Abstract: Provided are systems and methods for accurate sensing of particle concentrations in fluids by employing a particle impactor system that allows for collection, growth and analysis of biological particles. The disclosed systems and methods make use of a pressure based flow sensor which permits the particle impactor system systems to accurately and reliably provide measurements of biological particle concentrations in the ambient environment. By incorporation of pressure sensors and pressure measurements into the flow measurement techniques, embodiments provide for the ability to use a particle impactor system to accurately measure environmental biological particle concentrations at a variety of atmospheric pressure conditions, such as at high altitude or with minimal perturbation from atmospheric weather conditions, without requiring recalibration or other adjustment of the sensors and control systems.

Abstract: Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. A gas source can be provided in a cartridge which is used to generate gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the gas source and mixed with the precursor liquid to form a beverage.

Abstract: Provided are devices and methods for monitoring flow rate in aerosol particle counters. The particle sensor has a particle counter, a flow measurement orifice comprising a differential pressure sensor for measuring differential pressure (DP) across the flow measurement orifice during particle sensor operation and a critical flow orifice. A vacuum source pulls ambient gas through each of the particle counter, flow measurement orifice and critical flow orifice. An atmospheric pressure sensor measures atmospheric pressure (AP) and a bench pressure sensor measures pressure in the particle sensor (BP). The output from the sensors is used to identify a flow condition, such as by a monitor operably connected to each of the differential pressure sensor, atmospheric pressure sensor and bench pressure sensor. In this manner, deviation in flow rate from a target flow rate is readily monitored without the need for expensive sensors or other flow-controlling components.

Abstract: The present invention relates to a sealing wafer (1) adapted to be arranged in a stoma receiving hole (5) of a base plate (2) comprising an attachment platform extending from an outer edge adapted to be attached to the base plate towards an inner edge defining a through-going hole (17) for receiving a stoma, the sealing wafer further comprising at least a first urging part extending transversely from the proximal surface facing towards the user during use of the attachment platform and wherein the first urging part is resilient in the direction transverse to the proximal surface. This provides a sealing wafer which is particularly suitable for use with a stoma around which the skin has an uneven curvature, such as a retracted stoma wherein the stoma has pulled back resulting in a crater-like area.

Abstract: A particle measurement system using a single component light collecting system with an aperture having a portion within direct view of the light detector. An aperture assembly extending into a sample may be self-concealing by having an extended portion to block light from directly illuminating the light detector. Alternatively, a smooth, reflective inside surface of the aperture assembly provides for self-concealment by causing spontaneous emitted light to have low angles of reflection. In either case, spontaneously emitted light is substantially prevented from reflecting directly into the light detector, thereby reducing light noise to the level of molecular noise.
