| 20100233969 | RECONFIGURABLE CHAMBER FOR EMULATING MULTIPATH FADING - 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. | 09-16-2010 |

| 20120099105 | Portable Ultrafine Particle Sizer (PUPS) Apparatus - 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 The PUPS has a compact design which allows it to be mounted on vehicles with relative ease. Size discrimination is accomplished using, a compact reverse Differential Mobility Analyzer (rDMA) Particle charging is accomplished using a low-cost method for corona ionization. Concentration measurements are completed using a unique flexible printed circuit board electrode which can be easily removed for cleaning, disposal or chemical analysis of collected particles at the end of its in situ measurement life. | 04-26-2012 |

| 20110073771 | DISTRIBUTIVE, NON-DESTRUCTIVE REAL-TIME SYSTEM AND METHOD FOR SNOWPACK MONITORING - 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. | 03-31-2011 |

| 20080249734 | Method of Making a Decision on the Status of a Mechanical System Using Input and Response Data Acquired In Situ - An in-situ monitoring system is engaged with a mechanical system for which it is desired to assess or monitor the in-situ performance of the mechanical system. The in-situ monitoring system includes at least one input sensor and at least one output sensor for collecting data corresponding, respectively, to input into, and output from, the mechanical system. The monitoring system also includes an analyzer that utilizes the input and output data to generate an in-situ response representation of the mechanical system. The in-situ representation may be used to make a decision regarding the status of the mechanical system, e.g., to replace all or part of it, to adjust it or to do nothing. In one embodiment, the analyzer is programmed to adapt to the operating conditions of the mechanical system by automatically selecting which one of a number of target representations should be used to characterize the in-situ representation. | 10-09-2008 |

| 20110120815 | Braking System for Patient Support - An assembly controls brakes on beds for use in healthcare facilities. The bed comprises at least one caster device supporting a base frame in relation to a supporting surface. The caster device has a caster brake. A brake control assembly is operatively engageable with the caster brake to engage the caster brake. The brake control assembly comprises a sensor for sensing a status condition of the caster brake. A controller is connected to the sensor. The controller causes engagement of the caster brake when the sensor senses the status condition for a predetermined period of time. | 05-26-2011 |
