Abstract
Systems and methods for detecting concussions in real-time are provided. An exemplary system of detecting concussions in real time includes an accelerometer to measure acceleration event and generate an accelerometry signal. The system includes a plurality of electrodes to detect an electroencephalogram (EEG) and each of the electrodes can be attached to a top region of the headgear through a flexible shaft. The system further includes a signal processing circuit to amplify, filter and broadcast an electroencephalogram (EEG) signal to a local wireless receiving unit.
Claims24
A system for detecting concussions suffered by a user in real-time, comprising:
- a protective headgear configured to be worn by the user;
- an accelerometer, adapted to be coupled to the headgear, and configured to measure an acceleration event and generate an accelerometry signal;
- a plurality of electrodes, each adapted for attachment to the headgear;
- and
- a signal processing circuit, adapted to be coupled to the headgear, and configured to:
- amplify an electroencephalogram (EEG) signal detected by at least one of the plurality of electrodes indicating a concussion suffered by the user;
- filter noise from the EEG signal;
- and
- broadcast the EEG signal to a local wireless receiving unit, wherein the EEG signal is detected in an earliest period of time after the acceleration event has occurred, wherein the earliest period of time occurs when the accelerometry signal is first able to fall below a predetermined threshold.
A method for detecting concussions in real-time using a detection system, coupled to a pad, including an accelerometer and a plurality of electrodes, comprising:
- measuring an acceleration event using the accelerometer;
- generating an accelerometry signal;
- detecting an electroencephalogram (EEG) signal using the plurality of electrodes;
- amplifying the EEG signal in the detection system;
- filtering noise from the EEG signal;
- and
- broadcasting the EEG signal to a local wireless receiving unit, wherein the EEG signal is detected in an earliest period of time after the acceleration event has occurred, wherein the earliest period of time occurs when the accelerometry signal is first able to fall below a predetermined threshold.
A padding system for detecting concussions in real-time, comprising:
- an accelerometer, coupled to a pad, and configured to measure an acceleration event and generate an accelerometry signal;
- a plurality of electrodes, each of the plurality of electrodes are coupled to the pad;
- and
- a signal processing circuit, coupled to the pad, and configured to:
- amplify an electroencephalogram (EEG) signal detected by at least one of the plurality of electrodes indicating a concussion suffered by a user;
- filter noise from the EEG signal;
- and
- broadcast the EEG signal to a local wireless receiving unit, wherein the EEG signal is detected in an earliest period of time after the acceleration event has occurred, wherein the earliest period of time occurs when the accelerometry signal is first able to fall below a predetermined threshold.
