Systems, methods, and computer-readable media are described for predicting a neurological injury to a participant in an activity. The activity can be, for example, an athletic activity that involves repeated, high-impact collisions between participants. Sensor data reflecting interactions between participants in the activity is received from various wearable and non-wearable sensors. The sensor data is evaluated in conjunction with a baseline neurological risk profile of a participant to determine a likelihood that the participant has suffered a potential neurological injury. If this likelihood meets a threshold risk level, an onsite request/response test is initiated to glean more information relating to the participant's condition. Response data associated with the onsite test is cognitively evaluated to determine an updated likelihood of neurological injury to the participant and a follow-up action is determined based on the updated likelihood of neurological injury.

A headgear apparatus is disclosed comprising a molded headgear apparatus which includes a cushioned core component to provide impact resistance during an activity. The headgear is configured to be low-profile to reduce the loss of vision caused by thick headgear which extends away from the face. The headgear may be molded to the facial contour of the user to provide complete protection from cuts, scrapes, swelling, and impact encountered in impact sports, such as martial arts, football, or other sports wherein impact to the head region is possible.

A head-mounted device capable of more highly accurately measuring the physical conditions of a wearer as a worker that are necessary for estimating the possibility of heat stroke is provided. A head-mounted device includes an outer shell; a first channel as a gap between a head of a wearer and the outer shell; a second channel provided in the outer shell and connected to the first channel; a fan configured to send air from one of the first channel and the second channel to the other; a salinity sensor configured to measure salt concentration of sweat of the wearer; a first humidity sensor configured to measure an absolute humidity of intake air entering one of the first channel and the second channel; and a second humidity sensor configured to measure an absolute humidity of exhaust air exiting from the other of the first channel and the second channel.

A method for alerting a user of a wearable airbag system. The method includes the steps of ensuring that the airbag system is active, checking the current location of the airbag system, calling a server storing a plurality of locations, each location being associated with an increased risk for an accident, and if the current location of the airbag system is close to a stored location, further performing a step of alerting the user.

A jammer system includes a jammer unit, a valve coupled to the jammer unit, and a sensor coupled to the valve. The jammer unit includes a jammer media and a membrane including an inlet. The membrane is configured to surround the jammer media. The valve is configured to allow a fluid to pass through the inlet of the membrane. The sensor is configured to cause actuation of the valve to evacuate the fluid from an interior of the membrane. The evacuation of the fluid from the interior of the membrane results in stiffening of the jammer media within the membrane.

An apparatus, system and method for ski training are disclosed herein for providing feedback to a skier regarding the orientation of their skis. The apparatus, system and method measure various distances between a first ski and a second ski, determine an angle between the first ski and the second ski based on information representative of various distances; and provide an indication of the measured angle.

An apparatus and methods for impact detection are disclosed. Example apparatus comprises a plurality of sensors. The apparatus is configured to determine whether a user is wearing an item in which the apparatus is comprised, and in response to a positive determination, operate the apparatus in an active operating mode. The active operating mode comprises operating one or more sensors in the plurality to generate data associated with motion of the user at a first sampling rate.

The flexible electronic control unit 61 for helmet strap with safety, emergency and driving assistance functionalities can be installed around helmet strap 62, independently from helmet configuration. The electronic control unit is structured to execute Emergency Call or its equivalent in case of accident or fall, taking account of the related European and International regulations, with real-time transmission of user's blood pressure profile and/or derived measures to PSAP and the like while emergency call is ongoing as to support rescue organization. The electronic control unit implements also driving assistance functionalities and remote connection with vehicle control units, such as the peculiar generation of sound alert to reduce vehicle speed as a consequence of uneven bumpy street asphalt detection, as well as the peculiar generation of a synthetized voice message to the user for indications coming from the vehicle about adherence conditions and further information about its own status while travelling.

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.

An infrared motorcycle helmet device is provided. The infrared motorcycle helmet device includes a helmet. The helmet has an opening on a front portion of the helmet. An external visor is placed on an external surface of the helmets. The external visor can be moved into a position over the opening as desired. An infrared camera is placed on an external surface of the helmet.
