The present disclosure describes clips for lanyards, such as hard hat lanyards. The clips include opposing teeth that move to a closed/clamped position to secure a lanyard to a user, such as to the clothes of a user. The clip includes a body, a lever and a grip. Opposing teeth are located on the grip and body. The clip includes multiple pivoting connections between the body, lever and grip. The teeth on the grip may lie along an arcuate path and/or may have a tooth depth that facilitates engagement with material such as clothing.

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.

An apparatus and method for displaying an operational area to an operative of a host platform, said operational area being defined within an external real-world environment relative to said host platform, the apparatus comprising a viewing device (12) configured to provide to said operative, in use, a three-dimensional view of said external real-world environment, a display generating device for creating images at the viewing device, and a processor (32) comprising an input (34) for receiving real-time first data representative of a specified target and its location within said external real-world environment and configured to receive or obtain second data representative of at least one characteristic of said specified target, the processor (32) being further configured to: use said first and second data to calculate a geometric volume representative of a region of influence of said specified target relative to said real-world external environment and/or said host platform, generate three-dimensional image data representative of said geometric volume, and display a three dimensional model, depicting said geometric volume and created using said three-dimensional image data, on said display generating device for creating images at the viewing device, the apparatus being configured to project or blend said three-dimensional model within said view of said external real-world environment at the relative location therein of said specified target.

A helmet accessory mount system may include a shroud configured to be coupled to a helmet and an arm assembly having a first arm configured to rotatably couple to the shroud. The system may also include an accessory interface configured to coupled to an accessory and configured to engage the arm assembly. The arm assembly may be configured to move from a deployed position to at least one storage position. The accessory may be configured to be positioned between the accessory interface and the helmet when the arm assembly is in the at least one storage position.

An apparatus can include a cushion including an expanded PTFE layer and a frame that can include two lateral portions and a bridging portion therebetween. The lateral portions and the bridging portion can define a concave surface that is coupled to the cushion to support and provide a concave contour to the cushion.

Rider location and acceleration sharing systems are provided herein. For instance, a system is paired with a wireless transceiver, mountable to or within headwear that outputs location data and accelerometer data associated with the user identity to a user device. Once members of the group of user devices are validated for movement together, an emergency event associated with a member of the group may be identified based on the accelerometer data or the location data, and, in response to the emergency event, emergency event data is sent to the respective other user devices, and other information is enabled to be received from any of the respective other user devices.

A helmet configured to be worn by a wearer that includes an outer shell, an inner liner positioned inside the outer shell, a data collection assembly that includes a first data collection member for measuring impact data, and a second data collection member for measuring vital signs data.

In an aspect, a stress mitigation system is provided for mitigating stresses in a wearer of a headgear configured to apply a load on the wearer that is offset from a center of gravity of the wearer's head to apply a first torque in a first direction on the wearer's head. The system includes a track, a shuttle, and a flexible elongate connector. The track is mounted to either the headgear or a bodywear member and extends generally laterally. The shuttle is movable along the track. The connector is configured to connect between the shuttle and the other of the headgear and the bodywear member. The connector applies a second torque on the headgear in a second direction that is generally opposite to the first direction. When the wearer's head pivots, the shuttle is movable laterally along the track to maintain the connector in a substantially vertical orientation.

The present invention achieves technical advantages as an aircraft having an augmented reality flight control system integrated with and operable from the pilot seat and an associated pilot headgear unit, wherein the flight control system is supplemented by flight-assisting artificial intelligence and geo-location systems. The present invention includes an augmented reality flight control system incorporating real-world objects with virtual elements to provide relevant data to a pilot during aircraft flight. A translucent substrate is disposed in the pilot's field of view such that the pilot can see therethrough, and observe virtual elements displayed on the substrate. The system includes a headgear that is worn by the pilot. A flight assistance module is configured to receive ii data related to the aircraft and provide predictive assistance to the pilot during flight based on the received data based in part on a pilot profile having preferences related to the pilot.
