摘要： A seed dispensing system is provided with a photoelectric sensor for monitoring the dispensing of seeds from a seed dispenser comprising a discharge conveyor with conveyor flights that transport seeds through the seed dispenser. The sensor outputs a signal representative of obstructions to the flow of light in an optical path of the sensor, and a computing unit is adapted to distinguish portions of the output signal that are attributable to the passage of one or more seeds from portions of the output signal that are attributable to the passage of a conveyor flight.

摘要： A fluid system includes a capillary and a first and second temperature sensor, a first and second pressure sensor, and a processor coupled to the sensors. The processor is configured to execute instructions to determine an output using the sensor data and using fluid parameter data received via an interface coupled to the processor. The processor is coupled to a control in fluid communication with the capillary.

摘要： The disclosed subject matter compensates or corrects for errors that otherwise would be present when a measurement is made on a condensation particle counting system with the only difference causing the errors being absolute pressure. The difference in absolute pressure may be due to, for example, a change in altitude in which the condensation particle counting system is located. Techniques and mechanisms are disclosed to compensate for changes in particle count, at a given particle diameter, for changes in sampled absolute pressure at which measurements are taken. Other methods and apparatuses are disclosed.

摘要： A measurement system includes an atomizer, an impactor, a particle counter, and a discharge reservoir. The atomizer has a liquid intake port and a gas intake port configured to aerosolize a liquid received at the liquid intake port. The impactor has an inlet coupled to the atomizer and has a first output port and a second output port. The impactor is configured to separate droplets wherein those droplets smaller than a selected cut point are directed to the first output port and those droplets larger than the selected cut point are directed to the second output port. The particle counter is coupled to the first output port and is configured to count particles larger than at least one particle size cut point. The discharge reservoir is coupled to the second output port.

摘要： An apparatus and method for use in determining one or more fluid flow properties of a fluid in a conduit is disclosed. The apparatus includes a substrate including a barrier, a first flow sensor coupled to the substrate and a second flow sensor coupled to the substrate. The first flow sensor is located at a first sensor distance from a first barrier surface, and the second flow sensor is located a second sensor distance from the second barrier surface. The first sensor distance is substantially equal to the second sensor distance. In operation, the first flow sensor produces a first sensor signal, and the second flow sensor produces a second sensor signal. The direction of flow for the fluid is determined by comparing the first sensor signal to the second sensor signal.

摘要： Various embodiments include an exemplary design of an apparatus and related process to reduce or eliminate de-gassing from a liquid precursor during dispensing of the liquid precursor under vacuum. In one embodiment, the apparatus includes a liquid-flow controller configured to be coupled to a liquid-supply vessel containing the liquid precursor, and at least one valve hydraulically coupled downstream of and to the liquid-flow controller by a liquid line. The at least one valve is to be opened and closed to maintain a minimum pressure that is sufficiently high enough to reduce or prevent degassing of the liquid precursor throughout the liquid line. An atomizer is hydraulically coupled downstream of and to the at least one valve. The atomizer can produce droplets of the liquid precursor and is further to be coupled on a downstream side to a vacuum source. Other methods and apparatuses are disclosed.

摘要： Various embodiments include methods and apparatuses to reduce false-particle counts in a water-based condensation particle counter (CPC). In one embodiment, a cleanroom CPC has three parallel growth tube assemblies. A detector is coupled to an outlet of each of the three parallel growth tube assemblies, and is used to compare the particle concentrations measured from each of the three growth tube assemblies. An algorithm compares the counts from the three detectors and determines when the particles counted are real and when they are false counts. Any real particle event shows up in all three detectors, while false counts will only be detected by one detector. Statistics are used to determine at which particle count levels the measured counts are considered to be real versus false. Other methods and apparatuses are disclosed.

摘要： There is disclosed a handheld air flow velocity measurement probe that includes a bridge circuit assembly having an airflow velocity sensor that is a resistance temperature detector (RTD) and a digitally controlled resistive element to dynamically adjust and maintain the resistance of the velocity sensor within the overheat temperature predefined range. The velocity measurement also uses a separate temperature sensor to sense the temperature of the air or gas flow. A humidity sensor is also included remote from the other sensors to measure humidity in the gas flow to be measured. All of the above described components are housed at a probe tip instead of a base as in most standard handheld probes and the digital interface at the probe tip allows the user to replace a bulky, expensive telescoping antenna with stackable extender scheme.

摘要： The electrospray generator system described herein uses a soft X-ray source instead of a radioactive source to generate bipolar ions for the neutralization of the initially charged particles. In one example, the soft X-ray source is directed at an orifice from which the charged particles emanate, thereby allowing the neutralization of the particles to happen faster than in prior art configurations and, in some instances, even neutralization occurring immediately on a droplet before it passes through the electrospray orifice.
