Systems and methods for displaying changes in biological responses to therapy
InactiveUS7720306B2Better convey information to the viewerImprove visibilityDrawing from basic elementsPerson identificationCorrelation functionDisplay device
Systems and methods of this invention display data using pixels with information indicated by color and intensity changes, particularly used for monitoring of physiological variables in real time. For certain methods, physiological data can be acquired by sensors, acquired data can be stored in data frames, data frames can be processed using computer-implemented methods, and processed data frames can be scaled to a display frame for display on a display device. Using such methods, a spot made up of a group of pixels can be updated during a time frame, or cycle using a computer-implemented method, such as addition, subtraction, multiplication, division or a time dependent function. Newly received data can be combined with prior received data to indicate time-dependent changes. In this way, each spot contains a cumulative history of data starting at some initial time. In other embodiments, visual contrast can be enhanced between desired data and other data. In further embodiments, two or more different types of data can be plotted together to indicate relationships between variables. Real time monitoring of signals during therapeutic treatment using light, electricity or other nerve or muscle stimuli can allow a user to monitor physiological responses during stimulation and to make rapid decisions about medical treatment.

Indirect measurement of tissue analytes through tissue properties
InactiveUS20040127777A1Improve accuracy and precisionLimited stateDiagnostics using spectroscopyRaman scatteringAnalyteMedicine
Methods and system for noninvasive determination of tissue analytes utilize tissue properties as reflected in key features of an analytical signal to improve measurement accuracy and precision. Physiological conditions such as changes in water distribution among tissue compartments lead to complex alterations in the measured analytical signal of skin, leading to a biased noninvasive analyte measurement. Changes in the tissue properties are detected by identifying key features in the analytical signal responsive to physiological variations. Conditions not conducive to the noninvasive measurement are detected. Noninvasive measurements that are biased by physiological changes in tissue are compensated. In an alternate embodiment, the analyte is measured indirectly based on natural physiological response of tissue to changes in analyte concentration. A system capable of such measurements is provided.

Method and system for using coherence of biological responses as a measure of performance of a media
ActiveUS20080222670A1Strong correlationImprove fluencyElectroencephalographyAnalogue secracy/subscription systemsComputer scienceEmotionality
Various embodiments of the present invention create a novel system for rating an event in a media based on the strength of the emotions viewers feel towards the event. The viewer's responses to the media can be measured and calculated via physiological sensors. The metric for rating the strength of the media is created based on the mathematical coherence of change (up or down) of all pertinent physiological responses across multiple viewers. Such rating offers an objective ability to compare the strengths of events of the media, as there is a strong correlation between high coherence of physiological responses (all viewers feel the same thing at the same time) and strong ratings of emotionality, engagement, likeability, success in the marketplace / on screen.

Systems and methods for therapeutically treating neuro-psychiatric disorders and other illnesses
Systems and methods for treating neuro-psychiatric disorders, such as depression or schizophrenia, and / or other illnesses are disclosed. A patient is diagnosed with a particular neuro-psychiatric disorder or other illness. An electric nerve stimulation (ENS) technique, such as vagus nerve stimulation (VNS), is administered to the patient in conjunction with a magnetic nerve stimulation (MNS) technique. The magnetic nerve stimulation (MNS) technique includes applying a magnetic field to a pre-selected synaptic region of a brain of the patient based on the diagnosis. A physiological response of the brain, such as electroencephalogram (EEG) activity, is monitored. One or more parameters of the magnetic field may be selectively adapted in response to the monitored physiological response. The administration of the ENS technique and the MNS technique may be performed simultaneously, in serial order, or in alternating order depending on the diagnosis.

InactiveUS20080295126A1Accurate measurementAnalogue secracy/subscription systemsBroadcast information monitoringComputer sciencePhysiological responses
A novel approach enables comparing and aggregating physiological responses from viewers to a time-variant media. This approach defines key events in the media, measures physiological response to and timing of each of the key events for each viewer of the media, aggregates such response for each key event, reconnects these events in the order they occur, and creates a “profile” of the piece of media. This profile can then be used to accurately gauge the responses from the viewers as when the viewers are engaged in the media and when they are not engaged. Subsequently, such profile can be used to define what needs to be changed in the media to generate the desired responses from the viewers.
