Abstract
A protective headgear system includes protective headgear worn upon a head of a first user, a sensor physically coupled to the protective headgear, an audio device and a controller. The sensor measures an angular position of the protective headgear and detects an impact involving the protective headgear. The audio device selectively emits a sound based on the angular position of the protective headgear. The controller generates impact information by analyzing the impact and determining a susceptibility of the first user to a concussion.
Description
- This application claims the benefit of U.S. Provisional Application No. 62/717,188, which was filed on Aug. 10, 2018 and titled “Protective Headgear System”. The entire content of this application is incorporated herein by reference.
- The present invention relates to the field of Head Impact Telemetry (HIT). More specifically, the present invention addresses concussions sustained by individuals, particularly children and youth who play contact sports during the most critical years of their development.
- Playing sports is considered to be one of the most common causes of concussions, particularly among younger children (ages 8 and younger) who are still growing, less coordinated and have slower reaction times than adults. Varying maturity rates (resulting in differences in height and weight) amongst children playing together increases the risk of injury.
- Concussions, defined as the temporary loss of normal brain function resulting from an internal head injury, can cause permanent brain damage with repeated occurrences. Determining or understanding the seriousness of an injury is difficult. Some internal head injuries can be serious and potentially life-threatening, causing torn blood vessels, a broken skull bone or even damage to the brain itself.
- U.S. Patent Application Publication No. 2015/0216247 discloses impact-reducing protective headgear that includes magnetic material configured to reduce the impact of a collision to the head of a wearer. A similar system is disclosed in U.S. Pat. No. 8,860,570, which is directed to a portable, wireless, personal-head-impact reporting system comprising a mobile communication device capable of sensing, analyzing and reporting a collection event experienced by a person. U.S. Pat. No. 9,032,558 discloses a helmet system that protects a user from sustaining concussions and other head injuries. These patent documents are incorporated herein by reference.
- The present invention employs an accelerometer device, embedded in headgear, that can detect impact due to force and change in elevation, monitoring, measuring and assessing the wearer's susceptibility to a concussion should they receive a blow to the head. Depending on the impact, a message is automatically sent to an application on a parent's mobile device or tablet.
- Specifically, in the present invention, an accelerometer is embedded in a sports helmet equipped with motion sensors, a processor and a transmitter. The device can be used for both training and official gameplay utilizing Adafruit IO™. In the training scenario, should a child position his head at an angle deemed unsafe, a bell or beep will sound inside the helmet, reminding him to raise his head. Over time, the goal is that he will instinctively begin to recognize appropriate and proper positioning techniques and engage in safe contact.
- During an actual game, the accelerometer measures the G-force, or magnitude of impact, along with the location, direction and duration of the hit. In a preferred form, the system also transmits a message remotely, such as to a parent's mobile phone, alerting and informing them how much force their child absorbed.
- Additional objects, features and advantages of the invention will become more readily apparent from the following detailed description of preferred embodiments thereof when taken in conjunction with the drawings wherein like reference numerals refer to common parts in the several views.

Sensor 135 is configured to detect an impact involvingprotective headgear 105.Sensor 135 is also configured to measure an angular position ofprotective headgear 105. To accomplish this,sensor 135 is preferably constituted by an accelerometer and a gyroscope (not separately labeled). Accordingly, it should be recognized that, in a more general sense,sensor 135 is configured to measure acceleration and orientation. -
Controller 140 is configured to use data fromsensor 135 to generate impact information by analyzing an impact toprotective headgear 105 and determining the susceptibility of the wearer to a concussion. Preferably, this analysis takes into account some or all of the magnitude, location, direction and duration of the impact.Controller 140 includes a transmitter (not separately labeled) that is configured to transmit the impact information to a computer of another user, e.g., to a smartphone or tablet of a parent or guardian. - In one embodiment, a LSM6DS3 inertial measurement unit (IMU) from STMicroelectronics® is employed as
sensor 135, andcontroller 140 is the Adafruit® Feather™ MO WiFi microcontroller. The LSM6DS3 IMU includes an accelerometer and a gyroscope with an 8 kb FIFO buffer and embedded processing interrupt functions. The LSM6DS3 IMU enables the detection of shocks, tilt, motion, taps and step counts and is capable of reading accelerometer data up to 6.7 kS/s and gyroscope data up to 1.7 kS/s for more accurate movement sensing. The LSM6DS3 IMU also has the ability to buffer up to 8 kB of data between reads, host other sensors and drive interrupt pins due to the built-in FIFO. Each pin has been broken out on the LSM6DS3 IMU, with one side of the board featuring power and I2C functionality and the other side featuring pins that control SPI functionality and interrupt outputs. - With reference now to
FIG. 4 , aforward axis 400 and atilt limit 405 are illustrated.Forward axis 400 represents the forward axis ofsystem 100, particularly ofprotective headgear 105.Protective headgear 105 is level inFIG. 4 , such thatforward axis 400 is horizontal. When a wearer tilts his or head downward,forward axis 400 rotates downward in adirection 410. Ifforward axis 400 rotates beyondtilt limit 405,audio device 130 emits a sound, as discussed above. Preferably, this functionality is controlled bycontroller 140. -
Tilt limit 405 is selected to reduce the risk of the wearer sustaining an injury, such as a concussion, by reminding the wearer, via the sound, to keep his or her head in a safer, more upright position.Tilt limit 405 is essentially a preset angle, defined relative to horizontal and/or vertical for example, to whichforward axis 400 can be compared using data from the gyroscope ofsensor 135. - Based on the above, it should be readily apparent that the present invention has particular applicability in addressing concussions sustained by children and youth who play contact sports. While certain preferred embodiments of the present invention have been set forth, it should be understood that various changes or modifications could be made without departing from the spirit of the present invention. In general, the invention is only intended to be limited by the scope of the following claims.
