| 20100083737 | DEVICE FOR MEASURING SUPERFINE PARTICLE MASSES - A device for measuring superfine particle masses including a quartz oscillator and an exposure system having at least two measuring chambers. Each of the at least two measuring chambers has a same geometry, a deposition surface for particles, and an aerosol feed directed at the respective disposition surface configured to feed an aerosol onto the respective deposition surface. At least one of the respective deposition surfaces is disposed on the quartz oscillator. | 04-08-2010 |
| 20140305191 | RESONANT FIBER BASED AEROSOL PARTICLE SENSOR AND METHOD - The present invention relates to methods and devices for determining the weight of small particles, typically being nano-sized particles by use of resonating fibers in the form of elongate members being driven into resonance by an actuator or e.g. thermal noise/fluctuation. The frequency shift in resonance frequency due to depositing of nano-sized particles is correlated with the mass deposited on the elongate member and the vibration frequency of the elongate member is determined by a detector. The read-out from the detector is transformed into a mass deposited on the elongate member. Particles are deposited by letting a fluid with the particles flow past the elongate member. | 10-16-2014 |
| 20150059443 | MEASURING DEVICE - A measuring device for measuring dust in flue gas of small-scale furnace installations for solid fuels includes: a measuring probe; a weighing device having a filter device; a heated suction hose connecting the measuring probe to the weighing device; and a weighing module in which the weighing device is arranged. The weighing device is thermally insulated in the weighing module. | 03-05-2015 |
| 20150107335 | Acoustic Particulate Concentration Methods and System - A process is disclosed for using multiple acoustic resonators to sample fluids (gas or liquids), capture particulate (or aerosols) entrained in the fluid, and deliver a concentrated sample of particulate. The acoustic concentrator demonstrates many improvements over prior art that includes improved concentration of particulate below | 04-23-2015 |
| 20160047728 | MEMS AEROSOL IMPACTOR - Embodiments of the invention include aerosol impactors comprising one or more micromechanical resonators. Impactors according to embodiments of the invention can provide size classification and/or concentration of aerosol particulate. Aerosol impactors can use an air flow device, such as a pump, to create a constant flow of air. Nozzles of varying diameters are used to separate particulate of varying sizes and the particles that pass through strike a measuring device. MEMS resonators can be integrated into arrays to provide mass sensitivity in a small, lightweight and cost effective package, which will effectively allow for the measurement of the mass of every micro/nanoscale particle landing on the surface. | 02-18-2016 |
| 20160069822 | METHOD AND DEVICE FOR DETERMINING AT LEAST ONE CONCENTRATION OF COAL PARTICLES IN A GAS FLOW - The present embodiments relate to a device and a method for determining at least one concentration of coal particles in a gas flow flowing through a channel, wherein at least part of the gas flow having coal particles contained therein is measured by at least one microwave sensor and at least one measurement signal characterizing the concentration of the coal particles is provided, wherein an autocorrelation function of the measurement signal is determined and at least one distance value characterizing a distance of a point of the gas flow belonging to the concentration from the microwave sensor is determined in dependence on the autocorrelation function. | 03-10-2016 |
| 20160377466 | DETECTION FOR LOCALIZING A PARTICLE - Detection for localizing at least one particle moving in a flow includes emitting a transmission signal by a transmitter, and receiving a reflected reception signal. The reflected reception signal is frequency and phase modulated in comparison with the transmission signal. The reflected reception signal is convolved with at least one kernel representative of a conjugate estimated channel pulse response. A reconstructed particle position function is formed, and the position of the particle is determined from the reconstructed particle position function. | 12-29-2016 |
