The present technology relates generally to protective helmets with non-linearly deforming members. Helmets configured in accordance with embodiments of the present technology can comprise, for example, an inner layer, an outer layer, a space between the inner layer and the outer layer, and an interface layer disposed in the space. The interface layer comprises a plurality of filaments, each having a height, a longitudinal axis along the height, a first end proximal to the inner layer, and a second end proximal to the outer layer. The filaments are sized and shaped to span the space between the inner layer and the outer layer. The filaments are configured to deform non-linearly in response to an external incident force on the helmet.

The present invention relates to an articulated mounting for a visor. The articulated mounting supports spectacles. The articulated mounting has a first arm and a second arm connected together at a first pivot; a first end of the first arm is pivotally connected to a second pivot which is connected to a base that is attached to the visor; a second end of the second arm is pivotally connected to a third pivot which is connected to a spectacle connector. The mounting includes a resistance means to assist with maintaining the spectacles on a wearer whilst the visor is displaced. The mounting includes at least one limiting means to restrict range of movement about at least one pivot.

There is disclosed a novel system and method for performance monitoring of athletes. In an embodiment, the system comprises a plurality of sensor modules mounted on different locations of an athlete, wherein at least one of the plurality of sensor modules is a master sensor module configured to interconnect with all other sensor modules to collect performance data for transmission to a computer system configured to collect the performance data. In an embodiment, a sensor module is housed in a cavity of a blade holder in at least one skate of a pair of skates worn by a hockey player.

A retention system comprises a shroud configured to be coupled to a helmet. The shroud includes a front surface and a rear surface and the shroud is configured to be coupled to an accessory device. A flexible element is coupled to the shroud and configured to at least partially secure the accessory device to the shroud. The flexible element extends through the front surface of the shroud.

A method for testing a helmet for effectiveness of user protection includes moving a load along a predetermined path, supporting a target body at an impact location in the predetermined path, the target body including a head model and a helmet disposed on the head model, and impacting the target body with a force generated by the moving of the load. The impacting of the target body entails contacting the target body with an impactor free to move perpendicularly and tangentially relative to a surface of the target body. The supporting of the target body is at least reduced, if not eliminated, before or during the impact of the impactor with the target body at the location. Forces generated are automatically measured or sensed during the impact of the impactor with the target body at the location.

A remote lighting system for a safety helmet operable with a vehicle lighting system. The system includes a vehicle portion and a helmet portion comprising a helmet brake light; a microcontroller in communication with the brake light; and a helmet transceiver in communication with the microcontroller. The vehicle portion includes a vehicle transceiver in wireless communication with the helmet transceiver; a gate in communication with the vehicle transceiver, and under a condition when a signal is received from the vehicle transceiver, operable to electrically connect the battery to the brake light of the vehicle lighting system; and an accelerometer in communication with the vehicle transceiver, and operable to send a signal indicative of vehicle acceleration to the vehicle transceiver. When a threshold level of deceleration is exceeded, the microcontroller sends a signal to the transceivers and the gate, causing a brake light of the vehicle lighting system to be illuminated.

A method for alerting a user of a first portable communications assembly that another user of a second portable communications assembly is within a predetermined distance includes the step of receiving a distance signal transmitted by the transmitter in the second portable communications assembly. A distance between the first and second portable communications assemblies based on the distance signal is calculated based on the strength of the distance signal or based on a time stamp embedded in the distance signal. An alert is emitted when the distance calculated between the first and second portable communications assemblies is less than the predetermined distance.
