20150364635 | SINGLE PHOTON COUNTING - A single photon counting apparatus comprising a SPAD and a controller. The controller is operable to vary the operating parameters of the SPAD during use in response to a count rate detected by the SPAD. The operating parameters comprising at least one of the voltage across the SPAD during an active period, the voltage across the SPAD during a quench period, the duration of the quench period and the temperature of the SPAD. Particle characterisation instruments comprising the apparatus are also disclosed. | 12-17-2015 |
20150362421 | PARTICLE CHARACTERIZATION - The disclosure relates to methods and apparatus for detecting properties of heterogeneous samples, including detecting properties of particles or fluid droplets in industrial processes. Embodiments disclosed include a particle characterization method, comprising: suspending particles in a fluid; causing the suspended particles to flow past a two-dimensional array detector; illuminating the suspended particles as they flow past the two-dimensional array detector in the fluid; acquiring a plurality of images of the particles as they flow past the two-dimensional array detector in the fluid; and applying a particle characterization function to results of steps of acquiring a plurality of images for at least some of the suspended particles. | 12-17-2015 |
20120240665 | RHOMETER CONTROL SYSTEM - A rotary rheometer is disclosed that includes improved control logic. This logic can provide continuously sampled force control logic, compliance control logic, adaptive control logic, anti-windup logic, and/or inertial correction logic. | 09-27-2012 |
