Assignee:

Capita Systems, Inc. - King of Prussia PA

International Classification:

A61B 50478

US Classification:

600383

Abstract:

A headset and system for taking EEG measurements on the head of a test subject. The headset has a plurality of electrode sensors in predetermined anatomical positions on the head of a subject to take EEG measurements, for example of the subject's response to certain stimuli. The electrode sensors are formed of dry conductive foam rubber pads attached to conductor elements. An individual shielded cable is attached to each sensor to carry the detected signal to a signal processor. The sensors may be formed of a carbon impregnated foam rubber pad that offers high conductivity. The sensors do not require wetting agent, and thus can be used in a very time efficient manner, and can be easily replaced for sanitary considerations.

International Classification:

A61B 504

US Classification:

600544

Abstract:

A system to integrate and synchronize a plurality of signals for recording on a destination video recording device and/or for display on a monitor. The plurality of signals represent the response of a respective of a plurality of test subjects to certain stimuli. A plurality of test subjects view an audio-visual display from an audio-video source, such as a video cassette recorder, while respective EEG responses to the audio-video display are measured. The respective EEG responses are sent to respective processors and converted to graphical representations of the EEG signals. The graphical representations of the EEG signals and a signal from the source audio-video device are sent to respective destination VCRs and/or a respective destination audio-video recording device that records the data from both sources. The respective destination audio-video recording devices can send respective composite signals to a respective destination VCR and/or a respective destination monitor to record and/or display the synchronized signals from the source audio-video recording device and the graphical representation of the EEG signals simultaneously. The respective destination VCRs and respective destination monitors can also record and/or display output and control data such as the time and date of the test.

International Classification:

A61B 310

US Classification:

351200

Abstract:

Apparatus and method are provided for assessing the direction of fixation of an eye by detecting polarization-related changes in light retroreflected from the fundus of the eye. Nerve fibers in the retina of the eye are birefringent and alter the polarization state of light traversing them as a function of their orientation. The nerve fibers are arrayed in a characteristic pattern in the retina, specifically radiating outward from the fovea and converging to the optic nerve head. By assessment of polarization-related changes in rctroreflected light from multiple retinal areas either sequentially or simultaneously, characteristic birefringence signatures of portions of the retina can be identified which are used to assess the direction of fixation of the eye. In addition, interference from the corneal birefringence is reduced by using incident light having a polarization state that is substantially independent of meridional direction. Circularly polarized light or non-polarized light is used for the assessment.

Abstract:

A magnetic-resonance-imaging-compatible (MRI-compatible) cardiac defibrillator includes: a defibrillator generator; first and second electric wires, each being electrically connected to said defibrillator generator; first and second defibrillation pads, each being electrically connected to a respective one of said first and second electric wires; and a low pass filter electrically connected between said defibrillator generator and said first and second electric wires to prevent a noise in an MRI image caused by a radiofrequency interference from the defibrillator as well as protect a patient and the defibrillator from MRI radiofrequency imaging signals, wherein said low pass filter has a cutoff frequency set such that differential mode noise at an MRI Larmor frequency is in an attenuated band while a system-test signal by said defibrillator generator is in a pass band of said low pass filter.
