Biosensor coated with electroactive polymer layer demonstrating bending behavior

Номер: US20120004522A1

Disclosed is a biosensor coated with an electroactive polymer layer demonstrating a bending behavior, more specifically a biosensor including an electroactive polymer layer coated on the surface of a bioreceptor and an electrode connected to the electroactive polymer layer. When an electrical stimulation is applied to the electrode, the electroactive polymer layer shows a bending behavior and thus the surface of the bioreceptor can be exposed to an analyte to allow a concentration analysis of the analyte. When used as an implantable biosensor, the disclosed biosensor may have a substantially increased life span since the bioreceptor can be selectively exposed to the analyte.

The medical data acquisition device includes a vibration source for emitting a vibration at a predetermined or random frequency. When the acquisition device is activated, a vibration is transmitted from the through the patient and is detected by the accelerometer. The accelerometer then measures the particular frequency of vibration and transmits this information to a centralized monitoring unit (CMU). Based on the measured frequency, the CMU is able to know that the same patient wearing/holding the device is also the same patient using the data acquisition device. The vibration source may revolve through a number of predetermined frequencies (as determined on its own or instructed via the CMU) or simply generate a random frequency.

If this relationship satisfies a predetermined calibration criterion, a calibration signal is triggered and is displayed, and/or automatically triggers a recalibration of the haemodynamic monitoring device. For example, the pulse contour cardiac output PCCO is derived from the arterial pressure curve as the constituent component of a 1-tuple. As long as this differs from the reference cardiac output CO Ref by less than a predefined threshold value, for example 101 or 15% of the reference cardiac output, parameter determination continues without initiating a new calibration. On the other hand, if the deviation exceeds PCCO-CO ref I, the calibration signal is triggered.

FUNCTIONAL BRAIN IMAGING FOR DETECTING AND ASSESSING DECEPTION AND CONCEALED RECOGNITION, AND COGNITIVE/EMOTIONAL RESPONSE TO INFORMATION

This invention provides method and system for measuring changes in the brain activity of an individual by functional brain imaging methods for investigative purposes, e.g., detecting and assessing whether an individual is being truthful or deceptive, and/or whether an individual has a prior knowledge of a certain face or object. The invention combines recent progress in medical brain imaging, computing and neuroscience to produce an accurate and objective method of detection of deception and concealed prior knowledge based on an automated analysis of the direct measurements of brain activity. Applying the paradigm developed from the deception model, and applying it to an individual viewing media information (e.g., audiovisual messages or movies, or announcements), the data is used to interpret the effect of the information on that individual. This permits the effective manipulation of the content of the media segments to achieve maximal desired impact in target populations or on specific individuals. 1. A computer-implemented method to objectively determine if an individual is providing a deceptive response to an inquiry , comprising:a. obtaining functional magnetic resonance image (fMRI) data of at least one cortical portion of the individual's brain in response to a test inquiry to acquire structural data reflecting at least one parameter of regional neuronal activity in the cortical portion(s) of the individual's brain, wherein the cortical portion of the individual's brain is selected from the group consisting of a left lateral prefrontal cortex, anterior cingulated cortex, orbitofrontal cortex, premotor cortex, parietal cortex, left medial frontal gyri, right medial frontal gyri, bilateral superior frontal gyri, and left orbital gyri, wherein the parameter(s) optionally is(are) increased cerebral blood flow and/or a change in proportion of oxygenated hemoglobin associated with increased metabolic activity of brain cells within such portion(s) of the individual' ...

A reflection-detector sensor position indicator comprises emitters that transmit light having a plurality of wavelengths. A detector outputs a sensor signal. At least one reflection detector outputs at least one sensor position signal. An attachment assembly attaches the emitters, the detector and the reflection detector onto a tissue site. A sensor-on condition indicates that the attachment assembly has positioned the emitters generally centered over a fingernail, the detector on a fingertip opposite the fingernail and the reflection detector over the fingernail. The sensor signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after attenuation by pulsatile blood flow perfused within a fingernail bed underneath the fingernail. The sensor position signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after reflection off of the fingernail. 1. An optical sensor configured to provide an indication of a physiological parameter comprising:a plurality of emitters that transmit light having a plurality of wavelengths;a detector that outputs a sensor signal, the sensor signal is at least substantially responsive to the emitter transmitted light after attenuation by pulsatile blood flow perfused within a fingernail bed underneath the fingernail; andat least one reflection detector that outputs at least one sensor position signal, the sensor position signal including a sensor-on condition indicating that the attachment assembly has positioned the emitters generally centered over a fingernail, the detector on a fingertip opposite the fingernail and the at least one reflection detector over the fingernail, the at least one sensor position signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after reflection off of the fingernail.an attachment assembly that attaches the emitters, the detector and the at least one reflection ...

An implantable medical device comprising a coronary perfusion measurement unit is adapted to measure and determine parameters related to coronary perfusion of heart tissue. The parameters include time periods and perfusion magnitudes. The coronary perfusion measurement unit is configured to determine a time period T related to a perfusion event of a coronary vessel and including includes a reperfusion time period, where a perfusion event is defined as a decrease of coronary perfusion followed by reperfusion, and to generate a time period signal in dependence thereto. The implantable medical device further comprises a coronary flow calculation unit that is adapted to receive the time period signal and that is adapted to process the time period and to generate an ischemia risk indicating index I in dependence of the time period. 1.
