摘要： The invention is a new device that will improve the radio link quality for low power wireless devices. An example application is for low power, miniaturized wireless sensor nodes that are statically deployed in a slowly varying environment or that have limited mobility. The device is a reconfigurable antenna that is novel in that it operates with very low (zero-order) energy in contrast to existing system that required both significant computational and DC power.

摘要： Disclosed is a compact reconfigurable channel emulator, which may be used to emulate severe fading environments and test wireless systems and subsystems for operation in severe channel environments. Examples include radios, coding schemes, diversity methods and antennas. In particular, the chamber is well suited to test hardware associated with wireless sensor deployments for these tend to be susceptible to severe fading scenarios. Moreover, the invention is significantly smaller than traditional testing instruments, and with its automation, reduces electromagnetic interference and electromagnetic compatibility testing time and costs.

摘要： A ground-based system that provides quasi real-time measurement and collection of snow-water equivalent (SWE) data in remote settings is provided. The disclosed invention is significantly less expensive and easier to deploy than current methods and less susceptible to terrain and snow bridging effects. Embodiments of the invention include remote data recovery solutions. Compared to current infrastructure using existing SWE technology, the disclosed invention allows more SWE sites to be installed for similar cost and effort, in a greater variety of terrain; thus, enabling data collection at improved spatial resolutions. The invention integrates a novel computational architecture with new sensor technologies. The invention's computational architecture is based on wireless sensor networks, comprised of programmable, low-cost, low-powered nodes capable of sophisticated sensor control and remote data communication. The invention also includes measuring attenuation of electromagnetic radiation, an approach that is immune to snow bridging and significantly reduces sensor footprints.

摘要： The Portable Ultrafine Particle Sizer (PUPS) invention is provided. The PUPS is an instrument which can measure particle number concentration for particle sizes under 200 nanometers in-situ. The PUPS is a compact design for quick mounting on vehicles. Size discrimination is accomplished using a compact reverse Differential Mobility Analyzer (rDMA). Particle charging is accomplished using corona ionization. Concentration measurements are completed using a unique flexible printed circuit board electrode which can be removed for cleaning, disposal or chemical analysis of collected particles at the end of its in situ measurement life.
