the multiplex signal. In the receiver, the multiplex signal received is retrieved from the RDS signal. The varying control signal is separated from the data stream of the RDS signal and used to control the dynamics (difference in level between the softest and loudest tones) of the retrieved useful signal component of the multiplex signal. Radio transmitters and receivers.
