Systems are described for monitoring extremities for injury or damage following a physical impact. A device embodiment includes, but is not limited to, a deformable substrate; a sensor assembly coupled to the deformable substrate, the sensor assembly configured to generate one or more sense signals based on detection of a physical impact to a body portion and based on detection of a physiological parameter; circuitry operably coupled to the sensor assembly and configured to receive the one or more sense signals based on detection of the physical impact and to determine whether the physical impact exceeds a threshold impact value, the circuitry configured to instruct the sensor assembly to detect one or more physiological parameters of the body portion when the physical impact exceeds the threshold impact value; and a reporting device operably coupled to the circuitry.

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 suspension band assembly to be used to support a hard hat on a head of a user. The suspension band assembly includes a primary support loop to receive the head of the user therein. An electronic peripheral is fixedly secured to the primary support loop. An attachment strap extends out from the primary support loop to a strap distal end. An anchor is fixedly secured to the strap distal end for securing the attachment strap to the hard hat. An electrical anchor contact is fixedly secured to the anchor to provide an electrical connection between the hard hat and the electronic peripheral located on the primary support loop.

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 safety helmet (100) includes a helmet shell (7), with a bearing support structure (2, 5, 9, 21), with a helmet-side coupling point and with a module adapter (1). The bearing support structure (2, 5, 9, 21) is fastened to the helmet shell (7) on an inside. A helmet-side adapter coupling point of the module adapter (1) can be connected detachably to the safety helmet-side adapter coupling point of the module adapter (1). The module adapter (1) holds a module at the safety helmet (100). A process for fastening a module detachably to a safety helmet (100).

A helmet including a lighting system integrated into said helmet, the lighting system comprising a first layer; light emitting means mounted to said first layer; controller means mounted to said first layer for controlling said light emitting means; wiring means for linking said light emitting means to said controller means; a second layer fixably attached to said first layer thereby providing an area between said first and second layer for said light emitting means, controller means, and wiring means; power means fixably attached to said second layer for powering said controller and light emitting means; and operating means functionally linked to said controller means for operating said controller means. The application also discloses lighting system contained in a shell that that can be attached to an existing helmet. This application also discloses a lighting system contained in a flexible material that can be fitted onto an existing helmet.

A head unit system for a head of a user, including a headpiece including a support structure shaped to be worn over the head. A shield mount attached to the support structure is arranged for supporting a face shield adjacent to the head. A headpiece connector is attached to the support structure and has a headpiece contact configured for electrical connection. A peripheral device provided for being secured to the headpiece for concurrent movement, the peripheral device having a device connector with a device contact configured for electrical connection. The device connector and the headpiece connector cooperate to releasably attach the peripheral device to the headpiece in a secured configuration with the respective headpiece contact and the device contact abutting in the secured configuration so as to facilitate electrical connection between the headpiece and the peripheral device.
