WCDMA payloads on fast-moving platforms, such as on satellites in Molniya orbits or on UAVs, will likely be added to the battlefield to assure the warfighter of reliable, ubiquitous communications. The algorithms for handoffs, timing, and Doppler correction suitable for near-Geosynchronous platforms will not be suitable for these fast movers. Power control algorithms may or may not be suitable. Th ...

WCDMA repeater payloads being developed for deployment on unmanned aerial vehicles will provide enhanced beyond line of sight coverage with guaranteed Quality of Service for the warfighter. To become a reality, these payloads will require deployable multiband base stations to serve as the ground infrastructure. The base station will be designed in this project, thereby enabling this network archit ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

We propose an innovative Pedestrian Automotive System for Enforcement and Safety (PASES) that combines commercial-off-the-shelf video or camera components and state-of-the-art microwave(radar) systems with sophisticated software that will not only provide more effective enforcement through effective evidentiary information, but will also enable predictive actions based on vehicle and pedestrian be ...

Spectroscopic ellipsometry is recognized as the gold standard in noncontact characterization of the refractive index and thickness of a thin optical film or film stack on a substrate. However, it suffers from a number of shortcomings, perhaps the most important of which is the time required to perform a single measurement. Moreover, manufacturers are interested in comprehensive evaluation of thin ...

To improve the at sea recovery of the Remote Multi-Mission Vehicle (RMMV), the Advanced Optical Systems (AOS) has teamed with Maritime Applied Physics Corporation (MAPC) to deliver a solution employing passive optical sensors capable of detecting 6DoF position with accuracies surpassing the human eye. The sensors are a key component of the proposed Autonomous Vehicle Recovery System (AVRS) that wi ...

The Navy is developing weapon systems capable of launching inert projectiles for long-range surface fire support and missile intercept applications. Inert projectiles offer significant logistical and safety advantages over conventional chemical propellants or explosive ordnances. The launch conditions of future hypersonic projectiles will put extreme mechanical and aerothermal loads on the project ...

The use of commercial off-the-shelf laser systems as weapons is increasingly becoming real. Battery operated visible and infrared lasers can be purchased with powers near 1-watt, sufficient to cause permanent eye damage. Future threats may include frequency agile lasers. It is critical that countermeasure systems provide laser eye protection (LEP) across the visible and IR waveband. Self-activatin ...

DynSan will collaborate with the Purdue University to develop and test an innovative, fast digital hydraulic valve design that is insensitive to working fluid contamination. The goal is to improve the reliability of fueldraulic systems on aircraft gas turbine engines and similar applications. Current fueldraulic systems use flapper-type Electro Hydraulic Servo Valves (EHSV) to control actuator pos ...

Polaris proposes to develop necessary hardware and algorithms for a Sky Polarization and Sun Sensor (SkyPass) in order to replace absolute localization information provided by Global Positioning System (GPS) for when GPS fails in a typical navigation solution. Additionally, this proposal includes an polarization-based approach to improve feature extraction and association processes for use in navi ...
