Advanced binaural rendering of audio signals for virtual reality

The human system for generating virtual audio illusion is known as the head-related transfer function (HRTF), which is a response that characterizes how the ear receives a sound from a point in space.

To provide a better auditory virtual reality, Air Force scientists and engineers have developed an improved methodology for selecting an HRTF for the binaural rendering of audio signals that are perceived by a user to originate from a real-world spatial location.

Surface adhesion improvement via pulsed laser nanostructuring

Patterning the surface of a material can significantly improve its mechanical, chemical, or electro-optical qualities.

As an alternative to commonly used patterning techniques, Navy scientists have developed a patterning process with precision control that does not require hazardous chemicals. The method is ideally suited to imparting a pattern for adhesion purposes.

Improved security monitoring and defenses for wireless personal area networks

Air Force scientists are beefing up security around wireless personal area networks (WPANs) through precise manipulation of the physical layer preamble (or header) – the initial signal used in network communications to synchronize transmission timing between systems.

With this approach, a response pattern identifies the true transceiver class of the device under test.

Modular helmet-mask

Protective masks are currently used by the military and civilian entities for protection against chemical and biological contaminants. However, such masks often impose a substantial physiological burden on the wearer.

Army scientists and engineers have developed an improved modular helmet-mask assembly which includes a helmet, a face protection assembly, and a transparent, impact resistant lens.

Targeted endodontic microsurgery using 3D printed guides

The Air Force has invented a novel tool for perfecting the alignment of trephine drills during complex dental surgeries.

The new targeted-EMS technique can be used in areas where anatomical complexities render free-hand osteotomy and root end resection prohibitive. This approach uses 3D–printed surgical guides and trephine burs to achieve single-step osteotomy, root-end resection, and biopsy in these complex cases.

Guard bed for gas particulate filter in collective protection system

Collective protection (CP) air filters are designed to remove toxic compounds from the air in ground vehicles, field hospitals, command posts, and ships, as part of an overpressure system. This creates a toxic-free area for personnel during nuclear, biological, or chemical weapon attacks.

While effective at removing toxins, CP filters can be degraded by common ambient air contaminants. To address this situation, a team of Army and Navy researchers developed an initial filter situated upstream of the CP, which can remove filter degrading compounds.
