Semi Autonomous Systems

Large system engineering experience including working on the US Navy’s Remote Minehunting System (RMS)* addressing vulnerability and propulsion requirements and power takeoff/system optimization by developing innovative methods of analyzing acoustic noise in a variety of vehicles with world renowned experts to conduct reduction in noise, electromagnetic, infrared signature vulnerabilities; applying expertise in designing vehicles for electric, hydraulic, fuel cells, closed brayton-cycle and diesel energy sources and designed modular energy system for mission performance requirements, integrating cast structural/cooling schemes for energy modules. Experienced in complete redesign of power generation system, reducing part count, weight and life-cycle-cost while increasing efficiency.

Critical Solutions are possible when team has experienced and creative talent on the team. For a diesel-powered AUV, when sea trials uncovered propulsor acoustic cavitation and an outside expert recommended a complete redesign, impacting both cost ($2M) and schedule (1 Year program delay) team member initiated a sisuroot-cause analysis, developed at sea test plan, experimentation and instrumentation methods developed a permanent solution, saving program from default. Again during sea tests, when the Diesel-powered crank nose failed the principal uncovered sisuroot cause, developed a torsional flex coupling, analyzed in a test cell, and implemented within six months for successful at-sea testing.

*The Remote Minehunting System (RMS) provides the primary mine reconnaissance capability in the Navy’s Littoral Combat Ship (LCS) Mine Countermeasures (MCM) Mission Package. RMS addresses a critical Mine Warfare gap - using unmanned, offboard systems to detect, classify, localize and identify bottom and moored mines in littoral regions - without putting sailors or high-value capital ships in the minefield. It uses an unmanned, autonomous Remote Multi-Mission Vehicle (RMMV) that tows an advanced Variable Depth Sensor (AQS-20A) that supports minehunting sensors. The RMMV can operate at great distances (over the horizon) with 24-hour endurance. No other unmanned system available today has demonstrated the capability or maturity of RMS for persistent, high search rate mine reconnaissance. The RMMV has undergone rigorous reliability testing, completing 1300 hours of at-sea testing during the RMS Reliability Growth Program.

Fully Autonomous Vehicles

Experience with US Navy’s Advanced Development Unmanned Underwater Vehicle (ADUUV) and its test bed to integrate Littoral Precision Underwater Mapping Array (LPUMA) sensor into the ADUUV as well as MRUUV ($250M) applying novel manufacturing, engineering processes, CAE tool development, ballast design, thermal management, acoustic treatments, configuration management, propulsive design, energy sources, & modular instrumentation.

Mission Persistent Autonomous Vehicles

Using and Integrating experience with a Liquid Robotics Wave Glider** instrumented with current profiling instrumentation to characterize the available resource in the Florida Current for marine hydrokinetic devices.

*The Wave Glider harvests energy from ocean waves to provide essentially limitless propulsion, ensuring the continuous presence in the oceans. The glider is composed of two parts, the surfboard-sized float, and a subsea glider equipped with a series of pivoting, horizontal wings. Connected by a unique umbilical tether, the float rides on the surface and the glider remains below the surface, where it is protected. Wave Gliders are equipped with a sophisticated computer for navigation and payload control, satellite communication systems, and state of the art ocean sensors to measure the environment around it. The power needed to operate the sensors and computers is provided by solar panels and rechargeable lithium-ion batteries. The tethered separation between surface float and subsea glider harvests wave energy and transforms it into forwarding thrust. An auxiliary thruster can provide additional thrust when needed. The Wave Glider platform is flexible and supports a growing array of sensors able to collect a wide variety of scientific and commercial data.

Computer Vision : Threat detection

Experience developing 3D X-Ray Threat Detection Systems* (including High Voltage Power Supply development enabling dual energy) and collaborating with GE Healthcare to provide platform cost reduction via direct material/DMP and variable cost productivity working with cross-functional computer vision, mechanical and electrical engineering disciplines (PCBs, firmware, data acquisition systems, High Voltage, Slip Rings, Heat Exchangers, CAE tools…)

*Capable of screening 1,800 bags per hour (BPH), the CTX 9800 enhances operational efficiencies by combining high-resolution 3D visuals with intuitive navigational tools – allowing the operator to ‘travel’ through the bag and manipulate images. Designed for a wide variety of airport applications the CTX product line offers TSA certified detection for both standalone and baggage handling systems integrated , inline applications. CTX machines use technology derived from medical computer Tomography (CT) to help locate and identify explosive devices concealed in check baggage
