A Drive Beam Micro-Pulsed Injector

Not Available Head-mounted displays (HMDs) play a vital role in military and commercial simulation and training systems. They allow the user to interact with and navigate through virtual worlds before encountering them for real. This has proven to save lives and increase effectiveness in military applications such as flight simulation, dismounted infantry simulation, hazardous materials handling, mission planning and rehearsal. Immersive HMDs also have valuable commercial applications in education, architecture, medicine, entertainment, virtual prototyping, teleconferencing, scientific and financial data visualization and web-based experiences. All of the previously existing motion-tracking technologies (magnetic, acoustic, optical, mechanical, gravimetric) have significant problems with jitter, latency, interference, line-of-sight, accuracy, and/or range. These deficiencies lead to simulator sickness which can erase all the benefits of the immersive application. In addition to HMDs, many other applications (i.e. weapon aiming, camera tracking, personal navigation, etc.), require improved tracking technology as well. InterSense has patented, developed, and successfully commercialized the world's first inertial and sensor-fusion-based motion tracking systems. This technology offers very low jitter and latency, large range, immunity to environmental interference, and high-quality motion prediction to combat latency in the computer graphics rendering system. In this Phase 1 SBIR, we propose to research the technologies for a new generation of micro-miniature integrated inertial measurement units, and appropriate calibration and sensor fusion algorithms. Capitalizing on recent advances in micro-machining technology, sensor fusion algorithms, and electronic packaging, the new InertiaCube¿ will offer substantially improved performance, smaller size, and lower manufacturing cost.
