Abstract: The systems and methods provided herein are directed to a device for tracking a jumper's elevation during a parachute jump. The device includes an active sensor for monitoring a distance to the ground, which is disposed at an angle and transmitted from the jumper's calf to reduce the chance of self-obstruction. The device notifies the jumper in one of several ways when a threshold elevation is reached, and may take additional automated actions at particular elevation thresholds.

Abstract: A communications headset system and method of use utilizing first and second headsets with integrated hearing protection for enabling users to wirelessly communicate when the hearing protection is engaged. Each headset is configured for placement onto a user's head and includes hearing protection cups that engage a user's ears and attenuate incoming sound waves external to the headset. The headsets include a first optical receiver that detects a light signal within a first receiving field-of-view and generates an incoming electrical signal corresponding to the light signal. A speaker converts the incoming electrical signal to an incoming audio signal, and then outputs the incoming audio signal as sound waves. A microphone converts outgoing sound waves to an outgoing electrical signal. An optical transmitter converts the outgoing electrical signal to one or more light signals and then broadcasts the one or more light signals within a broadcast field-of-view and a broadcast range.

Abstract: An appendage-mounted display apparatus comprising a device mount for attaching electronic devices and a cuff assembly that provides a uniform tension fit around a user's appendage. The cuff assembly comprises a multi-layer blend of soft and rigid components and a ratcheting lacing or strap system to achieve a customizable, non-slip fit that may be quickly and easily adjusted with one hand. The device mount may be adapted to accommodate a variety of electronic devices including mobile phones, smartphones, and other communication devices, portable computers, maps, audio and music devices, global positioning system devices, and other interactive electronic devices and displays, as well as paper maps, checklists, and other static forms of guidance and instruction. In addition, the device mount may include a rail system for attaching a flashlight and/or other tools.

Abstract: A load carriage connector and system for rapid mounting and demounting of a user-carried load. The connector utilizes two mating halves comprising a male connector half and a female connector half. The connector is configured to allow mating under various angles of approach, allowing the user to reliably couple the system even under conditions in which the user is unable to view the orientation of the connectors. Additionally, the configuration of the connector system allows the user to quickly and efficiently decouple the connector halves, even while under tensile or shear load.
