Filed:

Jul 11, 2005

Appl. No.:

11/178714

Inventors:

Joseph Colombo - Richboro PA, US
Robert G. Welch - Media PA, US
Benhur Aysin - Bensalem PA, US

Assignee:

Ansar, Inc. - Philadelphia PA

International Classification:

A61B 5/0402

US Classification:

600513

Abstract:

The present invention is a method and apparatus for non-invasive, real-time monitoring of the autonomic nervous systems. The present invention allows for monitoring of the autonomic nervous system using spectral analysis of both heart rate and respiratory signals. A preferred embodiment uses short-time Fourier transform (STFT) with a novel modified Bartlett windowing scheme in real-time so that the dynamic interactions between the sympathetic and parasympathetic divisions of the autonomic nervous system can be independently monitored. In addition, a preferred embodiment of the present invention uses the same techniques to monitor other biological or physiological data, including continuous blood pressure.

Abstract:

The invention presents a method for deriving respiratory data from single lead ECG recordings for monitoring the autonomic nervous system, specifically the parasympathetic and sympathetic nervous systems independently and simultaneously. The ECG derived respiration for ANS monitoring devices generally includes a method for non-invasive monitoring of the respiratory activity for the assessment of the parasympathetic and sympathetic (P&S) branches of the autonomic nervous system. The EDR signal is used to analyze and assess the individual activities of, and interactions between the sympathetic and parasympathetic divisions of the ANS. The present invention applies a QRS peak detection algorithm to ECG signal. The peak amplitudes and respective time locations are then used to generate the respiration signal. The EDR provides an approximate but reliable estimate of the respiratory activity. The utility of the algorithm is tested for the P&S monitoring for the various tasks such as Normal Breathing (Baseline), Deep Breathing, Valsalva Maneuvers, and Standing, as well as for normal subjects, and ill and geriatric patients.

Assignee:

Veda Incorporated - Warminster PA

International Classification:

G09B 908

US Classification:

364578

Abstract:

A process for controlling a gimballed motion base system substantially duplicating pilot perceptions in a simulated aircraft. The process includes: a subprocess accounting for an effect of yaw on a motion base arm, a full-G bias function and a limited-G bias function, a low-G bias function, improved computation of pitch and roll gimbal commands to negate artifacts, a negative-G algorithm, allowing various yaw gimbal positions, allowing various cockpit orientations, and a yaw gimbal control process. A perceptual model based on emperically observed human response data predicts perceived pitch, roll, and yaw, and accounts for the fact that a Gy component of linear acceleration affects both roll and yaw perception.

A process for controlling a gimballed motion base system substantially duplicating operator perceptions in a simulated vehicle. Such vehicles may include but not be limited to, aircraft, automobiles, boats, roller coasters, bob sleds, and futuristic space vehicles.

Abstract:

A arterial blood velocity-to-volume flow rate converter, including a pair of function generators a computer, and a multiplier, is incorporated within a system to objectively measure by non-invasive means the blood volume flow rate to the head of an occupant in a rapidly accelerating vehicle, and take corrective measures to stabilize the vehicle when that flow falls below a preselected lower limit for a predetermined length of time. A conventional ultrasonic Doppler velocimeter determines the blood velocity, subsequently feeding a representative signal to pressure function generator. The output therefrom is then fed to a cross-sectional area signal generator which determines the time-varying area of the artery, a signal representing such being fed to the multiplier along with the velocity signal to compute the flow. When that flow falls below a pre-selected lower limit for a predetermined length of time as determined by a comparator and timer, a command signal is sent to override circuitry to stablize the vehicle.
