Patent number: 8326408Abstract: A method and apparatus using brainwaves to control real objects is provided. The method and apparatus comprise using sensors to detect the brain's electrical signals and transmit at least two brainwaves to an apparatus that converts the brainwaves into a format usable by a signal processor. The signal processor determines a coherence between portions of the brainwaves, typically in the frequency domain, and compares the coherence values, which change rapidly from moment to moment, to thresholds. Based on the comparison of the coherence value to the thresholds, which are adjusted over time based on feedback relating to success, a control signal is developed that can be sent to a real object to control 3 dimensional motion of the control object.Type: GrantFiled: June 18, 2008Date of Patent: December 4, 2012Inventors: George H. Green, John LeMay

Patent number: 8326409Abstract: In a system having an interface which utilizes an electroencephalogram, device operations which are not intended by the user are reduced. An adjustment apparatus for an electroencephalogram distinction method is used for an electroencephalogram interface system. The system has a biological signal measurement section for acquiring an electroencephalogram signal from a user, and an electroencephalogram interface section for presenting via an output section a plurality of menu items of the manipulation menu in a regular order, distinguishing by a previously determined distinction method a component of an event-related potential which is contained in the electroencephalogram signal after each menu item is highlighted, and operating a device based on the distinguished event-related potential.Type: GrantFiled: February 16, 2010Date of Patent: December 4, 2012Assignee: Panasonic CorporationInventors: Shinobu Adachi, Koji Morikawa

Patent number: 8301575Abstract: This method uses two sets of sensors to estimate certain characteristics of the movement of a device or a person or states, especially postures, they adopt. A first, abundant, set of sensors (1) is removed after a learning phase where it records with certainty the states obtained by interpreting first decisional rules. The measurements of a second set of sensors (2), much more restricted than the first, are correlated to the states reached during the learning period by second decisional rules automatically obtained by supplying a classifier. They are then interpreted to determine the new states reached by the wearer just by means of the second sensors. The results are good in spite of the low number of second sensors, thanks to the accuracy of the second decisional rules.Type: GrantFiled: July 23, 2008Date of Patent: October 30, 2012Assignee: Commissariat a l'Energie AtomiqueInventors: Stephane Bonnet, Christelle Godin

Patent number: 8301257Abstract: A method for identifying, suppressing, and reversing epileptogenesis, which is considered to be a learned response due to brain plasticity. The method includes identifying three epileptogenic conditions, neuronal hyperexcitability, spatial overconnectivity, and temporal overconnectivity. A treatment that accounts for each of these conditions is then be administered to the subject to reverse, or “unlearn,” epilepsy.Type: GrantFiled: April 20, 2009Date of Patent: October 30, 2012Assignee: Wisconsin Alumni Research FoundationInventors: David Ambrose Hsu, Murielle Aline Hsu, John Matthew Beggs

Patent number: 8271076Abstract: An option which is considered to be desired by a user is determined by using an electroencephalogram interface (IF), and a determination error for the option is detected based on an electroencephalogram. If a determination error is detected, the option is corrected based on the electroencephalogram information which was used for the option determination. A correction apparatus to be incorporated in an electroencephalogram IF system is provided. The electroencephalogram IF system includes a biological signal measurement section, an analysis section for analyzing an event-related potential contained in an electroencephalogram signal of a user, an inference section for inferring an option desired by the user based on a result of analysis, and an output section for presenting the option inferred by the inference section to the user. The biological signal measurement section measures the electroencephalogram signal of the user based on a point of presenting the option to the user as a starting point.Type: GrantFiled: October 28, 2008Date of Patent: September 18, 2012Assignee: Panasonic CorporationInventors: Koji Morikawa, Shinobu Adachi
