Systems and methods are provided for determining an acceleration at a location of interest within one of a user's head and neck. At least one of linear acceleration data, angular acceleration data, angular velocity data, and orientation data is produced using at least one sensing device substantially rigidly attached to an ambient-accessible surface of the user's head. The location of interest is represented relative to a position of the at least one sensing device as a time-varying function. An acceleration at the location of interest is calculated as a function of the data produced at the sensing device and the time-varying function representing the location of interest. The calculated acceleration at the location of interest is provided to at least one of the user and an observer in a human-perceptible form.

The present invention relates to a device that stabilizes or protects the head or spine from injuries. An immobilization device includes one or more pillars with multiple segments that protect the head or spine of a user. The pillars typically run along the part of the head and spine and pelvis that the device protects. A cable or wire runs through these segments in the pillars. By design, when the pillars of the invented system are not activated and the system is in normal use, the pillars are designed to be as flexible as possible and allow full physiologic motion of the protected body part. Activation of the system confers rigidity to the system and prevents or lessens harmful, non-physiologic motion of the body part intended to be protected. The present invention can further include a caudal extension used to connect to vehicle.

Helmets and helmet lighting systems for use in demanding environments, such as fire, rescue, police and military applications. The helmets and systems provide one or more of high levels of light emission, long operational life, waterproofing/ability to operate in wet or submerged environments and relatively low weight. In some configurations, a helmet comprises a lighting system including an exterior layer and an interior layer applied to a shell of the helmet. In some configurations, a lighting module having an internal layer and an exterior layer is attached to an underlying helmet. In some configurations, a lighting system includes pods and/or strips containing a source of light. The pods or strips can be attached to an underlying helmet.

A wearable device is configured for use with a headgear for detecting impact forces on the user's head. The device has a flexible structure, including a top cover, and a bottom cover, a battery and an electronic circuit which is electrically connected to the battery, wherein the top cover, bottom cover, battery and electronic circuit are positioned in a stack and laminated together forming a flexible moisture proof device. The present disclosure relates also to an arrangement having a wearable device.

A brain injury reduction system provides a protective measure that temporarily or decreases venous drainage out of the intracranial compartment during or immediately before and during a sudden change in acceleration of an individual's head. Specifically, a wearable helmet or other wearable structure of the brain injury reduction system detects an impending collision and determines whether a protective measure is needed. If so, one or more actuation devices provides the protective measure to reduce venous drainage through one or both of the internal jugular veins or paravertebral venous plexus. A first actuation device stimulates a gag reflex or valsalva-like maneuver to reduce venous drainage through the paravertebral venous plexus. A second actuation device can physically compress the internal jugular veins. Thus, the brain injury reduction system minimizes the detrimental impact that may occur due to the sudden change in acceleration of the individual's head.

A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids is provided. The system includes a head unit shaped to be worn over the head of the wearer; a hood positioned over the head unit; one or more sensors configured to produce one or more sensor-output signals; and a controller connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

A helmet has a helmet shell and a visor pivotally connected to the helmet shell. The helmet further has an electrical device attached to one of the visor and the helmet shell. First and second helmet electrical contacts are attached at both sides of the helmet and are adapted for electrically connecting to an electrical power source. First and second visor electrical contacts are attached to each side of the visor and are electrically connected to the electrical device. The first and second visor electrical contacts are pivotally connected to the helmet shell about first and second pivot axes respectively. The first and second visor electrical contacts are in contact with the first and second helmet electrical contacts respectively, at at least one position of the pivoting visor.

The present disclosure provides sports apparatus including sports headwear and an impact detection arrangement for coupling to the sports headwear, e.g. a rugby scrum cap, to be worn by a user. The arrangement has a sensor for detecting an indication of an acceleration change experienced by the user's head when the sports headwear is being worn. The arrangement also has a visual indicator, e.g. an arrangement of LEDs, to provide a visual indication when the detected acceleration change exceeds a threshold. Advantageously, the present disclosure allows for immediate attention to be drawn to a player who has experienced a high g-force to their head, and therefore immediately alerts anyone in the vicinity that a medical check is needed to assess symptoms caused by the impact.

Example hard hat adapters include: a coupling mechanism to removably couple the hard hat adapter to a hard hat; an upper arm configured to removably couple to an outer face shield and an inner face shield; and a lower arm configured to removably couple to a blower shell, wherein the outer face shield and the inner face shield are configured to removably couple to the hard hat adapter at a first pivot point of the hard hat adapter.

Exemplary embodiments of the present disclosure are directed towards helmet systems and methods for detection and notification of objects present in the blind spot. They detect objects through ultrasonic sensors and notify the presence of those objects through sensory output modules such as LED output modules, vibration motors and speakers. The helmet system comprises of at least one helmet body, at least two ultrasonic sensors positioned at the left and right side of at least one helmet body to cover a blind spot on the left and right side of a user, at least two LED output modules positioned at the right and left side of the front of at least one helmet body. at least two vibration motors which are concealed on either side of the helmet body and at least two vibration motors configured to generate the different patterns of an haptic feedback based on the different signals generated by at least two ultrasonic sensors. At least two speakers are positioned at the right and left side of at least one helmet body and at least two speakers are configured to give an audio feedback. And at least one processing device electrically coupled to at least two ultrasonic sensors, and at least two LED output modules, at least two vibration motors and at least two speakers. At least two ultrasonic sensors are configured to detect objects in the blind spot region and at least one LED output module and at least one vibration motor and at least one speaker configured notify the presence of the objects.
